Progressive cognitive impairment in human immunodeficiency virus (HIV) infection, called acquired immunodeficiency syndrome (AIDS) dementia complex (ADC), significantly influences the social prognosis of afflicted patients. The frequency and character in different stages of the infection are controversially discussed. In previous studies, differences in the selection of patients and methods of testing led to widely differing results. For these reasons, in the present prospective study on 45 HIV‐infected patients, a structured psychiatric interview (SIDAM) was conducted based on the algorithm of diagnosing dementia in DSM‐III‐R and the ICD‐10 guidelines. The psychopathological findings are expressed in syndrome scores; the results are summarized in a total score (SISCO). The interview contains the Mini‐Mental State Examination. The degree of psychosocial functioning was estimated on the global assessment of functioning, Axis V of DSM‐III‐R. In stages preceding AIDS, only slight cognitive dysfunction was found compared with age‐ and education‐matched normal controls, and this caused no relevant disturbance of psychosocial functioning. In 9 patients with manifest AIDS, dementia was diagnosed with DSM‐III‐R criteria and ICD‐10 guidelines (30% of the AIDS patients). They showed marked impairment of intellectual ability, memory, verbal ability and calculation and constructional ability and fewer cortical focal symptoms (aphasia and apraxia). Corresponding to previous studies, major cognitive dysfunction in HIV infection can be characterized as subcortical dementia.
