Multiple sclerosis (MS) is a cell-mediated autoimmune condition characterised by repeated episodes of inflammation of the nervous tissue in the brain and spinal cord, causing loss of the insulating myelin sheath.

Multiple areas of scar tissue (sclerosis) form along the neurons. This slows or blocks the transmission of signals to and from the brain and spinal cord. In this way movement and sensation may be impaired.

The causes of MS are not completely understood but the autoimmune process appears to be caused both by genetic and environmental factors - eg, viral infections in early life. Minor viral infections frequently precipitate relapses.

There are different patterns of MS:

  • Relapsing-remitting MS: symptoms come and go. Periods of good health or remission are followed by sudden symptoms or relapses (80% of people at onset).
  • Secondary progressive MS: follows on from relapsing-remitting MS. There are gradually more or worsening symptoms with fewer remissions (about 50% of those with relapsing-remitting MS develop secondary progressive MS during the first ten years of their illness).
  • Primary progressive MS: from the beginning, symptoms gradually develop and worsen over time (10-15% of people at onset).

Acute attacks are followed by periods of remission when there is remyelination but, with advancing disease, this process begins to fail and periods of remission are less frequent.

  • The global distribution of MS can be generalised as increasing with distance north or south of the equator but that summary conceals many places with disproportionately high or low frequencies. Caucasians have the highest risk.
  • The prevalence of MS recorded in the UK from 1990 to 2010 increased by about 2.4% per year, reaching 285.8 per 100 000 in women and 113.1 per 100 000 in men by 2010.
  • There was a consistent decrease in incidence of MS reaching 11.52 per 100,000/year in women and 4.84 per 100,000/year in men by 2010.
  • Peak incidence occurred between ages 40 and 50 years and maximum prevalence between ages 55 and 60 years.
  • Women accounted for 72% of prevalent and 71% of incident cases.
  • Scotland had the highest incidence and prevalence rates in the UK.

Risk factors

  • Family history - about 2% of people with a first-degree relative with MS will develop the condition.
  • There is no evidence that pregnancy influences the overall course of the condition over time. Women with MS who wish to become pregnant should be advised that the risk of relapse decreases during pregnancy and increases transiently postpartum.
  • There is no single specific diagnostic test available. The diagnosis can be made clinically (by a consultant neurologist) in most people and an MRI scan should not be used in isolation to make the diagnosis.[2] 
  • If there is doubt about the diagnosis, further investigation should be used to exclude an alternative diagnosis or find evidence that supports the diagnosis of MS.
  • Dissemination in space should be confirmed, if necessary, using an MRI scan, interpreted by a neuroradiologist, using agreed criteria - eg, the revised McDonald criteria:[3] 
    • Objective evidence of dissemination in time and space of lesions typical of MS is mandatory, as is the exclusion of other, better explanations for the clinical features.
    • Historical reports of symptoms may suggest previous episodes of demyelination but cannot be used without objective evidence to satisfy the requirement of lesions disseminated in time and space.
    • MS can be diagnosed on purely clinical evidence of lesions separated in time and space.
    • MRI and laboratory evidence are desirable and may be essential where clinical evidence is insufficient for a secure diagnosis.
    • The choice of investigation will be determined by the clinical situation - eg, a delayed visual evoked potential is of value in a person with a spinal cord lesion but is of little value in a person with optic neuritis.
    • MRI scanning is less useful in older people and in other inflammatory conditions - eg, acute encephalomyelitis where its specificity is lower.
  • Dissemination in space may also be confirmed using evoked potential studies; visual evoked potential studies should be the first choice.

There is a wide range of symptoms and signs. The most common features are:

