Human immunodeficiency virus (HIV) continues to be a serious public health problem in our country
in the world and has serious effects on the central and peripheral nervous system. HIV‑associated
dementia (HAD), which may develop due to HIV infection, causes subcortical dementia that can
progress with marked slowdown in reaction time and psychomotor speed, impaired cognitive
flexibility, emotional lability, and apathy. Neurocognitive tests are the most appropriate tools for the
neurocognitive assessment and staging of the disease. In this context, the Addenbrooke’s Cognitive
Examinations Revised (ACE‑R) test may be preferred in the neurocognitive evaluation of patients
considered to have HAD, in terms of its repeatability and easy applicability, as it allows us to
evaluate many neurocognitive functions in detail.
