Differences in Resting-state Quantitative Electroencephalography Patterns in Attention Deficit/Hyperactivity Disorder...

Area of Science:

• Neuroscience
• Child Psychiatry
• Quantitative Electroencephalography (QEEG)

Background:

• Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children.
• Comorbid psychiatric conditions frequently accompany ADHD, potentially influencing its neurophysiological underpinnings.
• Quantitative electroencephalography (QEEG) offers insights into brain electrical activity patterns.

Purpose of the Study:

• To investigate the impact of comorbid psychiatric symptoms on QEEG activity in boys diagnosed with ADHD.
• To differentiate QEEG profiles in ADHD based on the presence of depressive symptoms or problematic internet use.

Main Methods:

• QEEG recordings (eyes closed, resting-state) were analyzed for absolute power in delta, theta, alpha, beta, and gamma bands.
• Participants included boys with pure ADHD, ADHD with depressive symptoms, and ADHD with problematic internet use.
• Standardized scales assessed depressive symptoms and internet addiction levels.

Main Results:

• The ADHD group with problematic internet use exhibited significantly decreased absolute theta power in central and posterior brain regions compared to the pure ADHD group.
• No significant QEEG differences were observed in the ADHD group with comorbid depressive symptoms relative to other groups.

Conclusions:

• Problematic internet use is associated with distinct electrophysiological alterations in children with ADHD, specifically reduced theta activity.
• Comorbid depressive symptoms may not manifest as significant QEEG changes in this ADHD cohort.
• Findings enhance understanding of ADHD neurobiology concerning comorbid conditions.
