The cause is commonly associated with atherothrombotic occlusion of large arteries; cerebral embolism (embolic infarction); nonthrombotic occlusion of small, deep cerebral arteries (lacunar infarction); and proximal arterial stenosis with hypotension that decreases cerebral blood flow in arterial watershed zones (hemodynamic stroke). Imaging is essential to rule out intracranial hemorrhage, confirm the diagnosis, and determine the extent of stroke. Therapy is volume and time driven. Secondary prevention is critical. Carotid endarterectomy, carotid stenting, antiplatelet therapy, or anticoagulation may be indicated.
