The nature of subjective cognitive complaints of older adults

Abstract

The current study investigated the nature of subjective cognitive complaints of older adults in relation to a broad array of individual cognitive functions known to decline with age. A 60-item questionnaire was developed to examine: (1) whether older adults experience problems with these cognitive functions (problems with cognition); (2) the extent to which these problems have changed over time (changes in cognition); and (3) whether these cognitive decrements interfere with their daily functioning (difficulties with cognition). The cognitive functions examined were attention, processing speed, working memory, executive function, and memory. One hundred eight-two community-dwelling adults (aged 65-92 years) completed the questionnaire. While participants reported problems with, and changes in, each cognitive function, working memory was recorded as most problematic and demonstrated the most change. Yet, although older adults experience problems with cognition and report changes in cognitive functioning over time, these did not necessarily produce difficulties in daily life. This points to the existence of support mechanisms that may assist older adults in cognitively demanding situations.
