Study Notes
- Multiple Sclerosis (MS) is an autoimmune disorder
Definition of MS
- Attacks the myelin sheath around nerves
- Disrupts nerve impulse transmission, which impairs communication between the brain and body
- Presents with sensory, motor, bowel, and bladder disturbances
- Symptom attacks vary, with location, severity, and duration lasting from days to months
- Diagnosis involves ruling out other conditions
Types of MS
- There are four types of MS
Relapsing-Remitting MS (RRMS)
- Most common, accounting for 85% of cases
- Characterized by flare-ups followed by remission
- Remyelination may occur during remission
- Relapses can last days to months
- Remission can last weeks to years
Primary-Progressive MS (PPMS)
- Accounts for 10% of patients
- Involves continuous worsening from onset without clear remissions
- May include temporary minor improvements or plateaus
Secondary-Progressive MS (SPMS)
- Develops within 10 years of RRMS if untreated
- Begins as RRMS and then progresses continuously
- Has fewer remissions, though flare-ups may still occur
- Caused by destruction of oligodendrocytes, preventing remyelination
Progressive-Relapsing MS (PRMS)
- Rare, accounting for 5% of cases
- Features steady progression with acute relapses
- Has no true remission as symptoms continuously worsen
Etiology (Causes & Risk Factors)
- MS is an immune-mediated disease with an unknown antigen
- Possible environmental triggers: geography, sunlight exposure, and toxins
- Can be caused by infectious agents
- There is a genetic predisposition to MS
- Higher risk age group: 20-40, but can occur as young as 2, as old as 75
- Women are three times more likely to develop relapsing forms than men
- Smokers have a higher risk of developing MS and faster disease progression
Clinical Manifestations (Signs & Symptoms)
Neurological & Motor Symptoms
- Fatigue
- Paresthesia (numbness, tingling, burning)
- Lack of coordination, balance issues, unsteady gait, and tremors
Bladder & Bowel Dysfunction
- Urinary urgency, incontinence, and constipation
Visual Disturbances
- Unilateral vision loss, optic neuritis, double vision, and blurred vision
- Oscillopsia (vibration of objects in vision)
- Red-green color distortion
Other Symptoms
- Dizziness
- Sexual dysfunction
Disease Course
- Symptoms may persist, go into remission, or worsen depending on immune activity
- No two patients have the exact same symptoms
Treatment & Prognosis
- There is no cure for MS currently
- Treatments focus on managing symptoms, slowing progression, and improving quality of life
