Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children, characterized by symptoms such as hyperactivity, inattention and impulsivity, which often impairs the quality of life and successful performance. The disorder is associated with neurological, genetic and environmental factors affecting brain structure and cognitive function. Treatments include first-line pharmacological treatment, psychological therapy and neurofeedback training. Neurofeedback training with electroencephalography aims to regulate brain activity by targeting the dysregulated theta and beta rhythms, and the theta/beta ratio through personalized or standardized neurofeedback protocols to reduce ADHD symptoms and to improve cognitive function. This study aims to compare differences in the change of theta, beta and the individual alpha peak frequency (iAPF) based on personalized and standardized neurofeedback protocols targeting theta, beta and the theta/beta ratio. Nine children (age 7 to 13) were randomly assigned 16 sessions of personalized or standardized neurofeedback training over a span of two weeks; the neurofeedback protocol was personalized with the help of the iAPF. The theta and beta rhythms and the iAPF were measured by a quantitative electroencephalography and compared before and after the intervention by non-parametric Mann-Whitney-U, Wilcoxon Signed-Rank and Kruskal Wallis tests. These tests showed no significant difference between theta, beta and iAPF before and after the neurofeedback training within and across the personalized and standardized test groups. Previous studies showed an improvement of brain activity and cognitive function through neurofeedback training, but the small sample size and participant artifacts limited this study; concluding that valuable insights into neurofeedback training were gained.
