Background Amnestic mild cognitive impairment (aMCI) is highly likely to progress to dementia of the Alzheimer type (DAT). One of the most frequently reported symptoms in aMCI and DAT patients is memory impairment. This study compared the levels of beliefs about memory efficacy and control, cognitive activity, and depression among healthy older adults (OA), patients with aMCI, and patients with DAT. Methods This study included 21 OA (11 males, 10 females), 16 aMCI patients (6 males, 10 females), and 18 DAT patients (10 males, 8 females). The memory efficacy questionnaire, memory control questionnaire, cognitive activity questionnaire, depression questionnaire, and Seoul Verbal Learning Test were administered to all subjects. Results DAT patients showed significantly lower scores on the recognition test than did the OA and aMCI patients, and no difference in these scores was observed between the OA and aMCI patients. Regarding the memory efficacy, memory control, and cognitive activity questionnaires, DAT and aMCI patients showed significantly lower scores than did OA. However, there were no differences in these scores between aMCI and DAT patients. Conclusion The results of this study suggest that aMCI patients experienced impairment in memory beliefs and memory control in the same way as DAT patients did. These results suggest that the early application of cognitive rehabilitation therapy for patients with aMCI may be effective in preventing or alleviating memory deterioration.
