Symptoms of PTSD (post-traumatic stress disorder)

The main symptom of PTSD (post-traumatic stress disorder) is when you keep having distressing thoughts about a traumatic event or experience.

You may experience this as flashbacks, vivid or intrusive images or thoughts, and recurring dreams or nightmares.

Symptoms of PTSD in adults

Symptoms of PTSD in adults can include:

  • avoiding people or places that remind you of the event
  • not being able to fully remember the traumatic event
  • negative thoughts or beliefs about yourself and not doing the things you used to enjoy
  • problems with your relationships, such as communicating less with other people
  • feeling disconnected from yourself and the world around you (dissociation)
  • finding it difficult to control your feelings and emotions, or not experiencing emotions at all
  • changes in your mood, such as having a low mood or being more irritable or angry than usual
  • difficulty sleeping
  • feeling very anxious and looking for danger all the time (hypervigilance)
  • repeated headaches, tummy problems or pain anywhere in the body that has no physical cause

You may experience symptoms straight after the traumatic event or many months, or even years, later.

Symptoms of CPTSD (complex post-traumatic stress disorder) are largely the same as PTSD but have different causes.

Symptoms of PTSD in children

Symptoms of PTSD in children include:

  • having dreams about the traumatic event, which can then become nightmares about monsters
  • re-enacting the trauma through play – for example, using toy cars to re-enact a car crash
  • sleep problems, such as refusing to sleep on their own
  • wetting the bed, even if they did not before the traumatic event
  • losing interest in things they used to enjoy
  • talking about death or dying
  • lots of tummy aches and headaches

Causes of PTSD (post-traumatic stress disorder)

PTSD (post-traumatic stress disorder) is caused by experiencing a traumatic event such as:

  • a serious or life-threatening accident
  • physical or sexual assault
  • abuse, including childhood or domestic abuse
  • doing certain jobs, such as a police officer, paramedic or healthcare worker
  • serious health problems, such as being in intensive care
  • a difficult birth, or your baby died
  • war

You may have experienced the traumatic event yourself, seen it happen to someone else, or heard about it happening to someone you're close to.

CPTSD (complex post-traumatic stress disorder)

The types of trauma that can cause CPTSD can include child abuse or neglect, ongoing domestic violence or abuse, and repeatedly witnessing violence or abuse.
