Abstract | Background: Methods: A randomized, single-blind, sham-controlled crossover trial was conducted in 2021 at Mobasher Kashani Clinic, Hamadan, Iran. Sixteen patients received both five days of real- tDCS (1 mA for 20 minutes) and five days of sham- tDCS with a seven-day washout period in between. Using the Persian aphasia naming test, picture-naming accuracy and reaction time on 50 images were assessed at baseline, real- tDCS, and sham- tDCS stages. The data were analyzed using STATA software, version 11.0. P<0.05 was considered statistically significant. Results: Sixteen non-fluent PWA participated in the study. Of all patients, 64% benefited from tDCS over the STG and 18% over the IFG. The results showed that real- tDCS had a significant effect on the picture-naming accuracy (P=0.003) and the Persian-Western aphasia battery-one score (P=0.01), whereas sham- tDCS had no noticeable effects. Both the real- and sham- tDCS had no significant effect on the reaction time (P=0.28). Conclusion: Five sessions of individualized tDCS protocol (1 mA for 20 minutes) were adequate to improve picture-naming accuracy in patients with chronic aphasia.
