Answer 1

Multiple sclerosis is associated with damage to the myelin of the CNS.

Step-by-step explanation:

Multiple sclerosis is a demyelinating disease that affects the brain and spinal cord.

It is characterized by distinct episodes of neurologic deficits separated in time, attributable to white matter lesions separated in space .

It is common at higher latitudes (1:1000 US, Europe)

It's onset is any age, usually 20-40yrs; It occurs in more females compared to males at a ratio 2:1.

Myelin in CNS destroyed by immune cells (macrophages) and this leads to slow conduction which in turn leads to limb weakness/paralysis and loss of co-ordination.
