CEREBROVASCULAR ACCIDENT Flashcards
Common cause of CVA :
thrombosis, embolism,
cerebral hemorrhage
Caused by disruption of the blood supply to the brain,
causing neurologic deficit
CEREBROVASCULAR ACCIDENT
with temporary episodes of neurologic
dysfunction.
Transient Ischemic Attacks (TIA) is a transient
ischemia with
small arteries in the white matter of the
brain account for the most common cause of stroke.
THROMBOSIS
e second most common cause of CVA,
and happens when a blood vessel is suddenly
occluded with blood, air, tumor or septic particul
EMBOLISM
usually the sudden result of ruptured aneurysms,
tumors or involves hypertension or bleeding
dyscrasias
HEMORRHAGE
outermost layer of brain cell
● Cortex
- basic functions like breathing and
sleeping
Brainstem-
cluster of structures in brain center
Basal ganglia
- coordination and balance
Cerebellum
are responsible for problem solving and
judgment and motor function
- The frontal lobes
manage sensation, handwriting, and body
position
- The parietal lobes
are involved with memory and hearing
temporal lobes
contain the brain’s visual processing
system.
occipital lobes
amount of blood received by brain per minute
750ml-
TIA early signal-
