Our ADHD doctors in San Antonio use neurofeedback to identify the root of the problem. ADHD (attention deficit disorder) may be caused by many factors, including brainwave imbalance. ADHD symptoms include trouble focusing, impulsive actions and distraction. Recent studies support brainwave imbalance as a contributor to ADHD symptoms, showing that people with ADHD have too many theta waves and not enough beta waves. Neurofeedback can bring balance to brainwaves, diminishing the symptoms of ADHD.
