One hundred healthy subjects (67 illiterates and 33 semi-illiterates) participated in this study. None of the participants had serious medical, psychiatric, or neurological disorders including dementia. The protocol included the administration of three components of the 10/66 Dementia Research Group cognitive test battery;Community Screening Instrument for Dementia (CSI “D”, generating the COGSCORE measure of global function), and the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) verbal fluency (VF), word list memory (WLM, immediate recall) tests. All the test scores were not significantly influenced by sex and age. There was no significant effect of education/illiteracy on the CERAD verbal fluency (VF) and Word List Memory (immediate recall) test scores, but a weakly significant (p < 0.05) effect on the CSI “D” COGSCORE performance. These normative data will be useful for clinical interpretations of the three components of the 10/66 Dementia Research Program protocol in illiterate and semi-illiterate Moroccan subjects with cognitive disorders.展开更多

To get more information on cognitive impairment of aphasic patients, this study aimed to develop a new cognitive assessment test battery for aphasic patients, the Non-language-based Cognitive Assessment （NLCA）, and evaluate its utility in Chinese-speaking patients with aphasia. Methods： The NLCA consists of five nonverbal tests, which could assess five nonlinguistic cognitive domains such as visuospatial functions, attention test, memory, reasoning, and executive functions of aphasic patients. All tests are modified from the nonverbal items of the current existed tests with some changes to the characteristics of Chinese culture. The NLCA was tested in 157 participants （including 57 aphasic patients, 50 mild cognitive impairment （MCI） patients, and 50 normal controls）, and was compared with other well-established relative neuropsychological tests on the reliability, validity, and utility. Results： The NLCA was fully applicable in the MCI patients and the normal controls, almost working in the aphasic patients （57/62 patients, 91.9%）. The NLCA scores were 66.70± 6.30, 48.67± 15.04, and 77.58±2.56 for the MCI group, the aphasic group, and the control group, respectively , and a significant difference was found among three groups （F = 118.446, P 〈 0.001）. The Cronbach＇s alpha of the NLCA as an index of internal consistency was 0.805, and the test-retest and interrater reliability was adequate （r=0.977 and r= 0.970, respectively）. The correlations of the cognitive subtests and their validation instruments were between 0.540 and 0.670 （all P 〈 0.05）. Spearman＆#39;s correlation analysis indicated that the coefficient of internal consistency of each subtest itself was higher than other subtests.When choosing the Montreal Cognitive Assessment score of 〈26 as the diagnostic criteria of cognitive impairment, the area under the curve for all participants in the control and MCI groups was 0.942 （95% confidence interval： 0.895–0.989）, and an optimal cutoff point of 75.00 seemed to provide the best balance between sensitivity and specificity. Age （r = -0.406, P 〈 0.001） was the main influence factor for the NLCA. Conclusions： The NLCA could efficiently differentiate the cognitive impairment patients from the normal controls and is a reliable and valid cognitive assessment test battery to specially find nonlinguistic cognitive function for aphasic patients.展开更多
