Oxford community stroke project (OCSP) classification: there were no significant differences between stroke territory distributions between PSND and PSD cases ( P > 0.05). CAMCOG = Cambridge Assessment for mental and cognition; LACS = lacunar stroke; na = not available; PACS = partial anterior circulation stroke; POCS = posterior circulation stroke; TACS = total anterior circulation stroke; AIREN = relevant imaging change meets imaging criteria as specified in the National Institute of Neurological Disorders and Stroke Association/Internationale pour la Recherche et al. rsquo; Enseignement en Neurosciences (NINDS/AIREN) criteria; CAMCOG-R = Cambridge Cognitive Assessment-revised; GDS = Geriatric Depression 15 point scale; MTA = medial temporal lobe atrophy rating; MMSE = Mini-Mental State Examination; TIA = transient ischaemic attack.
