The study on the implicit memory in patients with Alzheimer disease / 中国神经精神疾病杂志

ABSTRACT

Objective To explore the characteristics of conceptual priming and perceptual priming in patients with Alzheimer's disease (AD). Methods The implicit memory (conceptual repetition priming and perceptual repetition priming) and Neuropsychological (DS, VFT, CTT interference time) tests were conducted on 30 aMCI patients, 30 AD patients and 30 normal elderly people. Results Compared with the normal elderly group and the aMCI group, DS, VFT, CTT interference time and conceptual repetition priming of AD patients were lower than those in the normal elderly group (P<0.01). However, perceptual repetition priming was no statistically significant among the groups (P>0.05). Conclusion AD patients have impairments on the conceptual repetition priming , DS, VFT, CTT interference time and implicit memory and the decrease in the frontal lobe function may be an important neurological basis for AD.
