颅脑损伤患者智能和记忆损害的相关因素研究

目的探讨交通事故所致颅脑损伤伤者的智能和记忆损害及相关因素。方法 统计分析成都市1999年1月1日至2001年12月31日间因交通事故造成颅脑损伤的652例伤者的心理测验、脑电图及脑影像学资料。结果研究组平均智商为77.85±15.97,27.9％的伤者智商低于70;51.9％的记忆商低于51。智力损害与文化程度、左颞叶损伤、≥3个脑叶损伤以及脑电图异常明显相关;记忆损害与文化程度、损伤和鉴定检查的间隔时间、脑于损伤、左颞叶损伤、脑电图异常明显相关。结论交通事故造成颅脑损伤的伤者多有不同程度的智力和记忆损害,且与左颞叶损伤、脑电图异常、文化程度、脑干损伤等因素有关。

Clinical analysis on intelligence and memory impairment of patients with brain injury during traffic accident

Objective To study the intelligence and memory impairment of patients with craniocerebral injury during traffic accident and its correlated factors. Method Data of psychological tests, eletroencepa-lograph (EEG) and brain image information of 652 subjects with brain injury who survived from traffic accident in Chengdu from Jan. 1,1999 to Dec. 31,2001 were collected and analysed. Results The average intelligence quotient (IQ) of patients in patients group was 77.85±15.97. 27.9 % patients's IQ was lower than 70. 51.9% patients's memory quotient (MQ) was lower than 51. The intelligence impairment was correlated with education level, left temporal lobe injury, three or more lobes of the brain injuried and EEG abnormality. Memory impairment was correlated with education level, interval between injury and e-valuation, brain stem injury, left temporal lobe injury, and EEG abnormality. Conclusion Impairment of intelligence and memory in different degrees were observed in most patients with traumatic brain injury during traffic accident. Intelligence and memory impairment were correlated with left temporal lobe injury, EEG abnormality, brain stem injury and education level.
