Posttraumatic Stress Disorder (PTSD), as defined in the DSM-V, is characterized by 5 symptoms. The last four must last longer than a month and cause significant distress:
- Exposure to trauma: death or threat of death or injury.
- Intrusive symptoms: memories, flashbacks, psychological distress, physical distress.
- Avoidance: trying not to think about the trauma, avoiding places that remind you of it.
- Negative alterations in thought and mood: amnesia, negative beliefs, distorted cognitions, lack of interest, detachment, estrangement from others, inability to experience positive emotions.
- Arousal: Irritability, angry outbursts, reckless behavior, hypervigilance, exaggerated startle, difficulty concentrating, insomnia.
