The Canadian Network for Mood and Anxiety Treatments (CANMAT) provides up-to-date scientific information, treatment guidelines and educational activities for healthcare professionals. We spoke to Roger McIntyre, Professor of Psychiatry and Pharmacology at the University of Toronto, at a recent congress about the latest CANMAT guidelines and how they will assist clinicians with medication selection for their patients and the impact they can have on improving patient outcomes. Here he also shares his insights on the primary challenges in innovating mental health services and how he thinks they can be tackled effectively.
