Cognitive Health and Quality of Life in Older Adults
Summary
Ageing populations worldwide face growing challenges in maintaining cognitive health, a multidimensional construct encompassing memory, executive function, attention and processing speed. Declines in these domains range from subtle subjective complaints to mild cognitive impairment (MCI) and overt dementia. Such declines exert a profound influence on physical independence, emotional well-being and social participation, key components of health-related quality of life (HRQoL). Preservation of cognitive health correlates with autonomy in activities of daily living, reduced care dependency and enhanced life satisfaction. Modifiable factors—including regular physical exercise, cognitive stimulation, balanced nutrition and social engagement—have been shown to bolster cognitive reserve, delaying or attenuating decline. Early detection through brief screening tools and biomarker-guided assessments now enables timely intervention, with implications for policy and resource allocation in primary and community care. Research efforts increasingly adopt longitudinal designs, capturing trajectories of cognitive and quality-of-life measures across diverse settings. Practical applications span from tailored cognitive training and lifestyle counselling to non-pharmacological therapies aimed at sustaining mental vitality, thereby enhancing overall well-being in later life.

Cognitive Health and Quality of Life in Older Adults publication trend
The graph below shows the total number of articles in cognitive health and quality of life in older adults across all publications each year (not limited to Nature Index journals).
Technical terms
Cognitive impairment: A reduction in one or more cognitive domains such as memory, language, attention or executive function, exceeding normal age-related changes.
Mild cognitive impairment (MCI): A prodromal stage marked by measurable deficits in cognition that do not substantially interfere with daily living activities.
Subjective cognitive decline (SCD): Self-reported perception of worsening cognitive function in the absence of objective deficits on standard tests.
Health-related quality of life (HRQoL): An individual’s perceived physical, mental and social well-being as influenced by health status and functional capacity.
Activities of daily living (ADL): Everyday tasks—such as dressing, bathing and eating—used to assess functional independence in older adults.
