The nature and prevalence of memory disorder late after stroke.
This study aimed to investigate the incidence and nature of memory impairment late after stroke. Out of 193 patients between 12 to 36 months post-cerebrovascular accident contacted in a postal survey, 113 replied that they had experienced memory impairment following the stroke. Seventy of these patients were assessed on an adapted version of the Rivermead Behavioural Memory Test, Warrington's Recognition Memory Test for words and faces, and an every day memory questionnaire. The Token Test and the Benton Facial Recognition Test were also administered as measures of language and visuoperceptual processing. Thirty-five of the patients were impaired on one or more of the memory measures. Of these, 16 showed no evidence of dysphasia or visuoperceptual impairment. The 16 cases of selective memory impairment typically had mild to moderate deficits, and only three were impaired across all three tests. The results suggest that memory impairment following stroke does not necessarily involve general memory impairment. The evidence for material-specific memory deficits was much weaker.
