What Are the Common Symptoms of Post-Traumatic Stress Disorder (PTSD)?
PTSD symptoms are categorized into four main clusters, as defined by the DSM-5. These symptoms can vary in intensity and duration among individuals but must persist for over a month and interfere with daily life to meet diagnostic criteria.
Intrusion Symptoms
These symptoms involve involuntary and distressing recollections of the trauma:
- Recurrent, distressing memories of the traumatic event(s)
- Flashbacks or dissociative reactions
- Distressing dreams related to the trauma
- Intense distress from trauma triggers and cues
Avoidance Symptoms
These symptoms reflect efforts to avoid trauma reminders:
- Avoidance of thoughts, feelings, or conversations about the trauma
- Avoidance of people, places, or activities that are reminders
- Difficulty recalling important aspects of the trauma
- Diminished interest in activities once enjoyed
Negative Alterations in Cognition and Mood
These involve changes in emotional and thought patterns:
- Persistent negative emotions (e.g., fear, guilt, anger, shame)
- Negative beliefs about self, others, or the world
- Distorted self- or other-blame for the trauma
- Detachment from others or reduced interest in activities
- Inability to experience positive emotions
Alterations in Arousal and Reactivity
These symptoms reflect heightened emotional and physical responses:
- Irritability or angry outbursts
- Reckless or self-destructive behavior
- Hypervigilance
- Exaggerated startle response
- Problems with concentration
- Sleep disturbances (e.g., trouble falling or staying asleep, nightmares)
