Characteristics and Related Factors of Cognitive Impairment for Severe Traumatic Brain Injury / 中国康复理论与实践

ABSTRACT

Objective:To investigate the characteristics of cognitive impairment of patients with severe traumatic brain injury (TBI) and to analyze the related factors. Method:From September, 2015 to September, 2017, 94 patients surviving from severe TBI were assessed with Montreal Cognitive Assessment (MoCA), and their baseline data were recorded in detail. Results:The scores were lower in the recall, abstraction, verbal fluency, visual executive and attention of MoCA, and higher in naming, digit span, orientation and calculation. The scores in total, attention, abstraction and recall were lower in patients with frontal lobe injury than those with basal ganglion injury. The scores in total, naming, abstraction and recall were lower in patients with frontal-temporal-parietal lobes injury than those with basal ganglion injury. Multivariate regression showed that the time of coma and the location of injury were the related factors to the total score of MoCA (P < 0.05). Conclusion:Cognitive impairment after TBI demostrates commonly in many aspects, which are related with the time of coma and the area of injury.
