[stroke] Flashcards
Endocarditis
AF
MI
Prosthetic valves
[stroke]: Where in the brain does a ‘watershed/boundary zone’ stroke occur (not a brain area )
Infarct in the area between the supply of two arteries (i.e. decreased blood supply).
[stroke]: When does a ‘watershed/boundary zone’ stroke occur
Sharp drop in BP (sepsis)
CADASIL
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy)
+ rare inherited disorder
+ thickening of the walls of small- and medium-sized blood vessels blocks the flow of blood to the brain
