Daniel Amen

Daniel Gregory Amen (born 1954) is an American celebrity doctor who practices as a psychiatrist. He is the founder and chief executive officer (CEO) of Amen Clinics. He is also the founder of Change Your Brain Foundation, BrainMD, and Amen University. He is a twelve-time New York Times best-selling author as of 2023. Amen has built a profitable business around the use of the controversial practice of SPECT (single-photon emission computed tomography) imaging for diagnostic purposes. His marketing of SPECT scans and much of what he says about the brain and health in his books, media appearances, and marketing of his clinics have been condemned by scientists and doctors as lacking scientific validity and as being unethical, especially since the way SPECT is used in his clinics exposes people to radiation with no clear benefit. Amen has studied brain injuries affecting professional athletes and has consulted on post-concussion issues for the National Football League.
