Multiple Sclerosis (MS)

Demyelinating disorder: damage to myelin nerve sheet
Occurs in the central nervous system (CNS) or peripheral nervous system (PNS)
Chronic inflammatory disease, progressive, leading to permanent disability
Characterized by central nervous system demyelination (destruction of normal myelin on axons in CNS)
- Scarring, formation of plaques, loss of axons
Leading cause of neurological disability in early adulthood
3 times more common in females compared to males, highest prevalence in white populations
Etiology includes genetic, environmental factors, and autoimmunity. Regional variation, higher incidence in temperate regions
Clinical symptoms include impaired vision due to optic neuritis, spasticity, paresthesia, slurred speech, fatigue, pain, bladder and bowel dysfunction, impaired extraocular eye movement, loss of vision, altered color perception, nystagmus, and pseudobulbar effect (uncontrolled laughing/crying)

Multiple Sclerosis (MS) Pathophysiology

Pathophysiology of demyelination
Presentation of clinical manifestation, including
- Clinically isolated syndrome: initial presentation of symptoms
- Relapsing-remitting: periods of acute neurologic symptoms alternating with periods of symptom relief.
- Primary progressive: steady and continuous deterioration of neurologic function without periods of remission.
- Secondary progressive: started as relapsing-remitting, develops a constant decline in function.
- Progressive-relapsing: steady decline with occasional worsening episodes (relapses).

Multiple Sclerosis (MS) Diagnostic Criteria

Based on clinical manifestation: presence of signs and symptoms, history, physical exam, neurologic exam and imaging (MRI) and evoked potentials testing.
Testing electrical activity in special sensory nerve pathways, such as visual evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs).
Diagnosis involves combined subjective (symptoms), objective (physical exam findings), and diagnostic tests to assess for lesions.
Diagnosis often relies on number of flare-ups/clinical attacks, and the number of lesions identified.

Multiple Sclerosis (MS) Treatment

No cure for MS exists
Pharmacologic disease-modifying drugs target the symptoms. Delays progression of the disease as well as immunomodulators and immunosuppressants
Non-pharmacologic methods include balanced rest and activity, and assistive devices
