The Quotient™ ADHD System Test only takes minutes to complete, is remarkably simple in design, and immediately yields objective information on the actual levels of the three core symptoms of ADHD. The patient’s responses to the demanding yet monotonous series of tasks presented during the Quotient™ ADHD System Test enable the precise assessment of the patient’s ability to maintain focus, inhibit impulses and control physical activity in a controlled and reproducible setting.
Although such a challenge test may appear simple, the Quotient™ ADHD System Test requires the patient to maintain attention and control hyperactivity and impulsivity, much in the same way as one must do in a classroom or workplace.
Measuring Hyperactivity
Among other important measurements, the tracking and analysis of a patient’s movements is an important feature of the Quotient™ ADHD System that sets it apart from other diagnostic tools for ADHD. Research indicates that measurements of motion or hyperactivity may be one of the most critical indicators of the presence of ADHD.
Small spherical reflectors are placed on the forehead (and legs if the patient is over 12 years old) of the patient, who is seated comfortably at the test kiosk. During the Quotient™ ADHD System Test, an infrared Motion Tracking System (MTS) records each movement and the pattern of movement of the reflectors. The MTS is precise, capturing movements and patterns as small as 0.4 mm, 50 times each second throughout the 15-20 minute Quotient™ ADHD System Test.
Measuring Inattention & Impulsivity
During the Quotient™ ADHD System Test period, different geometric shapes flash at random positions on the screen. The patient is asked to identify and respond, as quickly and as accurately as possible, to certain shapes while ignoring other shapes. In order to evaluate the shifts in attention, the Quotient™ ADHD System divides the 15 to 20-minute test into 30-second segments and captures whether the patient was On -Task, Impulsive, Distracted, Random, Minimal, or Contrary during each of these 30-second periods. Research indicates that the number of shifts between attention states is important in the assessment of ADHD.
