title: Neurological and developmental problems in pediatric HIV infection.
abstract: Human immunodeficiency virus type-1 (HIV-1)-associated neurologic disease, known as "HIV-1-associated progressive encephalopathy" (PE), is a common concomitant in the progression towards AIDS. PE, characterized by a triad of symptoms including impaired brain growth, progressive motor dysfunction, and loss or plateau of developmental milestones, is believed to result from both direct and indirect effects of HIV-1 infection on the central nervous system (CNS). Consequent to the hallmark systemic immune deficiency of HIV infection, the CNS becomes susceptible to opportunistic infections which add further morbidity and mortality, and may contribute either directly or indirectly to neurologic symptoms which can often mimic PE. Static encephalopathies (SE) represent fixed, nonprogressive neurologic or neurodevelopmental deficits in HIV-infected children. SE may or may not be caused by HIV infection but are often associated with such identifiable insults as prematurity, in utero exposure to toxins or infectious agents, or head trauma. Additional neurological manifestations of HIV infection are seizures, cerebrovascular complications (i.e., stroke), myelopathies, neuromuscular syndromes, and CNS complications of opportunistic infections. Neurobehavioral aberrations have also been observed in pediatric HIV infection. In addition to the neuropathogenesis, theories regarding the timing and detection of the neurological problems associated with pediatric HIV infection are discussed along with a presentation of current treatment paradigms and their rationales. The importance of identifying the numerous environmental factors, including nutritional status, that may confound the ability to discriminate between a primary or secondary role of HIV infection in the various neurological problems of HIV infection is discussed.
