| Research Abstract |
3) We have no autopsy case which have both quantitative rCBF data and neuropathological findings. Subsequently, we have a plan to examine both rCBF and neuropathological findings in autopsy cases.
We present comparative study between regional cerebral blood flow (rCBF) and eye movement, and neuropathology in AD. Additionally, we also present comparative study between alterations in quantitative rCBF and neuropathological findings (Aβ, NFT, neuronal count) in autopsy cases.
1) These AD and three healthy controls (HC) were examined eye-head coordination and rCBF, AD reduced gaze accuracy and head movements, and prolonged the latency of saccade as compared to HC, AD reduced rCBF in the inferior parietal part and visual area. Damage of these areas may have caused eye head coordination disorders in AD.
2) AGEs have been implicated in the chronic complication of DM and play an important role in the pathogenesis of AD. In most senile plaques, AGEs and ApoE were observed together. However, approximately 5% of plaques were AGE positive but Aβ negative. AGEs were mainly present in intracellular NFTs, whereas ApoE was mainly present in extracellular NFTs. In this study suggested that AGE may contribute to eventual neuronal dysfunction and death as an important factor in AD.
