PPARA and post-traumatic stress disorder: Consistently, in a cohort of Ugandan war survivors affected by PTSD, the hair levels of PEA, oleoylethanolamide (OEA), and stearoylethanolamide (SEA) were found to be decreased when compared with levels of war survivors without current or lifetime PTSD [100], thus suggesting a decreased PPAR-α signal pathway in PTSD.
