AIDS and the geriatrician.

Ten percent of acquired immune deficiency syndrome (AIDS) cases are in persons over 50 years of age with 25% of these cases in persons over 60, and 4% in persons over 70 years of age. If the present age distribution holds, there will be 27,000 AIDS cases in persons over 50, and 1100 cases in persons over 70 years of age, by 1991. Older persons are more likely to acquire AIDS through blood transfusions than to homosexual exposure or drug abuse. Changes in the management of blood products will benefit older persons. The nearly 1 million elderly homosexual men, who have been sheltered from the virus by their pattern of sexual activity, will face greater risks as the prevalence of the virus and the age of the carriers increases. The underappreciated neurological consequences of human T-cell lymphotrophic virus type III (HTLV-III) infection, subacute encephalitis, vacuolar myelopathy, and psychiatric disorders will be of particular interest to geriatricians who are often consulted to evaluate neurological dysfunction. Geriatricians will need to become familiar with the spectrum of HTLV-III infection and prepared to counsel patients and extended-care facilities.
