ObjectiveThis study aims to investigate the effect of folate combined with VitB12 on serum total homocysteine (tHcy) levels and cognitive function in patients with mild cognitive impairment (MCI) complicated by hyperhomocysteinemia (HHcy).Methods(1) A total of 92 MCI patients with HHcy were enrolled in this study and randomly divided into two groups: the intervention group (46 cases) and the control group (46 cases). (2) The patients in both groups received the routine treatment for their condition, but patients in the intervention group were also given 5 mg/day of folate and 500 μg × 3/day of VitB12. (3) The changes in levels of folate, VitB12, and tHcy, the Montreal Cognitive Assessment (MoCA) score and the event-related potential (P300) were observed before and after treatment.Results(1) There were no statistically significant differences in folate, VitB12, and tHcy levels, the MoCA score and the P300 between the two groups before treatment. (2) At the 4th, 12th and 24th week, folate and VitB12 levels in the intervention group were higher than those in the same group before treatment and those in the control group at the same time points, while tHcy levels were lower than those in the same group before treatment and those in the control group at the same time points. (3) At the 24th week, the MoCA score in the control group was lower than before treatment, and the MoCA score in the intervention group was higher than in the same group before treatment and in the control group at the same time point. The P300 latency was shorter than it was in the same group before treatment and in the control group at the same time point.ConclusionFolate and VitB12 can effectively reduce levels of tHcy in patients with MCI and improve cognitive function. 相似文献

Introduction: Self-estimation of performance implies the ability to understand one’s own performance with relatively objective terms. Up to date, few studies have addressed this topic in mild cognitive impairment (MCI) patients. The aim of the present study was to compare objective measures of performance with subjective perception of specific performance on cognitive tests and investigate differences in assessment between MCI patients and healthy elderly. Method: Thirty-five participants diagnosed with MCI (women = 16, men = 19, mean age = 65.09 years ±SD = 7.81, mean education = 12.83 years ±SD = 4.32) and 35 control subjects similar in terms of age and education (women = 20, men = 15, mean age = 62.46 years ± SD = 9.35, mean education = 14.26 ± SD = 2.84) were examined with an extended battery of neuropsychological tests. After every test they were asked to self-evaluate their performance by comparing it to what they considered as average for people of their age and educational level. This self-evaluation was reported on a scale ranging from –100 to +100. Results: Significant differences were found in the self-assessment patterns of the two groups in memory measures of verbal and visual delayed recall, visuospatial perception, and tests of attention. MCI patients overestimated their performance on every cognitive domain while control participants underestimated their performance on measures of verbal memory. Conclusions: The present results indicate that accuracy of self-report is not uniform across groups and functional areas. The discrepancies in the MCI patients indicate unawareness of their memory deficits, which is contradictory to subjective memory complaints as being an important component for clinical diagnosis. 相似文献

Mild cognitive impairment (MCI) is considered as a potential transitional state between normal aging and dementia. Studies addressing semantic memory in patients with incipient dementia and MCI show inconsistent results. In the current report we focused on MCI and examined memory performance (semantic, episodic, and working memory) in addition to structural and functional magnetic resonance imaging (fMRI) measurements. We studied 6 MCI, 6 normal controls, and 4 Alzheimer disease (AD) patients. MCI participants demonstrated normal semantic memory performance while fMRI examination revealed distinct patterns of activations between MCI and normal aged subjects. According to our previous study, time courses were taken from parietal, dorsolateral‐prefrontal‐cortex (DLPFC), hippocampal formation, and fusiform gyri. A small number of activated voxels in parietal regions were depicted in MCI participants and were correlated with structural changes in this region. In contrast, significantly higher activation (intensity and number of voxels) was observed in DLPFC of MCI subjects. The overactivity seen in DLPFC of MCI may represent a compensatory mechanism that enables them to perform normally. These preliminary results suggest that functional imaging may be useful for early diagnosis of dementia and call to develop reliable tests and criteria that will enable using such methods clinically. 相似文献

ABSTRACT This study aimed to identify predictors of learning and adherence to a previously validated compensatory calendar and note-taking system (Memory Support System; MSS) in persons with amnestic mild cognitive impairment (aMCI). Age, education, global cognition, depression, and memory-related self-efficacy were studied as predictors of individuals’ ability to learn the use of the MSS during the two-week training and of their adherence to the MSS 6, 12, and 18 months after training. How well an individual was able to learn the use of the MSS was itself examined as a predictor of adherence. Two-hundred-and-fifteen older adults with aMCI and their study partners (e.g., spouse, adult child) received MSS training one-hour daily for 10 days. Ordinal logistic regression analyses indicated that (1) global cognition predicted MSS learning at end of training, and (2) MSS learning at end of trainng predicted MSS adherence at 6, 12, and 18 months post-training. The current study suggests that offering compensatory strategies as early as possible for those with MCI might be of most benefit, and might have implications for long-term adherence. 相似文献
