| Outline of Final Research Achievements |
Development of new treatments for the early prevention of dementia is a pressing issue for the aging society of Japan. We examined the accumulation of amyloid, considered a risk for dementia, by Positron Emission Tomography. In addition, with the use of functional MRI, we evaluated brain function at resting state in Alzheimer’s disease and depression in the elderly. Based on the results, we verified the associated accumulation of amyloid with brain function at resting state, including the default mode network (DMN). Our results showed that amyloid gradually accumulates in persons at risk of dementia. Further, our results demonstrated that patients with depression have functional impairment in the left parietal lobe, whereas those with Alzheimer’s disease are impaired in the right parietal lobe. From these findings, association between the progressive pathology of dementia and brain function at resting state was revealed.
