Effectiveness of the VR Cognitive Training for Symptom Relief in Patients with ADHD

This study aimed to verify the effectiveness of virtual reality (VR) cognitive training by measuring the sense of presence and electroencephalography (EEG) in children with ADHD. A clinical trial was conducted to verify the effect of VR cognitive training on children with ADHD. The experimental group included eight children with ADHD, and the control group included eight healthy children without ADHD. The sense of presence increased significantly after the VR cognitive training in children with ADHD. Also, no significant changes in the alpha, beta, delta, and gamma wave amplitudes were found in both groups after the VR cognitive training. Thus, the VR training content developed in this study can help measure the patients' behavioral inhibition, increase their sense of presence by inducing interaction with distraction stimuli, and alleviate their symptoms. However, EEG could only be used as an auxiliary means, at the clinician's judgment, for ADHD diagnosis in children because no significant EEG changes were observed in the experimental or control groups after the VR cognitive training.
