We cannot just play with brain stimulation drugs. They would create adverse effects when we do not pay proper attention to the general state of the patient. Adverse effects would destroy the brain's ability to think and concentrate. At my own practice http://southshoretms.com/ I have met with a number of patients who had become ADHD Drug Addicts. The drugs were not working so the rather new scientific innovation we call Transcranial Magnetic Stimulation Therapy was utilized. The new technique works, but it cannot stop drug addiction.
