In the present \nstudy, we analyzed data from 134 patients with AIDS and \n105 HIV\u2212 controls using a recently developed analytical \nprocedure. The results revealed that, by and large, the \ntest variables shared a significant amount of variance \nrelated to disease status. Hence the AIDS-related influences \non cognition are shared and thus cannot be considered independent. \nTwo tests, Digit Symbol Substitution, and the primacy measure \nof verbal free recall, had a direct relationship with the \ngroup variable (AIDS <jats:italic>vs.<\/jats:italic> controls). These results \nsuggest that a single factor is sufficient to account for \na large proportion of the AIDS-related variance on a wide \nvariety of neuropsychological tests.
