Abstract:
Objective Cognitive impairment represents a notable feature of depressive disorders. Comprehending its characteristics and influencing factors is vital for patient rehabilitation. Methods This study is based on the 2015 Shandong Province epidemiological survey of mental disorders, from which 871 individuals meeting DSM-IV criteria for depressive disorders were selected as the research group. Using 1:1:1 matching by sex, age, and residence, we randomly selected 825 individuals with no DSM-IV diagnosis but positive on GHQ-12 and additional risk assessments as the elevated risk control group, and 825 with negative screenings as the minimal risk control group. In 2020, a follow-up survey was conducted, resulting in a final analysis of 1,855 cases. The survey included demographic data, various clinical information, and a series of screening and questionnaire assessments. Results The current depressive group scored lower on the MoCA than the non-depressive group ( t =8.86, P <0.01). The research group scored lower on the MoCA than the elevated and minimal risk group ( F =11.98, P <0.01). The depression-unremitted group scored lower than the depression-remitted group ( t =6.44, P <0.01). The Analysis indicated that males, with better life quality, poor early psychological status and, and longer education were associated with higher MoCA scores. Conversely, older age, rural residency, employment, current depression, and poor marital were associated with lower MoCA scores. Conclusion Individuals with depression commonly suffer cognitive impairment, which tends to partially improve as depression remits. Individual cognitive function is influenced by early psychological health, depressive status, quality of life, age, sex, educational level, residence, occupational, and marital status.Keywords:

Our aim was to compare the utility and accuracy of the Chinese Version of Montreal Cognitive Assessment Basic (MoCA-BC) and the Montreal Cognitive Assessment-Beijing Version (MoCA-BJ) in the identification of mild cognitive impairment (MCI) under different education levels. A sample of individuals with MCI (n = 295), Alzheimer's disease (AD; n = 254), and normal controls (NC; n = 259) at 2 Memory Clinics and communities was administered the MoCA-BC, MoCA-BJ, Mini-Mental State Examination (MMSE), and other neuropsychological tests. The discriminant validity of the MoCA-BC and MoCA-BJ as diagnostic instruments was ascertained. The overall discriminant validity for detection of MCI from NC (receiver operating characteristic area under the curve [95% confidence interval]) was that the MoCA-BC (0.95 [0.93, 0.97]) had better sensitivity and accuracy than MoCA-BJ (0.87 [0.84, 0.90]). In addition, we provide an easy to use table that enables the conversion of MoCA-BC to the MoCA-BJ scores or to MMSE scores. The MoCA-BC and MoCA-BJ provided good diagnostic accuracy when compared to MMSE. The MoCA-BC, which was proved to be an appropriate tool when screening for MCI among elderly subjects, can now be compared directly with the MoCA-BJ.

The Montreal Cognitive Assessment (MoCA) is one of the most common screening instruments for mild cognitive impairment. However, the standard MoCA is approximately two times longer to administer than the Mini-Mental State Examination. A total of 699 Czech and 175 American participants received the standard MoCA Czech and English versions and in the clinical part, a sample of 102 nondemented patients with Parkinson's disease (PD). We created a validated Czech short version (s-MoCA-CZ) from the original using item response theory. As expected, s-MoCA-CZ scores were highly correlated with the standard version (Pearson

Objective To study the effect of Motreal cognitive assessment(MoCA)(Chinese version) in diagnosing the amnestic mild cognitive impairment.Methods A total of 61 persons were chosen from the outpatient section of Beijing Hospital(2009-05-2010-03),including 31 patients who meeting the criteria of MCI-Revised(MCI-R) and 30 normal controls(NC) for comparing the sensitivity and specificity of the mini-mental state examination(MMSE) and MoCA in diagnosing the aMCI and analysing the effect and characteristics of MoCA in diagnosing the aMCI.Results When using the cut off score of 26,the sensitivity of MMSE and MoCA are 9.68% and 87.10% separately,the specificity are 93.33% and 73.33%.Conclusions MoCA might play an important role in screening aMCI and the other cognitive impairments due to the better sensitivity of MoCA and its wide cover of multiple cognitive district.

The Montreal Cognitive Assessment (MoCA) is known to have discriminative power for patients with Mild Cognitive Impairment (MCI). Recently Cognitive Reserve (CR) has been introduced as a factor that compensates cognitive decline. We aimed to assess whether the MoCA reflects CR. Furthermore, we assessed whether there were any differences in the efficacy between the MoCA and the Mini-Mental State Examination (MMSE) in reflecting CR. MoCA, MMSE, and the Cognitive Reserve Index questionnaire (CRIq) were administered to 221 healthy participants. Normative data and associated factors of the MoCA were identified. Correlation and regression analyses of the MoCA, MMSE and CRIq scores were performed, and the MoCA score was compared with the MMSE score to evaluate the degree to which the MoCA reflected CR. The MoCA reflected total CRIq score (CRI; B = 0.076, P < 0.001), CRI-Education (B = 0.066, P < 0.001), and CRI-Working activity (B = 0.025, P = 0.042), while MMSE reflected total CRI (B = 0.044, P < 0.001) and CRI-Education (B = 0.049, P < 0.001) only. The MoCA differed from the MMSE in the reflection of total CRI (Z = 2.30). In this study, we show that the MoCA score reflects CR more sensitively than the MMSE score. Therefore, we suggest that MoCA can be used to assess CR and early cognitive decline.

The Montreal Cognitive Assessment （MoCA） は軽度認知障害のスクリーニング検査であり，合計得点の算出時に教育年数を考慮する特徴がある。先行研究では，MoCAの下位指標の一つである言語領域得点において教育年数の影響が報告されているが，日本においてMoCAの各認知領域得点と教育年数との関連は明らかになっていない。そこで本研究では，教育年数がMoCAの各認知領域に与える影響を評価するため，60歳以上の健常高齢者104名に対し日本語版MoCAおよび教育年数の聴取を行い，教育年数で2群（低群：12年以下，37名；高群：13年以上，67名）に分け，各認知領域得点についてWelch’s t-testを行った。その結果，先行研究で報告されている言語領域得点（t（76.0）＝－2.114, p＝0.038）に加え，注意領域得点（t（62.8）＝－2.075, p＝0.042）においても，教育年数高群の方が低群よりも有意に高かった。以上より，日本では教育年数がMoCAの言語領域だけでなく注意領域にも影響を与えることが示唆された。

The Montreal Cognitive Assessment (MoCA; Nasreddine et al., JAGS 2005) is a brief measure of global cognitive function used worldwide and validated as a reliable tool for the detection of cognitive impairment in several neurodegenerative diseases and medical conditions. Our objective was to investigate the validity of the German MoCA alternate forms for the purpose of longitudinal clinical and research applications.
