Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Summary

This summary is machine-generated.

Researchers identified specific brain activity patterns in the insula linked to attentional bias in gaming disorder. A novel neurofeedback approach, DecABT, shows promise in reducing gaming stimulus attractiveness by targeting these neural mechanisms.

Area of Science:

Neuroscience
Psychiatry
Computational Neuroscience

Background:

Increasing smartphone and computer game use correlates with rising gaming disorder prevalence.
Gaming disorder is often characterized by attentional biases towards gaming stimuli.
Previous research on attentional deficits in gaming disorder has shown inconsistent results, possibly due to the dynamic nature of bias.

Purpose of the Study:

To investigate the neural mechanisms underlying dynamic attentional bias states in individuals with probable gaming disorder.
To explore the role of the insula in regulating attentional bias specific to gaming stimuli.
To develop and test a novel neurofeedback intervention, decoded attentional bias training (DecABT), for gaming disorder.

Main Methods:

Functional magnetic resonance imaging (fMRI) combined with a personalized approach-avoidance task.
Multivariate pattern analysis of brain activity in 21 participants with probable gaming disorder.
Proof-of-concept fMRI-decoded neurofeedback targeting insula activity patterns.

Main Results:

Insula activity patterns were found to track temporal attentional bias states specific to gaming stimuli.
A broader network of frontal and parietal regions predicted general temporal attentional bias.
Preliminary results suggest DecABT may reduce gaming stimulus attractiveness via insula and precuneus mechanisms.

Conclusions:

The insula plays a key role in the endogenous regulation of attentional bias states in gaming disorder.
Decoded attentional bias training (DecABT) offers a potential individualized therapeutic approach for addiction.
This study provides a foundation for developing novel neurofeedback-based treatments for gaming disorder.
