Assistive technology including virtual reality and augmented reality has gained interest as a novel intervention in a range of clinical settings. This technology has the potential to provide mental stimulation, a connection to autobiographical memory through reminiscence, and enhanced quality of life (QoL) to people living with dementia (PLWD) and mild cognitive impairment (MCI). In this mini-review, we examine the available evidence from studies reporting on the potential benefits of virtual and augmented reality to provide enjoyable, leisurely activities that may promote QoL and psychological well-being and facilitate social interaction. In total, 10 studies of varying study designs and durations (5 min to 6 months) using virtual (n = 9) and augmented reality (n = 1) were examined in PLWD (n = 6) and MCI (n= 3), in addition to 1 study that included participants with both conditions. Overall, the virtual experiences were enjoyed by the participants, improved their mood and apathy, and were preferred when compared with nonvirtual experiences. However, small sample sizes and variations in study design limit the generalizability of the results. Nevertheless, the use of virtual and augmented reality technology for PLWD and MCI is a novel and emerging method which may provide cognitive stimulation and improve well-being. Future research should explore the potential application of this technology to promote social interaction in both the community and aged care settings. We suggest future studies in PLWD and MCI assess the effects of more sustained use of virtual and augmented reality technology on psychological outcomes including QoL, apathy, and depressive symptoms, with the incorporation of physiological biomarker outcomes.

Nutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants:n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016. Interventions included B-vitamins,n-3 fatty acids, antioxidant vitamins and herbs. Of the B-vitamin studies, four found benefits to cognition with supplementation. The first of these B-vitamin studies, in individuals with mild cognitive impairment (n266; duration=2 years), included benefit to executive function (P=0·015) and improvements in the Mini-Mental State Examination (MMSE) among participants with baseline homocysteine above 11·3 µmol/l (P<0·001). In the same sample, the second study found cognitive benefits of B-vitamins dependent on the higher baseline plasman-3 fatty acid status. The third B-vitamin study (n900; duration=2 years) reported improved performance in immediate (P=0·046) and delayed recall (P=0·013), whereas the fourth study (n856; duration=2 years) reported slower rate of cognitive decline in the MMSE (P=0·05). One study investigating DHA treatment (n402; duration=1·5 years) revealed the slower rate of cognitive change inapoE e4non-carriers (P=0·03). As only five included studies revealed notable benefits, presently based on the specific compounds explored here, there is not compelling evidence to support the use nutraceuticals to improve cognition in the elderly. Future long-term trials of nutraceuticals should investigate interactions with lifestyle, blood biomarkers and genetic risk factors.

Objective: The present study aimed to explore how healthy food choices are translated into everyday life by exploring definitions of healthy food choices, perceptions of own food choice, and healthy food choice drivers (facilitators) and barriers.Design: An exploratory qualitative study design was employed using semi-structured face-to-face interviews. Convenience sampling was used to recruit participants. Interviews were audio-recorded, transcribed verbatim and cross-checked for consistency. Thematic analysis was used to identify patterns emerging from the data.Setting: Canberra, Australia, October 2015–March 2016.Participants: A total of twenty-three participants aged 25–60 years were interviewed. The mean age was 38 years and the mean BMI was 29·1 kg/m². All male participants (n4) were within the healthy weight range compared with 58 % of female participants, with 26 % being overweight and 16 % being obese.Results: (i) Healthy food choices are important but are not a daily priority; (ii) healthy eating information is known but can be difficult to apply into everyday life; (iii) popular diets are used in attempts to improve healthy eating; and (iv) social media inspires and connects people with healthy eating.Conclusions: Social media facilitates healthy food choices by providing access to healthy eating information. In addition to Facebook and Instagram, healthy eating blogs were highlighted as a source of nutrition information. Research should consider exploring the use of healthy eating blogs and whether these blogs can be used as a tool by dietitians to communicate procedural healthy eating information more effectively in the future.

Social isolation and sedentary behaviour are common in residential aged care facilities (also known as nursing homes or long-term care). Use of new technologies such as virtual and augmented reality are currently under investigation for their potential to provide exciting and engaging activities for older people in residential aged care facilities. However, there is limited evidence on whether these technologies can promote physical activity in a small group setting for people with cognitive impairment. Using mixed methods, we examined the use of a virtual cycling experience in a sample of 10 participants with cognitive impairment living in residential aged care facilities. In a randomised crossover design, participants engaged in a 25-minute, self-paced, facilitated seated virtual cycling experience and a time-matched seated physical activity session in groups of five. All participants completed a brief pre- and post-intervention mood questionnaire. Video analysis was used for both conditions to compare levels of environmental stimulation, apathy and engagement using both the Person–Environment Apathy Rating Scale and the Engagement of a Person with Dementia Scale. A thematic analysis of semi-structured interviews following the virtual cycling experience was also performed. No differences were observed between conditions for all outcomes except for environmental stimulation, where there was a lower response in the intervention than the control condition (p = 0.032). This was primarily driven by lower scores for the virtual cycling experience than control in physical accessibility (p = 0.012). Participants reported the virtual cycling experience to be immersive and challenging and reminisced about cycling earlier in life. The activity manager observed that the virtual cycling experience was an overall positive experience and emphasised benefits of safety screening and preparation prior to the activities. The findings of this study support the use of the virtual cycling experience as an immersive and engaging alternative to usual activities, which might encourage higher levels of physical activity in residential aged care facilities.
