What fibromyalgia teaches us about autism - Bruce Gillis

Many autistic children struggle with sleeplessness, exhaustion, anxiety, and sensory overload, and parents are often told it’s “just autism.” But what if some of these struggles are actually signs of pain or immune stress that kids can’t explain?In this episode, we explore what autism parents can learn from fibromyalgia research—and why those discoveries matter for children who can’t tell us when something hurts.Our guest is Dr. Bruce S. Gillis, a Harvard-trained physician and medical researcher with more than 40 years of experience studying immune dysfunction, chronic pain, and fibromyalgia. His work challenges the idea that these symptoms are purely behavioral and offers a biological framework that may help autism families better understand what their children are experiencing.What you’ll learn • Why pain in autistic children is often missed or misunderstood • How fatigue, anxiety, and sensory overload can be signs of physical distress • What fibromyalgia research reveals about whole-body conditions that affect the brain • How immune system dysfunction can change sleep, energy, and regulation • What parents can observe at home when a child can’t say “this hurts” • Why understanding biology can reduce blame, guilt, and confusionChapters00:00 – When behavior may actually be pain04:30 – Sleeplessness, fatigue, and overload in autism11:10 – What fibromyalgia research uncovered19:40 – The immune system’s role in brain symptoms28:20 – How parents can spot pain without words36:10 – What this means for autism familiesResources • Mendability: https://www.mendability.com • Dr. Gillis’s work and the FM/a Test: https://www.fmtest.com
