Persistent minority stress linked to reported cognitive decline
Among 942 sexual and gender minority adults aged 50–76, persistent lifelong exposure was linked to higher odds of reported cognitive decline (adjusted odds ratio 1.50).

Limit: Cognitive decline was self-reported, not objectively measured
Edited by Boris Djordjevic · AgingResearch.News
An observational study followed 942 sexual and gender minority adults aged 50–76 in four Southern US states across three survey waves. Participants recalled stress related to their minority status across five life stages and later reported changes in their thinking and memory.
When researchers analyzed stress persistence, the range of exposures and recent exposure together, only persistence was independently linked to reported decline. Stigma in the surrounding environment, vigilance about concealing identity and severe victimization were each linked to decline; everyday direct harassment was not. Psychological distress appeared to help account for the association between cumulative stress and decline, but this result was sensitive to adjustment for initial measurements. Measures of thinking and memory remained stable over time.
Why it matters
For cognitive health in later life, the authors suggest that reducing chronic stigma through policy and structural change may matter more than addressing isolated events alone.
Caveats
The observational design and self-reported outcome cannot establish causation or objectively measured cognitive decline. The findings may not extend beyond sexual and gender minority adults aged 50–76 in the four Southern US states studied.
