Infections and other abnormalities associated with HIV infection.
Encephalopathy caused by direct infection of brain tissue by the human immunodeficiency virus (HIV). This condition affects patients with severe immunosuppresion more often than those whose immune function is stronger. Central nervous system HIV infection affects as many as 15% of AIDS patients, but in 1997 its incidence decreased to approx. 30% of its previous occurrence because of the effectiveness of highly active antiretroviral therapy (HAART). Central nervous system HIV infections in children tend to be more pronounced than those in adults.
