Objective To investigate the characteristics of memory impairment in patients with amnestic mild cognitive impairment (aMCI). Methods Thirty-five patients with aMCI and 35 healthy adults matched with age and education level were administered with a neuropsychological battery of tests including conception and perception implicit priming tasks (category exemplar, picture identification), as well as explicit memory tasks (immediate recall, delay recall, delay recognition ). Results Compared with healthy elders, patients with aMCI were impaired in the conception implicit priming task(t=-4.33, P<0.01), as well as in explicit memory (immediate recall, t=6.40, P<0.01;delay recall, t=9.29,P<0.01; delay recognition, t=7.65,P<0.01),but not in perception implicit priming task (t=-0.78, P＞0.05).The conception implicit priming is positively correlated with verbal fluency (r=0.74,P<0.01). Conclusions The present results indicate that patients with aMCI are impaired in both explicit memory and conception implicit priming. The conception implicit priming impairment in aMCI may be related to their frontal lobe dysfunction.
