In HIV-associated neurocognitive disorder, memory deficits are primarily due to which process?

Memory problems in HIV-associated neurocognitive disorder primarily arise from inefficiencies in encoding information and in retrieving it later. The condition often disrupts frontal-subcortical circuits that support attention, processing speed, and retrieval strategies. When encoding is inefficient, new information isn’t stored robustly, making learning harder. When retrieval is impaired, information that was encoded can still be difficult to access, producing forgetfulness even when the memory trace exists. This pattern fits HAND and is seen in neuropsychological testing as reduced learning across trials and disproportionate retrieval difficulties, with recognition sometimes relatively spared. Mood symptoms, language issues, or visuospatial problems can occur, but they don’t explain the memory deficits as specifically as encoding and retrieval problems do.
