The National Institute on Aging (NIA) has historically been concerned with the protection of human subjects. In July 1977, the NIA sponsored a meeting to update and supplement guide lines for protecting those participating in Federal research pro jects. Although the basic guidelines had been in effect since 1966, it had been neglected to include the elderly as a vulnerable population. In November 1981, the NIA organized a conference on the ethical and legal issues related to informed consent in senile dementia cases. The present volume offers the latest and best thinking on Alzheimer's Dementia to have emerged from the dialog that was first embarked upon at the NIA meeting. Indeed, the issues and concerns it treats now seem even more relevant than they appeared historically because of the vastly greater awareness in the community of the entire spectrum of problems Alzheimer's disease confronts us all with. Our interest and concern is both humanitarian and self serving. Clearly older people must be protected from in appropriate research and careful attention must be paid to the circumstances under which research is conducted on those older persons who have given anything less than full consent. It is equally necessary, however, for the research enterprise to be protected so that today's elderly and those of the future can benefit from the fruits of research.
