Stroke subtypeClinical features
Total anterior circulation infarct (TACI)Combination of new higher cerebral dysfunction (e.g., dysphasia, dyscalculia, visual-spatial disorder); homonymous visual field defect and ipsilateral motor and/or sensory defect involving two areas of the face, arm, or leg
Lacunar infarct (LACI)Pure motor or pure sensory symptoms, sensorimotor stroke, or ataxic hemiparesis; face-arm and arm-leg syndromes included
Partial anterior circulation infarct (PACI)Patients with only two of three TACI components, with higher cerebral dysfunction alone, or with a motor/sensory deficit more restricted than those classified as LACI (e.g., confined to one limb or to face and hand, but not the whole arm)
Posterior circulation infarct (POCI)Any one of the following: ipsilateral cranial nerve palsy with contralateral motor and/or sensory deficit; bilateral motor and/or sensory deficit; disorder of conjugate gaze; cerebellar dysfunction without ataxic hemiparesis; isolated homonymous visual field defect
