Answer 1

Identify the autoimmune disorder that is associated with scarred a deteriorating myelin

A. Multiple sclerosis - Correct Answer. This is an autoimmune disorder in which auto-antibodies are directed against the myelin sheath. The destruction of the myelin sheath leads to demyelination and scarring. Symptoms include weakness, tingling, numbness, and blurred vision. It has a prolonged course. It is the most common cause of neurological disability in young and middle-aged adults. Current treatment options are limited. There is currently no cure for MS.

B. Spina Bifida - This can be ruled out because it is a birth defect that occurs when the spine and spinal cord don't form properly. It's a type of neural tube defect.

C. Muscular Dystrophy - Muscular dystrophy refers to a group of genetic disorders that cause progressive weakness and loss of muscle mass due to mutations in the muscle proteins.

D. Rheumatoid Arthritis - This is an autoimmune disorder. But it predominantly affects females. Autoantibodies are produced against the tissue in the joints. It is an inflammatory disorder and has a long chronic course. It may cause severe and disabling deformities of the joints in the hands.
