Covering a wide variety of common co-occurring mental health conditions including mood disorders, anxiety, psychosis, OCD, personality disorders, and eating disorders, this guide also explores broader issues to do with promoting positive mental health and wellbeing. Authoritative and detailed, this is an essential resource for all clinicians and professionals looking to understand and tailor their approach to mental health in autistic adults, and the need for specific methods and strategies to enhance assessment and treatment.
