The global burden of cognitive impairment in people with HIV

Lack of data from more than 70% of the world's countries, cohorts being unselected for symptoms in most research studies, and limitations of the HIV-associated neurocognitive disorder/Frascati criteria restrict the ability to accurately determine the global burden of cognitive impairment in PWH. More studies in low-resource settings and a standardized approach to assessing cognitive impairment, bridging research and clinical realms, are needed.
