Multiple Sclerosis (MS) Overview

Definition and Overview

• Multiple sclerosis (MS) is a chronic and often disabling autoimmune disease that affects the central nervous system (CNS)
• The immune system attacks and damages the protective covering of nerve fibers, called myelin, leading to communication disruptions between the brain and the rest of the body

Causes and Risk Factors

• The exact cause of MS is unknown, but it is believed to involve a combination of genetic and environmental factors
• Risk factors include:
  • Family history
  • Age (typically affects people between 20 and 50 years old)
  • Gender (women are more likely to be affected)
  • Ethnicity (Caucasians are more likely to be affected)
  • Geography (people living in temperate climates are more likely to be affected)

Symptoms

• Symptoms vary widely from person to person and can change over time
• Common symptoms include:
  • Vision problems (blurred vision, double vision, loss of vision)
  • Muscle weakness or numbness
  • Tingling or pins-and-needles sensations
  • Fatigue
  • Balance and coordination problems
  • Cognitive difficulties (memory, attention, processing speed)

Diagnosis

• Diagnosing MS typically involves a combination of:
  • Medical history and physical examination
  • Laboratory tests (blood tests, spinal fluid analysis)
  • Imaging tests (MRI, evoked potentials)

Types of MS

• Relapsing-remitting MS (RRMS): the most common type, characterized by clearly defined relapses with periods of partial or complete recovery
• Secondary progressive MS (SPMS): a type of MS that follows an initial relapsing-remitting course, but then becomes steadily progressive
• Primary progressive MS (PPMS): a type of MS that progresses steadily from the beginning, with no distinct relapses
• Progressive-relapsing MS (PRMS): a rare type of MS that has a steady progression from the beginning, but also has distinct relapses

Treatment and Management

• There is no cure for MS, but various treatments can help manage symptoms and slow disease progression
• Treatment options include:
  • Disease-modifying therapies (DMTs) to reduce relapses and slow disease progression
  • Steroids to reduce inflammation during relapses
  • Medications to manage specific symptoms (e.g. pain, fatigue, bladder problems)
  • Lifestyle modifications (e.g. exercise, stress management, balanced diet)
