In this episode, Dr. Puder is joined by Dr. Liam Browning and Dr. Nicholas Fabiano to explore the complex genetic and environmental factors that contribute to schizophrenia. They unpack how heritability is measured, what twin and genome-wide association studies reveal, and why the "missing heritability" problem matters for our understanding of mental illness.
The discussion also covers how prenatal factors, childhood trauma, cannabis use, and social adversity increase risk and how modern neuroscience reframes schizophrenia as a disorder of brain connectivity rather than a single genetic disease.
