It goes beyond a descriptive overview of clinical disorders to provide a critical appreciation of the multifaceted aspects of mental illness. Each disorder is clearly and succinctly explained with the support of case studies. These examples are then used to introduce students to the debates surrounding current research, the biology of abnormal disorders and standards of treatment. The bridge between the biological elements of brain functioning and the psychological mechanisms that are responsible for coping and adjustment is thoroughly explored. This valuable consideration of the range of elements involved in the diagnosis and treatment of clinical disorders gives students a broad and critical understanding of this complex and fascinating field.
