Outline of Final Research Achievements

Recently, patients with dementia such as Alzheimer type dementia (AD) are increasing. Anesthesia against AD has a possibility of deteriorating cognitive function after surgery. The pathological future of AD is senile plaque due to aggregation of amyloid β (Aβ) and neurofibrillary tangle (microtubule aggregation, Tau abnormal phosphorylation).
In this study, propofol, barbital and midazolam showed little influence on accumulation of Aβ in cultured neurons and mouse brain, whereas ketamine and haloperidol could be promoted. In addition, as a preventive measure, SKF 10047 which is a σ 1 receptor agonist and epigallocatechin were found to promote Aβ degradation. This research provides a clue to the development of safe anesthesia and preventive measures against AD.
