Abstract: Abs tractAim: Attention-deficit/hyperactivity disorder (AD/HD) is a common neuropsychiatric disorder resulting from disruptions in circuits that regulate attention and action.Many studies have revealed different parameters of AD/HD through neurophysiological measurements.The purpose of this study is to compare visual evoked potentials (VEPs) latency and amplitude in AD/HD patients.This study aims to discuss the effects of disease severity and psychostimulants use on the central nervous system based on VEP measurements.Methods: The study was designed using a retrospective-descriptive methodology, including a total of 30 patients diagnosed with AD/ HD, 15 of whom were taking psychostimulant medication and 15 of whom were not, who presented to the psychiatry outpatient clinic between January 2024 and June 2024.P-100 amplitude and latency were recorded for both eyes.In AD/HD patients, these values were compared based on the severity of the disease, between those who receive treatment and those who do not.Results: There was no statistically significant difference between latency and amplitude values according to disease severity.The difference was statistically significant between P-100 latency according to psychostimulant use (p=0.046,p=0.016).With regard to the use of psychostimulants, there was no significant difference in the amplitude values.Conclusion: VEP studies with increased sample size AD/HD, with additional confounding variables, will provide insight into information processing and shed light on the pathophysiology of AD/HD.
