Post-Traumatic Stress Disorder is a persistent condition of autonomic hyperarousal following traumatic event(s) that may last months or years. Sounds, smells, images, memories, and associations with traumatic events can trigger severe flashbacks, nightmares, and frightening memories of the trauma. Avoidance of situations that bring back memories of traumatic events, hypervigilance, anxiety, and depressed mood can rob affected individuals of their quality of life. Treatment includes trauma-informed psychotherapy as well as medications to manage symptoms.
