Extra section was very busy w/ extra information for this card already covered by basic concept myelin cards re: space/time constant elsewhere. Updated it to explain the difference in "myelin" loss as opposed to "oligodendrocyte" loss, which reads as redundant on its own and seems to be a confusion point given suggestion history on this card.
Based my description on AMBOSS pathophysiology section: "Most commonly accepted theory: Activation of autoreactive T-lymphocytes → inflammatory processes → focal demyelination with partial preservation of axons (acute plaques) → loss of axons and atrophy of oligodendrocytes (chronic plaques) → gliosis → inadequate remyelination" https://next.amboss.com/us/article/WR0PNf?q=multiple%20sclerosis#Z31360d67aa0be6b83f52c446fd30c0c1
