A comparative study on the clinical characteristics of senile Parkinson's disease with depression and unipolar depression in older adults / 中华老年医学杂志

ABSTRACT

Objective:To explore the difference of clinical characteristics between senile Parkinson's disease(PD)with depression and unipolar depression.Methods:From March 2019 to March 2020, 53 patients with Parkinson's disease depression and 57 patients with unipolar depression who were admitted to the neurology department of Beijing Hospital were continuously collected.The gender, age and education level of the patients were recorded.The course of disease and other general data of the patients with Parkinson's disease were also recorded.Depression and anxiety of the patients were evaluated by Beck Depression Inventory(BDI)and Generalized Anxiety Disorder Scale(GAD-7). Quality of life of patients with Parkinson's disease was evaluated by 8-item Parkinson's disease questionnaire(PDQ-8). Differences in the assessment results and quality of life scores between the two groups were analyzed.Results:The incidence of depression comorbid with anxiety in elderly PD patients was 52.8%(28/53), lower than that in elderly unipolar depression patients comorbid with anxiety [84.2%(48/57)]( χ2=12.664, P<0.001). The scores of activity inhibition [(1.8±0.8)points]and hyposexuality [(0.4±1.0)points]in elderly PD patients with comorbid depression were higher than that in patients with unipolar depression [(1.1±0.8)points, (0.0±0.0)points]( t=4.399, 2.942, P<0.001, =0.005). Moreover, the incidence of activity inhibition(98.1%)and hyposexuality(15.1%)in PD patients with comorbid depression was higher than that in patients with unipolar depression(78.9%, 0.0%)( χ2=9.680, 9.279, both P=0.002). The scores of self-blame [(1.0±0.8)points]and pain [(1.0±0.8)points]in elderly patients with unipolar depression were higher than those in PD patients with comorbid depression [(0.5±0.7)points, (0.9±0.7)points]( t=-3.902, -2.486, P<0.001, =0.014). Moreover, the incidence of self-blame(66.7%), irritability(78.9%)and image distortion(56.1%)in elderly patients with unipolar depression was higher than that in PD patients(35.8%, 56.6%, 35.8%)( χ2=10.447, 6.320, 4.547, P=0.001, 0.012, 0.033). The scores of PDQ-8 in PD patients with comorbid depression and anxiety [14.8(10.8, 19.0)points]( Z=-3.544, P<0.001)were higher than those in PD patients with depression only [7.0(4.8, 11.0)points]. Conclusions:The focus of depression in elderly PD patients is different from that in elderly unipolar depression patients.Elderly patients with unipolar depression are more likely to be comorbid with anxiety.Depression reduces the quality of life in PD patients, and the comorbidity of anxiety further reduces the overall quality of life in PD patients with depression.
