Management of mental health disorders in people with MS

15/02/2026 Gavin Giovannoni

Emotional problems in people with MS must be recognised, addressed and treated, rather than dismissed as an inevitable consequence of living with this chronic condition.

Key points

An MS diagnosis naturally triggers emotions similar to the stages of grief (denial, anger, bargaining, depression, acceptance); in addition, the unpredictability of MS causes anxiety in many patients.
Anxiety, often combined with depression, is linked to a poorer quality of life, cognitive dysfunction, increased risk of suicide, and significant occupational and social problems.
Emotional problems in MS are typically exacerbated by fatigue, pain and poor sleep – all of which interfere with therapy and lifestyle adjustments.
Emotional changes in MS require treatment, just as physical symptoms do. This should comprise routine screening, targeted drug treatment and structured psychological and behavioural therapies.
Motivational coping styles that involve direct problem-solving and active participation in treatment planning (i.e. self-management) help people with MS adjust to their diagnosis.
Avoidance coping strategies generally lead to poorer psychological outcomes.
The presence of social support is a critical protective factor.

Impact of emotional changes

Emotional disorders have an adverse effect in people with MS, potentially impairing their ability to cope with disability and reducing overall health-related quality of life. Living with MS can also adversely affect relationships, for complex reasons, including both emotional and physical problems associated with the disease. Therefore, such symptoms must be recognised, addressed and treated, rather than dismissed as an inevitable or acceptable consequence of living with a chronic condition such as MS.

Emotional disturbances in people with MS may be reactive, i.e. a natural, adaptive psychological response to being diagnosed with a long-term, unpredictable and potentially disabling disease. Common emotions include grief, sadness, worry, fear, irritability and moodiness. Elisabeth Kübler-Ross in 1969 described five common stages of grief, best known by the acronym DABDA. We have added an extra A, for Anxiety about the future, to include the emotional reaction to a diagnosis of MS. The expands the mnemonic to six stages: DABDAA.

Denial, Anger, Bargaining, Depression, Acceptance, Anxiety

These emotional stages are considered ‘normal’ and an understandable coping mechanism. As with grieving, if they are prolonged, dominant and impact your social and occupational functioning, they are considered abnormal and require intervention. Remaining angry, resentful and depressed for decades will negatively impact your functioning.

Anxiety and depression in MS

Anxiety affects people with MS with a frequency often matching or exceeding that of depression. The highest prevalence of anxiety is observed in people with MS with low physical disability, defined by an Expanded Disability Status Scale (EDSS) score of less than 3.0. This finding suggests that anxiety is driven less by accumulated physical deficit than by the psychological factors of worry, fear and the inherent unpredictability of MS.

Maladaptive coping strategies are strongly associated with an increased risk of developing mood symptoms. A tendency to use avoidance coping – disengaging from problems rather than confronting them – is a significant predictor of poorer psychological outcomes. Similarly, psychological traits such as low optimism or a less positive attitude can heighten the risk of anxiety.

For a significant subset of patients, MS may first present not to a neurologist, but to a primary care physician, a therapist or a psychiatrist, with symptoms of anxiety or depression. Because the symptoms are psychiatric, the underlying neurological cause is not yet suspected.

Quality of life and daily functioning

Anxiety is a major contributor to the overall disease burden of MS, affecting nearly every aspect of life. Studies show that anxiety, often combined with depression, is linked to a poorer quality of life, cognitive dysfunction, increased risk of suicide, and significant occupational and social problems.

The impact of anxiety on many of the most challenging symptoms of MS – notably fatigue, pain and sleep problems – may be greater even than the effect of depression. MS symptoms can trigger or worsen anxiety, and the resulting anxiety intensifies the perception and severity of those same symptoms, thus creating a negative feedback loop.

Damaging health behaviours linked to undiagnosed and untreated anxiety can further compromise a patient’s well-being. For example, alcohol and substance abuse, as well as smoking, not only have their own intrinsic health risks but can also interfere with MS management and adherence to treatment.

Anxiety as a reaction to living with MS

The direct impact of the disease on the brain’s emotional circuits occurs in parallel with the profound psychological and existential challenges of living with MS. Even in the absence of any direct neurological damage to mood-regulating centres, the lived experience of MS itself provides rationale for the development of severe anxiety.

The unpredictability of the disease and the constant knowledge that a relapse could occur at any time, potentially worsening MS symptoms and existing function, create a state of chronic hypervigilance and worry. This pervasive sense of a loss of control over one’s own body and life is a catalyst for anxiety. Anxiety creates a vicious, self-perpetuating cycle where the physical and psychiatric symptoms mutually reinforce one another.

Multiple stressors

Beyond this overarching uncertainty, living with MS entails a host of stressors.

Diagnosis. The diagnostic journey is a period of intense anxiety, often involving a prolonged period of uncertainty as symptoms are investigated.Once diagnosed, patients face a continuous process of adjusting and readjusting to changing abilities.
Hidden problems. The invisibility of some of the most burdensome symptoms, such as debilitating fatigue, cognitive fog, or sensory disturbances, can lead to a profound sense of feeling misunderstood, isolated and frustrated.
Visible symptoms. Conversely, the emergence of visible symptoms, like a limp or the need for a mobility aid, can bring its own anxieties related to stigma and self-image.
Daily life. Financial concerns related to healthcare costs, employment and the ability to continue working, as well as the impact of MS on relationships and potential parenting, may further increase anxiety.

Existential threat

Profound existential and symbolic threats to a person’s sense of self can further exacerbate anxiety. The sense of loss triggered by a diagnosis of MS – loss of a healthy body, a previously held future and a former identity – is followed by changes in fundamental life roles. This can lead to feelings of inadequacy, guilt and a crisis of identity – perceived as a threat to one’s core self.The constant need to adapt to new limitations can feel like a continuous erosion of the self, and the fear of future disability becomes a fear of further loss of identity.

