 Oxford Community Stroke Project classification of stroke8

Stroke subtypeClinical features
Total anterior circulation syndrome (TACS)Unilateral motor and/or sensory deficit of at least two areas of the face, arm, and leg
Homonymous hemianopia
Higher cerebral dysfunction—for example, aphasia, neglect
Partial anterior circulation syndrome (PACS)Any two of:unilateral motor and/or sensory deficit ipsilateral hemianopia higher cerebral dysfunction
Posterior circulation syndrome(POCS)Any of:ipsilateral cranial nerve palsy with contralateral motor and/or sensory deficit bilateral motor and/or sensory deficit disorder of conjugate eye movement cerebellar dysfunction without ipsilateral long tract deficit (that is, ataxic hemiparesis)isolated homonymous visual field defect
Lacunar syndromes (LACS)
    Pure motor stroke (PMS)Unilateral pure motor deficit clearly involving two of three areas—face, arm, and leg—with the whole of any limb being involved
    Pure sensory stroke (PSS)Unilateral purely sensory symptoms ± signs involving at least two of the three areas with the whole of any limb being involved
    Ataxic hemiparesis (AH)Ipsilateral cerebellar and corticospinal tract signs with or without dysarthria in the absence of higher cerebral dysfunction or visual field deficit
    Sensory motor stroke (SMS)PMS and PSS combined—that is, unilateral motor and sensory signs in the absence of higher cerebral dysfunction or visual field deficit