  • Visual:
    • Very common, usually due to demyelination of the optic nerve.
    • Can cause blindness or hemianopia.
    • Optic neuritis is an acute, sometimes painful, reduction or loss of vision in one eye and is a relatively common presenting symptom of MS.
  • Eye movements:
  • Facial weakness:
    • Bell's palsy can occur alone or with other indications of brainstem disorder.
    • Other features may include one or more of trigeminal neuralgia, paroxysmal dysarthria and ataxia (with a clumsy arm, disturbed sensation and painful tetanic posturing of the limb, lasting 1-2 minutes).
    • There may be other paroxysmal symptoms, which may include one or more of the following: bursts of pain, bursts of paraesthesia, itching, cough, hiccup, painful spasm and complex gaze palsies.
  • Hearing and balance:
    • Deafness can occur and feelings of unsteadiness are common.
    • Acute demyelination in the brainstem causes severe positional vertigo, vomiting, ataxia and headache.
  • Cognitive symptoms:
    • Visual and auditory attention may be affected, occasionally in the early stages.
    • Effects on intelligence increase with duration of the disease and onset of the progressive phase, causing loss of memory more than language skills.
  • Psychological symptoms:
    • Psychotic symptoms are rare but depression is common.
  • Taste and smell:
    • Frequently found if specifically looked for.
  • Unpleasant sensations:
    • Tightness, burning, twisting, tearing and pulling sensations may be reported due to damage to the posterior columns in the cervical cord.
    • When the spinothalamic tract is involved this causes loss of thermal and pain sensation.
    • Nonspecific tingling is common.
  • Paraesthesiae and numbness:
    • Loss of sensation in the legs ascending to the trunk is caused when spinal nerves of the dorsal or lumbar segments are affected.
    • May be sacral sparing but a characteristic feature in MS is numbness of the perineum and genitalia with altered sphincter function.
  • Transverse myelitis:
    • An acute episode of weakness or paralysis of both legs, with sensory loss and loss of control of bowels and bladder; requires urgent hospital admission.
  • Autonomic system:
    • Bladder symptoms: loss of inhibition of reflex bladder emptying causes urgency and frequency with incontinence when there is associated immobility. May alternatively be impaired bladder emptying. Faecal incontinence due to impaired rectal sphincter is less common.
    • Sexual problems: impotence is common in men; there may also be problems of spasticity, altered sensation and problems with indwelling catheters.
    • Loss of thermoregulation: excess sweating, pyrexia or hypothermia.
  • Other symptoms:
    • These include Horner's syndrome, abnormal cardiac rhythm, abnormal vascular responses (with acute pulmonary oedema), weight loss, and inappropriate antidiuretic hormone (ADH) secretion.
  • Hereditary spastic paraplegia: mimics familial MS; other inherited diseases can also appear as MS.
  • Cerebral variant of systemic lupus erythematosus (SLE) can present with features of MS without other clinical manifestations of SLE.
  • Sarcoidosis.
  • In patients of African or Asian origin, alternative diagnoses should be considered - eg, AIDs, tropical spastic paraplegia or neuromyelitis optica.
  • Before referring to a neurologist, exclude differential diagnoses by checking FBC, Inflammatory markers, U&E, LFT, TFT, glucose, HIV serology, calcium and B12 levels.
  • Electrophysiology: can detect demyelination in apparently unaffected pathways with characteristic delays. Visual evoked potential studies should be the first choice.
  • MRI scan: 95% of patients have periventricular lesions and over 90% show discrete white matter abnormalities. Areas of focal demyelination can also be seen as plaques in the optic nerve, brainstem and spinal cord. By using a contrast agent, active inflammatory plaques can be distinguished from inactive ones. The number and size of lesions do not correlate well with disease activity or progress. It also excludes other lesions producing the symptoms.
  • Cerebrospinal fluid: rise in total protein with increase in immunoglobulin concentration with presence of oligoclonal cases.
  • Doctors and patients can use Decision Aids together to help choose the best course of action to take.
  • Compare the options  

General measures

The management of people with MS should include:[2] 

  • Good communication with patients and their carers.
  • Provision of written information regarding the disease, treatments and available help and support.
  • Informing them of their legal obligation to notify the DVLA of their condition.
  • Ensuring all available help and support with rehabilitation, employment and mobility.
  • Encouraging autonomy/self-management.
  • Support to the family and carers, including respite care.
  • Close co-operation and communication between all health professionals involved in caring for the person (including their GP, nurse specialists and specialists).