Addressing this existential dimension of anxiety is crucial for promoting long-term psychological adjustment and overall well-being. Treatment often involves helping individuals grieve their losses, redefine their sense of self and purpose within the context of their illness, and find new sources of meaning and value in their lives.

Cognitive impairment

The impact of anxiety on cognitive function is well documented. Cognitive impairment, particularly slowed information processing speed, is a common and debilitating feature of MS. Anxiety has a detrimental effect on cognitive domains that are already compromised, such as attention and executive functions. It does this by increasing an individual’s awareness of task-irrelevant, often threat-related, stimuli, which interferes with the goal-oriented cognitive processing required for the task at hand. Thus, the underlying cognitive deficit from MS is compounded by the cognitive interference from anxiety, leading to a greater overall level of impairment than either condition would cause alone. Importantly, therefore, treating a patient’s anxiety can lead to measurable improvements in their cognitive functioning.

Mood, fatigue, pain and sleep – a vicious cycle

Emotional problems rarely occur in isolation in MS; they are typically part of a clinical syndrome including fatigue, pain and poor sleep. This interconnected symptom cluster reduces health-related quality of life and establishes significant barriers to therapy and lifestyle modification.

Fatigue

Fatigue is one of the most common and disabling symptoms of MS, and it is strongly and consistently correlated with anxiety. This is not a simple correlation but a predictive relationship. Higher levels of anxiety at one point in time can predict the severity of fatigue at a later date. Conversely, higher levels of fatigue can predict the later development or worsening of anxiety.

The severity of depression in highly fatigued people with MS also makes the management of fatigue a high priority in reducing the overall psychiatric burden and allowing patients to engage in psychological interventions such as cognitive behavioural therapy (CBT).

Pain and emotional distress

A two-way relationship also exists between pain and anxiety, where anxiety is associated with higher reported pain intensity and greater interference of pain with daily activities. The pain symptoms cause distress and anxiety, and the physical and mental state of anxiety (e.g. muscle tension, worry, poor sleep) in turn exacerbates the symptoms. Moderate or severe intensity pain that interferes with work, household activities or enjoyment of life affects about one-third of people with MS.

Sleep

Sleep is probably the most neglected MS-related problem in routine clinical practice; most people with MS have a sleep disorder. Depression, anxiety, pain and many other MS-related symptoms affect sleep quality. Therefore, it is challenging to manage MS-related emotional disorders without addressing sleep quality.

Lifestyle management and adherence

The cyclical nature of this grouping of mood disorder, fatigue, pain and poor sleep creates barriers to effective management. Emotional distress and physical symptoms can hamper efforts to start or maintain a healthy lifestyle.Since modifiable lifestyle factors (e.g. exercise) are associated with reduced pain burden, a vicious cycle is established: the disease causes emotional distress, the emotional distress prevents adherence to healthy behaviours, and the lack of healthy behaviours exacerbates physical symptoms.

Inappropriate laughing and crying

Inappropriate laughing and crying (pseudobulbar affect, PBA) are two neglected symptoms that often go undetected and untreated in people with MS. This doesn’t have to be the case. They are a further sign of significant damage to the brain and yet another reason to diagnose and treat MS early and effectively.

Case study

When I first met her, she was in her early fifties. She had had MS for over 20 years. Her family now kept her at home, isolated from the wider world. Her behaviour would embarrass them. Why?

She suffered from pathological laughter and occasionally inappropriate crying; her husband and children could not deal with this in public. She was clearly very disabled when I met her; she was unsteady on her feet and had slurred speech and dancing eyes from cerebellar problems. She had gross cognitive impairment. When I introduced myself to her, she burst into tears. Within 2−3 months of starting sertraline, a selective serotonin reuptake inhibitor (SSRI), her husband informed me that her laughing and crying episodes had improved by over 50% and the family were now taking her out regularly. He was very grateful that I had been able to educate them about her symptoms and, more importantly, help her and them as a family deal with this problem.

PBA is diagnosed using standardised scales or questionnaires, which can be self-administered (Center for Neurologic Study-Lability Scale [CNS-LS]). These symptoms respond to tricyclic and SSRI antidepressants and to a combination pill (Nuedexta®; licensed in the USA) that includes dextromethorphan hydrobromide and quinidine sulfate.

Management of emotional disorders

Routine screening, targeted drug treatment and structured psychological and behavioural therapies are core components of integrated care in MS. Emotional changes in MS require treatment, just as physical symptoms do.

Screening and education

Routine screening for both anxiety and depression should be part of standard MS care and should be conducted at all scheduled neurological visits. You may be asked to complete different screening questionnaires for depression, anxiety, fatigue and poor sleep. Ideally these should be done before your appointment so that the healthcare professional (HCP) can act on them during the consultation.

HCPs should educate their patients and their families about potential emotional changes associated with MS, in particular, irritability, crying and mood swings. This education should help reduce the stigma and embarrassment associated with emotional outbursts and enable the patient’s support network to develop coping strategies.

Drug treatment

Drug treatment must be tailored to the specific diagnosis and emotional disorder.

Depression and anxiety: The standard use of selective serotonin reuptake inhibitors (SSRIs) and serotonin−norepinephrine reuptake inhibitors (SNRIs) is recommended for the management of clinical depression and anxiety disorders.
Irritability: Treatment options for irritability include SSRI antidepressants, which are often needed in addition to CBT.
Pseudobulbar affect (PBA): Low-dose tricyclic or SSRI antidepressants can be effective in the treatment of PBA, but their use is off-label. In the USA, the combination of dextromethorphan hydrobromide and quinidine sulfate has been approved for PBA. In other countries, the combination of these two drugs can be effective in PBA, but again, the use of these two drugs separately is off-label and not recommended.
Apathy: Therapeutic strategies, such as cognitive rehabilitation, that enhance cognitive processing speed and executive function are more appropriate for apathy than antidepressants. However, such approaches are hard to access on the UK NHS and are not available in many healthcare systems. There are no licensed medications for apathy, but anecdotal evidence suggests that fampridine and some stimulants may help.
Further research: Properly randomised controlled trials are needed to determine the effectiveness of drugs that some patients obtain and use without a prescription. These include cannabis, psychedelics and ketamine, which are currently not licensed for managing anxiety in MS and are not advised.

