Although the COVID-19 pandemic has been shown to be detrimental to mental health, it may hold a parallel potential for positive change. Little is known about posttraumatic growth (PTG) as a potential outcome for individuals with lived experience of psychiatric disorders following trauma exposure, especially in the context of the COVID-19 pandemic....

Posttraumatic stress disorder (PTSD) is a heritable (h² = 24–71%) psychiatric illness. Copy number variation (CNV) is a form of rare genetic variation that has been implicated in the etiology of psychiatric disorders, but no large-scale investigation of CNV in PTSD has been performed. We present an association study of CNV burden and PTSD symptoms...

Chapter
There is good evidence that some pharmacological treatments can effectively reduce symptoms of some trauma-related disorders. There is more evidence for posttraumatic stress disorder (PTSD) than for other specific trauma-related disorders. It is important that practitioners are aware of this and that appropriate prescribing of drugs occurs, when in...

Article
Background Posttraumatic stress disorder (PTSD) is heritable and a potential consequence of exposure to traumatic stress. Evidence suggests that a quantitative approach to PTSD phenotype measurement and incorporation of lifetime trauma exposure (LTE) information could enhance the discovery power of PTSD genome-wide association studies (GWAS). Meth...

Article
Background: Post-traumatic stress disorder (PTSD) is a severe and debilitating condition. Several pharmacological interventions have been proposed with the aim to prevent or mitigate it.

Abstract The ICD-11 reconceptualized Posttraumatic Stress Disorder (PTSD) as a narrowly defined fear-based disorder, and introduced Complex PTSD (CPTSD) as a new diagnosis comprised of PTSD symptoms and symptoms of ‘Disturbances in Self-Organization’ (DSO) that are more reflective of general dysphoria. Previous research suggests that PTSD symptoms...
