Insomnia Potentially Linked to Dementia Risk in Seniors
Seniors with chronic insomnia face faster brain aging and a 40% higher risk of dementia, with 14% developing cognitive issues compared to 10% without insomnia, researchers said.
- On Wednesday, researchers reported that seniors with chronic insomnia had a 40% increased risk of brain decline or dementia based on brain scans and sleep assessments of nearly 3,000 people over five years.
- Chronic insomnia affected about 16% of participants, defined as trouble sleeping at least three days a week for three months or more, and researchers reported these seniors experienced faster declines in memory and thinking skills.
- The study noted that insomniacs who carry the APOE4 gene showed brain changes involving amyloid plaques and small vessels, similar to genetic risk factors, indicating different brain effects of insomnia.
- About 14% of people with chronic insomnia developed mild cognitive impairment or dementia compared with 10%, but individuals who improved sleep via medication or lifestyle changes did not see the same risks.
- Researchers cautioned the study shows an association and not direct causality, and the American Academy of Neurology advised patients to ask doctors about recommended sleep-hygiene steps like consistent bedtime and limiting caffeine.
