| Περίληψη: | Background: Insomnia not only compromises sleep quality but may also impair learning and memory processes within cognitive function. Objective: This study aims to investigate the effects of transcranial direct current stimulation (tDCS) on offline consolidation of implicit sequence learning and sleep quality in individuals with insomnia. Methods: We employed a randomized, double-blind, controlled trial, assigning individuals with insomnia to either an active stimulation group or a sham stimulation group for consecutive 7-day interventions. Sleep quality (PSQI) and implicit sequence learning performance were assessed before and after the intervention. Results: Forty-two participants with insomnia were randomly assigned to the active stimulation group (n = 21) or sham stimulation group (n = 21). Repeated-measures ANOVA revealed significant Group × Time interactions for both sleep quality (PSQI: F(1, 40) = 31.375, p < 0.001, η Conclusions: The 7-day tDCS intervention not only effectively improved sleep quality in individuals with insomnia but also enhanced offline consolidation effects in implicit sequence learning, providing new evidence for non-pharmacological interventions for insomnia.
