HIV And Dementia

HIV-associated dementia, a consequence of advanced HIV infection, shares commonalities with Alzheimer's disease and other forms of dementia. Both conditions manifest through cognitive decline, memory loss, and behavioral changes. However, HIV-associated dementia typically emerges in the later stages of untreated HIV/AIDS when the virus affects the brain. In contrast, Alzheimer's disease involves progressive neurodegeneration unrelated to HIV infection. Effective antiretroviral therapy (ART) has significantly reduced the occurrence of HIV-associated dementia. Unlike Alzheimer's, which predominantly affects older adults, HIV-associated dementia can impact younger populations when HIV is untreated, emphasizing the critical role of early diagnosis and treatment in managing cognitive complications linked to HIV/AIDS.
