PTSD is classified under which category of disorders in the DSM-5?

PTSD, or Post-Traumatic Stress Disorder, is classified under Trauma and Stressor-Related Disorders in the DSM-5. This categorization reflects the understanding that PTSD arises in response to exposure to traumatic events, such as violent assaults, natural disasters, or serious accidents. The focus on trauma and the associated stressors distinguishes it from other disorder categories.

The categorization highlights the specific symptoms and experiences that are characteristic of PTSD, including intrusive memories, avoidance behaviors, negative alterations in cognition and mood, and heightened arousal. These features are directly related to the individual's exposure to trauma rather than stemming from underlying personality traits, anxiety or depressive disorders, which have different criteria and underlying mechanisms. This classification helps clinicians in diagnosis and treatment planning by framing PTSD within the context of trauma-related experiences.
