CHICAGO — Dementia prevalence rates are slightly lower for LGB older adults than their straight counterparts, new research has found, although the sample groups did not align exactly on age.
Rates for Alzheimer’s disease and dementia in the general population for those 65 and older is about 10 percent; prevalence was 7.4 percent for LGB adults in a recent study composed of participants 60 and older.
The findings, presented this summer at the Alzheimer’s Association International Conference, are said to be the first on dementia prevalence for LGB older adults. They were announced in a press release.
Researchers from University of California, San Francisco and Kaiser Permanente Division of Research, Oakland, Calif., examined the prevalence of dementia among 3,718 sexual minority adults age 60 and up who participated in the Kaiser Permanente Research Program on Genes, Environment and Health. Dementia diagnoses were collected from medical records.
The findings were gleaned over a nine-year period of follow-up. According to the researchers, significant rates of depression, hypertension, stroke and cardiovascular disease in the study population may be contributing factors to the level of dementia.
