Abstract:
Objective Exploring the relationship between the cognitive function level of elderly patients with Parkinson's disease (PD) and malnutrition. Methods A retrospective analysis was conducted on 456 patients with PD admitted to the hospital between April 2021 and April 2025. The nutritional status and cognitive function of patients were evaluated by Mini Nutrition Assessment Short Form (MNA-SF) and Montreal Cognitive Assessment (MoCA). Pearson correlation analysis explored the correlation between MNA-SF score and MoCA total score. Based on the occurrence status of cognitive dysfunction, the patients were classified into cognitive dysfunction group (264 cases) and normal cognitive function group (192 cases). Multivariate logistic regression was utilized to analyze the independent relevant factors of cognitive dysfunction. Results Among the 413 PD patients in this study, the MNA-SF score and total MoCA score were (9.35±2.16) points and (25.26±2.34) points. Pearson correlation analysis indicated that MNA-SF score was positively associated with MoCA total score (r=0.615, P<0.001). Compared with patients in the normal cognitive function group, the patients in the cognitive dysfunction group were older, had shorter years of education, longer PD course, higher proportion of cerebrovascular lesion and lower MNA-SF score (P<0.05). Logistic regression analysis revealed that age, PD course, cerebrovascular lesion and decreased MNA-SF score were independent relevant factors of cognitive dysfunction in elderly PD patients (P<0.05). Conclusion Malnutrition in elderly patients with Parkinson's disease is significantly associated with cognitive impairment, and as an independent factor, it can increase the risk of cognitive dysfunction in these patients.
