Abstract

Fast Periodic Visual Stimulation (FPVS) offers an objective approach for investigating neural responses to emotional stimuli. This study explores the use of FPVS to identify neurophysiological markers associated with Attention Deficit Hyperactivity Disorder (ADHD) by comparing brain responses between ADHD and Non-ADHD participants. EEG data were collected while participants viewed sequences of neutral faces mixed with emotional oddball expressions (Angry, Fear, Happy, and Sad). Frequency-domain analyses were performed to compute Baseline-Corrected Amplitudes (BCA) and Signal-to-Noise Ratios (SNR) across occipitoparietal, occipitotemporal, parietal, and frontal regions of interest. Results revealed significantly reduced BCA and SNR values in ADHD participants, particularly in the Occipitotemporal and Parietal regions. Additionally, SNR analyses indicated less distinct neural responses of ADHD participants. Notably, a significant Group × Condition interaction was observed in the Frontal ROI. These findings support the potential of FPVS as a promising tool for identifying objective neural markers of emotional dysregulation in ADHD.
