Abstract:
Objective To investigate the impact of mild hippocampal atrophy on life quality of patients with Parkinson's disease(PD)and its correlation with cognitive function.Methods A total of 34 PD patients were recruited from Nanjing Brain Hospital,assessed using the Unified Parkinson's Disease Rating Scale(UPDRS),the Parkinson's Disease Questionnaire(PDQ-39)and the Montreal Cognitive Assessment(MoCA),and underwent MRI scans to measure hippocampal volume.Results Compared with the PD without hippocampal atrophy(PD-nHA)group,the PD with hippocampal atrophy(PD-HA)group showed significantly higher age,PDQ-39 total score,and subscores in physical activity,daily living,cognition,and communication dimensions,along with significantly lower MoCA scores,total hippocampal volume,and bilateral posterior hippocampal volume(all P＜0.05).MoCA subdomain analysis revealed that the PD-HA group exhibited varying degrees of decline across visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation domains,although these differences did not reach statistical significance(all P＞0.05).Total hippocampal volume was negatively correlated with PDQ-39 scores in physical activity,cognition,communication,and total score(r=-0.453,P=0.007;r=-0.364,P=0.034;r=-0.355,P=0.039;r=-0.369,P=0.032),and positively correlated with MoCA total score and three cognitive domains:naming,language,and orientation(r=0.408,P=0.017;r=0.348,P=0.044;r=0.406,P=0.017;r=0.355,P=0.039).The PDQ-39 total score was negatively correlated with the MoCA total score(r=-0.468,P=0.005).Compared with baseline,the PD-HA group showed significantly increased PDQ-39 scores(t=2.378,P=0.039)and significantly decreased right anterior hippocampal gray matter volume(t=-2.751,P=0.022)at the final follow-up,while differences in total hippocampal volume and other hippocampal subregions were not statistically significant(all P＞0.05).MoCA scores showed a declining trend but did not reach statistical significance(t=-0.958,P=0.361).In the PD-nHA group,no statistically significant differences were observed in PDQ-39 scores,MoCA scores,or hippocampal volumes between baseline and final follow-up(all P＞0.05).Conclusions Hippocampal atrophy is closely related to cognitive decline and reduced quality of life in PD patients.Particularly,posterior hippocampal atrophy is more closely related to cognitive dysfunction,and cognitive function serves as a mediator between hippocampal atrophy and quality of life.Early interventions targeting cognitive impairment may help improve the quality of life for PD patients.
