title: HIV and the nervous system.
abstract: Neurological manifestations are common in HIV-infected individuals. Autopsy data suggest that the brain may be affected in as many as 80 per cent of cases. While opportunistic infections represent a major cause of neurological morbidity and mortality, there is growing evidence that HIV is itself neurotropic and can directly affect the nervous system.
