Brief Summary

Dyslexia is the most common neurobehavioral disorder affecting children, with prevalence rates ranging from 17.5% to 21%. Studies have shown incomplete response to remediation and behavioural therapies in children with dyslexia. Evidence from neuroimaging studies as well as neuromodulation studies supporting a neurobiological basis of dyslexia is extensive according to which under-activation and poor connectivity in the underlying pathways for language and reading is the primary pathophysiology underlying reading difficulties. Evidence from studies on neuromodulation have shown that by combining remedial intervention with neuromodulation there is a synergistic effect through the mechanism of long term potentiation. In view of the above mentioned our study aims to investigate the role of Hf rTMS as an adjunct to AI enabled remedial intervention in children with dyslexia in improving their reading abilities.
