Abstract:
Objective To examine the curative effect of EEG biofeedback therapy on children with attention deficit hyperactivity disorder (ADHD),and to investigate the neural mechanism underlying the executive function in children with ADHD.Methods 42 children with ADHD participated a Go/Nogo task before and after the EEG biofeedback therapy which was consisted of 20 times of treatments.The curative effect was evaluated using the behavioral and electrophysiological indexes associated with the Go/Nogo processing in the experiment.Results Commission error significantly decreased after the therapy ( (2.95 ±2.22 ) vs (4.65 ±4.47),P＜0.05 ).Latencies of P2 ( (210.00 ± 27.54) ms vs ( 228.27 ± 34.17 ) ms) and N2 components ( ( 310.59 ± 45.82) ms vs (328.00 ± 42.27)ms) elicited by Go trials significantly exhibited shorter at the end of therapy.Additionally,the amplitude of N2 component elicited by Nogo trials exhibited significantly decreased after therapy ((0.23 ±3.79)μV vs (-1.84 ± 4.23 ) μV,P ＜ 0.05).Conclusion The EEG biofeedback therapy is effective in debasing the hyperactivity/impulsive behaviors and improving the ability of target detection,which may be beneficial to the attention ability and conflict detecting in children with ADHD.EEG biofeedback is an effective treatment to ADHD.
