Electroencephalogram and Attention Deficit Hyperactivity Disorder Study

EEG and ADHD Study

The purpose of this research is to assess and determine brain oscillations or "brain signatures" of adult participants with Attention Deficit Hyperactivity Disorder (ADHD) relative to adult participants without ADHD using the technique electroencephalogram (EEG). Electroencephalogram is entirely non-invasive way of tracking brain activity.The main goal of this study is to establish biological factors for determining the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD).
