Intranasal oxytocin enhances neural processing of monetary reward and loss in post-traumatic stress disorder and traumatized controls

Anhedonia is a significant clinical problem in post-traumatic stress disorder (PTSD). PTSD patients show reduced motivational approach behavior, which may underlie anhedonic symptoms. Oxytocin administration is known to increase reward sensitivity and approach behavior. We therefore investigated whether oxytocin administration affected neural responses during motivational processing in PTSD patients and trauma-exposed controls.

Intranasal Oxytocin Affects Amygdala Functional Connectivity after Trauma Script-Driven Imagery in Distressed Recently Trauma-Exposed Individuals.

Approximately 10% of trauma-exposed individuals go on to develop post-traumatic stress disorder (PTSD). Neural emotion regulation may be etiologically involved in PTSD development. Oxytocin administration early post-trauma may be a promising avenue for PTSD prevention, as intranasal oxytocin has previously been found to affect emotion regulation networks in healthy individuals and psychiatric patients.

Local availability of green and blue space and prevalence of common mental disorders in the Netherlands

Local availability of green and blue space and prevalence of common mental disorders in the Netherlands Sjerp de Vries, Margreet ten Have, Saskia van Dorsselaer, Manja van Wezep, Tia Hermans and Ron de Graaf Background Previous studies revealed a relationship between residential green space availability and health, especially mental health. Studies on blue space are scarcer and results less conclusive.

Trauma-related self-defining memories and future goals in Dissociative Identity Disorder.

This study examined the content of self-defining autobiographical memories in different identities in patients with Dissociative Identity Disorder (DID) and comparison groups of patients with PTSD, healthy controls, and DID simulators. Consistent with the DID trauma model, analyses of objective ratings showed that DID patients in trauma identities retrieved more negative and trauma-related self-defining memories than DID patients in avoidant identities.

Back to Basics : Integrating Clinical and Scientific Knowledge to Advance the Field of Trauma-Highlights of the ISTSS-2015.

The 31st Annual Meeting of the International Society for Traumatic Stress Studies (ISTSS), November 5–7, 2015, was a vibrant and stimulating conference, with many highlights from the opening on the 10th anniversary of Hurricane Katrina; the keynotes of Anke Ehlers, John Krystal, and Regina Sullivan; the vivid panel discussions with recognized leaders in the field of traumatic stress studies; inspiring and eloquent presentations by master methodologists and clinicians; and much more.

A Paradox in Individual Versus National Mental Health Vulnerability : Are Higher Resource Levels Associated With Higher Disorder Prevalence?

An earlier study (Dückers, Alisic, & Brewin, 2016) found that countries with greater social and economic resources were characterized by a higher lifetime prevalence of posttraumatic stress disorder (PTSD). Here, we present a similar analysis of national population survey data to examine this vulnerability paradox in relation to other disorders. We predicted the lifetime prevalence of any mental health disorder (i.e., anxiety, mood, substance, and externalizing disorders) in 17 countries based on trauma exposure and country vulnerability data.

Impact of new traumatic or stressful life events on pre-existing PTSD in traumatized refugees : results of a longitudinal study

Background: A significant proportion of trauma survivors experience an additional critical life event in the aftermath. These renewed experiences of traumatic and stressful life events may lead to an increase in trauma-related mental health symptoms.

Posttraumatic Stress Disorder in Young Children 3 Years Posttrauma : Prevalence and Longitudinal Predictors.

OBJECTIVE: Age-appropriate criteria for posttraumatic stress disorder (PTSD) in young children have been established. The present study investigated the long-term course of such PTSD and its predictors in young children.

Pre-event trajectories of mental health and health-related disabilities, and post-event traumatic stress symptoms and health : A 7-wave population-based study

It is unknown to what extent classes of trajectories of pre-event mental health problems (MHP) and health-related disabilities (HRD), predict post-event traumatic stress symptoms (PTSS), MHP and HRD. Aim of the present 7-wave study was to assess the predictive values using a representative sample of adult Dutch (N=4052) participating in three health-surveys in November-December 2009 (T1), 2010 (T2), 2011 (T3). In total, 2988 out of 4052 also participated in trauma-surveys in April(T4), August(T5) and December(T6) 2012 and a fourth health-survey in November-December 2012 (T7).

Performance of Complicated Grief Criteria

TO THE EDITOR: We read with interest the article by Cozza et al. on the accuracy of DSM-5 persistent complex bereavement disorder criteria (1).The study suggests that complicated grief criteria are more sensitive in detecting cases with griefrelated symptoms than persistent complex bereavement disorder or prolonged grief disorder criteria, without compromising specificity.However,we feel that the article’s findings fail to prove superiority of the complicated grief criteria set.
