Early Gamma-Band Activity During Interference Predicts Working Memory Distractibility in ADHD

Objectives: Patients with attention-deficit/hyperactivity disorder (ADHD) display deficits in working memory (WM) and enhanced distractibility. Methods: Evoked gamma-band response (GBR) occurs already 50ms after stimulus onset and is modulated by attention. 16 boys with ADHD and 20 healthy controls...

Zusammenfassung:	Objectives: Patients with attention-deficit/hyperactivity disorder (ADHD) display deficits in working memory (WM) and enhanced distractibility. Methods: Evoked gamma-band response (GBR) occurs already 50ms after stimulus onset and is modulated by attention. 16 boys with ADHD and 20 healthy controls (10-14 years) completed a WM task with distraction. Results: Occipitally evoked 40Hz-GBR was higher during distraction in ADHD than controls. GBR correlated negatively with interference control. Conclusion: These data suggest that ADHD patients are disturbed by interference on an early level of perception.
