The clinical features of stroke subtypes

Stroke subtype features
lacunar infarcts (LACI) pure motor or sensory stroke, sensorimotor stroke, or ataxic hemiparesis
total anterior circulation infarcts (TACI) a combination of new higher cerebral dysfunction (e.g., dysphasia), homonymous visual field defect, and ipsilateral motor or sensory deficit of at least 2 areas of face, arm, and leg
partial anterior circulation infarcts (PACI) only 2 of 3 components of TACI; higher cerebral dysfunction alone or with motor/sensory deficit more restricted than for LACI
posterior circulation infarcts (POCI) brain stem or cerebellar dysfunction
 

Why?

Classifying the type of stroke helps determine probability of recovery, recurrent stroke and death
