Transcranial Direct Current Stimulation in the Treatment of Dyslexia: a Randomized Double-blind Study.
In Brief
A clinical study evaluating Active tDCS and Sham tDCS for Dyslexia. Completed, enrolled 28 participants across 1 site.
Detailed Summary
The present study grounds on the absence of evidence-based treatment in individuals with dyslexia. At this topic, the present study will explore the potential effect of transcranial direct current stimulation (tDCS) over parieto-occipital brain regions, cerebral areas usually disrupted in individuals with dyslexia. tDCS will be administered without concomitantly training. Therefore, the investigators hypothesized that active tDCS over parieto-occipital areas will enhance reading skills in children and adolescents with dyslexia. On the contrary, sham tDCS (placebo) over parieto-occipital areas will not have significant effect on reading. Further, both active and sham tDCS will be safe and well-tolerated.
Study Details
Timeline
Interventions
Active tDCS will be delivered to parieto-occipital areas for five consecutive days. tDCS will be delivered by a battery driven, direct current stimulator through a pair of saline-soaked sponge electrodes kept firm by elastic bands. The electrodes will be placed on the left (anodal) and right (cathodal) parieto-occipital areas, PO7 and PO8 position according to the 10-20 international EEG system for electrode placement. Stimulation intensity will be set at 1 milliampere (mA), the duration of stimulation will be 20 min.
Sham tDCS will be delivered to parieto-occipital areas for five consecutive days. tDCS will be delivered by a battery driven, direct current stimulator through a pair of saline-soaked sponge electrodes kept firm by elastic bands. The electrodes will be placed on the left (anodal) and right (cathodal) parieto-occipital areas, PO7 and PO8 position according to the 10-20 international EEG system for electrode placement. Stimulation intensity will be set at 1 milliampere (mA), but the current will be applied for 30 s and will be ramped down without the participants awareness.
