Insights
Neurofeedback training (NFT) significantly improves executive functions, particularly inhibitory control and working memory, in children with attention deficit hyperactivity disorder (ADHD). Longer NFT durations yield greater benefits and sustained effects.
Area of Science:
- Neuroscience
- Clinical Psychology
- Pediatrics
Background:
- Children with attention deficit hyperactivity disorder (ADHD) frequently exhibit executive function deficits.
- These deficits can significantly impact academic, social, and emotional development.
- Effective interventions are crucial for managing ADHD-related executive dysfunction.
Purpose of the Study:
- To evaluate the efficacy of neurofeedback training (NFT) in enhancing executive functions in children diagnosed with ADHD.
- To determine if specific NFT parameters, such as duration, influence treatment outcomes.
- To assess the long-term effects of NFT on executive functions in this population.
Main Methods:
- A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted.
- Studies were selected based on stringent inclusion/exclusion criteria and assessed for quality using the PEDro scale.
- Seventeen RCTs involving 939 participants were analyzed.
Main Results:
- Neurofeedback training (NFT) demonstrated significant improvements in global executive function, inhibitory control, and working memory in children with ADHD.
- NFT sessions exceeding 1,260 minutes were more effective in enhancing inhibitory control and working memory.
- The positive effects of NFT on inhibitory control and working memory were found to be enduring.
Conclusions:
- Neurofeedback training (NFT) is an effective intervention for improving inhibitory control and working memory in children with ADHD.
- Optimal NFT duration, particularly exceeding 1,260 minutes, maximizes benefits for working memory and inhibitory control.
- NFT offers sustained improvements in key executive functions, supporting its clinical utility for ADHD management.
Abstract:
Executive function deficits are commonly observed in children diagnosed with attention deficit hyperactivity disorder (ADHD). This research investigates the effectiveness of neurofeedback training (NFT) in improving executive functions among this group. Studies were meticulously selected following stringent inclusion and exclusion criteria. The quality of these studies was assessed using the PEDro scale. Seventeen RCT studies were identified, totaling 939 participants. We observed significant improvements in global executive function (p < 0.055), inhibitory control (p < 0.0001) and working memory (p < 0.05) following NFT. Notably, NFT exceeding 1,260 min was more effective in enhancing inhibitory control (p < 0.01) and working memory (p < 0.01). Additionally, the effects of NFT on inhibitory control (p = 0.05) and working memory (p < 0.01) were found to be enduring. NFT is an effective intervention for improving inhibitory control and working memory in children with ADHD. Working memory exhibits a more significant enhancement when the duration exceeds 1260 min, while inhibitory control follows closely behind. Moreover, it has a more sustained effect on working memory, alongside a notable albeit secondary effect on inhibitory control.
