PTSD Increases Risk of Dementia in Veterans
July 20, 2009
According to a new study veterans diagnosed with Post-Traumatic Stress Disorder (PTSD) have a significantly higher risk of developing dementia compared to those veterans without PTSD.
Scientists from the University of California-San Francisco reported the findings at the recent meeting of the International Conference on Alzheimer’s disease in Vienna. Their findings indicated veterans with a diagnosis of PTSD had a 10.6% rate of developing dementia over a seven year follow-up while those veterans without PTSD had a 6.6% rate.
The findings indicate that disorders such as PTSD, depression, and chronic anxiety may predispose the brain to vulnerability for dementia. Interestingly, PTSD has been related to dysfunction in the hippocampus, the critical region of disease for Alzheimer’s.
