Relationship between psychiatric disease and neuropsychological impairment in HIV seropositive individuals

Neuropsychological impairment and DSM-III-R Axis I psychiatric diagnoses were evaluated in a heterogenous group of HIV seropositive individuals and seronegative individuals with similar risk factors for HIV infection. Neuropsychological and psychiatric disorders were common in the HIV seropositive group, but there were no relationships between these two aspects of neuropsychiatric dysfunction in seropositive patients. Results indicate that psychiatric disorders in HIV seropositive individuals tend to predate infection and decrease over time following knowledge of seroconversion, suggesting that they are primarily a function of psychosocial factors. Neuropsychological disorders are specific to HIV seropositive patients and tend to increase over time following seroconversion, suggesting that they are due to neurological effects of HIV-infection.
