Microstructural white matter changes are present in cognitively normal individuals in the pre-aMCI stage, and may serve as a potential imaging marker of early AD-related brain changes.
-
This study aimed to determine the stratified normative data by age and education for a modified version of the Mini-Mental State Examination (MMSE) test from a large sample of community-dwelling Chinese older adults in Singapore, and to examine the MMSE's value in detecting early cognitive impairment.

Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery.
-
The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment, having surpassed the well-known limitations of the MMSE.

48/100
In individuals without a prior diagnosis of cognitive impairment, the prevalence of dementia was low, but the prevalence of CIND was high.

Most cross-sectional and longitudinal studies suggest an association between cognitive impairment and CKD.
-
58/100
Accurate prediction of clinical changes of mild cognitive impairment (MCI) patients, including both qualitative change (i.e., conversion to Alzheimer's disease (AD)) and quantitative change (i.e., cognitive scores) at future time points, is important for early diagnosis of AD and for monitoring the disease progression.
-
A careful clinical evaluation of sleep disorders should be performed routinely in the clinical setting of persons with cognitive decline.
-
46/100
With the suggested adaptations, the CDN is expected to be a useful tool for supporting community-dwelling persons with mild dementia and their carers.
-
An algorithm-derived diagnosis of aMCI showed few sociodemographic associations but was consistently associated with higher disability and neuropsychiatric symptoms in addition to showing substantial variation in prevalence across LAMIC populations.
-
Third, we benchmarked the results of our virtual reality episodic memory test against a classical memory test and a subjective daily memory complaint scale.
-
Prevalence and incidence estimates associated with MCI vary greatly both between definitions and within a definition across the 42 publications.
-
Whether mild cognitive impairment (MCI) has a distinct neuropathological profile that reflects an intermediate state between no cognitive impairment and dementia is not clear.
-
The Montreal Cognitive Assessment (MoCA) has been proved brief and sensitive to screen for mild cognitive impairment (MCI) and early dementia in some developed countries or areas.
-
The relation between pathology and cognitive dysfunction in dementia is still poorly understood, although disturbed communication between different brain regions is almost certainly involved.
-
This study aimed to examine the validity and item-response characteristics of the Mini-Mental State Examination (MMSE), which is used for assessing cognitive function, in Japanese older adults.
-
Modifiable risk factors for MCI should be sought (at the very latest) in persons who already have MCI, as their optimal treatment may improve these patients' cognitive performance or keep the existing deficits from progressing.
-
45/100
This aim of this study was to assess the clinical utility of the Montreal Cognitive Assessment (MoCA) as a screening instrument for cognitive impairment in patients referred to a memory clinic, alone and in combination with the Mini-Mental State Examination (MMSE).
-
Acute cognitive impairment and delirium occur after major stroke and are associated with poor cognitive outcome.
-
Cognitive assessment appropriate for diagnosis of dementia and CIND in large population surveys could be improved with more targeted information from informants and additional cognitive tests targeting other areas of brain function.
-
Our results suggest that diet may be a powerful environmental factor that modulates Alzheimer disease risk through its effects on central nervous system concentrations of Aβ42, lipoproteins, oxidative stress, and insulin.
-
As ascertained by several operational definitions, MCI is a heterogeneous entity at the population level but progresses to dementia at rates higher than in normal elderly individuals.
-
48/100
Dementia and delirium were prevalent, yet under-recognized, in acute medical geriatric inpatients.
-
This relationship was evident even after accounting for degree of memory deficit across the continuum of cognitive impairment and dementia.
-
61/100
The TICS has high diagnostic validity for identification of dementia among ethnically diverse older adults, especially when supported by the DQ and prior visit data.
-
The National Institute on Aging and the Alzheimer's Association charged a workgroup with the task of developing criteria for the symptomatic predementia phase of Alzheimer's disease (AD), referred to in this article as mild cognitive impairment due to AD.
-
MCI represents a prodromal stage of AD, and inflammation occurs as one of the earliest pathological events in AD.
-
Cognitive dysfunction, including dementia and delirium, is prevalent in geriatric emergency department (ED) patients, but often remains undetected.
-
Dementia due to Alzheimer disease is preceded by about 5 to 6 years of accelerated decline in multiple cognitive functions.
-
The results indicate that a-MCI and na-MCI display a stable pattern of deficits to attention, working memory, and executive function.
-
Complaints of poor memory by older people, particularly when new, may be a realistic subjective appraisal of recent brain changes independent of observed cognitive decline.
-
135 subjects enrolled in a longitudinal clinicopathologic study were administered the MoCA by a single physician and the MMSE by a trained research assistant.
-
GOF indices were highest in normal controls, intermediate in MCI, and lowest in AD (p Conclusions fMRI connectivity indices distinguish patients with MCI who undergo cognitive decline and conversion to AD from those who remain stable over a 2- to 3-year follow-up period.
-

We investigated the prevalence of dementia and mild cognitive impairment (MCI) and the factors associate with risk of dementia from a representative nationwide sample of Korean elders. 8,199 randomly-sampled Koreans aged 65 years or older were invited to participate in the Phase I screening assessment using Mini-Mental State Examination by door-to-door home visit, and 6,141 subjects (response rate = 74.9%) responded.
-
Total tau (T-tau), tau phosphorylated at threonine 181, and β-amyloid 1-42 peptide (Aβ42) were immunoassayed in CSF samples obtained from patients with MCI enrolled in the Alzheimer's Disease Neuroimaging Initiative.

Alzheimer's disease (AD) is a slowly progressing form of dementia characterized in its earliest stages as a loss of memory.

The authors' findings suggest that the effectiveness of explicit-memory training in patients with MCI is associated with training-specific increases in activation and connectivity in a distributed neural system that includes areas involved in explicit memory.
-
Mild cognitive impairment (MCI) is a syndrome thought to be a prodrome of dementia for some patients.
-
The presence of Met-BDNF allele, particularly in association with APOE*E4, may predict a worse cognitive outcome in patients with MCI.

Among 1,969 subjects without dementia, 329 subjects had MCI, with a prevalence of 16.0% (95% confidence interval [CI] 14.4-17.5) for any MCI, 11.1% (95% CI 9.8-12.3) for amnestic MCI, and 4.9% (95% CI 4.0-5.8) for nonamnestic MCI.

The concept of cognitive insight was introduced in 2004 to describe the capacity of patients with psychosis to distance themselves from their psychotic experiences, reflect on them, and respond to corrective feedback.
-
MCI diagnosis frequencies are substantively affected by the stringency of the criteria, but the relative rankings of MCI subtype diagnoses are fairly consistent regardless of the stringency of the criteria.
