Highest usefulness score first. Studies without a score come last.
-
Subclinical cognitive impairment was found to not constitute a unitary phenomenon and heterogeneous subgroups could be differentiated.
-
The authors have devised, implemented, and tested a fast, spatially accurate technique for calculating the high-dimensional deformation field relating the brain anatomies of an arbitrary pair of subjects.

Fourteen inpatients with dementia showing sleep and behavior disorders (average age = 75 years), and 10 control elderly people (average age = 75 years) were carefully observed for 2 months.
-
A simple, completely objective scoring system for a clock completion test has been developed which involves only the number of digits placed in the fourth quadrant of a pre-drawn circle.
-
Since Kraepelin's first description of dementia praecox in 1889 many data and theories have been published on the onset and course of schizophrenia.
-
The present study was designed to determine which of the memory tasks included in the CERAD (Consortium to Establish a Registry for Alzheimer's Disease) neuropsychological battery best differentiate patients with early Alzheimer's disease from cognitively normal elderly control subjects and also best distinguish between the various levels of severity of the dementia process.
-
The suprachiasmatic nucleus, considered to be the endogenous circadian clock in the mammalian brain, shows morphological changes with aging, which become even more pronounced in Alzheimer's disease (AD).
-
Thirty-eight patients with dementia of various etiologies were studied longitudinally to determine the change in cognition over time in subjects with and without hearing impairment.
-
Recent studies of Alzheimer's disease patients have demonstrated (a) marked structural and biochemical alterations in brain regions associated with olfactory function (including the olfactory bulb and entorhinal cortex) and (b) decrements in the ability to identify odorants.
-
A quantitative morphometric analysis was used to estimate neurone and synapse densities in cerebral cortical biopsy tissues from patients with dementia under 65 years of age and pathologically verified as suffering from Alzheimer's disease.
-
Subcortical dementia is a clinical syndrome characterized by slowness of mental processing, forgetfulness, impaired cognition, apathy, and depression.
-
A group of 18 long‐stay patients with a diagnosis of schizophrenia were compared with a group of 10 age‐matched subjects who had been institutionalized by reason of physical disease, on performance on tests of intellectual function; and with a group of agematched healthy subjects, both on tests of intellectual function, and radiographically, using the technique of computerized axial tomography (EMI scan) of the brain.
-
Progressive supranuclear palsy (Steele et al.) has a characteristic pattern of dementia: (1) forgetfulness, (2) slowing of thought processes, (3) emotional or personality changes (apathy or depression with occasional outbursts of irritability), and (4) impaired ability to manipulate acquired knowledge.

CONSIDERABLE interest has been focused on the entity of progressive external ophthalmoplegia (PEO) since the report of Kiloh and Nevin in 1951.1These authors were primarily concerned with the pathogenesis of the ocular muscle weakness, concluding that it was virtually always the result of a myopathic process.

The relation between bilingualism and cognition is informative about the connection between language and mind.
-
Spontaneous, conversational speech in probable dementia of Alzheimer type (DAT) participants and healthy older controls was analysed using eight linguistic measures.
-
Because the field of bilingualism is still relatively new, studies in the linguistics, psycholinguistics, language development and neurolinguistics of bilingualism have often produced conflicting results.
-
The Indo‐US Cross‐National Dementia Epidemiology Study seeks to compare two rural populations, in the US and India: the Monongahela Valley, a rural community of relatively low socioeconomic status in southwestern Pennsylvania (USA), and Ballabgarh, a rural community near New Delhi in North India.
-
The authors summarize developments in the concept of working memory as a multicomponent system, beginning by contrasting this approach with alternative uses of the term working memory.
-
Among 10,489 participants with incident MCI, the mean age at the incident MCI wave was 70.6 years (SD = 11.53), and 56.6% were female.
-
RNT was associated with increasing global amyloid accumulation even after controlling for psychological symptoms (B = 0.0120, 95% Confidence Interval 0.003 to 0.021, P = 0.012), and in sensitivity analyses limited to participants aged ≥50 or ≥60.
-
Under nested cross-validation, the WWL kernel achieves a balanced accuracy of $0.651\pm0.028$, significantly outperforming both a raw-feature SVM and a histogram-based WL-kernel baseline.
-
Most evidence on dementia risk factors comes from older or clinical samples, leaving their relation to normal cognitive aging unclear.
-
Precision medicine approaches require physiological effects to be informative when translated to the individual.
-
Higher educational attainment is associated with steeper measured cognitive decline among older adults in India, but whether this association is uniform across the country is unknown.
