To clarify the mechanisms of aging and age-related disorders such as dementia, develop methods for early diagnosis, and explore the regeneration of brain functions using brain imaging (PET/SPECT, MRI, MEG, etc.). Clarifies the characteristics of disorders related to Alzheimer's disease using brain imaging, and establishes the scientific evidence to diagnose very early Alzheimer's disease based on high-level clinical trials. Clarifies functional and morphological changes of the brain in normal aging and neurological disorders such as Alzheimer's disease to promote early diagnosis and treatment. Develops diagnostic methods(such as novel radiopharmaceuticals) for PET in research on aging and age-related disorders such as dementia, and performs basic evaluation in experimental animals as well as clinical application of the methods. Note： PET (positron emission tomography)/SPECT (single photon emission computed tomography): Technologies that visualize distribution of radiopharmaceutical which shows brain functions; MRI (magnetic resonance imaging): A technology that visualizes the morphology and functions of the brain by means of technologies of magnetic resonance; MEG (magnetoencephalography): A technology to visualize brain functions by detecting faint magnetic fields created by cortical neurons. back to index
