On the day of the ultrasound appointment, patients will undergo ten minutes of ultrasound targeting the anterior cingulate. The DWL Doppler ultrasound device enables visual and auditory waveform confirmation of the anterior cerebral artery, and optical tracking technology (e.g., AntNeuro Visor2™ system) may be used in tandem with the Brainsonix ultrasound device to track a patient's brain in virtual space as well as their physical location, thereby ensuring accurate placement.

Each participant will undergo 8 consecutive weekly sessions (each session is 10 minutes long) of focused ultrasound with the Brainsonix Pulsar 1002 device.

This instrument is designed to evaluate for severity of symptoms as specified in the DSM-IV-TR. The ASRS is composed of 18 questions, and uses a scale that ranges from 0-4 based on the individuals mark in either the "never, rarely, sometimes, often, very often" column for a possible total score of 72. The minimum score to qualify for study inclusion is 8 (i.e., 4 or more "symptom-positive" answers), and the maximum possible score is 72. The higher the score, the more indicative of higher severity of ADHD symptoms. Each column is used to describe the severity of the individuals symptoms based on the questions asked. Each participant is asked to make a mark within one column for each question that best describes their answer. The first 6 questions of the scale comprise Part A, which is more generally used as a screening measure. Questions 12-18 comprise Part B, which provides further identifying clues for individual symptoms.

Improvement will be gauged by reduction in overall score (minimally clinically important difference will be 20% for this study).