Pharmacological

Relapses

  • Any episode of sudden increase (ie over 12-24 hours) in distressing symptoms or an increased limitation on activities should be assessed promptly. Symptoms should be discussed with a clinician with expertise in MS to decide whether oral or intravenous (IV) methylprednisolone treatment is required.[2] A urinary tract infection should be excluded as the cause of the exacerbation of symptoms before steroids are considered. The course should be started as soon as possible after onset of the relapse:
    • The usual dose is 500 mg/day methylprednisolone for five days. This is given as a day-case treatment but admission may be arranged if required by the patient.
    • IV infusion is given over four hours. Oral medication (as 5 x 100 mg tablets) is also available.
    • Patients often notice an unpleasant metallic taste with this treatment.
    • It is no longer considered necessary to taper doses down after this course.
    • Gastric protection should be provided by ranitidine 150 mg bd, or omeprazole 20 mg daily.
    • The use of steroids on more than three occasions per year, or for longer than three weeks on any one occasion, should be avoided.
  • There is some evidence that azathioprine is beneficial in reducing relapses and progression of MS, and is therefore an appropriate maintenance treatment for patients with MS who frequently relapse and require steroids.[4] 

Disease-modifying therapy
Any woman receiving disease-modifying therapy (eg, interferon) must stop treatment for at least 12 months before trying to conceive.

  • Interferon beta:
    • This is licensed for use in patients with relapsing, remitting MS (characterised by at least two attacks of neurological dysfunction over the previous two or three years, followed by complete or incomplete recovery) who are able to walk 100 m unaided. Not all patients respond and a deterioration in the bouts has been observed in some.
    • Interferon beta-1b is also licensed for use in patients with secondary progressive MS but its role in this condition has not been confirmed.
    • It is given by subcutaneous (Rebif® and Betaferon®) or intramuscular (Avonex®) injection. Preparations vary but can be alternate days (Betaferon®), three times per week (Rebif®) or weekly (Avonex®).
    • The most commonly reported side-effect is a flu-like ague for 24 hours after the injection, which is effectively treated with ibuprofen. This lessens over time. Injection site reactions also occur but can be minimised with good technique and rotation of sites.
    • 10 years of clinical experience show a 30-40% relapse reduction.[5][6] There is some evidence for greater efficacy with Betaferon® and Rebif®, compared with Avonex®.[7] 
  • Glatiramer:
    • This is licensed for reducing the frequency of relapses in ambulatory patients with relapsing-remitting MS who have had at least two clinical relapses in the previous two years.
    • It is designed to mimic the effects of the main proteins in myelin.
    • Eight years of clinical experience show a 30% relapse reduction rate.[8]
    • It is given daily by subcutaneous injection.
    • Injection site reactions are common, as are flu-like symptoms. These decrease over time.
    • Sporadic, short-lived chest tightness and shortness of breath have been reported.
  • Dimethyl fumarate:
    • Dimethyl fumarate is recommended by the National Institute for Health and Care Excellence (NICE) as an option for treating adults with active relapsing‑remitting MS (two clinically significant relapses in the previous two years) but only if they do not have highly active or rapidly evolving severe relapsing‑remitting MS.[9] 
    • Dimethyl fumarate is taken orally: 120 mg twice daily for the first week and 240 mg twice daily thereafter.
  • Teriflunomide:[10] 
    • Recommended by NICE as an option for treating adults with active relapsing-remitting MS (two clinically significant relapses in the previous two years), only if they do not have highly active or rapidly evolving severe relapsing-remitting MS.
  • Alemtuzumab:[11] 
    • Also recommended by NICE as an option for treating adults with active relapsing-remitting MS.

NICE does not recommend either interferon beta or glatiramer acetate.[12] However, the Department of Health, the National Assembly for Wales, the Scottish Executive, the Northern Ireland Department of Health, Social Services and Public Safety, and the manufacturers have reached agreement on a risk-sharing scheme for the NHS supply of interferon beta and glatiramer acetate for MS.[13]

Second-line therapies

  • Natalizumab:
    • This is a recombinant humanised monoclonal antibody, produced in murine myeloma cells. NICE approval was granted in August 2007.
    • It is given monthly by IV infusion.
    • There is 68% relapse reduction.[14]
    • It is well tolerated but there have been several cases of progressive multifocal leukoencephalopathy (PML) in treated patients. Risk is currently estimated to be 1 in 600 cases, increasing with the number of treatments received. PML is thought to be caused by the John Cunningham (JC) virus.[15][16]
  • Fingolimod:
    • The first oral therapy for MS. Approved by NICE in April 2012.[17]
    • It works by preventing lymphocyte movement across the blood-brain barrier and causes a reversible lymphopenia.
    • It reduces the rate of relapses by 50% compared to placebo.[18]
    • The dose is 0.5 mg/day. Possible side-effects include first dose bradycardia, macular oedema and increased risk of infection.
  • Mitoxantrone:[19] 
    • Mitoxantrone shows a significant but partial efficacy in reducing the risk of MS progression and the frequency of relapses in patients affected by worsening relapsing-remitting MS, progressive relapsing MS and secondary progressive MS in the short-term follow-up (two years).
    • Studies with longer follow-up have raised concerns about the risk of systolic disfunction and acute leukaemias. Mitoxantrone should be limited to treating patients with worsening relapsing-remitting MS and secondary progressive MS and with evidence of persistent inflammatory activity after a careful assessment of the risk and benefit profiles of individual patients.
    • Assessment should also consider the present availability of alternative therapies with less severe adverse events.

