Among the general public, Dr. Daniel Amen's work is popular. His books have been on The New York Times' best-seller lists, according to WebMD. In 2012, his clinics saw 1,200 patients per month, The Washington Post states, but some members of the medical profession disagree with his treatment methods.
Along with the clinics, Dr. Amen's business sells DVDs, arranges TV and lecture engagements, and offers nutritional supplements, The Washington Post reports. In addition, the American Psychiatric Association identified Dr. Amen as a distinguished fellow, which is the organization's highest level of distinction, WebMD states. He has hosted several well-received PBS shows concerning the brain and also had many articles published in peer-reviewed journals, such as the Journal of the American Academy of Child and Adolescent Psychiatry and the Journal of Neuropsychiatry and Clinical Neuroscience.
Dr. Amen's use of nuclear imaging tests to aid in diagnosing and exploring mental conditions has been criticized by members of psychiatric and neuroscience groups, explains The Washington Post. Dr. Amen uses biomarkers in images to identify mental illnesses. Critics believe his assertions have not been scientifically validated. According to opponents, not enough research exists to support his use of brain imaging technology. They claim biomarkers are not yet useful for diagnosis.
