Attention deficit hyperactivity disorder (ADHD) is becoming increasingly common in American children and is carrying over into adulthood. The neurodevelopmental disorder contributes to difficulty concentrating and functioning in social settings as well as in school and/or at work. Pharmacotherapy is currently viewed as the primary way to treat ADHD. However, medication does not work for everyone with ADHD, and for some, the adverse side effects from the medication causes them to discontinue their medication. The emerging field of study into transcutaneous vagus nerve stimulation (tVNS) as a method to treat neurological disorders shows promise in its application to ADHD. This study seeks to determine if auricular tVNS is a safe and effective method to treat ADHD as a replacement to current medications, and to set guidelines for the stimulation parameters needed for ADHD. Additionally, electroencephalography (EEG) will be investigated in this study as potential method to objectively measure symptom improvement for ADHD.
