Coping strategies for memory problems in everyday life of people with cognitive impairment and older adults: A systematic review

Effects of musical mnemonics on working memory performance in cognitively unimpaired older adults and persons with amnestic mild cognitive impairment

Episodic memory (EM) and working memory (WM) are negatively affected by healthy ageing, and additional memory impairment typically occurs in clinical ageing-related conditions such as amnestic mild cognitive impairment (aMCI). Recent studies on musical mnemonics in Alzheimer's dementia (AD) showed promising results on EM performance. However, the effects of musical mnemonics on WM performance have not yet been studied in (a)MCI or AD. Particularly in (a)MCI the use of musical mnemonics may benefit the optimisation of (working) memory performance. Therefore, in the present study, we examined the effects of musical presentation of digits consisting of pre-recorded rhythms, sung unfamiliar pitch sequences, and their combinations, as compared to spoken presentation. Furthermore, musical expertise was assessed with two perceptual tests and the Self-Report Inventory of the Goldsmiths Musical Sophistication Index. Thirty-two persons with aMCI and 32 cognitively unimpaired older adults (OA) participated in this study. Confirming and extending previous findings in research on ageing, our results show a facilitating effect of rhythm in both cognitively unimpaired OA and persons with aMCI (p = .001, ηp 2 = .158). Furthermore, pitch (p = .048, ηp 2 = .062) and melody (p = .012, ηp 2 = .098) negatively affected performance in both groups. Musical expertise increased this beneficial effect of musical mnemonics (p = .021, ηp 2 = .090). Implications for the future design of music-based memorisation strategies in (a)MCI are discussed.

If deprivation worsens dementia outcomes, stimulation should improve them

It is still not known what causes Alzheimer's Disease (AD). In this period of uncertainty, an emerging literature on risk factors suggests that the concept of "stimulation" is a useful pragmatic tool both before and after diagnosis to improve cognitive health. Before diagnosis of AD, stimulation of the brain through education, exercise, and social stimulation provides fortification against later cognitive decline. After diagnosis, specific electrical stimulation of brain circuits may protect cognitive function, and non-specific stimulation through different kinds of environmental enrichment may help to compensate for cognitive decline. Pragmatic guidelines are offered here to maximise enabling stimulation (physical, cognitive, and social activity) and minimise disabling stimulation across the lifetime (e.g. stress, pollution, and poor diet). However, much deeper structural changes in society are needed to struggle against socioeconomic and environmental deprivation and the inaccessibility of education for women across the globe.

Usability of a memory aid handbook for older people with subjective cognitive impairment-An explorative pilot study

BACKGROUND

Memory problems are common in advanced age. Memory strategies can be used to manage such challenges. To assist older people facing memory problems, we conducted a pilot study to evaluate the usability of a memory aid handbook that we developed specifically for this purpose.

METHOD

A memory aid handbook with a 7-week program was developed based on a systematic review. A total of 19 older people with self-reported memory problems (mean age: 76.11 years, female: 73.68%) tested the memory aid handbook and completed the System Usability Scale (SUS), a checklist on the relevance of the strategies in the handbook, and questionnaires on daily life functioning and self-efficacy. Further, they participated in cognitive tests. In a pre-post design, within-subject differences were determined using paired t-tests.

RESULTS

The usability of the memory aid handbook scores as were high (mean SUS score: 99.21). The checklist indicated that the handbook was perceived as beneficial for confirming already established memory strategies and stimulating new ones, such as self-acceptance, visualizing and verbalizing daily routines, and asking for help. In addition, the checklist revealed that using a calendar was considered the most helpful strategies for daily living, followed closely by taking notes, having specific places for certain items and creating routines in daily life. After the 7 weeks, participants scored significantly better in the cognitive and self-efficacy tests. The exploratory nature of the study combined with the small sample size should be considered when interpreting the results.

CONCLUSION

The usability of the handbook was high, reflecting the relevance of the strategies it contains. Teaching memory strategies can be a useful, inexpensive method to foster independence among those at risk for cognitive impairment.
