Former soldiers with post-traumatic stress disorder have a greater risk of developing dementia than those without the disorder, according to US researchers.
The study included 10,481 veterans at least 65 years of age, of which 36.4 per cent had PTSD.
The researchers found 18.3 per cent of those with the disorder also had dementia, compared to 9.4 per cent of those without PTSD.
Writing in the Journal of the American Geriatrics Society, the authors said: “It is essential to determine whether the risk of dementia can be reduced by effectively treating PTSD.”
