Defining psychosis versus schizophrenia

New research from the Canadian Medical Association Journal has found that more people aged 14-20 are being diagnosed with psychotic disorders, including schizophrenia, than previous generations. We talk to study co-author Dr. Marco Solmi about his findings, and some of the possible reasons behind it. Plus, psychiatrist Dr. Oyedeji Ayonrinde on why early intervention matters, and why cannabis use can't be ignored as a potential factor in this rise.
