Implications of Electrophysiological ADHD Endophenotypes to Predict Response to Transcranial Direct-Current Stimulation

Spanish Foundation for Neurometrics Development·observational·Posted Jul 25, 2012·Updated May 9, 2024

In Brief

An observational study evaluating Active tDCS for ADHD and ADD. Completed, enrolled 60 participants across 1 site.

Detailed Summary

In the present study the aim is to examine whether transcranial direct-current stimulation (tDCS) generated excitability changes and induce modifications of functional cortical architecture in Attention Deficit Hyperactivity Disorder (ADHD) patients. To achieve this, the investigators used an event-related potential (ERP) analysis based on 20 channel EEG recordings in ADHD subjects before and after bipolar tDCS-anode stimulation over F3/F4 or T5/T6 or P4/P3, during resting state and measure clinical scores and visual CPT tasks changes. Time courses and topography of independent component visual ERPs were compared before and after tDCS.

Interventions

Active tDCSdevice

tDCS applied to left dorsolateral prefrontal scalp area through a saline-soaked pair of surface sponge electrodes (35 cm2). The anode electrode was placed over F3 (based on the 10-20 International EEG System) of each subject. The cathode was placed over the contralateral mastoid area. A constant current of 1.1 mA was applied for 25 min/day (administered for 12 alternated days).
