Fiber is a commonly recommended part of a healthy diet.

Repeated intravenous (IV) ketamine infusions significantly reduce symptom severity in individuals with chronic post-traumatic stress disorder (PTSD) and the improvement is rapid and maintained for several weeks afterwards, according to a new study.

The introduction of computer simulation to the identification of symptoms in children with attention deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioral problems, researchers suggest.

Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictable. Treatments and outcomes could potentially be improved if doctors could better predict who would develop PTSD. Now, researchers using magnetic resonance imaging (MRI) have found potential brain biomarkers of PTSD in people with traumatic brain injury (TBI).
