Unit 14 - Stroke/CVA Flashcards
5th leading cause of death in the US
stroke
a condition in which neurological deficits result from
a sudden decrease in blood flow to a localized area of the brain
stroke (also known as a cerebrovascular accident or brain attack)
Strokes may be _____, occurring when the blood supply to a part of the brain is suddenly interrupted by a thrombus (blood clot), embolus (foreign matter traveling through the circulation), or stenosis (narrowing);
ischemic
Strokes may be _____, occurring when a blood vessel breaks open, spilling blood into spaces surrounding neurons.
hemorrhagic
~87%of all strokes are_____
Ischemic
Blood flow to the brain is blocked
Usually a thrombus or embolism, or stenosis ( build up of plaque) that causes infarction of brain tissue

- Subarachnoid or intracranial hemorrhage caused by a ruptured _____
- intracerebral hemorrhage related to _____ _____ (proteins called amyloid build up on the walls of the arteries in the brain weakening walls)
- arterial venous _____ (AVMs)
- medications such as _____
aneurysm
amyloid angiopathy
malformations
anticoagulants
hemorrhagic clinical manifestations
severe headache
- Temporary neurologic deficit resulting from a temporary impairment of blood flow ( must return to normalcy within 24 hrs.)
- Diagnostic workup is required to treat and prevent irreversible deficits/ prevent future stroke.
