Brain Function Characteristics of Children with Attention-Deficit/Hyperactivity Disorder Aged 4-9 Years During a GO/NOGO Task: An Functional Near-Infrared Spectroscopy Study

The findings suggest that prefrontal region abnormalities are present in children with ADHD at early developmental stages. This underscores the importance of targeting the prefrontal cortex in interventions and highlights the role of multi-network coordination in ADHD-related brain abnormalities. Limitations include the cross-sectional design and relatively small sample size, which should be addressed in future longitudinal studies.
