A 4-week morning light treatment reduces amygdala reactivity and clinical symptoms in adults with traumatic stress.

ABSTRACT: Trauma leads to mental health problems including posttraumatic stress disorder (PTSD), depression, and anxiety. New treatments are needed for traumatic stress that can overcome barriers to care while targeting underlying biological mechanisms of the pathology. Morning light treatment has potential as a novel intervention for traumatic stress. We conducted a randomized clinical trial testing 3 doses of a 4-week morning light treatment in people with traumatic stress to evaluate brain mechanisms underlying the treatment. Forty-six participants completed a baseline week followed by a 4-week morning light treatment (15, 30 or 60 mins each morning). Functional magnetic resonance imaging was conducted at pre- and post-treatment using an emotional faces task to probe the amygdala, based on prior
