HIV-associated dementia in the era of highly active antiretroviral therapy (HAART)

Neurological complications associated with HIV-1 are being recognized as a common disorder in AIDS patients, especially patients with HIV-associated dementia (HAD). However, our knowledge of the complicated pathogenesis and clinical symptoms of HAD is limited by an incomplete understanding of the biology of HIV-1 in the nervous system. Therefore, this review focuses on the pathogenesis of HAD in the context of novel highly active antiretroviral therapy (HARRT) regimens.
