A review of ADHD detection studies with machine learning methods using rsfMRI data

Abstract

Attention deficit hyperactivity disorder (ADHD) is a common mental health condition that significantly affects school-age children causing difficulties with learning and daily functioning. Early identification is crucial and reliable and objective diagnostic tools are necessary. However current clinical evaluations of behavioral symptoms can be inconsistent and subjective. Functional magnetic resonance imaging (fMRI) is a non-invasive technique that has proven effective in detecting brain abnormalities in individuals with ADHD. Recent studies have shown promising outcomes in using resting state fMRI (rsfMRI)-based brain functional networks to diagnose various brain disorders including ADHD. Several review papers have examined the detection of other diseases using fMRI data and machine learning or deep learning methods. However no review paper has specifically addressed ADHD. Therefore this study aims to contribute to the literature by reviewing the use of rsfMRI data and machine learning methods for detection of ADHD. The study provides general information about fMRI databases and detailed knowledge of the ADHD-200 database which is commonly used for ADHD detection. It also emphasizes the importance of examining all stages of the process including network and atlas selection feature extraction and feature selection before the classification stage. The study compares the performance advantages and disadvantages of previous studies in detail. This comprehensive approach may be a useful starting point for new researchers in this area. This review paper aims to give a comprehensive study that summarizes the state of the art. We believe this kind of review will accelerate researchers new to ADHD detection studies and will be a great starting point. image
