Post-traumatic stress disorder

by Professor Jonathan Bisson


Last updated: November 2015


Post-traumatic stress disorder (PTSD) was first included as a diagnosis in the Diagnostic and Statistical Manual of Mental Disorders in 1980, and since then it has become recognised as a major cause of distress and suffering following traumatic events. 


Common symptoms of PTSD include recurring recollections and dreams related to the traumatic event, avoidance and numbing, and hypervigilance. Recent reviews have consistently recommended trauma-focused psychological therapies as a first-line treatment for PTSD, although pharmacological treatments have also been found to be effective in some cases.


This module will introduce the different biological, psychological and social models of PTSD. It will also provide up-to-date information on the epidemiology of PTSD and explain how the disorder can be effectively prevented and treated.
