Profile

1. Development of diagnostic methods for early, prodromal, and preclinical dementia
We construct a large set of brain image database with longitudinal observations, and develop tools to detect fine morphological / functional deviations from estimated normal aging to detect very early change in dementia. We collaborate with Brain Bank group to conduce PET-pathology comparison which enable us to establish clinical significance of PET examinations. We tackle not only Alzheimer's disease, but also non-Alzheimer type dementias such as dementia with Lewy bodies and tauopathies

2. Research on amyloid imaging for clinical implementation
In the mid-term plan of 2013-2017, we strongly promote research on amyloid imaging for the clinical implementations. We participate in multi-center dementia studies of national and international scales such as World Wide ADNI studies and DIAN-Japan study in which we are in charge of Amyloid PET Core. We promote clinical trials of diagnostic and therapeutic pharmaceuticals for dementia, and settle on a clinical guideline of amyloid imaging.

3. Application of PET techniques for clinical gerontology research and medicine
We apply various PET techniques to gerontology research in understanding normal brain function and its aging, and age related brain disorders. We also provide selected PET diagnostic methods as advanced medical service of the hospital.
