普遍认为帕金森病和阿尔茨海默病是两个独立的、有着显著差别的疾病。但是 ,相当数量的证据表明 ,二者具有相互重叠的临床和神经病理特征、相似的病因和病变发生机制。因此 ,现在有人认为这两种疾病的部分病例可能是同一种神经元退行性变疾病的不同表现形式。本文拟对此作一介绍。 It is generally accepted that Parkinson’s disease and Alzheimer’s disease are two separate and significantly different diseases. However, a considerable amount of evidence shows that the two have overlapping clinical and neuropathological features, similar etiologies and pathological mechanisms. Therefore, some people now think that some cases of these two diseases may be different manifestations of the same kind of neurodegenerative diseases. This article intends to make an introduction.
