This study investigates the relationship between mindfulness, meditation, cognition and stress in people with Alzheimer's disease (AD), dementia, mild cognitive impairment and subjective cognitive decline. Accordingly, we explore how the use of meditation as a behavioural intervention can reduce stress and enhance cognition, which in turn ameliorates some dementia symptoms. A narrative review of the literature was conducted with any studies using meditation as an intervention for dementia or dementia-related memory conditions meeting inclusion criteria. Studies where moving meditation was the main intervention were excluded due to the possible confounding of exercise. Ten papers were identified and reviewed. There was a broad use of measures across all studies, with cognitive assessment, quality of life and perceived stress being the most common. Three studies used functional magnetic resonance imaging to measure functional changes to brain regions during meditation. The interventions fell into the following three categories: mindfulness, most commonly mindfulness-based stress reduction (six studies); Kirtan Kriya meditation (three studies); and mindfulness-based Alzheimer's stimulation (one study). Three of these studies were randomised controlled trials. All studies reported significant findings or trends towards significance in a broad range of measures, including a reduction of cognitive decline, reduction in perceived stress, increase in quality of life, as well as increases in functional connectivity, percent volume brain change and cerebral blood flow in areas of the cortex. Limitations and directions for future studies on meditation-based treatment for AD and stress management are suggested.
ABSTRACT Recent interest in interactive video game technology (IVGT) has spurred the notion that exercise from this technology may have meaningful physiological and psychological benefits for children and adolescents. The purpose of this study was to examine the short-term psychological effects of interactive video game exercise in young adults and whether IVGT participation was capable of improving mood as has been shown for traditional forms of exercise. In addition, we were interested in comparing both actual physical exercise output and perceived exertion of that output across the exercise conditions. One-hundred and sixty-eight college students were assigned to one of three 30-minute conditions: (1) interactive video game cycle ergometer exercise, (2) regular cycle ergometer exercise, or (3) a video game-only control condition. Positive and negative mood (PANAS; Watson, Clark, & Tellegen, 1988) was assessed before and twice-after experimental conditions, and measures of actual and perceived physical exertion were collected at five-minute intervals across exercise conditions. Participants in the video-game control had higher post-activity negative affect immediately and 10-minutes post activity than either exercise group. In addition, exercise condition participants had higher positive mood at 10-minutes post activity compared to the video game control participants. Results do not support IVGT mood benefits over other forms of exercise, but do support immediate affective benefits of exercise compared to sedentary activity. It is concluded that while there is potential for interactive video-game based applications to elicit affective benefits, there is a need to examine circumstances under which these benefits are most likely to occur.
