HIV-Associated Dementia

HIV-Associated Dementia is a brain disorder that occurs in people infected with the human immunodeficiency virus (HIV). It affects the central nervous system, leading to problems with thinking, memory, and movement. People with this condition may experience difficulty concentrating, slowed thinking, and changes in behavior or mood. The disease results from the virus damaging brain cells and causing inflammation. This condition can significantly impact daily activities and quality of life. Early recognition of symptoms is important for managing the disease.

HIV-Associated Dementia (HAD) is a progressive neurocognitive disorder caused by direct infection of the brain by HIV, leading to neuronal injury and subcortical dementia. The pathogenesis involves viral replication in microglia and macrophages, triggering chronic neuroinflammation and release of neurotoxic substances. Clinically, HAD presents with cognitive decline, motor dysfunction, and behavioral changes. It is a major complication of advanced HIV infection and reflects severe immunosuppression. Diagnosis is important as it indicates central nervous system involvement and worsened prognosis in HIV patients.