Psychological and behavioural interventions

Evidence-based structured psychological interventions are as important as drug treatment for the management of anxiety and depression and should be considered a first-line approach in MS. CBT can address maladaptive thought patterns (e.g. catastrophic thinking about the future) and avoidant behaviours common in anxiety. Acceptance and commitment therapy (ACT) focuses on promoting psychological flexibility and acceptance, which is crucial for managing the reactive distress, grief and fear stemming from the unpredictable nature of the disease. Mindfulness, relaxation techniques and structured exercise programs have also been shown to manage anxiety and stress effectively.

Interventions such as physical activity and social therapies enable some people with MS to process the grief and losses imposed by MS. Simple behavioural strategies, such as taking a break from a conversation when emotions escalate, can also be beneficial.

Protective factors

Several protective factors can bolster resilience and lower the risk of anxiety. Motivational coping styles that involve direct problem-solving and active participation in treatment planning (i.e. self-management) are associated with better adjustment.One of the most critical protective factors is the presence of social support. Robust practical and emotional help from friends and family, and the knowledge that help is available if needed, significantly reduces the risk of mood symptoms.Finding ways to continue participating in previously enjoyed activities, albeit with new limitations, are key to coping. Interventions aimed at strengthening coping skills, fostering optimism and building social support networks can play a crucial role in preventing and treating anxiety in this population.

The therapeutic challenge

There is substantial symptom overlap between anxiety and depression (e.g. sleep disturbance, fatigue, difficulty concentrating) and between these mood disorders and the primary symptoms of MS.This can make it challenging for HCPs to discern whether a specific symptom, e.g. fatigue, is primarily a neurological symptom of MS, a physical symptom of depression, a consequence of the hyperarousal and poor sleep of anxiety, or a combination of all three. Use of appropriate screening tools can help to ensure that both anxiety and depression are accurately identified and appropriately treated.

Conclusion

MS profoundly affects emotional health across a broad and complex spectrum, manifesting as major depressive disorders, high levels of anxiety, the neurological syndrome of pseudobulbar affect, the cognitive−behavioural syndrome of apathy and, rarely, mania. These emotional changes are driven by primary damage to cortical-subcortical and brainstem circuits, coupled with reactive psychological distress resulting from living with a chronic, unpredictable illness. The current standard of care mandates routine screening, targeted drug treatments and psychological support utilising CBT and ACT.

Bladder and bowel, Intimate issues

Intimate issues: bladder dysfunction

21/07/2025 Gavin Giovannoni

Bladder dysfunction in people with MS is a sign of early damage, particularly to the spinal cord, and an early indication of a poor prognosis. Why do people with MS who develop bladder dysfunction do worse than those with no bladder symptoms? Here, I explain why I take bladder problems seriously and their implications for MS management.

Key points

Urinary hesitancy, urgency, frequency and incontinence, including at night, are bladder problems that affect many people with MS and cause significant frustration and anxiety.
A range of drug-based treatments, behavioural techniques and specialist physical interventions can help people with MS to manage bladder dysfunction and achieve adequate control.
However, the bladder pathways will probably continue to be affected in the long term due to the development of new lesions or the expansion of old lesions.
Frequent and severe urinary tract infections (UTIs) increase the likelihood that MS will progress.
I recommend regular dipstick testing at home, as part of your MS self-management, to increase the chances of early detection and treatment of a UTI.
Lifestyle approaches, such as avoiding smoking and reducing alcohol and caffeine consumption, should help to reduce bladder symptoms. Pelvic floor exercises are also important.
Dehydration is not a good way to control your bladder symptoms. Chronic dehydration can have a significant impact on your overall health and well-being and can exacerbate many of your MS symptoms.

Causes and significance of bladder dysfunction

Bladder dysfunction is the most common symptomatic problem I encounter in an MS clinic, affecting more than 50% of people with MS. It is one of the signs of early damage, particularly spinal cord damage, and an early indication of a poor prognosis. It therefore has important implications for treatment: if you have early bladder symptoms, you may want to take a more effective therapy early on rather than starting on a less effective DMT and waiting to see how you respond. It is best to maximise your chances of responding to treatment by opting for a highly efficacious therapy first-line. I call this ‘flipping the pyramid’.

Infections, both viral and bacterial, are a known trigger of relapse in MS. Frequent and severe urinary tract infections (UTIs) increase the likelihood that your MS will progress. This is why it is important to improve the management of bladder problems in people with MS to prevent or reduce UTIs. You can read more about managing UTIs here.

Why do people with MS who develop bladder dysfunction do worse than those with no bladder symptoms? The bladder is a complicated organ with several neurological components that need to be coordinated. The descending nerve fibres that travel from the brain to the lower segments of the spinal cord are very long and have the greatest chance of being damaged by MS lesions in their path down to the bladder centre in the sacral area of the lower spinal cord. Therefore, any progressive or worsening MS damage is likely to manifest with bladder dysfunction early on.

The detrusor (or balloon) muscles and the sphincter (or valve) need to coordinate their action to enable normal bladder function. When the bladder is filling, the detrusor muscle relaxes to allow the bladder to expand and the sphincter contracts to keep the urine in the bladder. The opposite occurs when you pass urine; the sphincter opens and the detrusor contracts to empty the bladder.

Common MS-related bladder problems

Hesitancy

Urinary hesitancy occurs when the function of the detrusor and sphincter muscles is not coordinated: you try to pass urine, but the bladder sphincter won’t open. Hesitancy may be intermittent; if you try again later, the bladder will open, allowing you to pass urine. Conversely, the sphincter may close as you pass urine, which breaks up the urine stream or prevents complete bladder emptying; this can cause dribbling. The medical term for incoordination of the bladder muscles is dyssynergia or, more correctly, detrusor-sphincter-dyssynergia (DSD). People with MS find urinary hesitancy and its unpredictability very frustrating.

