RI) to examine brain structure, including changing volumes in white matter and hints of vascular damage; MR spectroscopy to assess chemical processing; functional MRI to look at the brain’s reaction to stimulus; positron emission tomography (PET) and glucose PET scanning to examine the functional aspects of performance; and the newest modality, amyloid imaging, which can provide a picture of amyloid deposition in the brain. Dr. Jack’s research has formed the basis of a $60 million, five-year grant, funded by a partnership of industry and the National Institute on Aging, to study these techniques nationwide, according to Dr. Petersen.

Through these studies, Dr. Petersen hopes doctors will be able to provide answers to those worried about developing Alzheimer’s disease -- something no one has ever been able to do.

“Having a predictive equation will allow us to say, ‘You have a certain probability of developing Alzheimer’s,’” he says. “And if the probability is high, and if the therapy is risky or expensive, this information may help us determine how to intervene.”  Source:Mayo Clinic
