Multiple Sclerosis and Fatigue Quiz

Multiple Sclerosis (MS) Overview

• MS is an autoimmune inflammatory disease
• It attacks the myelin sheath of axons in the central nervous system.
• This leads to demyelination and neuron damage.

Prevalence and Demographics

• MS is not a rare disease, with a global incidence of 0.1%.
• 400,000 people in the US have MS.
• Predominant age of onset is 20-40.
• Higher incidence in Northern European descent in temperate climates.

Pathogenesis

• The disease involves two primary pathogenic processes.
• The first is an inflammatory, demyelinating process, which is recurring and relapsing, seen in focal lesions within the CNS.
• The second is a neurodegenerative process. This includes high levels of inflammation and leads to a gradual loss of function.
• Immune system cells, such as T cells and macrophages, attack the myelin sheath in the CNS.

Clinical Picture

• Any myelinated area in the CNS can be affected.
• Symptoms may include sensory manifestations (e.g., numbness, tingling), speech disorders, motor disorders (e.g., Paraplegia, Quadriplegia, Ataxia), bladder dysfunction, and visual problems (e.g., optic neuritis).

Clinical Manifestations

• Multiple sclerosis can present with a wide range of symptoms often affecting different parts of the body and may evolve over time.
• There are different types of MS that manifest differently and can evolve at different rates of severity and progression.

Neurological Examination

• Mental function: Impaired memory and concentration are common, along with possible anxiety or depression.
• Speech assessment: Speech problems, may arise due to spasticity, tremors, or ataxia.
• Cranial Nerve Examination: Cranial nerve involvement is possible in various forms.
• Sensory examination: Sensory abnormalities like paresthesia or complete loss of sensation can occur in "glove-and-stocking" distributions or more diffuse affected areas.
• Deep sensation: Impairment of position and vibration senses in the body is common.
• Motor assessment: Observe posture, look for cerebellar issues, and vestibular dysfunction.
• Muscle tone assessment: Muscle tone may be normal, hypotonic, or spastic, with spasticity being very common.
• Muscle strength assessment: LMN (lower motor neuron), or UMN (upper motor neuron) weaknesses can be found differently in the body.
• Respiratory assessment: Respiratory dysfunction including reduced tolerance to exercise is possible but not always present.

Functional Systems for Scoring EDSS

• Pyramidal functions (e.g., reflexes, muscle power).
• Cerebellar functions (e.g., tremors, ataxia).
• Brainstem functions (e.g., cranial nerve issues).
• Sensory function (e.g., light touch).
• Bowel and bladder function (e.g., incontinence).
• Visual function (e.g., acuity, visual field).
• Mental functions (e.g., fatigue).

Expanded Disability Status Scale (EDSS)

• Grading system: EDSS grades the severity and extent of MS.
• Factors: Evaluation based of walking ability, assistance needs, functional systems scores across several areas of the body.

Course of Disease

• Relapsing-remitting (RRMS): Characterized by episodes of relapse followed by periods of remission.
• Primary progressive (PPMS): A continuous decline in function from the onset of the disease.
• Secondary progressive (SPMS): Starts with relapsing-remitting and transitions to a progressive phase.

Fatigue in MS

• It is a common and debilitating symptom.
• Common causes can include motor disabilities, comorbid conditions, depression, or sleep disorders.

Diagnosis of MS

• MRI: Identify characteristic lesions in the brain and spinal cord.
• Evoked potentials: Measure nerve conduction through the various areas of the body's connections
• CSF analysis: Identify signs specific to autoimmune conditions.

Importance of Early Treatment

• Early diagnosis and treatment are crucial.
• Early interventions can help to slow disease progression and manage symptoms.

Treatment

• Treatment for attacks (Relapse treatment): Short-term corticosteroids.
• Long-term therapy (disease-modifying therapy): Interferon and other disease-modifying therapies are used in the long-term to try to slow disease evolution.
• Symptomatic management: Address specific symptoms and improve quality of life.

Physiotherapy Interventions

• Every patient has differing needs according to the progression stage. type, severity, and localized affected areas.
• Aims of physiotherapy include managing attacks, improving mobility between attacks, and preventing complications..

Sensory, Motor, and other Treatment

• Sensory re-education targets improve sensation problems in both hypoesthesia and hyperesthesia.
• Treatments such as tapping, approximation, and other exercises targeting different areas of coordination, balance, and stability help to manage symptoms.

Vertigo Assessment

• Vertigo is characterized by the feeling of spinning/rotational movement of the body whether self or surroundings.
• Visual analogue scale (VAS) is a tool to measure intensity of vertigo and is useful for assessment of severity.

Pain Management

• Headaches, trigeminal neuralgia, and Lhermitte pain are all possible issues that could be addressed with pain management techniques.

ADL Activities and Hand Function

• Occupational therapy and assistive/adaptive devices can help with daily living activities.

Patient and Family Education

• Education for patients and families regarding disease process, symptoms, management, and strategies to reduce risk of complications.

Temperature and Cooling

• Important for managing fatigue.

Cognitive Behavioral Therapy

• Helpful for managing fatigue as it assists with improved motor planning.

Bladder Rehabilitation Interventions

• A variety of interventions to address bladder dysfunction that may arise in MS can be addressed.

Gait Assessment

• Observation and analysis to address gait dysfunction due to MS and any contributing conditions.

Treatment for vertigo

• There are several treatments available depending on the nature and severity of the vertigo in relation to MS, including vestibular rehabilitation therapy and habituation exercises.

Gaze stability and eye movement exercises

• There are several exercise regimens targeting these issues and improving eye-movement skills, stability, and coordination

Other Important Considerations

• The need to assess other factors including lifestyle modifications, nutritional needs based on MS and any comorbidities in relation to treatments are also pertinent to include in care plans.
