intercerebral hemorrhage ( more common) subarachnoid hemorrhage.
What are the types of ischemic stroke?
arterial thrombotic cerebrovascular disease, cryptogenic, lacunar, embolism.
pure motor hemiplegia, pure sensory strokes, ataxic hemiparesis, sensory motor syndrome , clumsy hand syndrome are all sx of
lacunar strokes
Whwere do lacunar strokes usually occur?
secondadry to small vessel damage. They invoolve the deep perforating vessels from DM and HTN
Which areas are most commonly affected by lacunar strokes?
basal ganglia and internal capsule, where fibers anastamose
are lacunar strokes sometimes asymptomatic?
yes
If someone is experincing pure motor hemiplegia what are their symptoms?
contralteral weakness involving face-arm-leg.
Pure motor hemiplegia is a sign of a lesion where?
in the pons or internal capsule
paresthesias of the face arm and leg are indicative of a lesion wher?
thalamus and they are pure sensory strokes.
incoordination accompanied by weakness of the same limbs are called what?
ataxic hemiparesis.
ataxic hemiparesis shows a lesion where?
pons
sensory motor syndrome with sensory deficits and weakness in the face arm and leg are from lesions where?
posterior limb of hte internal capsule.
What is described as slurred speech wtih clumsy contralteral hand.
dysarthria clumsy hand syndrome.
dysarthria clumsy hand syndrome is from a lesion located where?
pontine/ brainstem lacunes.
If a patient presents with: right hemiparesis in the arms more than legs, right facial weakness in lower portion, aphasia brocas, which artery could have have a stroke in?
left sided middle cerebral artery
does brocas aphasia have full comprehension/
yes. its a nonfluent aphasia where pt can understand, but can’t express thoughts
Where is broca’s area located?
inferior frontal lobe
Where is wernicke’s area located

no, their speech is in full sentences, but it makes no sense.
what is global aphasia
