Overview of Trauma and Stressor Related Disorders
Introduction
Most psychiatric diagnoses are clustered by core symptomatology. Trauma- and stressor-related disorders are unusual because they are grouped by apparent etiology: all of these disorders develop after exposure to a traumatic or stressful event. They are often discussed in the context of Overview of Anxiety Disorders , but the trauma- and stressor-related disorders may present with dysphoria, irritability, dissociation, substance use, or insomnia in addition to (or instead of) anxiety. Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR) categorizes the following as trauma- and stressor-related disorders: Reactive attachment disorder (diagnosed only in children) Disinhibited social engagement disorder (diagnosed only in children) Posttraumatic Stress Disorder (PTSD) (PTSD) Acute Stress Disorder (ASD) None Adjustment Disorders None Prolonged grief disorder None Other specified trauma- and stressor-related disorders Acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) are similar except ASD typically begins immediately after the trauma and lasts from 3 days to 1 month, whereas PTSD may start either as a continuation of ASD or as a separate occurrence that begins a month or more after the trauma. It may also begin with delayed expression 6 months or more after the trauma. Acute and Posttraumatic Stress Disorders (ASD and PTSD) in Children and Adolescents are discussed elsewhere.
