Treating developmental dyslexia using transcranial stimulation combined with a reading stimulation program: A pilot study

Objective: Evaluate the effect of transcranial direct current stimulation (tDCS) combined with reading therapy on performance tasks in a serie cases children and adolescents developmental dyslexia (DD). Method: (IRB/UNIFESP number:1281/2017). Four dyslexic students (two two adolescents) were evaluated regards to rate accuracy fluency three occasions: pre-intervention as well one six months after intervention. The intervention consisted five consecutive sessions active tDCS (1 mA for 20 minutes), followed by two-day interval another cognitive skills phonological processing decoding words. Anodal was administered over left parieto-occipital cortex, cathode placed contralateral deltoid muscle. Each session preceded execution semantic-lexical evocation tasks. Data analyzed using Friedman test JT method analysis clinical significance reliable change index. Results: Improvements found text word at one-month six-month evaluation. A significant increase correct words pseudowords Most improvements reliable, some cases. Conclusion: Transcranial program proved effective improving these participants.
