Probing the Efficacy of V5/MT Stimulation on Reading and Reading-related Measures in Children and Adolescents With Developmental Dyslexia
The present study grounds on the absence of evidence-based treatment in individuals with developmental dyslexia (DD). At this topic, the present study will explore the potential effect of transcranial direct current stimulation (tDCS) over left hemispheric direct Lateral Geniculate Nucleus (LGN)-V5/MT pathway, cerebral areas usually disrupted in individuals with DD. The investigators hypothesized that active tDCS over V5/MT will boost reading skills in children and adolescents with DD. On the contrary, sham (placebo condition) tDCS over V5/MT or active (control condition) tDCS over V1 will not have significant effect in improving reading skills. Further, both active and sham tDCS will be safe and well tolerated.
