Demyelinating diseases involve damage to this protective covering, leading to impaired nerve signaling.
Step 3: Analysis
Multiple sclerosis (MS) is the hallmark demyelinating disease where the immune system attacks the myelin in the central nervous system. Polio affects motor neurons; Leprosy affects peripheral nerves and skin; Alzheimer's is a neurodegenerative disease involving amyloid plaques.
