S.}, abstract = {Objective: Functional near-infrared spectroscopy (fNIRS) provides direct and quantitative assessment of cortical hemodynamic response. It has been used to identify neurophysiological alterations in medication-na{\~A}?ve adults with attention-deficit/hyperactivity disorder (ADHD). Hence, this study aimed to distinguish both medication-na{\~A}?ve and medicated adults with ADHD from healthy controls (HC). Method: 75 HCs, 75 medication-na{\~A}?ve, and 45 medicated patients took part in this study. fNIRS signals during a verbal fluency task (VFT) were acquired using a 52-channel system and relative oxy-hemoglobin changes in the prefrontal cortex were quantified. Results: Prefrontal cortex hemodynamic response was lower in patients than HCs (p {\^a}?? {\^a}??.001). Medication-na{\~A}?ve and medicated patients did not differ in hemodynamic response or symptom severity (p {\ensuremath{>}}.05). fNIRS measurements were not associated with any clinical variables (p {\ensuremath{>}}.05). 75.8 patients and 76 HCs were correctly classified using hemodynamic response. Conclusion: fNIRS may be a potential diagnostic tool for adult ADHD. These findings need to be replicated in larger validation studies. {\^A}{\copyright} {\^A}{\copyright}The Author(s) 2023.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85162761543&doi=10.1177\%2f10870547231180111&partnerID=40&md5=f3f7796394d3ed9eb9dedb8dad043b8b}, keywords = {adult; attention deficit hyperactivity disorder; hemodynamics; human; near infrared spectroscopy; physiology; prefrontal cortex; procedures, Adult; Attention Deficit Disorder with Hyperactivity; Hemodynamics; Humans; Prefrontal Cortex; Spectroscopy, Near-Infrared} }
