阿尔兹海默症的机理

The pathology of Alzheimer's disease is characterized by the accumulation of abnormal proteins in the brain, including beta-amyloid plaques and neurofibrillary tangles, as well as abnormal synaptic function and neuron loss. These pathological changes lead to impairments in memory, thinking, judgment, visual spatial recognition, and emotion, among other cognitive functions.

阿尔兹海默症的病理学特征是脑内细胞外老年斑沉淀和神经细胞内原纤维缠结和神经元突触功能异常，神经元大量丢失。这些病理变化导致记忆、思维、判断、视觉空间识别和情感等认知功能出现障碍。
