Neurocognitive impairments following central nervous system opportunistic infections and HIV-associated dementia (HAD) were common clinical features of HIV infection prior to anti-retroviral therapy. As HIV infection has evolved from an invariably fatal disease with a poor prognosis to a condition requiring long-term management, HIV-related neurocognitive disorders have been the subject of increasing research. This review will examine the recent changes in the understanding of the HIV-associated neurocognitive disorders (HAND) including the changing epidemiology, risk factors associated with its development, methods for screening for the disorders and evolving treatment options.

Social Engagement and Neurocognition in Latino and Non-Latino White Older Persons with HIV.
AIDS Behav
December 2024
Department of Medicine (Division of Geriatrics), Department of Psychiatry and Behavioral Sciences, Duke University, Durham, NC, USA.
The present study investigated differences in the quantity and quality of social engagement, and their associations with neurocognition among older Latino and non-Latino White persons with HIV (PWH). Participants were age 50 + community-dwelling PWH living in southern California (n = 116; 50% Latino [53% Spanish-speaking], 50% non-Latino White; Age: M = 58.03; Education: M = 13.

Neurocognitive impairment (NCI) is present in around 40% of people with HIV and substantially affects everyday life, adherence to combined antiretroviral therapy (cART) and overall life expectancy. Suboptimal therapy regimen, opportunistic infections, substance abuse and highly prevalent psychiatric co-morbidities contribute to NCI in people with HIV. In this review, we highlight the need for efficacious treatment of HIV-related NCI through pharmacological approaches and cognitive neurorehabilitation, discussing recent randomized controlled trials in this domain.

- HIV significantly affects neurocognitive function in Africa, leading to high prevalence rates of neurocognitive disorders, with Central and South Africa showing the highest impairment levels (around 49.33%).
- Variability in neurocognitive impairment prevalence is influenced by factors like ART availability, healthcare infrastructure, and co-infections, emphasizing the need for targeted interventions.
- Addressing this issue requires collaboration among healthcare providers, policymakers, and communities, focusing on education, early detection, improved resources, and research partnerships to better support individuals living with HIV.
Clustering of cognitive domains among older persons with HIV.

Article Synopsis
- - The study investigated the cognitive profiles of older people with HIV (OPWH) undergoing combined antiretroviral therapy, focusing on how age interacts with HIV-related cognitive disorders.
- - Researchers conducted a cross-sectional analysis of 330 OPWH aged 50 and older, using neuropsychological tests to evaluate cognitive functions and identify clusters of cognitive impairment.
- - Results showed three distinct cognitive clusters: one with significant memory impairments, another with language and abstraction issues, and a third with no specific domain impairments, suggesting variations based on both HIV-related and other individual factors.
A Transcriptional Signature of Induced Neurons Differentiates Virologically Suppressed People Living With HIV from People Without HIV.

Neurocognitive impairment is a prevalent and important co-morbidity in virologically suppressed people living with HIV (PLWH), yet the underlying mechanisms remain elusive and treatments lacking. Here, we explored for the first time, use of participant-derived directly induced neurons (iNs) to model neuronal biology and injury in PLWH. iNs retain age- and disease-related features of the donors, providing unique opportunities to reveal novel aspects of neurological disorders.
