Neurofeedback Training for Dyslexia

Not Applicable

• Conditions: Reading Problem; Dyslexia
• Interventions: Device: ProComp5 Infiniti System w/BioGraph Infiniti Software; Device: ProComp5 Infiniti System w/recorded videos

• Registration Number: NCT04989088
• Lead Sponsor: Catholic University of the Sacred Heart

Brief Summary

The study aims at testing a Neurofeedback (NF) training specifically designed for inducing a functional hemispheric imbalance of the tempo-parietal regions in individuals with dyslexia. A randomized clinical trial aimed at comparing two experimental conditions is described: a) Left theta/beta NF training in combination with right beta/theta NF training and b) sham NF training.
