More study needed to determine why veterans with PTSD are more at risk than othersResults of a study reported in the September issue of the Journal of the American Geriatrics Society suggest that Veterans with post-traumatic stress disorder (PTSD) have a greater risk for dementia than Veterans without PTSD, even those who suffered traumatic injuries during combat.Exposure to life threatening events, like war, can cause PTSD, and there are high rates among veterans. PSTD includes symptoms such as avoiding things or people that remind a person of the trauma, nightmares, difficulty with sleep, and mood problems."We found Veterans with PTSD had twice the chance for later being diagnosed with dementia than Veterans without PTSD," said Mark Kunik, M.D., M.P.H., a psychiatrist at the Michael E. DeBakey VA Medical Center, Texas, USA, and senior author of the article. "Although we cannot at this time determine the cause for this increased risk, it is essential to determine whether the risk of dementia c

"We found Veterans with PTSD had twice the chance for later being diagnosed with dementia than Veterans without PTSD," said Mark Kunik, M.D., M.P.H., a psychiatrist at the Michael E. DeBakey VA Medical Center, Texas, USA, and senior author of the article. "Although we cannot at this time determine the cause for this increased risk, it is essential to determine whether the risk of dementia can be reduced by effectively treating PTSD. This could have enormous implications for Veterans now returning from Iraq and Afghanistan."
"Despite the increased risk for those with PTSD, it is noteworthy that most Veterans with PTSD did not develop dementia during the period we studied," said Salah Qureshi, M.D., a staff psychiatrist and investigator with the Houston VA Center of Excellence and first author of the article."It will be important to determine which Veterans with PTSD are at greatest risk and to determine whether PTSD induced by situations other than war injury is also associated with greater risk."
