Research suggests that clinical management of cognitive impairment can occur through interventions targeting lifestyle factors, such as physical exercise and sleep quality. The present study examined the associations among lifestyle factors (exercise and sleep quality), cognition, and functional capacity in older adults (ages 56-94) who completed an outpatient neuropsychological evaluation (N = 356). Exercise habits and sleep quality were accessed using a self-report questionnaire and a clinical interview. Cognitive functioning was assessed using the Dementia Rating Scale-2 (DRS-2). Functional capacity was measured by the Texas Functional Living Scale (TFLS). Results indicated that physical exercise and sleep quality were positively associated with better cognitive functioning and functional capacity. Further research is needed to elucidate the relationship between lifestyle factors, cognition, and functional capacity in older adults.
