Rong FANG ; Shengdi CHEN

Journal of Apoplexy and Nervous Diseases.2024;41(5):387-394. doi:10.19845/j.cnki.zfysjjbzz.2024.0076

Post-stroke cognitive impairment(PSCI)has attracted substantial attention in the field of stroke research worldwide due to its high incidence rate and significant morbidity and mortality rates,but there are limited treatment meth-ods since the pathogenesis of PSCI remains unclear.Clinical observational studies have shown that patients achieve vary-ing degrees of cognitive recovery within the first 12 months after stroke,and such recovery is closely associated with the mechanisms of neuroplasticity.Gaining a deeper insight into the mechanisms of neuroplasticity is important for developing optimal strategies for nervous system repair after stroke and compensating for impaired brain functions.This article intro-duces the mechanisms of spontaneous neuroplasticity after stroke,including the plasticity of neuronal cells,synaptic neu-ral circuits,and brain networks,and their association with cognitive function and reveals the dynamic and intricate nature of neuroplasticity and brain function recovery.Subsequently,the article discusses the treatment methods for enhancing neuroplasticity,including pharmacotherapy,rehabilitation training,and noninvasive brain stimulation,and points out that early intervention may help to achieve a good outcome.Although there is a lack of clear clinical evidence for some new methods,inspiring results have been obtained in preliminary studies,which may help to initiate a new era in post-stroke therapy.

Zhiyue WU ; Xiaofan XUE ; Anqi HUANG

Journal of Apoplexy and Nervous Diseases.2024;41(5):408-412. doi:10.19845/j.cnki.zfysjjbzz.2024.0079

Objective To establish the delimitation norm of cognitive domain assessment scales for Parkinson dis-ease(PD)in Beijing,China,and to investigate the optimal cut-off values for determining abnormal neuropsychological as-sessments.Methods A total of 33 normal middle-aged and elderly individuals in communities and 89 patients with non-dementia PD were included in this study,and all subjects underwent global cognitive function screening and cognitive do-main assessments.According to whether Montreal Cognitive Assessment(MoCA)score was greater than 25 points,the pa-tients with PD were divided into mild cognitive impairment group(PD-MCI group)and normal cognition group(PD-NC group).In order to compare the consistency between PD-related cognitive domain assessment scales and global cognitive function screening in the diagnosis of PD-MCI,different cut-off values below the appropriate norms(i.e.,1.00 standard deviation,1.28 standard deviations,1.64 standard deviations,1.96 standard deviations below the mean)were examined for sensitivity,specificity,positive predictive value,and negative predictive value to obtain the optimal cut-off value.Results The delimitation norm of PD-related cognitive domain assessment scales was established for Beijing,and the re-sults showed that 1.96 standard deviations had the highest consistency in the diagnosis of PD-MCI and PD-NC,with the best sensitivity and specificity.Conclusion This study establishes the delimitation norm of PD-related cognitive domain assess-ment scales and fills the blank of the unbounded value of most domestic PD cognitive impairment assessment scales,and it also proposes the optimal cut-off value of abnormal neuropsychological assessment,which provides a reference standard for the cognitive domain assessment of PD patients in China and helps clinicians to identify cognitive decline in PD patients and adopt intervention measures in the early stage.