The drug treatment for DSD includes alpha-blockers (prazosin, indoramin, tamsulosin, alfuzosin, doxazosin and terazosin). Other strategies include small bladder stimulators or vibrators that are placed over the pubic area and work by blocking signals that inhibit the sphincters. The vibrators work in some people with MS and may help relax the sphincter.

Trying to relax when passing urine can help to improve hesitancy. The sound of running water, for example from a tap, may trigger the relaxation of the sphincter. Simulating this in public toilets may not be possible. Some people with MS find pressing on the lower abdomen helps. If all else fails, intermittent self-catheterisation (ISC) may be the only option to manage urinary hesitancy (see below).

Frequency and urgency

In MS the commonest bladder problem is spasticity, or irritability, of the detrusor muscle. The detrusor can’t relax, which prevents the bladder from filling to its maximum capacity. Frequent spasms of the detrusor muscle tell the brain that the bladder is full and you need to pass urine. This causes frequency, i.e. the need to use the toilet many times during the day and night. Frequency often accompanies the symptom of urgency, the need to get to the toilet as quickly as possible to prevent incontinence.

When urgency is a problem, distraction techniques such as breathing exercises and mental tricks (e.g. counting) may be helpful. If urinary frequency is your main problem, you might try to retrain your bladder by holding on for as long as you can each time before passing urine. The aim is to train the detrusor muscle to expand more to hold on for longer when you need the toilet. These behavioural techniques rarely work for long; MS is a relapsing and/or progressive disease, and the bladder pathways will likely continue to be affected due to the development of new lesions or the expansion of old lesions.

Incontinence

Incontinence occurs when you lose the ability to suppress or ignore the signals from the detrusor muscle with the result that the sphincter relaxes or opens as part of a spinal cord reflex. We typically treat this problem with anticholinergic drugs, e.g. oxybutynin, solifenacin or tolterodine. The older generation anticholinergics such as oxybutynin cross the blood ̶ brain barrier and enter the brain, where they can exacerbate cognitive problems in people with MS. The commonest side effect of anticholinergics is dryness of the mouth; they can also worsen constipation. People with MS must be warned about the risk that anticholinergics will relax the bladder too much and precipitate urinary retention; the solution to urinary retention is ISC.

The good news is that we now have a relatively new muscle relaxant, mirabegron (Betmiga), which activates the β3 adrenergic receptor in the detrusor muscle. I am increasingly using mirabegron to avoid the side effects (particularly cognitive issues) associated with anticholinergics. The main side effect of mirabegron is that it tends to increase your blood pressure.

Nocturia

Nocturia means you need to get up frequently at night to pass urine. If nocturia is your main bladder problem, using agents to concentrate the urine at night might help. A hormone called DDAVP works on the kidneys to reduce urine production; it is available as a nasal spray or tablets (Desmotabs or Desmospray). DDAVP should only be taken once a day, to avoid continuous water retention by the kidneys; this presents as swelling of the feet and reduces the salt or sodium levels in your blood, which can be dangerous. You therefore need to have your sodium levels checked about 4 ̶ 6 weeks after starting DDAVP therapy.

Second-line treatments for bladder problems

If you fail to respond to anticholinergics, mirabegron and/or behavioural techniques, you need a bladder scan to see if you have a raised residual volume (the amount of urine left after you have emptied your bladder). If the residual volume is greater than 80 ̶ 100mL you may need to consider intermittent self-catheterisation (ISC). Some continence advisors act at the 80 mL threshold, and others at the 100 mL threshold, when recommending ISC.

Intermittent self-catheterisation

ISC serves two purposes. It increases your functional residual bladder volume, allowing more storage space for urine, which reduces frequency and urgency. This can help if you need to travel some distance or to join in a social activity without having to pass urine. It also helps to reduce nocturia, which in turn improves sleep and possibly MS-related daytime fatigue.

ISC also removes urine from the bladder. The residual urine acts as a culture medium for bacteria; by clearing your bladder you can prevent bladder infections. Conversely, if you don’t do the ISC technique correctly you can introduce bacteria into the bladder that then cause infections.

Botox

Botox injection into the detrusor muscle is increasingly used as a treatment for bladder dysfunction, in conjunction with ISC. Botox paralyses the muscle, turning it into a flaccid bag for urine storage. The surgical techniques that were previously used to remove the nerve supply to the bladder (which had the same effect as Botox) are now rarely used.

Percutaneous tibial nerve stimulation

Percutaneous (or posterior) tibial nerve stimulation is a form of neuromodulation that can help with impaired bladder function and may improve urinary urgency, urinary frequency and urge incontinence. It is offered as a treatment in specialist neuro-urology units.

Permanent catheterisation

If all else fails, some people with MS may need to be permanently catheterised. This can be done via the urethra or the lower abdominal wall; the latter is called a suprapubic catheter. Being permanently catheterised sounds drastic, but this significantly improves the quality of life in some people with MS. Allowing bladder dysfunction to control your life can result in social isolation and constant anxiety about being incontinent in public. With the above-mentioned strategies, adequate bladder control should be the norm in MS.

In my experience, the biggest hurdle to achieving adequate bladder control is when people with MS assume their bladder symptoms are part of the disease and resign themselves to living with them. Such patients may start using continence pads as if this is normal or inevitable for someone living with MS. This is not normal; incontinence can lead to skin rashes and pressure sores. Please don’t accept this as the norm or something you must live with. If you have problems, tell your MS nurse or neurologist; they can help you.

Lifestyle factors that impact your bladder

Smoking, alcohol and caffeine

Nicotine irritates the bladder. If you are a smoker, then stopping smoking may significantly improve your bladder symptoms. Similarly, reducing alcohol and caffeine consumption may help; these agents are diuretics and cause the kidneys to make more urine.

