- smaller anterior cerebral arteries
two of: unilateral weakness, homonymous hemianopia and higher cerebral dysfunction.
POCS (posterior circulation stroke) Fx
- vertebrobasilar arteries
cerebella/ brainstem symptoms
loss of consciousness
isolated homonymous hemianopia
LACS (lacunar circulation stroke) Fx
- arteries around thalamus, basal ganglia, internal capsule
purely motor/ sensory defect
bilateral acoustic neuroma associated with
neurofibromatosis 2
Holme-aidie pupil
