It's great you're looking into recent autism research! Here's some of what's new:

Researchers have identified molecular differences in autistic brains, such as fewer mGlu5 receptors. This could lead to new diagnostics and treatments. Clinicians may soon use PET scans for objective autism diagnosis.

There are also webinars highlighting the link between GI symptoms and behavior in autism. Check out the free webinar by Dr. Bradley Ferguson on April 22, 2026.

Also, Congress secured nearly $400 million in FY2026 Autism CARES Act funding! This will boost research and training.

While there aren't specific Rett syndrome updates here, keep an eye on general autism events for overlapping neurodevelopmental research.
