What If Autism Isn’t Always Lifelong? A Scientist-Mom Shares Autism Science and Hope | Dr. Theresa Lyons

What if the story you’ve heard about autism is incomplete—and changing? On this episode of The Brainy Moms Podcast, Dr. Amy and Sandy dive into the science with Dr. Theresa Lyons, an Ivy League-trained researcher and autism parent who translates complex studies into clear, practical steps. Our conversation challenges the “lifelong and fixed” narrative about autism, explores why some children no longer meet diagnostic criteria over time, and shows how a health-first approach might unlock progress in speech, behavior, and learning.

We talk about digestive health and constipation. We discuss the FRAT test and why a child can have “normal” blood folate while the brain is still starving for it. That’s where folinic acid (leucovorin) comes in, supported by multiple trials showing benefits in speech, social connection, and motor control, with manageable side effects and thoughtful dosing.

We also tackle hot-button topics with nuance: vaccines, detox capacity, glutathione, and acetaminophen. Two kids can face the same exposures and have very different outcomes based on genetics, immune status, and liver function. And we address the “autism cure” debate with care—respecting identity while refusing to accept avoidable pain, insomnia, or self-injury as inevitable.

This conversation gives you a roadmap grounded in both evidence and empathy. It’s outside the scope of what mainstream media talks about. It might ruffle a few feathers. But we’re okay with that. At The Brainy Moms, we like to hear from lots of voices and we like to consider all possibilities. It challenges us and it challenges you. Join us!
