title: Acquired immune deficiency syndrome in childhood. Neurological aspects.
abstract: Central nervous system (CNS) involvement is very frequently observed in pediatric AIDS. Clinical manifestations include encephalopathy, cognitive deficits, acquired microcephaly, neurological signs, myelopathy, and peripheral neuropathy. Neurological complications can be related to opportunistic viral infections such as encephalitis, atypical aseptic meningitis, progressive multifocal leukoencephalopathy, and myelitis. Nonviral syndromes include: toxoplasmosis, cryptococcal meningitis, candidiasis, Mycobacterium tuberculosis meningitis, and Mycobacterium avium subacute encephalitis. Bacterial infections, tumors, cerebrovascular complications, and peripheral neuropathies are not frequently observed in pediatric AIDS. The most severe complications of HIV infection is encephalopathy resulting from HIV infection of brain tissue. Direct HIV invasion of the CNS has been demonstrated. Clinical features of HIV encephalopathy are classified into three categories: (1) normal neurological findings; (2) static encephalopathy; and (3) progressive encephalopathy. AIDS dementia complex can be differentiated from the predominance of behavioral and cognitive disabilities.
