MS is characterized by remissions and exacerbations. What happens to the myelin during
each of these phases?
What will be an ideal response?
During remission, the myelin can regenerate and transmission of the nerve impulse is restored.
Symptoms decrease or disappear during this phase. The inflammation can recur and cause
exacerbations. If it is severe, it can cause irreversible destruction of the myelin with dense scar tissue,
forming sclerotic plaques. The plaque permanently damages the CNS.
