To study clinical characteristics and related factors of subjective cognitive decline (SCD)
in patients with Parkinson's disease (PD). Methods: Depending on the presence of SCD, 82 patients with PD
were divided into two groups, the PD-SCD+ group (n=42) and the PD-SCD - group (n=40), to assess cognitive
dysfunction (including attention, executive function, language function, memory function, visual space function,
etc.) and study the clinical characteristics of SCD in PD patients and the relationship between SCD and age,
duration, Hoehn-Yahr grade, and UPDRS score. Results: There was significant difference between PD-SCD+
and PD-SCD - patients in memory (immediate and delayed memory), attention (digital span test and reverse
digital test), and executive function (line test) (t=5.578, P<0.001; t=2.511, P<0.05; t=2.801, P<0.05). Bivariate
correlation analysis showed that SCD in the PD-SCD+ group was negatively related with the severity of disease
condition (H-Y classification), duration, and UPDRS (Part I) score (r=-0.391,P=0.020;r=-0.383,P=0.025;r=
-0.528,P=0.001). No significant difference was observed between PD-SCD+ and PD-SCD- patients in age and
UPDRS (Parts Ⅱ and Ⅲ) score (r=-0.132,P=0.451;r=0.487,P=0.156;r=-0.443,P=0.124). Conclusion:
The patients with PD-SCD had abnormal immediate and delayed memory, and SCD was corelated with course of
disease, disease severity, and UPDRS Part I score. |
