Objective: To explore the correlation between the degree of neurological deficits and cognitive impairment and to analyze the strategic infarct location and the characteristics of cognitive impairment. Methods: A total of 151 patients with single-site cerebral infarction were selected, and the degree of neurological deficit was assessed by the National Institutes of Health Stroke Scale (NIHSS). The Montreal Cognitive Assessment (MoCA) was used to assess cognitive function. According to the MoCA score, the patients were divided into 104 cognitive impairment groups and 47 non-cognitive impairment groups. According to the results of imaging examination, 30 patients with cognitive dysfunction were divided into basal ganglia group, 11 in thalamus group, 13 in frontal lobe group, 10 in temporal lobe group, 9 in occipital lobe group, 10 in parietal lobe group, 10 in brainstem group and 11 in cerebellum group. Results: There was no significant difference in the age, gender, years of education and NIHSS score between the cognitive impairment group and the non-cognitive impairment group at admission (P> 0.05). The visual space and executive function scores of thalamus, frontal, temporal, and occipital lobe groups were lower (P< 0.05). The temporal lobe group had a lower naming function score (P< 0.05). The scores of attention function in thalamus and frontal lobe group were lower (P< 0.05). The score of language function in thalamus group was low (P< 0.05). Delayed recall function scores were lower in thalamus, frontal, and temporal lobe groups (P< 0.05). The scores of directional function in thalamus, frontal and temporal lobe were lower (P< 0.05). The cognitive function scores in basal ganglia, parietal lobe, brainstem, and cerebellum were not statistically significant (P> 0.05). After 3 months, there were no significant differences between the treatment group and the control group in terms of naming, delayed recall, and orientation (P> 0.05). The treatment group had higher scores in visual space performance, attention, language, and abstract function (P< 0.05). Conclusion: There is no significant correlation between the severity of neurological deficits and cognitive impairment in patients with stroke. The strategic infarct location leading to cognitive dysfunction are: thalamus, frontal lobe, temporal lobe, occipital lobe. Cognitive impairment domains in patients with thalamic infarction are visual space and executive function, attention, language, delayed recall, and orientation function. The domain of cognitive impairment in frontal lobe infarction is visual space and executive function, attention, delayed recall, and orientation function. The domain of cognitive impairment in patients with temporal lobe infarction is visual space and executive function, naming, delayed recall, orientation function. Occipital cognitive impairment domain for visual space executive function.
