Question

An important cause of multiple sclerosis involves?

1) a lack of an enzyme needed for myelinization.
2) the formation of neurofibrillary tangles.
3) the conversion of MPTP to MPP+.
4) damage to myelin induced by the person's immune system.
5) low levels of the β-amyloid protein.

Answer 1

Multiple sclerosis (MS) is an inflammatory disease where the immune system attacks the myelin sheath that insulates neurons in the brain and spinal cord, leading to a variety of symptoms.

Step-by-step explanation:

Multiple sclerosis (MS) is an inflammatory disease of the myelin sheath that insulates neurons in the brain and spinal cord. The immune system attacks the myelin, leading to its breakdown and impairing signal transmission.

MS symptoms include fatigue, vision problems, weakness of arms and legs, loss of balance, and tingling or numbness in one's extremities (neuropathy). It is more common in younger adults, especially females.

Causes of MS might come from infection, environmental or geographic effects, or genetics. At the moment, there is no known cure for MS.
