Background

Memory 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.

Objectives

To determine the effectiveness of cognitive rehabilitation for memory problems following stroke.

Search methods

We 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 criteria

We 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 analysis

Two review authors selected trials for inclusion, assessed quality, and extracted data.

Main results

Two 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' conclusions

There 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.

Cognitive rehabilitation for memory deficits following stroke

It 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.

背景

認知復健對於中風後的記憶障礙的恢復

記憶問題是中風後常見的認知障礙. 記憶方面的復健一方面幫忙再訓練失去或變差的記憶功能,也提供病人一些因應的對策.

目標

評估認知復健對於中風後的記憶問題的幫助

搜尋策略

我們搜尋了Cochrane Stroke Group Trials Register(搜尋至2006年9月). 此外,也搜尋了以下的電子資料庫, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2005), MEDLINE (1966到2005年6月), EMBASE (1980到2005年6月), CINAHL (1982到2005年6月), PsycINFO (1980到2006年7月), AMED (1985到2005年6月), British Nursing Index (1985到2005年6月), CAB Abstracts (1973到2005年5月) and the National Research Register (2006年6月). 我們也手動搜尋了相關的期刊及其參考資料.

選擇標準

我們選擇了中風後記憶再訓練的對照性試驗. 我們排除了有多病因的研究,除了有75%以上的病人為中風的研究或是對於中風的病人有個別的資料.

資料收集與分析

2位回顧者依收納標準來選入試驗並評估品質及摘錄數據

主要結論

2個包含18人的試驗被選入.1個試驗比較使用助記法跟訓練操作法的效用,而另1個試驗比較圖像助記法和實用記憶法的效用. 正統的metaanalyses無法執行因為研究不足和缺乏常規的結果分析. 結果顯示沒有任何記憶復健能有意義地提升病人接受客觀記憶評量的表現,也無法改善主觀和旁觀者的記憶評量.

作者結論

目前沒有證據支持或推翻記憶復健對於功能恢復,客觀,主觀或旁觀者的記憶評量的功效. 我們需要更強而有力,設計和發表良好的記憶復健研究,且要使用標準的結果分析法.

總結

認知復健對於中風後的記憶障礙的恢復:目前尚不清楚認知復健是否能改善腦中風後記憶力問題。對於那些有過中風者,記憶問題是一種常見的抱怨。神經心理和認知復健,特別是在恢復記憶功能,或個人的潛力去適應缺陷有重要的功用。記憶復健可以解決這兩方面且在很多情形這是復建的一個標準部分。本篇回顧包含兩個試驗涉及18個參與者發現幾乎沒有證據來支持認知復健對於中風後的記憶障礙恢復的有效性,在這方面需要更多的研究。
