FRIDAY, Feb. 28, 2014 (HealthDay News) — There may be a link between poor sleep quality and reduced gray matter in the brains of Gulf War veterans, a new study suggests.
Using MRI scans and a sleep quality assessment, researchers found that sleep disturbances among 144 Gulf War vets were associated with less gray matter in the frontal lobe — the part of the brain involved in working memory and higher-level thinking.
The findings were published Feb. 28 in the journal Sleep.
