Schizophrenia is a debilitating mental illness that affects more than 21 million people worldwide. While genetics plays a part, several environmental factors can predispose someone to getting the condition. This episode of A Grey Matter features Professor John McGrath, a psychiatrist and schizophrenia researcher at the Queensland Brain Institute. He talks about smoking, vitamin D, and how common it actually is to experience hallucinations and delusions.
