Study On Syndrome Elements of Mild Cognitive Impairment Based on Factor Analysis

Objective：To investigate the syndrome elements of mild cognitive impairment to provide objec- tive evidence for syndrome differentiation and treatment. Methods： 334 patients of mild cognitive impairment were investigated by a predesigned scale. Syndrome elements were summarized with factor analysis. Results：There were 7 common factors picked up by factor analysis. Syndrome elements of disease location were heart, liver, spleen, lung, kidney, and respectively syndrome elements of disease characteristic were essence deficiency, qi deficiency, blood deficiency, yin deficiency, yang deficiency, phlegm, blood stasis, qi stagnation, which was consistent with clinical observation. Conclusion：h is feasible that factor analysis was applied to syndrome ele- ments of mild cognitive impairment, and it was considered that the result can provide objective evidence for syn- dreme differentiation and treatment.
