In a recent study published in the Journal of Developmental & Behavioral Pediatrics, Stewart H. Mostofsky, M.D., director of the Center for Neurodevelopmental and Imaging Research at Kennedy Krieger Institute, and Karen E. Seymour, Ph.D., assistant professor of Psychiatry and Behavioral Sciences at Johns Hopkins University School of Medicine, found that a mindful movement (Tai-Chi)-based training intervention was associated with significant improvements in school-age children with ADHD and improved their ability to regulate hyperactive, impulsive and inattentive behavior.
