Frontal EEG alpha-delta ratio and social anxiety across early adolescence

Although the mean age of onset of social anxiety disorder (SAD) is during adolescence, we know relatively little about the neurodevelopmental correlates of subsyndromal social anxiety in early adolescence before SAD manifests. Here we examined frontal EEG alpha/delta ratio (a putative proxy of brain maturation) in relation social anxiety symptoms across early adolescence. Resting regional EEG spectral power measures were collected continuously …
