Post-Traumatic Stress Disorder (NIMH)

This plain-language resource from the National Institute of Mental Health explains post-traumatic stress disorder (PTSD), who may develop it, and how symptoms can affect daily life. It describes recurring memories, avoidance, feeling constantly on guard, and changes in thoughts and mood. Information about children and teens explains how their reactions to trauma may differ from those of adults. It also discusses factors that can increase risk or support resilience, along with treatment options such as psychotherapy and medication. Practical suggestions address managing symptoms, finding professional help, and supporting a loved one with PTSD. The information is useful for individuals affected by trauma, family members, caregivers, and others seeking a basic understanding of PTSD.
