54/100

59/100
A new diagnostic indicator of FDG PET scan abnormality, based on age-adjusted t statistics and an automated voxel-based procedure, is presented and validated in a large data set comprising 110 normal controls and 395 patients with probable Alzheimer's disease (AD) that were studied in eight participating centers.

The visual association test (VAT) is a brief learning task based on imagery mnemonics.

The development of interventions designed to delay the onset of dementia highlights the need to determine the neuropathologic characteristics of individuals whose cognitive function ranges from intact to demented, including those with mild cognitive impairments.

58/100
Individuals with an isolated pathologic diagnosis of AD, hippocampal sclerosis, frontotemporal degeneration, and neurofibrillary tangle--only degeneration usually had substantial hippocampal atrophy, while those with changes of typical aging did not.

This study performed an anatomical parcellation of the MNI spatially normalized single-subject high-resolution T1 volume by delineating main sulci as landmarks to define 45 anatomical volumes of interest (AVOI) in each hemisphere.
-
To evaluate whether magnetic resonance imaging (MRI) of white matter changes in Alzheimer's disease either under- or overestimates the findings on neuropathology.

-
46/100
The prefrontal cortex (PFC) is a heterogeneous cortical structure that supports higher cognitive functions, including working memory and verbal abilities.
-
Cross-sectional positron emission tomography (PET) studies find that cognitively normal carriers of the apolipoprotein E (APOE) epsilon4 allele, a common Alzheimer's susceptibility gene, have abnormally low measurements of the cerebral metabolic rate for glucose (CMRgl) in the same regions as patients with Alzheimer's dementia.
-
62/100
We report the first detailed population-based maps of cortical gray matter loss in Alzheimer's disease (AD), revealing prominent features of early structural change.
-
It has been shown that atrophy of medial temporal lobe structures such as the hippocampus and entorhinal cortex shown on MRI may distinguish patients with Alzheimer's disease from healthy controls.
-
56/100
These findings suggest that the initial 1H MRS change in the pathologic progression of AD is an increase in MI/Cr.
-
36/100
Using quantitative structural MRI protocols, we examined the effects of age on alterations in entorhinal cortex (EC) volume.
-
We used magnetic resonance imaging (MRI) measurements to determine whether persons in the prodromal phase of Alzheimer's disease (AD) could be accurately identified before they developed clinically diagnosed dementia.
-
Functional MRI has recently been used to examine activation associated with aging and dementia, yet little is known regarding the effect of cerebral atrophy on fMRI signal.

Registration of serial MRI volume images provides a powerful method of quantification of brain atrophy that can be used to monitor progression of AD in clinical trials.
-
The cortical anatomy of 6 patients with semantic dementia (the temporal lobe variant of frontotemporal dementia) was contrasted with that of a group of age-matched normal subjects by using voxel-based morphometry, a technique that identifies changes in gray matter volume on a voxel-by-voxel basis.
-
The emergence of drugs that may slow progression of Alzheimer disease, if administered early during its course, has necessitated early diagnosis of the disease itself.
-
In common with Alzheimer's disease and vascular dementia, PVHs and WMHs were significantly more extensive in dementia with Lewy bodies than in controls.

Manganese-superoxide dismutase (Mn-SOD) was localized in the cerebral cortex and hippocampus of patients with Alzheimer-type senile dementia (ATD) by immunocytochemistry and the relationship of Mn-SOD with two major pathological features of ATD, i.e., senile plaques and neurofibrillar tangles (NFTs), was examined.
