In this randomized clinical trial, LDH produced acute and short-term improvements in verbal learning, memory, and attention in virally suppressed women with HIV. These findings suggest that HPA axis modulation may represent a therapeutic pathway for cognitive dysfunction in HIV. Peripheral biomarkers did not account for these cognitive benefits, suggesting that other biological mechanisms may underlie LDH’s effects.
