Q

MCA Stroke symptoms

A

Contralateral paralysis and sensory loss in face and upper limb. Aphasia if stroke is dominant lobe (left) or hemineglect if nondominant (right side). Homonymous hemianopsia (loss of visual field on opposite side of stroke in each eye so left side has right field loss in both eyes so eyes deviate to left)
