Inhibitory motor control problems: a unique criterion for diagnosing ADHD in adults
Neurosafari According to Pennsylvania State University researchers, young adults with ADHD may exhibit subtle physiological symptoms that help diagnose the disorder more accurately.
According to Neurosafari, quoted by Penn State News, in a recent study, young adults who were diagnosed with ADHD, when performing a continuous motor task, compared to other participants who did not have ADHD, had more difficulties with inhibition (translator: control). ) faced a movement reaction. In addition, participants with ADHD produced more force in performing activities.
According to the available research, attention deficit hyperactivity disorder or ADHD is a common childhood disorder whose effects and symptoms can continue in adulthood in 65% of cases.
Christina A. Nili, an assistant professor of kinesiology, says: “There are many people labeled as having ADHD, but they show different symptoms. One of the goals of our research in the field of ADHD is to find unique physiological signs and signals that will probably lead to the diagnosis of different subgroups of this disorder.”
Previous studies have shown that ADHD sufferers may have poor control over their motor system. But before recent studies, its measurement method did not have high sensitivity.
Experiment design
Dr. Neely says: “In past studies, people’s cognitive and motor functions were evaluated by examining a key press reaction, whether the person pressed a key or not.” This is while we measure exactly the amount of force (pressure) produced by the person during continuous movement activity. These types of activities (continuous movement) provide us with more information, compared to two-part yes/no activities.
In a recent study, during a continuous movement activity, participants produced force with their thumb and index finger in response to cues they saw on the screen. The participants were asked to generate force or pressure with their fingers while viewing all colors except blue color, at the same time, refrain from generating force while viewing blue color.
Dr. Neely and his colleagues found that when people had to refrain from applying force, participants with ADHD symptoms produced more force (to control or inhibit movement) compared to others. In addition, the amount of pressure produced during the test is related to specific symptoms associated with ADHD.