Pelvic floor exercises

One of the treatments recommended to all patients with bladder problems is pelvic floor exercises. These are also important for managing bowel and/or sexual problems. For detailed guidance on incorporating these into your daily life, please see pelvic floor training post.

Avoiding dehydration

Try to anticipate times when urinary frequency and urgency will be most inconvenient; reducing the amount you drink beforehand may help. For example, don’t drink too much for 2 ̶ 3 hours before you go out. After you have finished passing urine, go back to the toilet again after a few minutes to try to pass some more urine. This is called the double micturition technique, which aims to ensure the bladder is emptied completely. However, do not reduce your total fluid intake to less than 1.5 litres each day.

Dehydration is not a good way to control your bladder symptoms. The issue of people with MS dehydrating themselves to manage their bladder problems was highlighted as early as the 1960s by Professor Bryan Matthews, a neurologist in Oxford, in his textbook on MS.

When researching the topic in the 1990s, it became clear to me that people with MS with severe disability were most likely to have bladder dysfunction and were chronically dehydrating themselves to manage urinary frequency, urgency and nocturia. Studies showed that a high urinary concentration of creatinine, a waste product that the kidneys filter out of the blood through the urine, correlated with increased disability levels. Urine containing myelin basic protein-like material (MBPLM), an indicator of myelin damage in MS, was also shown to correlate with disability. It is dehydration that causes higher levels of MBPLM and creatinine in the urine, indicating that dehydration is associated with disability.¹

A more recent paper from researchers in the Southampton group described the same findings, that urinary tract symptoms are very common in people with progressive MS and are associated with inadequate hydration.²

Despite highlighting the issue of chronic dehydration in MS over the years, it remains a persistent problem. My message is clear: don’t use dehydration to manage your bladder symptoms. Chronic dehydration can have a significant impact on your overall health and well-being and can exacerbate many of your MS symptoms. Some potential effects of chronic dehydration are listed in the box below.

Physical performance: Dehydration can decrease physical endurance, cause muscle cramps and exacerbate or cause fatigue. This can affect overall physical performance and make everyday tasks more challenging.
Cognitive function: Dehydration has been linked to cognitive impairment, including issues with concentration, alertness and short-term memory. Prolonged dehydration may even contribute to long-term cognitive decline.
Mood and mental health: Studies have shown that dehydration can affect mood and contribute to increased feelings of anxiety and irritability. In severe cases, it can even lead to symptoms resembling depression.
Kidney function: Chronic dehydration can put a strain on the kidneys, potentially leading to the formation of kidney stones and urinary tract infections. It can impair the kidneys’ ability to effectively filter waste from the blood. It also makes you more susceptible to the side effects of non-steroidal anti-inflammatory medications.
Digestive problems: Dehydration can lead to constipation and other digestive issues. It may also contribute to an increased risk of developing peptic ulcers and acid reflux.
Skin health: Inadequate hydration can lead to dry, flaky skin and exacerbate conditions such as eczema and psoriasis. Proper hydration is essential for maintaining overall skin health and elasticity.
Heat-related illnesses: Dehydration reduces your body’s ability to regulate temperature, increasing the risk of heat exhaustion and heat stroke, particularly in hot and humid conditions. Please remember that people with MS, particularly those with more advanced MS, may already have a problem with thermoregulation.

In conclusion

I advise using a holistic approach to managing urinary symptoms, in addition to medication or other aids where recommended. Please review the questions below to check whether you are optimising your self-management.

Have you deconditioned your bladder because you are not training yourself to resist emptying it whenever you get the urge to pass urine? The bladder is a muscle that needs to be trained.
Have you tried peripherally acting anticholinergics or mirabegron?
Have you had a post-micturition bladder scan to see if you are emptying your bladder?
Do you need to use intermittent self-catheterisation to increase your functional bladder volume?
Do you have a chronic low-grade urinary tract infection? Are you performing regular urine dipstick testing (see post on UTIs and dipstick testing)?
Do you have bladder stones?
Have you tried DDAVP (Desmotabs or Desmospray) to help concentrate your urine without dehydrating yourself?
Are you avoiding bladder irritants or stimulants such as caffeine and nicotine?
Are you doing your pelvic floor exercises? If you are a post-menopausal woman, have you tried HRT (hormone replacement therapy)? Pelvic floor tone and bladder function often improve on HRT.

Bladder and bowel

Pelvic floor training

13/07/2025 Gavin Giovannoni

Do you have bowel, bladder and/or sexual problems? Here, I discuss pelvic floor exercises, which may help alleviate all these symptoms.

Pelvic floor exercises are one of the treatments recommended for all patients with bladder problems.¹ However, when I ask patients if their continence advisors have formally instructed them on how to do these exercises, most say they were given an instruction sheet, referred to the pelvic floor exercise NHS site or other online resources. What is clear is that few people have been adhering to the pelvic floor exercise regimen; I estimate this to be less than 20% or even 10% of patients.

Who should do pelvic floor exercises?
Do you know how to do them and at what intensity?
Have you adhered to doing them?

Pelvic floor structure and function

The pelvic floor consists of muscles and other tissues at the bottom of the pelvis. The muscles attach to the pelvic bones and sacrum. The pelvic floor supports the lower abdominal organs and is essential for maintaining bowel, bladder and sexual function. The pelvic floor muscles have a constant tone at rest, i.e. they are tonically contracted. Voluntary and involuntary contraction and relaxation of the pelvic floor allow for normal bowel, bladder and sexual function; for example, reflex muscle contraction in response to sudden increases in intra-abdominal pressure, such as coughing or sneezing, maintains continence. Pelvic floor dysfunction causes symptoms such as urinary incontinence, voiding difficulty, pelvic organ prolapse, anal incontinence, evacuation difficulty, sexual dysfunction and pain.

