Clinical features

Occlusion	Symptoms
Anterior choroidal artery occlusion	Full triad of contralateral hemiplegia, hemihypesthesia, & homonymous hemianopsia Hemiparesis (most common symptom) Hemisensory loss, transient but possibly severe at onset Visual defects include homonymous upper-quadrantanopia, hemianopsia, or upper and lower-quadrant sector anopsia
Recurrent artery of Heubner occlusion	Expressive aphasia Mild hemiparesis
Anterior communicating artery occlusion	Contralateral weakness & sensory loss, mostly in lower limbs Apraxia Anosmia Possible urinary incontinence
Middle cerebral artery occlusion	Hemiparesis Hemisensory loss Hemineglect Aphasia Homonymous hemianopsia Gerstmann syndrome w/ dominant parietal lobe infarct
Anterior cerebral artery occlusion	Contralateral hemiparesis & hemisensory loss (lower limb more affected) Extrapyramidal syndromes Gait apraxia Abulia Incontinence Akinetic mutism Depression
