Efficacy of High-precision Transcranial Direct Current Stimulation on Anxiety Disorders

HD-tDCS stimulated AD left OFC (2 mA, 20 minutes, cathode electrode placed in the Fp 1 area, and the remaining four positive electrodes placed AF3, AF7, Afz, Fpz, forming a circular 41 focused electric field mode for stimulation, twice a day, 20 minutes interval for 5 days)

The treatment parameters of the electrode were the same as the test group, the stimulation current rose to the same 2 mA current in the test group within 30 seconds, and the pre-stimulation for 1 minute, then gradually to 0 mA.
