In response to a listener's call about her autistic son, Dr. Sanjay Gupta invited leading autism researcher Dr. Matthew Lerner, Director of the Social Connections and Treatment Lab at the A.J. Drexel Autism Institute, to break down how our understanding of autism has changed, what it means to be “on the spectrum” and why diagnoses are on the rise. The conversation continues next Tuesday on Paging Dr. Gupta, where Sanjay explores what growing up and transitioning into adulthood really looks like for autistic people.
