AIDS Dementia Market to Reach USD 2.7 Billion by 2034

AIDS dementia, also known as HIV-associated neurocognitive disorder (HAND) or HIV-associated dementia (HAD), is a neurological complication that occurs in advanced stages of HIV infection. Despite the global success of antiretroviral therapy (ART) in reducing HIV-related morbidity and mortality, cognitive decline remains a persistent challenge for many patients, particularly in low-resource settings.

The condition is caused by HIV's direct effects on the central nervous system (CNS) and compounded by opportunistic infections, chronic inflammation, and long-term ART toxicity. While ART has reduced the prevalence of severe dementia, milder forms of HAND continue to affect up to 50% of HIV-positive individuals worldwide.

Growing investment in neuroprotective agents, CNS-penetrating ART regimens, and biomarker-based diagnostics is driving market expansion. Increasing awareness and global initiatives to integrate neurological care into HIV management further strengthen the market outlook.
