From the Paper:

"Attention Deficit/Hyperactivity Disorder (ADHD) is quite a prevalent neuropsychiatric disorder occurring in children, adolescents, and adults, being currently defined by the symptoms of lack of attention, impulsivity, and hyperactivity. Particularly, those subjects suffering from ADHD lack the inhibitory control that is necessary for self-regulation of activity and speech and thus have difficulty in suppressing their reflexive behavioral responses that are more often than not inappropriate. Diagnosis of ADHD is usually made by use of a collection of information from interviews with the subjects, rating scales of hyperactivity such as the Barkley Adult Attention Deficit Hyperactivity Disorder Rating Scale-IV (BAARS-IV) discussed in the methodology section of this research report, as well as assessment of the levels of impulsivity, performance of cognitive assessments, collection of clinical history coupled with physical and neurological examinations (Becker, Deubel & Mergner, 2002).
Many sources of information are needed because the information gathered is mainly subjective and mostly lack any significant correlation. Comorbidity of ADHD with other medical and psychiatric conditions and the fact that the classical presenting symptoms of the disorder are mainly dependent on the situation make it even more difficult to diagnose the disorder (Walsh & Hoyt, 2005). This brings in the questioning of the reliability and the consistency of the diagnostic process used currently and gives an indication that highlights are actually needed for the testing to be more objective. The current objective tests have shown potential usefulness in the identification of the sub-groups of the ADHD disorder (Becker, Deubel & Mergner, 2002).
Further research into the etiology of Attention Deficit/Hyperactivity Disorder has shown that other potentially objective diagnostic tests are available, with one possibility being the use of the alterations of the control of saccadic movements of the eye (Roger & Gompel, 2007). Saccades refer to the rapid movements of the eye that bring in new visual targets onto the fovea of the retina, the region with the highest visual acuity in the eye (Walsh & Hoyt, 2005). These rapid movements can be can be generated automatically or volitionally in response to the sensory stimuli that appearing abruptly. Studies in psychology to measure the characteristics of the saccades have indicated that those subjects with ADHD have much difficulty in suppressing their automatic and visually triggered saccades."
