stroke/cva

acute loss of function due to poor circulation (symptoms >24 hr)

Ischemic cva

most common (80%), a clot blocks or impairs blood flow.

hemorrhagic cva

blood vessel ruptures (intracerebral, subarachnoid, AVM)

stroke statistics

most common neuro for PT, 1# for long term disability, 5th for death, higher in african american groups, risk doubles after 65

atherosclerosis

primary factor for CVA, due to plaque build up

risk factors for CVA

HTN 70%, heart disease, lifestyle, genetics.

atherothrombotic stroke

give clot desolving enzymes and t-PA must be given in 3-4.5 hrs

BEFAST

balance issues, eye loss, face uneven, arm weakness, speech issues, call 911

cerebral edema

starts within minutes, peaks 3-4 days, subsides in 2-3 weeks

cerebral edema signs

decreased LOC, wide BP, increased, HR, vomiting, unreactive pupils,

transient ischemic attack (TIA)

temporary interruption of blood supply, symptoms < 24hr,

anterior cerebral artery

affects primary motor/sensory cortex, corpus callosum, posteromedial frontal gyrus

anterior cerebral artery symptoms

contra hemi LE, contra sensory LE, urinary incontinence, imitation and B tasks

middle cerebral artery

werenick’s and brocas area, primary sensory/motor cortex

middle cerebral artery signs

contra spastic hemi para/sensory UE and face, broca’s aphasia, wernicke’s aphasia, or both, perceptual deficits

internal carotid artery

supplies middle and anterior artery, damage has edema

posterior cerebral artery

contra sensory, pain, face blindness, visual impairments, amnesia
