Understanding Multiple Sclerosis (MS)

Multiple Sclerosis (MS)

• MS is an inflammatory disease targeting the myelin and axons in the central nervous system, causing significant disability.
• The hallmark of MS is episodic symptoms appearing months or years apart, affecting various areas of the CNS.
• Plaques or sclerosed areas characterize the disease, resulting in multiple neurological symptoms.
• MS typically develops between 20 and 50 years of age.
• Women are diagnosed with MS twice as often as men.
• People of Northern European descent are more prone to developing MS.

Risk Factors

• Family history of MS, autoimmune disorders, or migraine
• Personal history of autoimmune disorders or migraine
• Cigarette smoking, especially during childhood and adolescence
• Obesity (especially in childhood and adolescence)
• Vitamin D deficiency
• Genetic factors
• Epstein-Barr virus

Diagnosis of MS

• MS is not contagious or infectious.
• It is not the most common disease of the central nervous system in young adults.
• Various clinical tests aid in the diagnosis, including:
  • MRI scans
  • Evoked potential tests
  • Spinal tap
  • Vision tests

Types of MS

• Relapsing-remitting MS (RRMS): ~85% of patients experience periods of remission followed by relapses. Disability is stable between relapses.
• Secondary progressive MS (SPMS): ~50% of RRMS patients transition to SPMS within 10 years of diagnosis, characterized by gradual progression of disability.
• Primary progressive MS (PPMS): ~10% of patients experience gradual progression of disability from disease onset. No relapses occur.
• Progressive relapsing MS: <5% of the patient population
  • Primary progressive onset and later relapses

Important Points

• "Remitting" does not mean the absence of disease activity, only that there are no detectable signs or symptoms.
• Underlying damage to myelin and neurons may persist despite remission.

Common Symptoms

• Bladder and bowel dysfunction
• Cognitive dysfunction
• Dizziness and vertigo
• Depression
• Fatigue
• Difficulty walking
• Stiffness
• Numbness
• Sexual dysfunction
• Pain
• Visual problems
• Inflammation of optic nerve
• Ataxia (loss of full body movement control)
• Nystagmus (involuntary eye movements)
• Weakness in Limbs
• Spasticity (stiffness)
• Hemi or paraparesis (partial paralysis)
• Diplopia (double vision)
• Numbness and tingling
