Human immunodeficiency virus and the central nervous system.

Area of Science:

• Neuroscience
• Virology
• Immunology

Background:

• Human immunodeficiency virus (HIV) infection impacts millions globally, affecting both the immune system and the central nervous system.
• HIV's neurotropic nature leads to significant brain pathology and impaired cognitive function.
• While effective, highly active antiretroviral therapy (HAART) has limitations in fully preventing or treating HIV-associated neurological complications.

Purpose of the Study:

• To review the pathogenesis of HIV-induced central nervous system (CNS) disease.
• To describe the pathological and clinical effects of HIV infection within the brain.
• To discuss controversies and challenges in using HAART for preventing and treating HIV-related CNS dysfunction.

Main Methods:

• Literature review of pathogenesis, pathology, and clinical effects of HIV in the CNS.
• Analysis of the impact of highly active antiretroviral therapy (HAART) on HIV-associated neurocognitive disorders.
• Examination of current controversies and challenges in managing HIV CNS disease.

Main Results:

• HIV infection of the brain causes substantial pathology and functional impairment.
• HAART has decreased the severity and prevalence of HIV-associated neurocognitive disorders.
• Despite HAART, significant morbidity and mortality persist due to HIV's effects on the nervous system.

Conclusions:

• HIV CNS disease remains a critical clinical challenge.
• Further research is needed to address the limitations of current HAART strategies for neurological complications.
• Optimizing prevention and treatment of HIV-induced brain dysfunction requires ongoing investigation and clinical debate.
