Diagnosis of ADHD children by wavelet analysis

The aim of this study was to find a diagnostic method to distinguish children with attention deficit hyperactivity disorder (ADHD) from their healthy counterparts. The method presented here was based in the characterization of scalograms that result from applying a Continuous Wavelet Transform (CWT) to blood oxygen level dependent (BOLD) signals. This data was obtained from control and ADHD patients during resting state functional magnetic resonance imaging (fMRI) of the whole brain. Significant differences between the two study groups were obtained in regions known to be affected by ADHD as well as other less usual regions.
