Clinical characteristics and associated factors for depression in patients with Parkinson's disease / 中华老年医学杂志

ABSTRACT

Objective:To investigate the characteristics and associated factors of depression in elderly patients with Parkinson's disease(PD).Methods:A total of 1138 elderly PD patients from Xuanwu Hospital of Capital Medical University were consecutively enrolled.The Hamilton Depression 17-item Scale(HAMD-17)was used to diagnose depression(scores ≥14). The depressive characteristics of PD patients with depression and those without depression were compared, and Logistic regression model was used to analyze the clinical risk factors of depression in PD patients.Results:Among the 1 138 PD patients, 233 cases had depression.The incidence of depression in PD patients was 20.5%, and the treatment rate was only 6.0%(14 cases). The main symptoms of depression in PD patients included sleep disturbance(101 cases, 43.3%), depression(57 cases, 24.5%), work and interest loss(49 cases, 21%). Compared to PD patients without depression, PD patients with depression were more likely women(49.4% vs36.3%), and had lower cognitive scores[(25.56 ± 4.22)scores vs(27.07 ± 3.08)scores], higher rate of freezing of gait(51.0% vs24.0%), higher incidence of disability(87.1% vs28.5%)( P<0.05). A comparison of each part of the unified Parkinson's disease rating scale(UPDRS)between the two groups revealed that the scores of activities of daily living[(16.52 ± 8.71)scores vs(10.15 ± 5.48)scores], the motor examination[(33.78 ± 19.48)scores vs(22.87 ±13.08)scores]and the complications of therapy[2.0(0.0, 6.0)scores vs0.0(0.0, 2.0)scores]were higher in the PD patients with depression group than in the PD patients without depression group( P<0.05). Logistic regression analysis showed that women( OR=1.532, 95% CI 1.073-2.187, P=0.019), disability( OR=6.357, 95% CI 4.399-9.186, P<0.001), activities of daily living evaluated by UPDRS( OR=1.093, 95% CI 1.043-1.146, P<0.001)and motor complications( OR=1.100, 95% CI 1.014-1.193, P=0.022)were independent risk factors for PD depression. Conclusions:Depression was common in PD patients and usually manifested as sleep disturbance and low motivation, women, motor complications, disability and decreased quality of daily living were independent risk factors for depression.
