Lacunar strokes result from occlusion of the small, perforating arteries of the deep subcortical areas of the brain. The infarcts are generally from 2-20 mm in diameter. The most common lacunar syndromes include pure motor, pure sensory, and ataxic hemiparetic strokes. By virtue of their small size and well-defined subcortical location, lacunar infarcts do not lead to impairments in cognition, memory, speech, or level of consciousness.
