I have a question re strokes. It involves the interface and damage of strokes in micro vessels and the resultant nerve and myelin damages that typically occurs in Cadasil disease. When a stroke occurs, oxygen is not supplied to the nerve, and this interrupts the ADP ATP cycle with the nerve's eventual death through a complex ischemic cascade. My question is:
How is oxygen supplied to the nerve? Is it dumped into a pool and made available to multiple nerves and then picked up by the nerves through ports the way neurotransitters are. Or is there a different sort of delivery system altogether.
And how does the myelin damage occur. Does the nerve damage cause the myelin damage, or does the myelin damage occur first like they describe in MS, then the nerve gets damaged.
