HIV-associated psychosis: a study of 20 cases. San Diego HIV Neurobehavioral Research Center Group.
OBJECTIVE
Psychosis is an uncommon but serious complication of infection with HIV. This article presents the results of a study of HIV-infected individuals with psychosis.


METHODS
The authors evaluated 20 HIV-infected men who had noniatrogenic new-onset psychosis without delirium, current substance abuse, or previous psychotic episodes. Clinical, neuropsychological, CSF, magnetic resonance imaging, and neuropathologic assessments were made. A comparison group consisting of 20 nonpsychotic HIV-infected men matched to the psychotic subjects with respect to age, race, years of education, and Centers for Disease Control HIV stage was also evaluated.


RESULTS
The psychotic patients differed from the nonpsychotic comparison subjects in having significantly higher rates of past stimulant and sedative/hypnotic abuse or dependence and, at follow-up, a significantly higher rate of mortality. They also showed a trend toward greater global neuropsychological impairment.


CONCLUSIONS
New-onset psychosis may be, at least in part, a manifestation of an HIV-associated encephalopathy.
