ABSTRACT
Cognitive decline is a normal part of aging, but memory can be more sensitive to age than other aspects. The link between exercise and cognitive function has been demonstrated in a range of populations, including healthy middle-aged adults, healthy older adults and adults with mild cognitive impairments. A result frequently found is that older adults have greater impairments in recall or recollection than they do in familiarity or recognition judgements. This finding has been replicated using multiple methods of measurement. Using multiscale entropy analysis of electronencephalography, a recent study indicated that physically active older adults have better accuracy on both visuo-spatial attention and working memory conditions relative to their sedentary counterparts. Performance also declines on associative memory and source memory tasks. Process estimates revealed that context increased the sensitivity of recollection based memory and also the sensitivity of familiarity based memory.
