If your child with autism struggles with anxiety, OCD behaviors, meltdowns at transitions, fear of other children, or constant hyperactivity, you are not dealing with separate psychiatric conditions. You are dealing with a single physiological problem: the autonomic nervous system is not working correctly, and it is flooding the body with fight-or-flight hormones.
Children with autism have ANS damage that impairs blood pressure to the brain. When oxygen delivery falls, the brain releases norepinephrine to boost pressure — but norepinephrine is the fight-or-flight hormone. The result is a child in near-constant physiological panic. The response is not voluntary. They cannot control it. This is why these children cannot simply be calmed down during a meltdown — the cause is physiological, not behavioral.
The norepinephrine release produces: aggression and transition meltdowns, anxiety and panic, OCD rituals, stimming, elopement, self-injurious behavior, and social fear.
A 9-year-old girl with autism presented with intense anxiety, extreme OCD (every door in the house had to remain closed — any open door triggered screaming), hyperactivity, major transition issues, and minimal verbal communication. After starting the basic protocol, she showed improved alertness and eye contact but anxiety and OCD remained. After switching from inulin to rifaximin: four months later tantrums reduced and OCD less intense; nine months later totally comfortable around other children, tolerating fire drills, no longer concerned with doors.
This is the consistent pattern when the underlying gut-brain mechanism is properly addressed.
As inflammation falls through inulin or rifaximin, olive oil, and fish oil, the autonomic nervous system begins to repair itself. As ANS function improves, brain blood pressure normalizes. As brain blood pressure normalizes, the norepinephrine release that is driving anxiety, OCD, aggression, and repetitive behaviors diminishes. Dr. Nemechek notes he does not specifically treat anxiety or OCD in these children — he has not encountered cases where it did not resolve as the underlying physiology recovered.
