Human immunodeficiency virus and the central nervous system

Area of Science:

• Infectious Diseases
• Neuroscience
• Immunology

Background:

• The global human immunodeficiency virus (HIV) pandemic continues to expand, with notable increases in infections among women, intravenous drug users, and ethnic minorities.
• A rapidly growing demographic within the HIV-infected population are individuals over the age of 50.
• The central nervous system and immune system are primary targets of HIV infection.

Purpose of the Study:

• To review the current understanding of HIV infection, focusing on its expanding demographics.
• To highlight the significant neurological manifestations directly caused by HIV.
• To acknowledge recent advancements in the knowledge and treatment of Acquired Immunodeficiency Syndrome (AIDS).

Main Methods:

• Literature review of recent advancements in HIV/AIDS knowledge and treatment.
• Analysis of epidemiological trends in HIV infection demographics.
• Categorization of direct HIV-related neurological complications.

Main Results:

• HIV infection is increasingly prevalent in women, intravenous drug users, ethnic minorities, and individuals over 50.
• Neurological complications are a major aspect of HIV disease.
• Identified neurological manifestations include acute and chronic meningitis, HIV-associated dementia (HAD), vacuolar myelopathy, and peripheral nervous system involvement.

Conclusions:

• HIV/AIDS remains a growing global health challenge with shifting demographic trends.
• Neurological complications are a critical and direct consequence of HIV infection.
• Ongoing research and treatment advancements are crucial for managing HIV/AIDS and its neurological sequelae.
