Epidemiology and Risk Factors Characteristics of Alzheimer’s Disease in Southwestern China: A Cross-Sectional Study

Elderly individuals in southwestern China exhibit a high prevalence of cognitive impairment, with AD associated with complex risk factors including established contributors like advanced age, dementia family history, alcohol abuse, and multisystem comorbidities-while notably identifying surgical history and urolithiasis as region specific risk signals. These findings underscore regional, environmental, and ethnic influences on AD pathogenesis, requiring tailored prevention/treatment. Future priorities include integrating brief cognitive screening into primary care, targeting high-risk groups (eg, undereducated rural elderly women), and establishing prospective cohorts to clarify causal links between urolithiasis, surgical history, and cognitive decline for refined region-adapted AD prevention.
