Abstract:

Objective

To investigate the prevalence of early-onset post-stroke cognitive impairment(PSCI) in elderly ischaemic stroke patients and to identifying the influencing factors.

Methods

A crosssectional study was used to randomly include 745 patients admitted the Department of Neurology of Rugao People's Hospital and Taixing People's Hospital from August 2021 to March 2023, who had completed the clinical follow-ups within 3-6 months post-stroke onset.A questionnaire was used to collect basic patient demographics, and disease-related information was collected from the hospital case system, including clinical data, laboratory indicators and imaging data.The National Institute of Health stroke scale (NIHSS)was used to determine the severity of stroke, and the mini-mental state examination (MMSE) was used to assess the cognitive function.Logistic multiple regression analysis was employed to identify factors influencing early concurrent cognitive deficits in elderly ischemic stroke patients.

Results

The prevalence of post-stroke cognitive impairment was 37.99% (283/745) in elderly stroke patients.Risk factors for earlyonset PSCI included Age ≥70 years (OR=2.152, 95%CI: 1.074-5.738), delayed time from onset to clinic visit (OR=2.481, 95%CI: 1.204-4.708), temporal lobe stroke location (OR=2.746, 95%CI: 1.097-7.058),infarct volume ≥1.5 cm3OR=1.992, 95%CI: 1.126-3.523), high carotid plaque score (OR=2.083, 95%CI:1.201-3.613), elevated serum C-reactive protein level (OR=2.893, 95%CI: 1.382-5.739), increased serum homocysteine level (OR=2.847, 95%CI: 1.482-6.382), and high NIHSS score (OR=2.501, 95%CI: 1.592-5.937).

Conclusion

Early-onset PSCI is highly prevalent among elderly stroke patients, with age, time to consultation post-stroke onset, stroke location, infarct volume, carotid plaque score, serum C-reactive protein,serum homocysteine level and NIHSS score identified as significant influential factors.
