Tsapanou A, et al. - This cross-sectional design from two studies of older adults—the WHICAP (the United States) and the HELIAD (Greece)—explored the link between sleep and subjective cognitive decline in cognitively healthy elderly adults. The study sample consisted of 1,576 WHICAP and 1,456 HELIAD members who did not have mild cognitive impairment, dementia, or severe depression/anxiety. Using the Sleep Scale from the Medical Outcomes Study, sleep problems were estimated. Except orientation for the WHICAP, sleep problems were related to complaints in all the cognitive subcategories. Findings revealed that sleep disturbance may be accompanied by subjective cognitive impairment at any given level of objective cognition. The outcomes have implications for the correlates and potential etiology of subjective cognitive decline, which, the investigators recommended, should be considered in the assessment and treatment of older adults with cognitive complaints.
