Neurobiological Aspects of the Attention Deficit Hyperactivity Disorder

Neurobiological Aspects of the Attention Deficit Hyperactivity Disorder: Contribution of the Transcranial Direct Current Stimulation in Control Inhibitory.

Evaluating neurobiological disorder associated with Attention Deficit Hyperactivity Disorder (ADHD) and the contribution of transcranial direct current stimulation (tDCS) in the adaptation of inhibitory control.

1. Assess the neurobiological aspects evidenced by the amount of brain electrical activity observed by the amplitude of waves through graphs in patients with ADHD, using quantitative electroencephalography;
2. Study the contribution of transcranial direct current stimulation compared with sham in the adequacy of inhibitory control in ADHD patients through neuropsychological test-Go/No Go;
3. Assessing the efficacy of tDCS in neurobiological parameters evidenced by quantitative EEG in patients with ADHD;
4. Perform the Reconstruction of the Functional Brain Network of each subject based on the quantitative EEG data through computational and mathematical modeling;
5. Register indicators of quality of life in adults with Attention Deficit Hyperactivity Disorder through the Quality of Life Questionnaire for Adults with ADHD (AAQoL).
