目的　探讨老年人脑代谢显像与记忆、智力的关系 ,为神经心理测验与脑代谢显像结合评估脑功能积累经验。方法　自述记忆下降的老年人 3 5例 ,全部作1 8F FDGSPECT符合线路、MR、韦氏记忆、瞬时 /延时记忆测验以及简易智力精神状态检查。按脑代谢正常及损害程度分为 3组 ,比较各组记忆、智力差异。结果　三组的瞬时 /延时记忆测验、1分钟遗忘率以及MQ >90例数均显示代谢损害组的成绩较差 (P <0 0 1,P <0 0 5 ) ,MMSE差别不明显 (P >0 0 5 )。结论　大脑糖代谢状况与记忆测验成绩呈正相关关系。记忆功能较智力对大脑糖代谢损害更为敏感。 Objective To explore the relationship between brain metabolic imaging and memory and intelligence in the elderly and to evaluate the accumulation of brain function for the combination of neuropsychological tests and brain metabolism imaging. Methods Thirty-five elderly patients with decreased self-reportmemory were enrolled in this study. All of them were examined by 18 F FDGSPECT, MR, Webster’s Memory, Instantaneous / Delayed Memory Test and Simple Mental Status Examination. By normal brain metabolism and the degree of damage is divided into 3 groups, comparing the memory, mental differences. Results The instantaneous / delayed memory test, 1-minute forgetting rate and MQ> 90 cases showed that the scores of metabolic impairment group were significantly lower (P <0.01, P <0.05), and the difference of MMSE was not significant > 0 0 5). Conclusion There is a positive correlation between brain glucose metabolism status and memory test results. Memory is more intellectual than brain damage to glucose metabolism more sensitive.
