Background:
Post-stroke cognitive impairment (PSCI), a common complication following stroke, significantly impacts patients' quality of life and prognosis. Research indicates that neuroregulation and protein metabolic disorders play crucial roles in the development of PSCI.
Purpose:
This study aimed to evaluate the reliability of the Regional Meningoarterial Score (rLMC) in determining collateral circulation status in acute ischaemic stroke patients.
Method:
Participants were selected based on specific criteria including MRI-detected recent cerebral infarction, absence of prior large-scale subcortical infarction or haemorrhage, and no history of Alzheimer's disease or cognitive impairment.
Results:
The results showed that cognitive impairment group (CI group) exhibited significantly lower serum acetylcholine levels compared to normal control group (CN group), while β-amyloid protein levels were markedly higher. CI group also demonstrated reduced expression of neuroregulatory factors.
Conclusion:
These findings demonstrate that neuroregulatory factors and protein metabolites can serve as potential biomarkers for early diagnosis and intervention, effectively predicting post-stroke cognitive impairment.
