The Characteristics Of Cognitive Function And Related Risk Factors In Patients With Acute Ischemic Stroke

Objective: To investigate the incidence of cognitive impairment after ischemic stroke(cerebral ischemic stroke), and study the characteristics of epidemiology and imaging and the risk factors of the patients with ischemic stroke.Method:Department were examined by CT or MRI confirmed 313 cases of acute ischemic stroke patients hospitalized in Department of internal medicine in our hospital from January 2014 to January 2015, cognitive impairment after stroke(Post-Stroke Cognitive, Impairment, PSCI) in 191 patients, including post-stroke dementia(Post-Stroke Dementia, PSD) in 106 cases of patients, no dementia after stroke cognitive dysfunction group(Post-Stroke Cognitive Impairment no Dementia, PSCIND) in 85 cases of patients without cognitive impairment(no cognitive, impairment, NCI). 122 cases of patients on admission of patients with the National Institutes of Health Stroke Scale(National Institutes of Health Stroke Scale, NIHSS) score, physical examination record for demographic information, patient history, vascular risk factors, imaging and ultrasound examination information, using the Montreal cognitive assessment scale(Mo CA)- Table Chinese version and the ability of daily living(ADL) on the patients of cognitive assessment, stroke patients after the incident after 3 months of follow-up phone calls and the patients were improved Rinkin scale(modified Rankin Scale(MRS) assessment in patients with functional recovery. The incidence of ischemic stroke patients with cognitive, demographic and imaging features, and its related risk factors is discussed in this paper.Results: 1. The cognitive function scores of the three groups were statistically significant(P < 0.05); The incidence rate of the patients was 61.0%, which in PSD group occurrence rate was 33.8%, PSCIND group occurrence rate was 27.1%, the NCI group occurrence rate was 38.9%, for the first time the PSCI of ischemic stroke occurrence rate was 57.4%, of which the PSD occurred rate was 30.2%, PSCIND incidence was 27.2%; three groups of Mrs score was statistically significant(P < 0.05), ischemic stroke patients 3 months of follow-up, Mrs score mainly concentrated between 0-2, with increasing score, PSD group and PSCIND group the number ratio gradually increased, 5 deletion human death patients. There is only in PSD group.2. PSCI group in the visual space / Executive, language and memory cognitive domain scores were lower than the NCI group, with statistical significance(P < 0.05), the difference was not statistically significant between the two groups(P > 0.05);3. Age, low educational level, hyperlipidemia, recurrent stroke, brain atrophy in PSCI group ratio higher than that in NCI group and had statistical significance(P < 0.05), the differences between the two groups in the rest of the risk factors of no statistical significance(P > 0.05);Conclusions:1 in the Hengyang area, the incidence of cognitive impairment in patients with acute ischemic stroke was 61%, and it had an effect on the life ability of patients after 3 months;2 PSCI is mainly embodied in the visual space / Executive, language, memory and cognitive impairment;3 old age, low education, hyperlipidemia, stroke recurrence, cerebral atrophy is the risk factors of PSCI after acute ischemic stroke.
