Healthy Head - Newsweek Health - MSNBC.com : "Amen's latest book, 'Making a Good Brain Great,' published this month by Harmony (a division of Random House), is based partly on research that uses brain-imaging technology, called SPECT (single photon emission computed tomography) scans, to help pinpoint problems in the brain. Patients at his clinics are injected with an extremely low dose of radioactive material. Then a technician uses a special nuclear medicine camera, which records the distribution of the radioactive material in the brain, to take a picture that reveals brain activity and blood flow. Some of the images have been reprinted in the book to show where and how Alzheimer's, drugs and disorders can affect the brain. When compared to a scan of a healthy brain, the difference is noticeable.
The good news, says Amen, is that before and after scans have also shown that brains can actually change with medication, behavioral therapy or a better diet and exercise. NEWSWEEK's Jennifer Barrett spoke with Amen about ways to improve our brain function. Excerpts:"
