The Gale Encyclopedia of Mental Disor ders provides a good overview of mental illness, psychotherapy, and other treatments. It includes both traditional and alternative therapies.

Entries for disorders include a definition, description, causes and symptoms, demographics, diagnosis, treatments, prognosis, and prevention. Those for medications contain the definition, purpose, description, recommended dosage, precautions, side effects, and interactions. Entries for herbs and supplements have a leaf icon next to the heading. All entries have a resource list of print and electronic sources and organizations to contact. One hundred black-and-white photographs and charts illustrate the text. A color photo gallery repeated in both volumes has enhanced versions of some of the photographs. There are ample cross-references, making it easy to locate drugs, which are entered by generic name. Boxes with definitions of key terms help readers understand the material. A full glossary is at the end of volume 2. Users will find a symptom list here also. This list demonstrates patterns that are linked to various disorders.
