Attention deficit in children with developmental coordination disorder: evidence from resting state EEG.
L’essentiel
Individuals with developmental coordination disorder (DCD) often exhibit attentional deficits, which may be detectable in resting-state electroencephalography (EEG). The present study aimed to examine resting-state EEG oscillatory activity in children with DCD. Five-minute resting-state EEG recordings were obtained from 23 children with DCD and 24 typically developing controls. Independent-samples t-tests were used to compare theta power, alpha power, and theta/beta ratios across brain regions between groups. Results indicated that children with DCD demonstrated significantly elevated theta power and higher theta/beta ratios compared with controls. No significant between-group differences were observed in alpha power. Although no definitive neural biomarker for DCD was identified, the present findings suggest that distinct patterns in theta oscillations may reflect atypical central nervous system activation underlying motor function during rest in children with DCD. These results highlight the need for larger-scale investigations of EEG spectral profiles to further elucidate the neurophysiological mechanisms of DCD.