Pelvic floor muscle training

Like all muscle training programmes, pelvic floor muscle training (PFMT) is designed to improve pelvic floor muscle strength, endurance, power, relaxation or a combination of these. PFMT is typically unsupervised and self-administered. On the NHS, PFMT can be supervised by an HCP, typically a physiotherapist or a continence nurse. The National Institute for Health and Care Excellence (NICE), recommends PFMT to manage symptoms of pelvic floor dysfunction in women. NICE also recommends encouraging all women aged 12 and over to perform preventive exercises. This makes sense; the pelvic floor is just another muscle, and strengthening it should help prevent pelvic floor dysfunction in the future. Therefore, I have added PFMT to my list of exercises for my MS prehabilitation programme.

PFMT is indicated mainly for urinary incontinence, pelvic organ prolapse and faecal incontinence. These are all problems associated with MS; in many cases MS either causes or contributes to these symptoms.

PFMT for women

A self-administered programme should include basic voluntary contractions, which aim to improve pelvic floor muscle reaction to activities such as coughing, sneezing, exercise, and lifting, as well as sustained voluntary contractions that enhance endurance.

Sit comfortably with your knees slightly apart and contract the pelvic floor by lifting and tightening the muscles around the anus and vagina—as if to prevent the passage of gas and stop your urine flow.
Once you can achieve PFMT seated, you can perform the exercises in a standing position and during activity.
If you experience stress urinary incontinence (e.g. when sneezing), you can contract the pelvic floor in preparation for a leakage-provoking event; this is called the “knack”.
A basic voluntary contraction involves a hold of 1 ̶ 2 seconds, with the same rest time; a sustained voluntary contraction should last for 6 ̶ 10 seconds, with the same rest time. Once you establish a baseline sustained contraction, gradually increase the length of the contraction (to a maximum of 10 seconds).

Approximately one-quarter of women cannot perform a pelvic floor contraction on their first attempt with just verbal instruction. Digital assessment of the pelvic floor – using biofeedback devices, electrical stimulation, or vaginal cones – is therefore useful to help them know when they are contracting effectively. If your progress is minimal, please ask your MS team for a referral to a suitable HCP for clinical assessment and a personalised, supervised PFMT programme.

Other resources providing useful instructions are available, e.g. a patient education leaflet from the International Urogynecological Association and smartphone applications such as the Squeezy NHS pelvic floor app.

PFMT for men

Pelvic floor dysfunction can also occur in men, and PFMT is a recommended first-line conservative treatment. The following is an extract from the Pelvic Obstetric & Gynaecology Physiotherapy ‘Pelvic floor muscle exercises and advice for men’.

Sit comfortably with your thighs, buttocks and tummy relaxed. Squeeze and lift the muscles from the front by either imagining you are trying to stop yourself from passing urine or trying to shorten or draw your penis up and inwards. Now try lifting the muscles from the back as if stopping the escape of wind. When you feel you have the hang of it, try lifting the front and back together. Don’t worry if you find it too difficult; after some practice, you will find the easiest and most comfortable method. This is a pelvic floor muscle contraction. To check that your pelvic floor muscles are working correctly:

Place your fingers on your perineum. You should feel the perineum lift upwards as you contract your muscles.
Stand in front of a mirror; when you do a pelvic floor muscle contraction, you should see the base of your penis draw inwards and your testicles/ scrotum lift.

Try not to hold your breath while you contract your pelvic floor. You are more likely to breathe easily if you lift your pelvic floor on your out-breath. Do not actively clench your buttocks, but don’t be concerned if you simultaneously feel a tightening in your buttocks and/or lower abdomen. This is normal. If you cannot feel a definite tightening in the pelvic floor muscles, you should seek professional advice.

Fatigue and insomnia, Sleep disorders

Understanding and managing insomnia in MS

26/03/2025 Gavin Giovannoni

Insomnia is the most common sleep disorder I encounter in my MS practice. It often goes untreated because people with MS accept it as part of living with the disease or because healthcare professionals (HCPs) prioritise other MS-related problems.

Key points

Insomnia is more common in people with MS than in the general population and is associated with poor mental health and other medical problems.
Factors that contribute to insomnia include anxiety, frequent visits to the bathroom, pain, leg spasms, restless legs, inability to roll over in bed, menopausal symptoms (hot flushes and night sweats) and poor sleep hygiene; they need to be managed appropriately.
Several online tools and questionnaires exist that can help you assess the nature and severity of insomnia.
Sleep aids (drugs) available over the counter or on prescription may be helpful.
Cognitive and digital approaches to insomnia management also have a role but are not widely available or suitable for everyone.
Complementary and alternative therapies are a valuable aid to self-management of insomnia.

Sleep, glorious sleep!

Sleep is the most essential performance-enhancing agent we know. You know what it is like if you wake in the morning and have had a good night’s sleep; you feel energised, your mood is good and you are ready to face the day. In contrast, when you wake from a night of tossing and turning, or not being able to turn, legs jerking, getting up several times to go to the toilet, maybe with a hangover from too much alcohol the night before, then you are irritable, your mood is low and it is challenging to get through the day.

Most studies on sleep in MS show that over 70% of people with MS have a sleep disorder. In an MS-Selfie survey on sleep, a minority (33%) of 173 respondents described their sleep as good, very good or excellent, with 49% formally diagnosed with one or more sleep disorder and over 80% not having undergone formal sleep studies. Insomnia is the most common sleep disorder I encounter in my MS practice. Insomnia is defined as difficulty initiating or maintaining sleep, which can be a symptom or a disorder. If a disorder, insomnia is associated with a feeling of distress about poor sleep, and it disrupts social or occupational functioning.

Causes and impact of insomnia

In the general population, ~10% of adults have insomnia disorder and another 15 ̶ 20% report occasional insomnia, i.e. the symptom. In comparison, 40 ̶ 50% of people with MS have insomnia. Insomnia is more common in women than in men and is associated with poor mental health and other medical problems. Common MS-associated symptoms linked to insomnia (and resulting in fatigue) include pain, lack of bladder control, spasticity, restless legs, periodic limb movements and discomfort from being unable to turn in bed; other factors that contribute to insomnia – not just in people with MS but also more widely – include alcohol and stimulant misuse, menopausal symptoms, poor sleep hygiene (daytime napping), deconditioning (lack of exercise), anxiety and depression. All these problems can interfere with sleep initiation, maintenance or perception in people with MS.

