tal or nursing home setting, therapy experience with a client suffering from a particular disorder, and experience within one's own family of an illness. While no geropsychologist need aspire to become medically proficient, it is imperative that we understand the symptoms, diseases, and treatments that our clients are experiencing. Rather than simply relying on explanations from attending physicians or nurses, geropsychologists need access to reference texts as a background to the medical staffs report. The most complete work to provide a thorough, technical overview of a disease or syndrome is the Principles of Geriatric Medicine and Gerontology (Hazzard, Andres, Bierman, & Blass, 1990). For quick reference, the The Merck Manual of Geriatrics (Abrams & Berkow, 1990) is helpful. Other good sources for a short overview or summary of a disease are the few texts that have been written expressly to explore the medical-mental health interface. These works often begin with a brief description of the disease, followed by a discussion of the psychological complications of that disease. While not comprehensive, the disease summaries provide a nontechnical overview. Chief among these works are the classic, Neuropsychiatric Manifestations of Physical Disease i n the Elderly (Levenson & Hall, 19811, Aging and Clinical Practice: Depression and Coexisting Disease (Robinson & Rabins, 19891, and Depression in. Neurologic Disease (Starkstein & Robinson, 1993). Self-help books that are written expressly for elders about the most common conditions they face are also good sources of accessible medical information. An excellent example of this type of work is Aging i n Good Health: A Complete, Essential Medical Guide for Older Men and Women and Their Families (Beers & Urice, 1992).These texts categorize illness in different ways and choose t o highlight particular diseases or groups of diseases. After reviewing several of these classification schema, the following grouping of disease categories seems to the be most useful when looking for information on frail elders: cardiovascular, neurologic, respiratory, endocrine, gastrointestinal, hematologic, bone and musculoskeletal, visionhearing, and renalhrinary tract. It should be noted that cancer, under this type of classification, would fall under the specific organ with which it is associated. In addition to this "organ system" approach, most geriatric texts acknowledge the need for parallel "problem-oriented" or "syndrome" categories, including such symptomatically defined syndromes as dizziness, weight loss, sleep disorders, incontinence, pain, confusion, and falls.
