Science News About Post-Traumatic Stress Disorder

Using a molecular method likely to become widely adopted by the field, researchers have discovered brain circuitry essential for alertness – and for brain states more generally.

Using brain imaging to track the effects of treatment of post-traumatic stress disorder (PTSD), scientists have identified a brain circuit on which a frequently used and effective psychotherapy (prolonged exposure) acts to quell symptoms. The findings help explain why the neural circuit identified is a promising target for additional treatment development, including brain stimulation therapies.

By carefully tracking 5,000 people after they have experienced a traumatic event, a just-launched NIMH-funded study aims to provide a finely detailed map of the array of factors that play a role in the development of mental disorders that occur in the wake of trauma.

A video game that implicitly taught combat vets that threatening stimuli are irrelevant to performing their task reduced their PTSD symptoms.

Girls in public housing benefited emotionally from a move to a better neighborhood while boys fared worse than if they’d stayed in the poor neighborhood. Rates of depression and conduct disorder markedly increased in boys and decreased in girls. Boys also experienced significantly increased rates of post-traumatic stress disorder (PTSD), complicating housing policy decision-making.