Other treatments

  • Cannabinoids:
    • There is a great deal of anecdotal evidence for the therapeutic benefits of cannabis for a variety of MS symptoms, including spasticity, tremor, bladder problems and pain.
    • Sativex® oromucosal spray is now licensed in the UK on a named patient basis.
    • NICE advises cannabis should not be used in the treatment of spasticity in MS.[2] 
  • Percutaneous venoplasty:
    • Venoplasty (with or without stenting) is being used in some (non-NHS) centres. The theory is based on the premise that MS is partly caused by chronic insufficiency in the venous drainage of the brain.
    • NICE states that current evidence on the efficacy of percutaneous venoplasty for chronic cerebrospinal venous insufficiency for MS is inadequate in quality and quantity.[20] .

General problems

Fatigue

  • First consider and treat any underlying causes - eg, depression, disturbed sleep, chronic pain and poor nutrition.
  • Advise fatigue may become worse with heat and stress.
  • Medication should also be reviewed; some medications (eg, interferon beta) have fatigue as a side-effect.
  • Advise that aerobic exercise or yoga may be beneficial.
  • Offer amantadine for fatigue but also consider mindfulness-based training or cognitive behavioural therapy (CBT).[2] 

Pain

  • This may be of neuropathic origin or from musculoskeletal problems, secondary to reduced mobility.
  • It may need suitable analgesia and, if still a problem, transcutaneous electrical nerve stimulation (TENS) or antidepressant medication.
  • Cognitive behavioural and imagery treatment methods may also be beneficial.
  • Neuropathic pain should be treated using anticonvulsants such as carbamazepine or gabapentin, or using antidepressants such as amitriptyline.

Visual and communication

Visual problems

  • Difficulty in reading or seeing television is not uncommon and the usual reason (other than the lack of glasses) is that the control over eye movement is poor.
  • Actual loss of visual function due to optic neuritis is rare.
  • Visual disturbance associated with MS requires an ophthalmological opinion.
  • The patient should be assessed for glasses by an optometrist and, if necessary, at a specialist ophthalmology clinic.
  • If nystagmus is causing reduced visual acuity or other visual symptoms, offer a trial of treatment with oral gabapentin (initiated and monitored in a specialist clinic).
  • May need low-vision equipment and adaptive technology and require to be registered as sight impaired.

Speech difficulties

  • Dysarthria may cause great difficulty. This should be assessed and advice given by a specialist speech and language therapist.
  • May need alternative non-verbal means of assisting with or replacing speech.

Motor problems

  • Weakness and cardiorespiratory fitness:
    • Exercises and techniques to maximise strength and endurance appropriate to their circumstances, including aerobic training.
    • Motor weakness may require equipment - eg, orthoses or specialist supportive equipment for postural difficulties.
  • Spasticity and spasms:
    • Consider and explore possible aggravating factors - eg, pain, infection.
    • Advice on physical techniques - eg, passive stretching, to reduce spasticity and avoid the development of contractures.
    • Baclofen or gabapentin are the drugs of choice if required.
    • Tizanidine and dantrolene are recommended second-line treatments if treatment with baclofen or gabapentin is unsuccessful or the side-effects are intolerable. Benzodiazepines may be used as third-line agents. There are only poor-quality data regarding the comparative efficacy and tolerability of anti-spasticity agents and a Cochrane review concluded that no recommendations could be made to guide prescribing.[21]
    • Troublesome spasticity and spasms should be assessed by a specialist team. Intramuscular botulinum toxin can be considered for relatively localised hypertonia or spasticity that is not responding to other treatments.
    • Contractures at joints: specific treatments include prolonged stretching - eg, with serial plaster casts.
  • Ataxia and tremor:
    • Should be assessed by a specialist rehabilitation team.
    • If problems remain severe and intractable, the person should also be assessed by a neurosurgical team for suitability for operative intervention.
  • Pressure ulcers:
    • Many people with MS are at high risk of developing pressure ulcers because of, for example, limited mobility, impairment of sensory functioning and reduced cognitive function.
    • Most pressure ulcers can be avoided.

