This study investigated whether the MoCA index scores represent the functions of each cognitive domain by examining the correlations with the corresponding cognitive domain scores derived from conventional neuropsychological tests included in the Seoul Neuropsychological Screening Battery, 2nd Edition (SNSB-II). Methods The participants were 104 amnestic mild cognitive impairment (aMCI), 74 vascular mild cognitive impairment (VaMCI), 73 dementia of the Alzheimer's type (DAT), and 41 vascular dementia (VaD) patients. All participants were administered the Korean-MoCA and SNSB-II. Results Like the MoCA total score, the MoCA-OIS, MoCA-VIS, and MoCA-MIS showed differences between aMCI and AD groups and between VaMCI and VaD groups. The MoCA-AIS, MoCA-LIS, and MoCA-EIS showed significant differences between VaMCI and VaD groups, but no difference between aMCI and DAT groups. In the aMCI and VaMCI groups, all index scores of the MoCA showed significant correlations with the corresponding cognitive domain scores of the SNSB-II. Except for MoCA-MIS, the MoCA-AIS, MoCA-LIS, MoCA-VIS, and MoCA-EIS also showed significant correlations with the corresponding domain scores of the SNSB-II in the DAT and VaD groups. Conclusions These results indicate that all MoCA index scores, except for MoCA-MIS, which does not reflect the severity of memory impairment in dementia patients, provide highly valid information on the function of each cognitive domain in patients with mild cognitive impairment and dementia.","PeriodicalId":72779,"journal":{"name":"Dementia and neurocognitive disorders","volume":"20 3","pages":"28-37"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/87/8c/dnd-20-28.PMC8326308.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39280695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dementia patients are among the most vulnerable individuals in the society, and the COVID-19 crisis has further worsened their susceptibility. Notably, most of them are elderly patients who are vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19 complications.2,3 In order to prevent the spread of SARS-CoV-2 infection, most governments imposed mitigation measures including quarantine and movement restrictions. This confinement significantly limits physical, cognitive, and social activities and has consequently led to the rapid deteriorating of clinical symptoms in dementia patients.4 In addition, confinement is associated with several psychological effects, including depression, irritability, and anger, which are likely to have a negative impact on the already burdened caregivers both at home and nursing facilities. The Korean Dementia Association has been very concerned about the consequences of the pandemic on dementia patients and their families and has come up with two measures aimed at developing a strong support system; 1, developing care guidelines for dementia patients and caregivers, and 2, Conducting a survey to identify the extent of COVID-19 impact in dementia patients.

However, in neurodegenerative diseases such as Alzheimer's disease (AD), the NSCs are damaged as well. Glia-like cells from human mesenchymal stem cells (ghMSCs) are functionally enhanced adult stem cells. In the present study, we investigated whether ghMSCs could protect NSCs from amyloid beta (Aβ)-mediated toxicity.Methods: Rat NSCs were obtained from E13-14 fetal rat cortices. NSCs were seeded in pre-coated plates, and the next day, cells were simultaneously treated with 20 μM Aβ and 0.4 μm pore insert well-seeded ghMSCs. After 48 hours of co-treatment, cell viability and proliferation were evaluated. After 2 hours of co-treatment, western blotting was performed to measure inflammasome-related factors, such as NOD-like receptor family pyrin domain containing 3, caspase-1, and interleukin-1β.Results: The results showed that ghMSCs increased viability and proliferation and reduced the toxicity of NSCs injured by Aβ by reducing the NRLP3 inflammasome activation of NSCs induced by Aβ.Conclusions: In this study, we confirmed that ghMSCs could protect NSCs in an in vitro model of AD through the regulation of inflammatory response.","PeriodicalId":72779,"journal":{"name":"Dementia and neurocognitive disorders","volume":"20 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/c6/5f/dnd-20-1.PMC7847801.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25341903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data used in this study were obtained from the Alzheimer's disease (AD) Neuroimaging Initiative study. Brain atrophy was assessed by CVRS using MRI. AT(N) profiles were classified by cerebrospinal fluid abnormality. Based on the AT(N) assessment, all individuals in this study were divided into 3 groups (normal state biomarker, suspected non-Alzheimer's pathology [SNAP], or Alzheimer's continuum). The cox regression was used to analyze the hazard ratios of CVRS for progression to dementia.Results: Sixty-three progressed and 238 remained stable to dementia and the CVRS (mean±standard deviation) had significant difference between progressive MCI and stable MCI (p<0.001). Univariate and multivariate cox regression results (p<0.001) showed the independence of initial CVRS as a predictor for the progression to dementia. Moreover, comparing the classified AT(N) pathology group, SNAP and AD, effectiveness of CVRS as a predictor was verified only in Alzheimer's continuum.Conclusions: The initial CVRS score as a predictor of dementia progression was independently validated at the stage of Alzheimer's progression among AT(N) pathologically differentiated MCI.","PeriodicalId":72779,"journal":{"name":"Dementia and neurocognitive disorders","volume":"19 4","pages":"129-139"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/66/f8/dnd-19-129.PMC7781734.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38763849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
