Medical and Mental Health Risks in Autism

This cluster shows that autistic kids, teens, and adults get more sicknesses like heart problems, seizures, obesity, and mental health crises. It tells BCBAs to watch for signs early, teach safety skills before the teen years, and help families plan doctor visits. When you know these risks, you can add health goals to behavior plans and keep clients out of the hospital.

Key Findings

What 100 articles tell us

  1. Autistic children are significantly more likely to develop serious physical illnesses within the first year of diagnosis, so early medical referrals matter.
  2. Adults with profound autism often show behavioral changes — not typical pain signs — when they are in medical distress, so treat sudden behavior shifts as possible medical alerts.
  3. Autistic kids are about 76 percent more likely to have chronic pain than their peers, including headaches and body pain.
  4. Antipsychotic medications are very commonly prescribed to autistic youth, often off-label, which makes BCBA collaboration with prescribers important for monitoring side effects.
  5. Autistic females receive cancer-prevention screenings and vaccines at very low rates, pointing to a critical gap in preventive care.

Frequently Asked Questions

Common questions from BCBAs and RBTs

Look for sudden changes in behavior that do not have a clear environmental trigger. In nonverbal clients especially, things like increased SIB, aggression, or withdrawal can be a sign of pain or illness. Always rule out medical causes before adjusting a behavior plan.

Encourage families to keep up with routine checkups, vision exams, and for adolescent females, cancer-prevention screenings and vaccines. Research shows these preventive steps happen much less often for autistic individuals than they should.

Yes. BCBAs are often the professionals who spend the most time observing a client's behavior. If you notice weight gain, sedation, or new motor symptoms after a medication change, document it and share it with the prescribing doctor.

Research finds that autistic children are much more likely to experience chronic pain — including headaches and body pain — compared to typically developing peers. Adding pain screening to your routine assessment can catch problems early.

Unmanaged pain, poor sleep, and untreated medical conditions can drive or worsen problem behaviors. Addressing the health issue often reduces behavior problems faster than changing the reinforcement schedule alone.
