Perceived Stress and Cognitive Decline in Different Cognitive Domains in a Cohort of Older African Americans

Topic: Risk, prevention and care in population studies
Background Research indicates that stress is linked to cognitive dysfunction. However, few community-based studies have explored the relationship between perceived stress and cognitive decline, and fewer still have utilized cognitive domains rather than a global measure of cognition. Objective We examined the relation between perceived stress and the rate of decline in different cognitive domains. Methods Participants were older African Americans without dementia from the Minority Aging Research Study (MARS; N = 467, mean age: 73 years, SD: 6.1 years). A battery of 19 cognitive tests was administered at baseline and at annual intervals for up to 9 years (mean follow-up: 4 years), from which composite measures of global cognitive function and five specific cognitive domains were derived. The four-item Cohen's Perceived Stress Scale (PSS) was also administered at baseline. Results In linear mixed-effects models adjusted for age, sex, education, and vascular risk factors, higher perceived stress was related to faster declines in global cognition (β = -0.019; SE: 0.008; t (1951) = -2.46), episodic memory (β = -0.022; SE: 0.011; t (1954) = -1.99), and visuospatial ability (β = -0.021; SE: 0.009; t (1939) = -2.38) all p Conclusions Results indicate that older African Americans with higher levels of perceived stress have more rapid declines in global cognition than those with lower levels, most notably for episodic memory and visuospatial ability.

Key findings
- Background Research indicates that stress is linked to cognitive dysfunction.
- Results In linear mixed-effects models adjusted for age, sex, education, and vascular risk factors, higher perceived stress was related to faster declines in global cognition (β = -0.019; SE: 0.008; t (1951) = -2.46), episodic memory (β = -0.022; SE: 0.011; t (1954) = -1.99), and visuospatial ability (β = -0.021; SE: 0.009; t (1939) = -2.38) all p < 0.05.
Why it matters
In this group of older African Americans without dementia, higher perceived stress at the start was linked to faster decline in global cognition, episodic memory and visuospatial ability over up to 9 years. This identifies stress as a possible factor in cognitive decline but does not test any treatment or prevention.
