Study Notes
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
