Medical Experimentation in the Elderly

Participation in human experimental research constitutes a major problem for the geriatric subject. Because there is a high incidence of noncontagious disease in the elderly, they are the group most useful for the study of new therapeutic agents or procedures. However, normal aging processes, often coupled with disease of the central nervous system, render elderly persons less able to comprehend the nature and risks of such studies. These factors permit easy exploitation of geriatric subjects in medical experimentation, with possible exposure to a significant risk of serious drug reactions and unnecessary hospitalization. Recent federal regulations have given “special protections” to children, prisoners and the mentally infirm in experimental research, to guard against abuse of their human rights. A basic requirement is that informed consent be carefully obtained and documented. Such “special protections” should now be extended to geriatric subjects so that there will be no further exploitation in the course of valid clinical research.
