AIDS dementia complex in the elderly. Diagnosis and management.
Ten percent of acquired immunodeficiency syndrome cases are reported in people 50 years of age or older. These older people have been infected with the human immunodeficiency virus primarily through homosexual contact, heterosexual contact or blood transfusion. AIDS in the elderly can be described as the new great imitator, often manifesting as an undetected dementia. This article focuses on the diagnosis and management of the AIDS dementia complex, a subcortical dementia with subtle and variable manifestations. The pathogenesis of AIDS dementia complex is not well understood; however, studies have shown that two-thirds of patients with AIDS exhibit overt dementia, and less than 10 percent of the brains of AIDS patients are found to be normal upon post-mortem examination. Clinical features of AIDS dementia complex include impairment in cognitive, motor and behavioral function. Since the primary care practitioner is the first line of defense in controlling the AIDS epidemic, including AIDS in the differential diagnosis for dementia is imperative.
