Physical activity and enhanced fitness to improve cognitive function in older people without known cognitive impairment

Physical activity is beneficial for healthy ageing. It may also help maintain good cognitive function in older age. Aerobic activity improves cardiovascular fitness, but it is not known whether this sort of fitness is necessary for improved cognitive function.��Eleven studies of aerobic physical activity programmes for healthy people over the age of 55 years have been included in this review. Eight of these 11 studies reported that aerobic exercise interventions resulted in increased fitness of the trained group and an improvement in at least one aspect of cognitive function. The largest effects were on cognitive speed, auditory and visual attention. However, the cognitive functions which improved were not the same in each study and the majority of comparisons yielded no significant results.��The data are insufficient to show that the improvements in cognitive function which can be attributed to physical exercise are due to improvements in cardiovascular fitness.

Cognitive Impairment and Dementia: A Practical Guide to Daily Living for Family Caregivers

The Dementia Services Information and Development Centre based at St. James’s Hospital, Dublin recently launched a new booklet for family caregivers of people with dementia. The booklet has been written to provide practical information to family care-givers of people living at home with a cognitive impairment or a dementia and to help them better cope with the day-to-day choices and dilemmas they may confront.

Social support group interventions in people with dementia and mild cognitive impairment: a systematic review of the literature

Abstract Despite the large number of studies evaluating social support groups for people with dementia, there are no systematic reviews of current evidence.The aim of this study was to evaluate the effectiveness of social support group interventions for people with dementia and mild cognitive impairment.A systematic review was performed. We searched electronic databases for randomised controlled trials. Two reviewers worked independently to select trials, extract data and assess risk of bias. A total of 546 studies were identified of which two met the inclusion criteria. We were not able to pool data for further analyses, as the interventions tested in the studies meeting the inclusion criteria were too dissimilar in content.The first trial (n = 136) showed a benefit of early-stage memory loss social support groups for depression and quality of life in people with dementia.The second trial (n = 33) showed that post-treatment self-reported self-esteem was higher in the group receiving a multicomponent intervention of social support compared with that in the no intervention control group.Limited data from two studies suggest that support groups may be of psychological benefit to people with dementia by reducing depression and improving quality of life and self-esteem.These findings need to be viewed in light of the small number, small sample size and heterogeneous characteristics of current trials, indicating that it is difficult to draw any conclusions. More multicentre randomised controlled trials in social support group interventions for people with dementia are needed.������������
