48/100
Magnetic resonance imaging-based volumetric measurements provide a useful technique for quantifying in vivo regional cerebral atrophy in Alzheimer disease (AD).

Capturing the dynamics of gray matter (GM) atrophy in relation to the conversion from mild cognitive impairment (MCI) to clinically probable Alzheimer's disease (AD) would be of considerable interest.

Despite variation and overlap of atrophy patterns, visual inspection of regional atrophy on MRI may aid in discriminating AD and FTLD.

This potential benefit must be balanced against the possibility that ventricular volumes may be more likely to be affected by factors other than neurodegeneration.

A valid quantitative imaging method for the measurement of amyloid deposition in humans could improve Alzheimer's disease (AD) diagnosis and antiamyloid therapy assessment.
-
In nondemented individuals, entorhinal cortex atrophy is associated with risk of Alzheimer disease.

The demographics of aging suggest a great need for the early diagnosis of dementia and the development of preventive strategies.
-
Formation of senile plaques composed of amyloid beta peptide, a pathological hallmark of Alzheimer disease, in human brains precedes disease onset by many years.
-
Region specific correlations between corpus callosum size and EEG coherence suggest that the decline in interhemispheric connectivity in Alzheimer's disease results from a specific loss of cortical association neurones projecting through the corpus callosum.
-
Increased annual atrophy rate in the medial temporal lobe is a potential diagnostic marker of the progression of Alzheimer disease.
-
Alzheimer's disease is characterized both by a lower mean level of functional connectivity as well as by diminished fluctuations in the level of synchronization.
-
In cross-section and longitudinally, our results show that evaluations of the P-tau231 level are highly correlated with reductions in the MRI hippocampal volume and by using CSF and MRI measures together one improves the separation of NL and MCI.
-
Alzheimer's disease (AD) is the most common form of dementia and is characterised by progressive impairment in cognitive function and behaviour.
-
We developed an anatomical mapping technique to detect hippocampal and ventricular changes in Alzheimer disease (AD).
-
The study aimed at mapping (i) the distributed electroencephalographic (EEG) sources specific for mild Alzheimer's disease (AD) compared to vascular dementia (VaD) or normal elderly people (Nold) and (ii) the distributed EEG sources sensitive to the mild AD at different stages of severity.
-
Neuroimaging studies in healthy subjects have yielded controversial results about the neural substrates of autobiographical memory.
-
Recent functional imaging studies have revealed coactivation in a distributed network of cortical regions that characterizes the resting state, or default mode, of the human brain.
-
