Abstract: This quasi-experimental study examined the effects of a mnemonic training group on cognitive function in elderly people with cognitive impairment. Thirty subjects with mild level of cognitive impairment were recruited from nursing homes, they were randomly assigned to intervention group and control group. The intervention group received eight 1-hour sessions of mnemonic training using mnemonics over 4-week period whereas the control group performed recreational activities at the residential homes. Their cognitive functions were assessed in terms of global cognition and declarative memory by the Cantonese Mini-Mental State Examination (CMMSE), Fuld Object Memory Evaluation (FOME)-total storage, total retrieval and delayed recall respectively. There were no significant baseline differences between the intervention group and the control group regarding age, gender, marital status, length of stay, educational level, global cognition and declarative memory. It was found that the time x group interaction effect in CMMSE scores was significant (F=(2, 56)=6.16, p<0.01). Post-hoc analysis indicated there was a significant improvement from pre-test to post-test in the intervention group (p<0.017). As for declarative memory measured by FOME, there was no significant result. The present study enriched the knowledge of mnemonic training program. Mnemonic strategies were too complicated for people with early-stage dementia, when hippocampus was damaged. There were limitations for the applicability of mnemonic training program on Chinese elderly people, especially those with low educational level and lack of premorbid use of mnemonics. The standard protocol developed for the present study encourages a wider clinical application of mnemonic training program in different group of people and allows comparisons of results across studies. Future studies using the standard protocol on people with healthy elderly who are well educated, or targeting rehabilitation on more preserved function for elderly with dementia were suggested.
