CVA

Question 1

types of stroke

Answer 1

ischemic

hemorragic

Question 2

ischemic stroke

Answer 2

blocked blood flow to brain

Question 3

types of ischemic stroke

Answer 3

thrombotic

embolic

Question 4

embolic stroke

Answer 4

blood clot forms somewhere in the body and travels to the arteries supplying blood to the brain and disrupts blood flow

Question 5

thrombotic stroke

Answer 5

buildup forms on the walls of one or more of the arteries supplying blood to the brain, disrupting blood flow

Question 6

hemorragic stroke

Answer 6

bleeding in the brain

• caused by breakage of a blood vessel wall in the brain
• this bleeding increases intracranial pressure that can kill or damage brain tissue

Question 7

scanning that is done to confirm stroke dx

Answer 7

CT
other tests:
ECG
Chest X ray
blood tests

Question 8

time frame of OT referral after stroke

Answer 8

24-48 hours after hospital admission

-possible to see decline in fxn after initial assessment

Question 9

how does neurological recovery occur after stroke?

Answer 9

1. undamaged systems (typically those that do not have a specific function) are recruited to compensate
   - shown to happen in 30 min of practice, but reverses after 30 min of nonpractice
2. dendrite branching and axonal sprouting (formation of new synapses)
3. Active movement is important!

Question 10

why is active movement important in neurological recovery?

Answer 10

increases cortical area in relation to limb performance

-passive movement and repetitive activity alone do not produce functional reorganization
