Dr. Mary Barbera speaks with Dr. Joseph Cautilli about autism research, including cautious optimism around university-based stem cell studies and stronger evidence for early behavioral intervention. They discuss a 2023 study showing some children diagnosed as toddlers were no longer diagnosable by age five, especially with early intervention and parent-supported engagement. The conversation emphasizes that parents should not wait for a diagnosis to begin helping their child build language, adaptive skills, communication, engagement, and quality of life through fun, child-friendly strategies.
