More and more adults realize they have lived with an undiagnosed developmental condition, while most information and support focus on children. This leaves many adults confused and perplexed. The "Adolescent and Adult Neuro-Diversity Handbook" is a helpful reference guide for the full range of developmental conditions as they affect adolescents and adults. Each chapter focuses on a different condition, describing its history, causes and characteristics, implications for the individual, diagnosis and assessment, treatments and approaches, as well as strategies for providing support and self-support. A wide range of conditions is covered, including Autism Spectrum Disorders, Dyslexia, Dyspraxia, ADHD, OCD, Tics, and Anxiety Disorders. The "Adolescent and Adult Neuro-Diversity Handbook" is an invaluable resource for health and social care professionals, as well as individuals who feel they may be living with an undiagnosed developmental condition.
