Summary
Human immunodeficiency virus (HIV) affects the central nervous system (CNS) early in infection, causing cognitive and motor issues. While CNS manifestations are treatable, research continues on HIV
Area of Science:
- Neurology
- Infectious Diseases
- Neuroimmunology
Background:
- Human immunodeficiency virus (HIV) invades the central nervous system (CNS) early post-infection.
- CNS manifestations of HIV range from mild cognitive impairments to dementia in children and adults.
- Standard neuropsychological tests can diagnose and measure HIV-related CNS conditions.
Purpose of the Study:
- To review the impact of HIV on the CNS.
- To discuss the diagnosis and treatment of HIV-associated neurocognitive disorders (HAND).
- To highlight future research directions in HIV neuropathogenesis and treatment.
Main Methods:
- Review of current literature on HIV and the CNS.
- Discussion of diagnostic tools for CNS manifestations.
- Analysis of advancements in antiretroviral therapy (ART) and its impact.
Main Results:
- HIV infection frequently leads to CNS involvement with diverse clinical presentations.
- Effective treatments exist for CNS manifestations, depression, psychosis, and delirium.
- Advances in ART have transformed HIV into a chronic condition, altering patient concerns.
Conclusions:
- Early CNS invasion by HIV necessitates ongoing monitoring and management.
- Despite treatment advances, challenges remain, including psychosocial impacts and targeted CNS therapies.
- Further research into neuropathogenesis and CNS-specific treatments is crucial for improving patient outcomes.
