This report of the Health and Human Services Department Task Force on Alzheimer's Disease addresses nine main areas in a problem-oriented approach aimed at better defining research needs and options as well as training, service, and policy issues relevant to Alzheimer's disease. Individual chapters deal with research in the areas of epidemiology, etiology and pathogenesis, diagnosis, clinical course, treatment, the family, and systems of care. Other chapters concentrate on issues related to the training of research and clinical personnel and educational materials and information dissemination for professionals and the public. Sections in each chapter contain recommendations for research, for training (research and clinical), and for information dissemination. References are listed and an extensive appendix of projects on Alzheimer's disease supported by federal programs is included. (ABB)