Insomnia can be episodic (with symptoms lasting 1 ̶ 3 months) or situational (of short duration, in response to a specific event of circumstance) and tends to follow a persistent course. Episodic insomnia refers to insomnia for a defined period, for example lasting several months linked to anxiety. In comparison, situational insomnia refers to insomnia triggered by a specific stimulus or event, such as sleeping away from home or after alcohol consumption. Chronic insomnia can cause depression and is associated in the general population with the development of hypertension and dementia. Insomnia assessment, diagnosis and management require a careful history to document its course, concomitant comorbidities and potential contributing factors.

Several studies show that approximately 40% of people with MS have obstructive sleep apnoea and that it is not necessarily associated with obesity and a large neck. Sleep apnoea in MS may be due to brain stem pathology from MS affecting pharyngeal (throat) muscle function. If you know or think you are a snorer and you have periods when you stop breathing, you can download one of the many smartphone sleep apps that can assess this.

Approaches to managing insomnia

Any MS-related symptoms that can affect sleep need to be managed appropriately. How can you treat insomnia if your sleep is interrupted by anxiety-related rumination, nocturia, pain, leg spasms, restless legs, inability to roll over in bed, menopausal symptoms of hot flushes and night sweats and poor sleep hygiene?

Recording your sleep patterns

A 24-hour history of sleep ̶ wake behaviours can help to identify additional behavioural and environmental factors for intervention. Patient-reported outcome measures (PROMS) and sleep diaries provide valuable information about the nature and severity of insomnia. They can help screen for other sleep disorders and monitor treatment progress.

A sleep diary should collect information on your sleep cycle (bedtime, arising time, napping) and estimates of your sleep ̶ wake characteristics, i.e. sleep latency (how long it takes to fall asleep), number and duration of awakenings, and an estimated overall sleep time. Useful PROMS include the Insomnia Severity Index, the Pittsburgh Sleep Quality Index, the STOP-BANG Sleep Apnea Questionnaire (for evaluating the risk of sleep apnoea) and the Restless Legs Syndrome Rating Scale.

Sleep hygiene

I suggest you start with a simple self-help guide to improve your sleep hygiene.

Ensure you spend an appropriate amount of time asleep, at least 6 hours in bed. Some people need more than this to feel refreshed.
Limit daytime naps to 30 minutes. Please note that napping does not make up for inadequate nighttime sleep.
Avoid stimulants such as caffeine, modafinil and nicotine close to bedtime.
Only drink alcohol in moderation. Alcohol is known to help you fall asleep faster, but too much disrupts sleep.
Exercise helps improve sleep quality. As little as 10 minutes of aerobic exercise daily can enhance the quality of sleep.
Don’t eat before going to bed. Heavy foods and fizzy drinks can trigger indigestion or heartburn/reflux that disrupts sleep.
Ensure you get adequate exposure to natural light; exposure to sunlight during the day and darkness at night help to maintain a regular sleep ̶ wake cycle.
Establish a regular relaxing bedtime routine, which helps the body recognise it is bedtime. This could include taking a shower or bath or reading. However, avoid reading or watching emotionally upsetting content before attempting to sleep.
Make sure that your sleep environment is pleasant. Your mattress and pillows should be comfortable. The bedroom should be cool for optimal sleep (16 ̶ 20°C). The bright light from lamps, smartphones and television screens can make it difficult to fall asleep, so turn those lights off or adjust them when possible. Use the blue filter mode on your smartphone and other devices to reduce the inhibition of melatonin from light. Consider using blackout curtains, eyeshades, earplugs, white noise machines and other devices to make the bedroom more relaxing.
If you have pain, nocturia, restless legs, sleep apnoea or other causes of discomfort, get these adequately managed via your HCP.

If these self-help measures fail, other current treatment options include prescription-only and over-the-counter (OTC) medications, cognitive behavioural therapy for insomnia (CBTI) and complementary and alternative therapies.

Over-the-counter sleep aids

Over-the-counter sedatives tend to be first-generation antihistamines with potent centrally acting anticholinergic effects that impair cognitive function and long-term brain health. I recommend you avoid them (see newsletter entitled ‘Your anticholinergic burden’).

Some people with MS self-medicate with OTC melatonin, cannabidiol (CBD) or tetrahydrocannabinol (THC) preparations. Melatonin has a U-shaped dose ̶ response curve for some individuals; therefore, lower doses may be better than higher doses. In general, I cannot recommend the use of CBD or THC for insomnia. CBD is a drug and is associated with liver toxicity; it may also interact with your other medications. However, if you do decide to buy CBD and/or THC, please use a reputable supplier and pharmaceutical-grade products. Medicinal cannabis cannot be prescribed on the NHS but can be obtained via private clinics. Many patients purchase it online; as a doctor, I cannot recommend buying it this way.

Prescription-only sleep aids

If you raise the issue of insomnia with your HCP, they may reach for the prescription pad. Before accepting a sedative, please be aware of its limitations and ensure you have optimised all the above guidance. Sedatives are only a short-term solution; they work well for about 4 ̶ 5 days before you develop tachyphylaxis and need higher doses. Tachyphylaxis refers to the rapidly diminishing response to successive doses of a drug, rendering it less and less effective. Once you develop tachyphylaxis and stop taking sedatives, you may experience rebound insomnia. Benzodiazepines (e.g. diazepam) are addictive and doctors generally avoid prescribing them for insomnia. However, they still have a role when insomnia is part of acute anxiety. The sedatives most often used are the so-called Z-drugs (zolpidem, zopiclone, zaleplon and eszopiclone). Zopiclone and eszopiclone have a longer half-life than the other two drugs (5 ̶ 6 hours). In comparison, zolpidem and zaleplon act for a much shorter period (1 ̶ 3 hours).

