Intravenous drug abusers (IVDAs) represent an increasing proportion of the HIV epidemic. Forty-three IVDA's (22 HIV-negative, 21 HIV-positive) were studied using the Mattis Dementia Rating Scale (DRS). All subjects had used intravenous heroin, but reported that they were drug-free at the time of testing. HIV-positive subjects were predominantly symptomatic and were dichotomized into AIDS and non-AIDS groups. All subjects with abnormal DRS scores were HIV-positive (57% of all HIV-positives). All HIV-negative subjects had normal DRS scores while 43% of the positive group obtained such scores. The DRS reliably identifies neuropsychological impairment, and may be a useful screening tool in this population

In view of the evidence that patients with human immunodeficiency virus infection experience reactive depression and anxiety, it is important to determine whether these factors might account for some of the cognitive deficiencies observed in this group, as is often the case in psychiatric populations. An extensive battery of cognitive, personality, and attention tests was administered to 26 patients who tested positive for the human immunodeficiency virus. In this group were patients who demonstrated no symptoms, patients who had acquired immunodeficiency syndrome-related complex, and patients who had acquired immunodeficiency syndrome. Pearson Product Moment correlations were computed between scores on the three types of measures. The results of this correlational study suggest that cognitive decline in patients infected with human immunodeficiency virus is independent of mood and attentional changes
