Analysis of the related factors of insomnia after initial cerebral infarction

Objective To analyze the related factors of initial cerebral infarction. Methods Ninety-eight patients with primary cerebral infarction were selected. They were divided into group A (initial cerebral infarction not complicated by insomnia) of 51 cases, group B (initial cerebral infarction complicated by insomnia) of 47 cases according to whether been compliated by insomia after cerebral infarction. The clinical data of the two groups such as gender, course of disease, age, educational level and the location of infarction were collected. NIHSS scale was used to evaluate the degree of neurological deficit in the two groups; and the related factors of insomnia after initial cerebral infarction were analyzed; Logistic regression analysis was used to analyze the risk factors of insomnia after primary cerebral infarction, the relationship between NIHSS score, educational level and insomnia after initial cerebral infarction was analyzed by Spearman. Results There was a significant difference between the two groups in gender, age, education level, NIHSS score and infarct location (P<0.05). Logistic regression analysis showed that gender, age, educational level, NIHSS score and infarct location were the risk factors of insomnia after initial cerebral infarction (P<0.05). Spearman test showed that there was positive correlation of NIHSS score and educational level with insomnia after initial cerebral infarction (P<0.05). Conclusions Gender, course of disease, age, grade of education, NIHSS score and location of infarction are closely correlated with the occurrence of insomnia after initial cerebral infarction. The risk factors of insomnia after intial cerebral infarction increase with th increasing of educational level and NIHSS score. The above risk factors should be eliminated or reduced in clinical practice to effectively prevent insomnia after primary cerebral infarction.
