Brain Regions of PTSD Patients Show Differences During Fear Responses
Contact: Sarah Avery Phone: 919-660-1306 Email: sarah.avery@duke.edu https://www.dukemedicine.org EMBARGOED FOR RELEASE until 10am (ET) on Tuesday, Dec. 15, 2015 DURHAM, N.C. -- Regions of the brain function differently among people with post-traumatic stress disorder, causing them to generalize non-threatening events as if they were the original trauma, according to new research from Duke Medicine and the Durham VA Medical Center.

Head injuries can alter hundreds of genes and lead to serious brain diseases, UCLA biologists report
Head injuries can harm hundreds of genes in the brain in a way that increases people ’s risk for a wide range of neurological and psychiatric disorders, UCLA life scientists report.The researchers identified for the first time master genes that they believe control hundreds of other genes which are linked to Alzheimer ’s disease, Parkinson’s disease, post-traumatic stress disorder, stroke, attention deficit hyperactivity disorder, autism, depression, schizophrenia and other disorders.Knowing what the master genes are could give scientists targets for new pharmaceuticals to treat brain diseases. Eventually, scientists...