Urological

  • Bladder symptoms: check for underlying urinary tract infection and assess postmicturition residual bladder volume by ultrasound.[22]
  • Urgency or urge incontinence:
    • Offer convene drain (for men) or pads (for women); consider toilet arrangements (eg, a commode downstairs) and intermittent self-catheterisation if there is a high residual volume.
    • Consider anticholinergics (eg, oxybutynin, tolterodine).
    • Desmopressin may be used for night problems or to control urinary frequency during the day but should never be used more than once in 24 hours.
    • Continued incontinence, despite treatment, can be treated by a course of pelvic floor exercises preceded by a course of electrical stimulation of the pelvic floor muscles.
    • Continued bladder symptoms may require intermittent self-catheterisation or longer-term urethral catheterisation. Suprapubic catheterisation is useful if active sexual function is wanted.

Gastroenterological

  • Urgency, pain, constipation or incontinence may occur.
  • Faecal incontinence may be due to constipation with overflow, possibly exacerbated by laxative use.
  • Constipation may require the routine use of suppositories or enemas.
  • Swallowing difficulties:
    • Dysphagia may lead to choking and aspiration of food or liquid, leading to chest infections.
    • Assessment is advised if there are any symptoms or chest infections.
    • Should be assessed by a specialist speech and language therapist and given advice on specific swallowing techniques and on adapting food consistencies and dietary intake.
    • May need further assessment (eg, by videofluoroscopy), possibly short-term nutritional support via nasogastric tube or percutaneous endoscopic gastrostomy (PEG) tubes.

Higher functions

  • Cognitive losses:
    • About half of all people with MS may have impaired ability to learn and remember, to plan, to concentrate and to handle information quickly.
    • If such problems occur, review medication and assess for depression.
    • A formal neuropsychological assessment by a specialist clinical psychologist (and speech and language therapist if appropriate).
  • Emotionalism:
    • May cry or laugh with minimal provocation and with little control.
    • A full assessment of their emotional state may be required and antidepressant medication and/or advice on behavioural management strategies may be beneficial.
  • Depression:
    • Assessment should include all contributory factors (eg, chronic pain or social isolation) and consideration of interventions to ameliorate these.
    • Antidepressant medication or CBT should be considered as part of an overall programme.
  • Anxiety: may require psychologically based treatment or medication such as antidepressants or very short-term benzodiazepines.

Sexual dysfunction

  • May disturb the normal sexual physiology and it may result in other impairments (such as spasms) that make normal sexual behaviour difficult.
  • If sexual dysfunction is persistent, specific treatments (eg, sildenafil) should be offered and discussed.
  • Male sexual dysfunction: erectile dysfunction needs full assessment of possible causes such as anxiety and, possibly, medication.
  • Female sexual dysfunction: full assessment of general and specific underlying factors that might cause or worsen sexual dysfunction and that are amenable to treatment.

Other considerations

  • Infections may be associated with a worsening of disability and may trigger a relapse. People with MS should be offered immunisation against influenza. People with relapsing-remitting MS should be warned that vaccination may trigger a relapse.
  • Complementary therapies: there is some evidence to suggest possible benefit from some complementary therapies - eg, reflexology and massage.
  • People with MS should be advised that linoleic acid 17-23 g/day may reduce progression of disability.
  • Fish oils may also be beneficial.
  • Patients may spend many years in each of these phases or quickly progress to one of fixed progressive disability. Approximately 25% of patients have a non-disabling form of MS. 5% of patients have frequently recurring relapses without recovery, rapidly causing disability and early death. Up to 15% of patients are severely disabled within a short period.
  • Episodes occur initially at approximately 1.5/year with recovery being slower than onset of symptoms (and may be incomplete). Secondary progressive MS tends to affect those systems previously involved in a relapsing-remitting stage.
  • 20% of cases are progressive from onset (primary progressive) - this is mainly in older patients and these have a poorer prognosis.
  • Relapse rate is reduced during pregnancy but increases again after delivery.
