BACKGROUND AND PURPOSE: Alzheimer's disease is associated with progressive visuo-
spatial dysfunction. This study used functional MR (fMR) imaging with an eye movement …

The neural basis of visuospatial deficits in Alzheimer's disease is unclear. We wished to
investigate the neural basis of visuospatial perception in patients with Alzheimer's disease …

Alzheimer's disease (AD) is known to cause a variety of disturbances of higher visual
functions that are closely related to the neuropathological changes. Visual association areas …

The goals of this study were to evaluate brain activation in patients with probable
Alzheimer's disease (AD), mild cognitive impairment (MCI), and controls while performing a …

Alzheimer's disease (AD) is characterized by disturbances of visuospatial cognition. Given
that these impairments are closely related to metabolic and neuropathological changes, our …

BACKGROUND AND PURPOSE: We applied functional MR imaging with a learning task in
healthy elderly volunteers and in patients with Alzheimer's disease to study brain activation …

Alzheimer's disease is the most common cause of dementia in older adults. Although the
cognitive deficits and pathologic hallmarks of Alzheimer's disease have been well …

Eighteen patients with Alzheimer's disease were studied with positron emission tomographic
measurements of regional cerebral metabolism of glucose. All patients were initially …

Objectives: Parietal lobe dysfunction is an important characteristic of early Alzheimer
disease (AD). Functional studies have shown conflicting parietal activation patterns …

Motion artifacts are a well-known and frequent limitation during neuroimaging workup of
cognitive decline. While head motion typically deteriorates image quality, we test the …
