Improving central auditory processing features following two electrode montage of transcranial direct current stimulation (Tdcs) in children and adolescents with dyslexia

transcranial direct current stimulation (tDCS) has been used as a safe and non-invasive method for children and adolescents with dyslexia. Our aim in this study was to investigate the effect of tDCS on central auditory processing variables in behavioral and electrophysiological aspects with two electrode arrays on superior temporal gyrus (STG). Seventeen children and adolescents with dyslexia with age range 9-15 years underwent speech in noise perception test, auditory verbal memory test and LLAEP assessment in a baseline condition without tDCS ,sham ( placebo) and after 20 min of exposure with 1 mA current to two different tDCS statuses: anode electrode of tDCS on left STG / reference electrode on right shoulder and anode electrode on the left STG/ reference electrode on right STG to enhance left lateralization (offline) .Our results showed improved speech in noise perception and memory and reduced latency and increased amplitude of the waves P1, N1 and P2 with both electrodes arrangement (P
