Abstract

This article focuses on the relationship between cognitive dispersion—measured as intraindividual variability (IIV) across neuropsychological tests—and executive functions in persons living with HIV (PLWH). In a study of 72 PLWH, dispersion was quantified using a coefficient of variance across six tests from the Cogstate battery, and its association with executive function, psychomotor speed, and episodic memory was examined. Results showed that higher cognitive dispersion was uniquely and significantly associated with lower executive function performance, but not with psychomotor speed or memory. These findings support the theory that cognitive dispersion reflects lapses in executive aspects of attention among PLWH, highlighting the need for further research to clarify the specific executive mechanisms involved.
