In this book, clinical psychologist and professor Dr. Caleb Lack introduces readers to the class of mental health problems known as the mood disorders. Covering what we know about each of the specific disorders across eight areas (DSM-IV criteria, changes expected in DSM-5, associated features, presentation differences across the lifespan, gender and cultural differences, epidemiology, etiology, and empirically supported treatments), this text is structured in an easily digestible, but still highly informative, fashion.
