SummaryCognitive rehabilitation for memory deficits following strokeIt is uncertain whether cognitive rehabilitation can improve memory problems after stroke. Memory problems are a common complaint for people who have had a stroke. Neuropsychological rehabilitation, and cognitive rehabilitation in particular, may play a role in the recovery of memory functions, or in the individual's potential to adapt to the deficits. Memory rehabilitation can address both these aspects and is a standard part of rehabilitation in many settings. This review of two trials involving 18 participants found that there was little evidence to support the effectiveness of cognitive rehabilitation for memory problems after stroke and more research in this area is needed.

July 24. 2000 AbstractBackgroundMemory problems are a common cognitive complaint following stroke. Memory rehabilitation programmes either attempt to retrain lost or poor memory functions, or teach patients strategies to cope with them. ObjectivesTo determine the effectiveness of cognitive rehabilitation for memory problems following stroke. Search strategyWe searched the Cochrane Stroke Group Trials Register (last searched September 2006). In addition, we searched the following electronic databases; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2005), MEDLINE (1966 to June 2005), EMBASE (1980 to June 2005), CINAHL (1982 to June 2005), PsycINFO (1980 to July 2006), AMED (1985 to June 2005), British Nursing Index (1985 to June 2005), CAB Abstracts (1973 to May 2005) and the National Research Register (June 2006). We handsearched relevant journals and searched reference lists. Selection criteriaWe selected controlled trials of memory retraining in stroke. We excluded studies with mixed aetiology groups unless 75% or more of the participants had a stroke or separate data were available for the stroke patients. Data collection and analysisTwo review authors selected trials for inclusion, assessed quality, and extracted data. Main resultsTwo trials, involving 18 participants, were included. One study compared the effectiveness of a mnemonic strategy treatment group with a 'drill and practice' control, while the other compared the effectiveness of an imagery mnemonics programme with a 'pragmatic' memory rehabilitation control programme. Formal meta-analyses could not be performed due to a paucity of studies and lack of commonly-employed outcome measures. The results do not show any significant effect of memory rehabilitation on performance of objective memory tests, and no significant effects of treatment on subjective and observer-rated measures of memory. Authors' conclusionsThere was no evidence to support or refute the effectiveness of memory rehabilitation on functional outcomes, and objective, subjective, and observer-rated memory measures. There is a need for more robust, well-designed and better-reported trials of memory rehabilitation using common standardised outcome measures. |
