In 2008, researchers taught children ages 11-14 the transcendental meditation technique. After taking up meditation, there were significant reductions in stress and anxiety, as well as improvements in executive function and general ADHD symptoms. Three years later, another study by some of the same researchers looked at the effects of transcendental meditation on task performance and brain function in a similar group of school-age children. All participants showed significant improvement in five ADHD symptoms as reported by parents. The authors concluded this second study by recommending transcendental meditation as a potential non-drug treatment for ADHD.
Transcendental meditation can also be used in combination with other meditative techniques. A 2009 study looked at transcendental meditation and mindfulness meditation in children aged 6-18. Most participants had a pre-existing condition, including some with ADHD and learning disabilities. At the conclusion of the study, the authors deemed it an "effective intervention in the treatment of physiologic, psychosocial, and behavioral conditions among youth."
