ABSTRACT
It is great value to analyze the pathogenesis of Alzheimer's disease for the formulation and research of prevention and treatment strategies. The change of zang-fu meridians and collaterals is the essential rule of the pathogenesis of internal injury and miscellaneous diseases. Based on the analysis of the physiological basis of the aging changes of zang-fu meridians and the relationship between dementia and the abnormal function of zang-fu meridians and collaterals, this paper systematically explored the relationship between the changes of zang-fu meridians and the pathogenesis of dementia. It is considered that the change of zang-fu meridians and collaterals is the basic law of its pathogenesis development. Therefore, it is proposed that strengthening Qi is the essential principle throughout the whole process of dementia, and dredging channels and collaterals and maintaining normal function of meridians and collaterals are the key to block the pathogenesis evolution of dementia.
