“…The use of data from a group where no improvements are found will suggest that the intervention is not effective (which is the case in this work); however, analyzing the data from individuals within a group may provide insights about the individual's characteristics related to the efficacy of such intervention. Given the importance of functional ADLs, we consider that future works should compare a cognitive intervention only to an intervention combining cognitive ϩ functional activities focusing on training participants in ADLs (e.g., preparing meals) and significant relevant goals (e.g., finding personal belongings, dressing), and measure their improvement using outcomes such as the time required to perform each task, the number of errors on each task, the number and type of external help needed, or the satisfaction derived from performing those tasks (Clare, Evans, Parkinson, Woods, & Linden 2011;Zanetti et al, 2001). It is important to note that we do not suggest that interventions must be carried out according to the predefined outcome measure.…”

Objective: There is limited evidence about the efficacy of cognitive interventions for Alzheimer’s disease (AD). However, aside from the methodological quality of the studies analyzed, the methodology used in previous meta-analyses is itself a risk of bias as different types of effect sizes (ESs) were calculated and combined. This study aimed at examining the results of nonpharmacological interventions for AD with an adequate control of statistical methods and to demonstrate a different approach to meta-analysis. Method: ESs were calculated with the independent groups pre/post design. Average ESs for separate outcomes were calculated and moderator analyses were performed so as to offer an overview of the effects of bias. Results: Eighty-seven outcomes from 19 studies (n = 812) were meta-analyzed. ESs were small on average for cognitive and functional outcomes after intervention. Moderator analyses showed no effect of control of bias, although ESs were different from zero only in some circumstances (e.g., memory outcomes in randomized studies). Cognitive interventions showed no more efficacy than placebo interventions, and functional ESs were consistently low across conditions. Conclusions: cognitive interventions delivered may not be effective in AD probably due to the fact that the assumptions behind the cognitive interventions might be inadequate. Future directions include a change in the type of intervention as well as the use of outcomes other than standardized tests. Additional studies with larger sample sizes and different designs are needed to increase the power of both primary studies and meta-analyses.

“…We selected tasks and techniques where there was published evidence of memory improvement in brain injury. In short, we included training and practice in the following domains: exercises to improve motivation [32], attention [33], working memory [34], autobiographical and episodic memory [35,36,37,38] semantic memory [39] and implicit memory [40]. An adapted motivational interview was constructed for the start of the sessions [32] (that included a set of open questions regarding the actual interest of the participants in taking part in the study, expectations about possible gains to be obtained in the study, and also questions regarding the prior existence of self-initiated activities to stimulate the brain -such as crosswords, Sudoku, reading, etc.)…”

Background. Wearable cameras are a new type of intervention aimed at stimulating memory in Alzheimer's disease (AD). Such passive external memory aids have started to be considered as alternatives to both more active external aids (such as writing in diaries, journals, and timetables) and to internal cognitive strategies (such as spaced retrieval, errorless learning). Objective. In order to understand the benefits of these innovative devices for memory compensation, the present experiment examined the effectiveness of two memory training strategies: SenseCam, a wearable camera, a passive external memory aid and a memory training programme (MEMO+) created from tasks known to stimulate memory, in comparison with a control condition, a personal written diary.Method. Fifty-one patients with mild AD were randomly assigned to one of these three groups. Training lasted for six consecutive weeks, two sessions a week, one hour each, for all groups. Patients underwent a neuropsychological assessment at baseline, after treatment and at follow up (six months later). Results. Groups showed non-significant differences at baseline. After treatment and at follow up, the SenseCam group had a superior autobiographical memory (AM) performance, compared to the Memo+ and Diary groups. The SenseCam and the Memo+ groups both showed improved episodic and semantic memory, and somewhat improved executive function. Conclusion. Our results suggest that passive memory training with SenseCam is a promising alternative to traditional memory training programs to help AD patients with autobiographical memory performance.
