摘要
2型糖尿病(type 2 diabetes mellitus，T2DM)是一种复杂而异质的代谢紊乱，可导致不同程度的胰岛素抵抗和B细胞功能障碍。胰岛素抵抗与认知功能障碍之间存在明确的联系，而认知功能障的终点为阿尔茨海默病(Alzheimer’s disease，AD)。因此，AD和T2DM之间的关键交叉点可能是胰岛素抵抗。胰岛素抵抗显著影响海马可塑性，改变淀粉样蛋白前体蛋白(amyloid precursor protein，APP)代谢，增加tau蛋白浓度，并改变脑组织结构。

Abstract
Type 2 diabetes mellitus (T2DM) is a complex and heterogeneous metabolic disorder that leads to varying degrees of insulin resistance and B cell dysfunction. There is a clear link between insulin resistance and cognitive impairment, which ends in Alzheimer’s disease (AD). Therefore, the key crossover point between AD and T2DM may be insulin resistance. Insulin resistance significantly affects hippocampal plasticity, changes amyloid precursor protein (APP) metabolism, increases tau protein concentration, and changes brain tissue structure.
