Attention deficit and hyperactivity are the most common behavioral disorders in children who are misdiagnosed. Up to a certain point, there were no reliable markers for the diagnosis of ADHD. Researchers at tel Aviv University suggested that involuntary eye movements accurately reflect the presence of such disorders.
A group of scientists used a tracking system to monitor the involuntary eye movements of two groups of adults, total of 22 people. Exercise for 22 minutes was performed as a control group that does not have ADHD, and participants with such a diagnosis. Dr. Moshe Fried says: "we had two objectives in this study: new tool for diagnostics and to check how the meds".
The researchers found a direct link between ADHD and the inability to suppress eye movement in anticipation of visual stimuli. The research also reflected improved performance of the participants taking methylphenidate, which normalized the suppression of involuntary eye movements to the average level in the control group. Frid said: "This test revealed the practical and intuitive tool for medical professionals. With all the other tests, you could be wrong, but our test was not fooled. Eye movements in this test are involuntary, so they constitute a good physiological marker of ADHD".
