Contralateral homonymous hemianopsia
Distal posterior circulation stroke
Unilateral limb weakness Dizziness Dysarthria N/V Dizziness Horner's syndrime
Basilar artery occlusion (Middle posterior circulation)
N/V Dysphagia Nystagmus Unilateral limb weakness/ ataxia Unilateral CN V symptoms
Vertebrobasilar occlusion (Proximal posterior occlusion)
Dizziness w/ or w/o vertigo N/V Headache Gait instability Limb ataxia
Cerebellar infarction
Pure motor or pure sensory deficit
Lacunar infarction
Unilateral headache Neck pain Face pain History of migraine Other RF: HTN, large vessel arteriopathies
Carotid/ vertebral artery dissection
