CVA Flashcards
What are risk factors for CVA?
- atherosclerosis
- heart disease
- hypertension
- diabetes/metabolic syndrome
- TIA
What does the ICA terminate into?
MCA and ACA
With an ACA stroke, which is more spared, UEs or LEs?
UEs
Locked-in syndrome occurs from a stroke to what area?
pontine lesion (basilar a)
What is locked-in syndrome?
tetraplegia, mutism, preserved consciousness and vertical eye movements/blinking, lower bulbar paralysis (V-XII)
What does a lacunar stroke look like?
contralateral hemiplegia UE/LE; no aphasia, visual field deficits rare
- results from internal capsule lesion
An internal capsule lesion causes what kind of stroke?
lacunar
You might see central (thalamic) pain in what kind of stroke?
stroke to primary visual cortex, occipital lobe (PCA syndrome)
Where is a pontine stroke?
in the brain stem in the pons (between mid brain and medulla oblongata)
What does the MCA supply?
lateral cerebral cortex
basal ganglia
large portions of internal capsule
What does the ACA supply?
anterior 2/3rds of medial cerebral cortex
What supplies the midbrain, temporal lobe, dencephalon, and posterior third of cortex?
PCA (recall thalamic pain… diencephalon)
Describe L v R stroke behaviors.
L = timid, slow, cautious, insecure R = impulsive, quick, exhibit poor judgement/safety, overestimate abilities/underestimate problems
Describe recovery stages of stroke.
1) initially flaccid/no movement
2) emerging spasticity, hyperreflexia, synergies
3) voluntary movement possible in synergies, high spasticity here
4) emerging isolated voluntary joint control
5) moving out of synergies
6) control/coordination near normal
Perceptual deficits often accompany CVA to what hemisphere/lobe?
R hemisphere, parietal lobe
