Autistic people may not receive the treatment they need for likely PTSD

There is an established body of research suggesting that autistic individuals are more likely than their neurotypical counterparts to have adverse experiences like bullying or mistreatment and suffer from PTSD.

PTSD is classified as a trauma-related disorder in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5). Symptoms of PTSD include:

• Re-experiencing the trauma through flashbacks, intrusive memories and nightmares
• Suppression of these re-experiencing symptoms and avoidance of trauma reminders
• Hyperarousal
• Negative alterations in mood and cognition
• An impact on social and/or occupational functioning

According to DSM5 (Criterion A), PTSD is only diagnosable following exposure to:

• Actual or threatened death, serious injury, or sexual violence in one (or more) of the following ways:
  • Directly experiencing the traumatic event(s).
  • Witnessing, in person, the event(s) as it occurred to others.
  • Learning that the traumatic event(s) occurred to a close family member or close friend, the event(s) must have been violent or accidental.
• Experiencing repeated or extreme exposure to aversive details of the traumatic event(s) (e.g., first responders collecting human remains; police officers repeatedly exposed to details of child abuse).

However, there is much debate as to what “trauma” actually is. Traumatic events that would not fulfil the above diagnostic criteria (“non-DSM-5 traumas”) have been seen to result in post-traumatic symptoms. Non-DSM-5 traumas could include things like bullying, discrimination, and ableism – events that autistic people have an increased likelihood of experiencing.

The research findings on PTSD

This study of trauma-exposed autistic adults without co-morbid learning disabilities aims to address what events are experienced as traumatic by this population.

59 autistic adults completed online questionnaires about their experiences of stressful or traumatic events and related mental health diffculties.

It was found that autistic adults experienced a wide range of life events as traumatic, with over 40% showing probable PTSD within the last month and 64% reporting probable PTSD at some point in their lifetime.

Physical and sexual assault were the most commonly reported traumatic events that fit the DSM-5 criteria for trauma. However, many experiences that resulted in post-traumatic symptoms would not be recognised as trauma by the DSM-5. Because autistic people have an increased likelihood of experiencing non-DSM-5 traumas, this finding raises that they may not receive the help they need for likely PTSD. The likelihood of PTSD symptoms after a traumatic event was similar for DSM-5 traumas and non-DSM-5 traumas.

Bullying, “no-traumatic bereavement” (according to the DSM criteria), and traumas relating to mental health conditions were the most highly reported non-DSM-5 traumas which caused distress. Abandonment by one’s partner and stress associated with social difficulties were also reported by multiple participants as being traumatic despite not reaching the DSM-5’s “threshold” for trauma.
