Attention-Deficit/Hyperactivity Disorder in adult patients with Posttraumatic stress disorder (PTSD): Is ADHD a vulnerability factor?

OBJECTIVE: There is limited evidence suggesting a link between posttraumatic stress disorder (PTSD) and Attention-Deficit/ Hyperactivity Disorder (ADHD). This study examined the association between PTSD and ADHD using retrospective and current clinical evaluations. METHOD: Twenty-five male veterans with PTSD and 22 male veterans with panic disorder were evaluated for ADHD. The data was analyzed using chi-square and student's t-tests. RESULTS: Thirty-six percent of participants with PTSD and 9% of participants with panic disorder met criteria for childhood ADHD. Twenty-eight percent of participants with PTSD and 5% of participants with panic disorder met criteria for current ADHD. CONCLUSIONS: There appears to be a significant association of PTSD with ADHD. ADHD or common predisposing factors may increase the vulnerability for developing PTSD.
