Influence factors of depression in patients with lacunar cerebral infarction with mild cognitive impairment / 中国综合临床

ABSTRACT

Objective:To observe the related factors of depression in patients with lacunar cerebral infarction with mild cognitive impairment.Methods:From 2016 to 2019, 114 patients with mild cognitive impairment of lacunar cerebral infarction in Kailuan General Hospital were selected as the research objects.MRI brain scan was completed within 72 hours after admission, and Zung′s self rating Depression Scale (SDS) was used to evaluate emotion within 1 week.According to the results of SDS, 69 patients with mild cognitive impairment and no depression of lacunar infarction were selected as the control group, and 45 patients with mild cognitive impairment and mild depression of lacunar infarction were selected as the case group.The general clinical data, the proportion of patients with lacunar infarction in different brain regions and cognitive function of the two groups were observed.Logistic regression method was used to analyze the risk factors of depression in patients with mild cognitive impairment of lacunar infarction, and the characteristics of clinical somatization symptoms were observed.Results:(1)There were 53 males (76.81%, 53/69) and 16 females (23.19%, 16/69) in the control group, 29 males (64.44%, 29/45) and 16 females (35.55%, 16/45) in the case group, and the difference between the two groups was statistically significant ( P=0.049). Hyperhomocysteinemia in the control group and the case group was 31.88% (22/69) and 53.33%(24/45), respectively, with statistically significant differences between the two groups ( P=0.003). (2) The incidence rates of lacunar infarction in basal ganglia and oval center was 80% (36/45) and 71.11% (32/45) in case group respectively, and 59.42% (41/69) and 18.84% (13/69) in control group respectively.The difference between two groups was statistically significant ( P values were 0.001 and <0.001), and there was no significant difference in infarct size in other regions ( P>0.05). (3) The rate of impaired attention and computing power in the case group was 88.89%(40/45), which was higher than that in the control group 78.26%(54/69), and the difference was statistically significant ( P=0.036). (4) Multivariate Logistic regression analysis showed that hyperhomocysteemia ( OR=2.659, 95% CI 1.041-6.793, P<0.05) and central oval infarction ( OR=10.332, 95% CI 4.069-26.235, P<0.01) were independent risk factors for mild cognitive dysfunction and depression in lacunar cerebral infarction.(5) The proportion of insomnia and tears with somatization symptoms in the case group was 35.56%(16/45) and 37.77%(17/45), respectively, which were higher than that in the control group 8.70%(6/69) and 2.90%(2/69), respectively, with statistically significant differences (all P<0.001). Conclusion:Hyperhomocysteinemia and hemioval central cerebral infarction are independent risk factors for depression in patients with lacunar cerebral infarction with mild cognitive dysfunction, accompanied by somatization symptoms of insomnia and tearing.
