Attention Deficit/Hyperactivity Disorder (ADHD)
Our clinical evaluations of ADHD include objective assessment of the three core ADHD symptoms: 1) Inattention, 2) Hyperactivity, and 3) Impulsivity. We systematically evaluate problematic behavior, employ focused neuropsychological testing, and measure the consequences of inattention on broader cognitive function (e.g., learning, memory, organization).
There are many ways of assessing ADHD. The Quotient ADHD System is an innovative, FDA-approved device that simultaneously measures attention and hyperactivity. Based on research from the McLean Hospital, a Harvard Medical School Affiliate, this assessment tool uses advanced motion tracking technology to measure micro-movements while individuals complete a 15-20 minute computerized test. After the test is completed, patterns of motion, accuracy of responses, and fluctuations in attention state are calculated, which provide valuable insights into both the existence of ADHD and the severity of the disorder.
Data collected from the advanced motion tracking system captures motor activity for the entire Quotient ADHD test, providing a sensitive measure of behavioral regulation deficits. When compared with baseline testing, repeat testing after treatment can clearly show changes in motor activity that are indicative of treatment response, as indicated below with the motion sensor.
With Quotient's attention state analysis, we can examine moment to moment changes in an individual's ability to pay attention. Low overall attention and frequent shifts between attention states are highly correlated with ADHD. If attention fails over the course of the task, we can detect the results - does the patient become impulsive, distracted, or totally disengaged? Like motion analysis, attention state analysis clearly reveals the impact of treatment response.
ADHD can sometimes be difficult to diagnose, in part because comorbidity rates are high and symptoms of ADHD overlap with other disorders. As a result, it is important to integrate quantitative data in addition to rating scales and clinical examination to guide treatment planning. To learn more about clinical applications, please review the following case studies:
Jake - treating motor dysregulation does not always address inattention
Amanda - inattention is not always caused by ADHD
Eric - sometimes ADHD medications are warranted but need to be adjusted over time
