Right middle cerebral artery Neglect of left side; left face, arm > leg weakness; right gaze deviation; anosognosia; agitation
Anterior cerebral artery Contralateral leg weakness; abulia; occasionally can present with bilateral leg weakness
Posterior cerebral artery Contralateral homonymous hemianopsia; contralateral sensory loss
Posterior inferior cerebellar artery Vertigo, nausea, hiccups, headache, direction-changing nystagmus
Dysarthria, ipsilateral deviation of tongue
“Crossed” motor deficits: ipsilateral facial and contralateral limb/trunk numbness
Horner syndrome (ptosis, miosis, anhidrosis)
Anterior inferior cerebellar artery Ataxia; contralateral weakness/numbness; acute hearing loss
Superior cerebellar artery Ataxic gait; vertigo; nystagmus, dysarthria