The older, tricyclic antidepressants, such as amitriptyline, are commonly used as sedatives. I have largely stopped prescribing them unless there is another reason for using a tricyclic, e.g. to help with pain management (please read my newsletter ‘Amitriptyline: the neurologist‘s dirty little secret’. I mostly use duloxetine in my clinical practice for pain management. It is not as sedating as tricyclic antidepressants, but some patients find it helps with sleep. Duloxetine is a serotonin ̶ noradrenaline reuptake inhibitor and has fewer anticholinergic side effects than tricyclics.

Antispasticity agents such as baclofen and gabapentinoids (gabapentin and pregabalin) also help sleep, but they should only be used for insomnia if you have spasticity or, in the case of the gabapentinoids, spasticity and/or pain that needs to be managed.

Psychiatrists and some neurologists use sedating antipsychotics to help with insomnia. Sadly, as a neurologist, I have seen too many severe adverse events resulting from the liberal use of antipsychotics as sedatives. There needs to be a good reason for prescribing an antipsychotic, and insomnia in isolation is not one of them; however, there is a role for them in patients with cognitive issues or significant psychiatric problems. The older generation antipsychotics (e.g. haloperidol) have now been replaced by safer drugs such as quetiapine and olanzapine.

A new class of sedatives is now available in some countries; these are the dual orexin receptor antagonists suvorexant, lemborexant and daridorexant. Daridorexant is NICE approved for use by the NHS; it is recommended for treating insomnia in adults with symptoms lasting for 3 nights or more per week for at least 3 months and whose daytime functioning is considerably affected, but only if CBTI has been tried and not worked, or if CBTI is not available or is unsuitable.

Cognitive approaches to managing insomnia

Cognitive Behavioural Therapy for Insomnia (CBTI)

Only some patients receive CBTI, owing to a lack of adequately trained therapists. CBTI aims to change the behaviour and psychological factors that contribute to insomnia (e.g. anxieties and unhelpful beliefs about sleep). At the core of CBTI are behavioural and sleep-scheduling strategies (sleep restriction and stimulus control instructions), relaxation methods, psychological and/or cognitive interventions to change unhelpful beliefs or excessive worrying about insomnia, and sleep hygiene education.

CBTI is focused on sleep and oriented toward problem-solving. A psychologist typically guides the process over roughly six consultations. Several variants in the methods for implementing CBTI include shorter formats, group therapy, using other providers such as counsellors and specialist nurses, and the use of telehealth digital platforms, including smartphone applications.

Brief behavioural treatment for insomnia

This abbreviated version of CBTI emphasises behavioural components and is typically implemented in fewer sessions. It involves education about sleep regulation, factors that promote or interfere with sleep, and a tailored behavioural prescription based on stimulus control and sleep restriction therapy.

eCBTI

Digital CBTI (eCBTI) is becoming increasingly popular. The Sleepio application, which is recommended and covered by the NHS, has a positive effect on several sleep outcomes and is said to be as effective as medication. NICE recommends Sleepio as a cost-saving option for treating insomnia and insomnia symptoms in primary care for people who would otherwise be offered sleep hygiene or sleeping pills. A medical assessment should be done before referral to Sleepio for people who may be at higher risk of other sleep disorder conditions, such as during pregnancy or in people with comorbidities.

Complementary and alternative therapies

Sleep restriction

Limit the time you spend in bed to match your sleep time as closely as possible. After the initial restriction, the sleep window can be gradually adjusted upward or downward on a weekly basis as a function of sleep efficiency (time asleep÷time spent in bed×100) until an appropriate sleep duration is established.

Stimulus control

You need to follow a set of instructions designed to reinforce the association between bedtime and bedroom stimuli with sleep and to re-establish a consistent sleep ̶ wake schedule.

Go to bed only when you feel sleepy.
Get out of bed when you are unable to sleep.
Use the bed and bedroom for sleep and sex only; do not use your bed for reading, watching television, etc.
Try and get up at the same time every morning.
Avoid napping.

Relaxation training

Try using different procedures such as progressive muscle relaxation and imagery training to reduce arousal, muscle tension and intrusive thoughts that interfere with sleep. Relaxation procedures need to be practised daily over a few weeks.

Cognitive therapy

This is a psychological approach to revising many common misconceptions about sleep and reframing unhelpful beliefs about insomnia and its daytime consequences. This method also reduces excessive worrying about sleep difficulties and their daytime consequences. Additional cognitive strategies include paradoxical intention (willingly trying to stay awake rather than trying to fall asleep) to alleviate the performance anxiety triggered by attempting to force sleep.

Sleep hygiene education

These general guidelines include advice about a healthy diet, exercise, substance use, and optimising environmental factors such as light level, noise and excessive temperature that may promote or interfere with sleep (see above).

Acceptance and commitment therapy (ACT)

ACT is a form of psychotherapy that aims to educate people to stay focused on the present moment and accept life experiences, thoughts, and feelings (even negative ones) without trying to change them. ACT uses different methods and processes (e.g. acceptance, defusion, mindfulness, and committed action) to increase psychological flexibility.

Mindfulness

This meditation method involves observing one’s thoughts and feelings and letting go of the need to change or ruminate. Originally designed to reduce stress and anxiety, mindfulness has been adapted for the management of insomnia and can be included as one component of ACT.

Conclusion

Poor sleep, be it due to a comorbid sleep disorder, MS-related symptoms or poor sleep hygiene, is a very common problem in people with MS. It contributes to daytime fatigue and hypersomnolence and impacts physical and cognitive function. As a result, poor sleep reduces quality of life and can exacerbate other MS-related problems such as poor cognition, anxiety and depression. It is essential that poor sleep is documented, investigated appropriately and treated accordingly to improve the functioning and quality of life of people with MS.
