ABSTRACT

Objective:To investigate the accurrence and related factors of depression in patients with parkinson's disease (PD).Methods:One hundred PD patients with Parkinson′s disease (PD) were enrolled in Department of Neurology in Beijing Hospital from March to June 2019. The depressive mood, sleep status and health-related quality of life of PD patients were evaluated by Beck Depression Scale (BDI), Parkinson′s Disease Sleep Scale 2 (PDSS-2), and 8 items of Parkinson′s Disease Questionnaire (PDQ-8). Spearman correlation analysis and multivariate regression analysis were used to analyze the related factors of PD depression. Nonparametric test was used to analyze the differences between different sleep disorder domains in PD patients with depression.Results:The total score of BDI in 100 PD patients ranged from 0 to 44, with an average of 9.9±8.6 points; the total score of PDSS-2 ranged from 0 to 43, with an average of 12.0±9.2; the total scores of PDQ-8 ranged from 0 to 24, with an average of 6.4±6.0 points. The detection rate of depression in 100 PD patients was 42.0% (42/100), and the total BDI score of 22 patients with mild depression ranged from 10 to 15 with an average of 13.0±1.9; the total BDI score of 14 patients with moderate depression ranged from 16 to 25, with an average of 19.1±3.0; the total BDI score of 6 patients with major depression ranged from 28 to 44 points, with an average of 33.3±6.4. The depression in PD patients was positively correlated with PDQ-8 score ( t=8.908, P<0.01) and PDSS-2 score ( t=2.286, P=0.02); and 85.7% (36/42) of PD patients with depression had sleep disturbance. The score of sleep disturbance domain of PD patients with depression (9.8±3.9) was higher than that of nocturnal motor symptom domain (4.8±4.5) and nocturnal PD non-motor symptom domain (4.1±3.3) ( P<0.01). The scores of emotional health, relationship with loved ones, attention, communication ability dimensions of PDQ-8 were positively correlated with PD depression ( P<0.05). Conclusion:Depression is a common non-motor symptom of PD patients; and PD patients with depression suffer from reduced quality of life and are more prone to sleep disorders.
