This study seeks to determine if pregnenolone can improve symptoms of PTSD and other symptoms
that commonly occur with PTSD in Iraq/Afghanistan-era Veterans. The total study duration is
10 weeks. Eligible Veterans with PTSD will receive either pregnenolone or placebo throughout
the study duration and will complete mental and physical health assessments at each study
visit. Eligible participants will attend 6 in-person study visits and receive several short
"check-in" phone calls.
