Objective To analyze the dual improvement effects of transcranial direct current stimulation (tDCS)-assisted auditory rehabilitation training on cognitive function and auditory ability of elderly patients with hearing impairment. Methods 100 cases of elderly patients with hearing impairment admitted to our hospital between January 2020 and January 2025 were prospectively selected as study subjects. The patients were divided into sham tDCS group ( N = 50) and tDCS group ( N = 50) according to the randomized numeric table method. All patients received conventional auditory rehabilitation training, and were intervened for 1 month, 3 times/week, 1 h each time. tDCS was given to patients in both groups before conventional auditory rehabilitation training, patients in the tDCS group underwent dual-site sequential high-definition tDCS stimulation, and patients in the sham tDCS group used sham dual-site sequential high definition tDCS stimulation. The main clinical assessments included hearing thresholds, Hearing Handicap Inventory for the Elderly-Screening (HHIE-S), Montreal Cognitive Assessment Scale (MoCA) and Mini-Mental State Examination (MMSE), Communication Performance Assessment (CPA), Personal Report of Communication Apprehension (PRCA-24), and 36-item Short-Form Health Survey (SF-36) scores of the patients in the two groups before and after the treatment. The correlation between hearing threshold, HHIE-S and MoCA and MMSE scores were analyzed by Pearson correlation coeffici...
