This pilot study aims to explore the psychometric properties of the Cognitive Function Instrument (CFI) as a measure of subjective cognitive complaints (SCC) and its performance in distinguishing mild...
One hundred ninety-four community-dwelling non-demented older adults with racial/ethnic diversity were included. Unidimensionality and internal consistency of the CFI were examined using factor analys...
The CFI demonstrated adequate internal consistency; however, the fit for a unidimensional model was suboptimal. The CFI distinguished MCI from NC alone or in combination with MoCA. ROC analysis showed...
Our findings support the use of CFI as a brief and easy-to-use screen to detect MCI in culturally/linguistically diverse older adults....
What is the key scientific question or problem of central interest of the paper? Subjective cognitive complaints (SCCs) are considered the earliest sign of dementia in older adults. However, it is unc...
Since China adopted a policy to eliminate rural learning centers, boarding has become an important feature of the current rural student community. However, there is a lack of consensus on the impact o...
Using a sample of 5,660 seventh-grade students from 160 rural junior high schools across 19 counties, we identify a causal relationship between boarding and student abilities with the instrumental var...
The results suggest that boarding positively influences memory and attention, while it has no significant effect on other cognitive abilities such as reasoning, transcription speed, and accuracy. Furt...
Given the widespread prevalence of boarding schools in rural regions, our study highlights the growing importance of improving school management to promote the development of students' cognitive abili...
Decreases in cognitive function impair occupational performance, reduce occupational safety, and increase musculoskeletal injury risk. The aim of this paper was to identify measures that may be used t...
A rapid review....
A rapid search of Academic Search Complete, MEDLINE, PsycINFO, and SPORTSDiscus databases was conducted....
original peer reviewed research articles, written in English, published between 2002 and 2022, and using human participants with no health issues in military training environments or active service....
Of the 248 articles screened, 58 full-text articles were assessed for eligibility and 29 included in the review. Of these, 16 papers presented data from multi-stressor military training environments, ...
Prolonged exposure to high-stress military environments compromises multiple aspects of cognitive function. These findings highlight the need for a suite of biomarkers to monitor cognitive function an...
To investigate how conceptualizations of cognition and aging are displayed through evaluations and accounts after cognitive testing with elders who do not have dementia....
14 persons >65 years of age without clinical memory loss were tested with the MMSE and interviewed about their experiences. The audio-recordings were transcribed according to Conversation Analytic con...
The results show how the interviewer and participant being tested evaluate and account for face threats related to the cognitive and communicative competence of the person being tested. Examples of ev...
Inviting participants to share their experiences of cognitive testing can reveal valuable information on how they conceptualize cognition and aging, as well as the testing process itself. Reflections ...
The Cognitive Performance Scale (CPS), a minimum data set instrument of the interRAI, was initially designed to evaluate cognition in residential care and has demonstrated strong diagnostic accuracy. ...
Mixed methods....
The observational study was conducted in rehabilitation wards. Diagnostic accuracy was used to explore the level of agreement between CPS and Montreal Cognitive Assessment (MoCA) in 321 inpatients (62...
The diagnostic accuracy of the CPS was poor when MoCA was less than 24 as a gold standard, with an area under the curve of 0.69 (standard error 0.03, 95% confidence interval = 0.62-0.75). The CPS had ...
Neurotrophins are a family of secreted proteins expressed in the peripheral nervous system and the central nervous system that support neuronal survival, synaptic plasticity, and neurogenesis. Brain-d...
Research combining physical activity with the training of cognitive skills such as executive functions is emerging as a novel and fruitful intervention approach for children....
The prevalence of neurodegenerative disorders, particularly dementia, is on the rise across many countries worldwide. This negative trend calls for improving our understanding of cognitive aging. Whil...
The study aimed to explore longitudinal cognitive outcomes and to ascertain predictors of conversion to dementia in a hospital-based mild cognitive impairment (MCI) cohort classified according to the ...
Subjects aged >55 years who had a clinical diagnosis of MCI at initial visit between 2010 and 2018, with at least one formal neuropsychological assessment at baseline and follow-up of a minimum of ...
Ninety-five patients with MCI met the inclusion criteria with a mean age of 68.4 ± 6.4 years at baseline and a mean duration of follow-up for 6.4 ± 3.2 years. The cumulative conversion rate to dementi...
There was a higher risk of conversion associated with multidomain MCI. Logistic regression-based estimations of dementia risk utilizing domain-based neuropsychology test scores in MCI have high specif...
It is now well recognized that brain damage and/or atrophy apparent on MRI is only moderately correlated to cognitive functioning. The cognitive reserve (CR) hypothesis has been proposed to explain th...
A neuropsychological evaluation was performed on 84 pwMS aged between 27 and 78 years old and the CR Index questionnaire (CRIq) was used to estimate CR. The EDSS scale was used to assess the degree of...
A moderating effect of CR was observed in the relationship between EDSS score and specific cognitive domains: processing efficiency, visuospatial learning and memory, as well as a tendency for verbal ...
The results support the protective role of CR in a sample of pwMS with a wide age range. This role seems to be limited to specific cognitive tasks that pose a greater challenge and therefore require g...
