Background Self-reported neurocognitive impairment (SRNI) in people living with human immunodeficiency virus type 1 (HIV-1) infection is frequent. We use longitudinal information on SRNI in the Swiss HIV Cohort Study (SHCS) to identify and characterize groups of patients with persisting SRNI over time. Methods We included all SHCS patients who were assessed for SRNI during at least 5 visits spanning at least 2.5 years in 2013–2017. We first compared patients with SRNI to those without SRNI over the whole study period. Second, we used a hierarchical cluster algorithm to identify groups of patients with similar changes of SRNI over time. In both analyses, we studied clinical and demographic factors potentially influencing SRNI. Results In total, 79 683 questionnaires of 11 029 patients contained information about SRNI, and 8545 of 11 029 (77.5%) patients had longitudinal information. The overall percentage of patients with SRNI decreased from 19.6% in 2013 to 10.7% in 2017. Compared to patients in the cluster with low-level SRNI over time, patients in the cluster with high-level persisting SRNI more often had a prior opportunistic infection of the central nervous system (CNS) (odds ratio [OR], 3.7; P <.001), imperfect adherence to antiretroviral therapy (ART) (OR, 2.8; P <.001), and depression (OR, 1.9; P <.001). Conclusions Although overall SRNI is decreasing in the SHCS, there is a group of patients with persisting SRNI over time. Past opportunistic infections of the CNS, imperfect adherence to ART, and depression were associated most with persisting SRNI. Patients with these characteristics should be preferentially tested for neurocognitive impairment. Although overall self-reported neurocognitive impairment (SRNI) is decreasing in the Swiss HIV Cohort Study, there is a group of patients with persisting SRNI over time, characterized by more past opportunistic infections of the central nervous system, imperfect adherence to antiretroviral therapy, and depression.
