Anterior Circulation
Anterior Cerebral Artery (ACA)
Signs and Symptoms:
- Contralateral sensory and motor symptoms in the lower extremity (sparing hands/face)
- Left sided lesion: akinetic mutism, transcortical motor aphasia
- Right sided lesion: Confusion, motor hemineglect
Middle Cerebral Artery (MCA)
Signs and Symptoms:
- Hemiparesis, facial plegia, sensory loss contralateral to affected cortex
- Motor deficits found more commonly in face and upper extremity than lower extremity
- Dominant hemisphere involved: aphasia
- Nondominant hemisphere involved: inattention, neglect, dysarthria without aphasia
- Homonymous hemianopsia and gaze preference toward side of infarct may also be seen
Posterior circulation
- Blood supply via the vertebral vertebral artery
- Branches include, Basilar artery, PCA and PICA
Signs and Symptoms:
- Crossed neuro deficits (i.e., ipsilateral CN deficits w/ contralateral motor weakness)
- Multiple, simultaneous complaints are the rule
- 5 Ds: Dizziness (Vertigo), Dysarthria, Dystaxia, Diplopia, Dysphagia
- Isolated events are not attributable to vertebral occlusive disease (e.g. isolated lightheadedness, vertigo, transient ALOC, drop attacks)
Basilar artery
Signs and Symptoms:
- Quadriplegia, coma, locked-in syndrome
Posterior Cerebral Artery (PCA)
Signs and Symptoms:
- Unilateral headache (most common presenting complaint)
- Visual field defects (contralateral homonymous hemianopsia, unilateral blindness)
- Motor function is typically minimally affected
Posteroinferior Cerebellar Artery (PICA)
Signs and Symptoms:
- Vertigo, gait instability, limb ataxia, Headache, dysarthria, Nausea and Vomitting, Cranial Nerve abnormalities
