基于"因加而发"和"既病防变"理论探讨卒中后认知障碍的防治OA

Based on the theories of "onset due to accumulated pathogenic factors"and"preventing Disease progression",this paper explores the prevention and management strategies for post-stroke cognitive impairment(PSCI).The pathogenesis of PSCI is fundamentally characterized as deficiency in root while excess in manifestation:visceral insufficiency acts as the root cause,while latent pathogens triggered by newly invading pathogenic factors act as the manifestation.The struggle between healthy Qi and pathogenic factors eventually leads to dysfunction of mental spirit.Based on the theory of "onset due to accumulated pathogenic factors",PSCI is related to combined internal and external pathogenic factors,alongside the dynamic evolution of deficient Qi and excessive pathogens.The theory of "preventing disease progression" emphases staged intervention strategies:resolving phlegm and removing blood stasis in the acute phase to halt disease aggravation;tonifying the kidney and replenishing essence during the convalescent phase to consolidate the body's foundation;and applying concurrent purgative and tonifying therapy in the sequela phase to prevent pathological progression and deterioration.This staged therapeutic strategies can offer a reference for postponing the progression of PSCI.
