Stroke Flashcards
a condition in which plaque builds up inside the arteries, leading to the narrowing and hardening of the blood vessels, increasing the risk of stroke
atherosclerosis
Occurs when blood flow to a part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients, leading to cell damage and neurological deficits
CVA/Stroke
weakness on 1 side of the body
hemiparesis
paralysis on 1 side of the body
hemiplegia
increased muscle tone, resistance to passive movement, often developing after stroke
spasticity (hypertonia)
decreased/absent muscle tone, present immediately after a stroke d/t cerebral shoke
flaccidity (hypotonia)
predictable pattern of muscle activation occurring involuntarily, limiting isolating joint movements, often seen in stroke recovery
synergy
impairment of language comprehension, formulation and use. resulting from L hemisphere damage
aphasia
difficulty speaking
dysarthria
difficulty swallowing
dysphagia
perceptual deficit in which the individual fails to report, respond, or orient to stimuli presented to the side opposite their brain lesion, despite intact sensory function.
unilateral neglect
visual defect, loss of vision in the same half of visual field in both eyes
homonymous hemianopsia
temporary disruption of blood flow to the brain, causing stroke-like sx that resolve within minutes or hours; often a warning sign for potential future stroke
TIA: Transient Ischemic Attack
type of stroke caused by blockage (thrombus/emboli) in an artery supplying blood to brain
ischemic stroke
type of stroke caused by rupture of a blood vessel in or around the brain, leading to bleeding
Hemorrhagic stroke
stages describing motor recovery following a stroke, characterized by the progression through flaccidity, the emergence of synergies, increasing voluntary control within and out of synergy, and the eventual return of more isolated movements.
brainstorm stages
stroke pt actively pushes with their non-paretic extremities to their paretic side, leading to lateral loss of balance.
pusher syndrome
clot-dissolving enzyme taken within a specific time window “golden hour” (3 hours) after the onset of an ischemic stroke to restore blood flow to the brain
t-PA (tissue plasminogen activator)
neurological scale to asses & document level of consciousness in pts with acute brain injury including stoke
Glasgow Coma Scale
