Kalika is told by her physician that her symptoms are caused by a loss of myelin. Her diagnosis would most likely be
A) Parkinson's disease.
B) multiple sclerosis.
C) early stage Alzheimer's disease.
D) epilepsy.
Answer: B
Rationale: Multiple sclerosis is a disease in which the immune system does not recognize myelin and attacks it. This can devastate the structural and functional integrity of the nervous system. When myelin breaks down in multiple sclerosis, the resulting symptoms include numbness or tingling sensations. This reflects the disruption of sensory nerve cell signals reaching the brain. The disorder also involves problems with voluntary, coordinated movement, which is due to the breakdown of myelin that supports motor nerves.
