Posttraumatic stress disorder and stress-related disorders.
Posttraumatic stress disorder (PTSD) is a prevalent anxiety disorder. Symptoms present shortly after an exposure to a traumatic event, abate with time in the majority of those who initially express them, and leave a significant minority with chronic PTSD. PTSD may be treated with pharmacotherapy or psychotherapy. Treatment of the early expressions of the disorder constitutes a separate domain o...
متن کاملMolecular Neuroimaging in Posttraumatic Stress Disorder
Over the past decade, an increasing number of neuroimaging studies have provided insight into the neurobiological mechanisms of posttraumatic stress disorder (PSTD). In particular, molecular neuroimaging techniques have been employed in examining metabolic and neurochemical processes in PTSD. This article reviews molecular neuroimaging studies in PTSD and focuses on findings using three imaging...
متن کاملFunctional neuroimaging studies in posttraumatic stress disorder.
Post-traumatic stress disorder (PTSD) is a significant problem that can affect individuals who have been exposed to a traumatic event or events, such as combat, violent crime or childhood abuse. Over the past several years, neuroimaging studies of PTSD have focused on elucidating the brain circuits that mediate this disorder. In this article, we will briefly introduce some of the methods used i...
متن کاملPosttraumatic Stress Disorder Neuroimaging of Hyperaroused and Dissociative States in Posttraumatic Stress Disorder
Posttraumatic stress disorder (PTSD) patients can have very different responses to recalling traumatic memories during neuroimaging. Pilot studies in our laboratory have shown that approximately 70 per cent of patients relived their traumatic experience and showed an increase in heart rate while recalling the traumatic memory. The other 30 per cent of patients had a dissociative response, with ...
متن کاملDiagnostic potential of multimodal neuroimaging in posttraumatic stress disorder
Despite accumulating evidence of physiological abnormalities related to posttraumatic stress disorder (PTSD), the current diagnostic criteria for PTSD still rely on clinical interviews. In this study, we investigated the diagnostic potential of multimodal neuroimaging for identifying posttraumatic symptom trajectory after trauma exposure. Thirty trauma-exposed individuals and 29 trauma-unexpose...
