  • Title: Early Gamma-Band Activity During Interference Predicts Working Memory Distractibility in ADHD.
    Author: Prehn-Kristensen A, Wiesner CD, Baving L.
    Journal: J Atten Disord; 2015 Nov; 19(11):971-6. PubMed ID: 23012697.
    Abstract:
    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 50 ms 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 40 Hz-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.
