Abstract：Objective To analyze the correlation between transient ischemic attack and mild cognitive impairment. Methods A total of 100 patients with transient ischemic attack who were hospitalized in the Department of Neurology from January 2019 to January 2021 in Hangzhou Fuyang Hospital of Traditional Chinese Medicine were selected as the research group, and 100 healthy subjects during the same period were selected as the control group, the two groups were evaluated for cognitive function, the complete clinical data were collected, the general clinical data and Montreal cognitive assessment (MoCA) score of the subjects in the two groups were recorded, and statistical analysis was performed at the same time. Results There was no significant difference in the general clinical data between the two groups (P＞0.05). The MoCA score of the study group in the first quarter was higher than that in the first week, and the difference was statistically significant (P＜0.05). There was no significant difference in MoCA score between one year and one week in the study group (P＞0.05). The MoCA score of the study group in one year was lower than that in the first quarter, and the difference was statistically significant (P＜0.05). The MoCA scores of the study group for one week and one year were lower than those of the control group, and the differences were statistically significant (P＜0.05). There was no significant difference in MoCA score between the study group and the control group in the first quarter (P＞0.05). In the study group, the Loewenstein occupational therapy cognitive assessment (LOTCA) score in the first quarter was higher than that in the first week, and the LOTCA score in the first year was lower than that in the first quarter, the differences were statistically significant (P＜0.05). There was no significant difference in LOTCA score between one year after illness and one week after illness in study group (P＞0.05). The LOTCA scores of the study group for one week, one quarter and one year were lower than those of the control group, the differences were statistically significant (P＜0.05). The mini-mental state examination(MMSE) score of the study group in the first quarter was higher than that in the first week, the difference was statistically significant (P＜0.05). There was no significant difference in MMSE score between one year after illness and one week after illness in the study group (P＞0.05). The MMSE score of the study group in one year was lower than that in the first quarter, and the difference was statistically significant (P＜0.05). The MMSE scores of the study group for one week, one quarter and one year were lower than those of the control group, and the differences were statistically significant (P＜0.05). Conclusion The MoCA scale was used to evaluate the subjects with transient ischemic attack, and it was found that these subjects had extensive mild cognitive impairment after the disease, it is suggested that attention should be paid to the mild cognitive impairment after transient ischemic attack, in order to carry out early intervention and reduce further harm.
