对神经网络的研究表明,阿尔茨海默病(AD)中发生的健忘症模式可以通过突触丢失来再现,但只有当这种丢失伴随着突触缩放时,突触缩放是一种保持突触后神经元兴奋性输入水平的稳态机制。这表明,在AD的早期阶段增加的胆碱能活性有助于突触缩放和乙酰胆碱酯酶抑制剂改善AD患者的认知,通过提高这一机制。
Studies on neural networks indicate that the pattern of amnesia that occurs in Alzheimer's disease (AD) can be reproduced by synaptic loss, but only when this loss is accompanied by synaptic scaling, a homeostatic mechanism that maintains the level of excitatory input on postsynaptic neurons. It is suggested that increased cholinergic activity during the early stages of AD contributes to synaptic scaling and that acetylcholinesterase inhibitors improve cognition in AD patients by boosting this mechanism.
