"This text examines the fads and fallacies, both past and present, that have plagued psychiatric diagnosis, treatments and research. It argues that such practices have led to an over-diagnosis of conditions such as depression, bipolar disorder, ADHD, PTSD and autism. It examines the over-treatment of psychiatric disorders with pharmaceuticals, and asks if neuroscience will actually hold the answers to the biggest questions in the field. Thoroughly updated in light of new research, this new edition addresses some of the more recent developments in psychiatry, including behavioural genetics, genome-wide association studies, and brain imaging. It looks at new advances in psychotherapies and argues for a broad biopsychosocial model. The book will inform psychiatrists, clinical psychologists, other mental health professionals, and medical students of the limits of mental health practice and the importance of adopting cautious conservatism and the principles of evidence-based practice"--.
