Q

supplies?

stroke sx?

A

posterior cerebral a.

supplies – occipital lobe, medial portions of parietal and temporal lobes, anterior & posterior midbrain, crus cerebri, posterior thalamus

stroke sx - if unilateral: blindness in the visual field contralateral to the affected side, alexia (left side).

if bilateral as with “top of the basilar” occlusion: bilateral blindness, memory loss, somatosensory loss, coma & death
