Treatment effects of therapeutic cholinesterase inhibitors on visuospatial processing in Alzheimer’s disease: A longitudinal functional MRI study

Background/Aims: Visuospatial impairments are known to occur in Alzheimer’s disease (AD). We hypothesised that functional magnetic resonance imaging (fMRI) response in task-related brain regions would be impaired in patients with AD during the task and that treatment with acetyl cholinesterase inhibitors would enhance activations in brain regions concerned with this visual perceptual processing. Method: Ten […]

Improved visual hallucination by donepezil and occipital glucose metabolism in dementia with Lewy bodies: the Osaki-Tajiri project

Deficits in the cholinergic system are pronounced in dementia with Lewy bodies (DLB) and are more severe in patients with visual hallucinations (VHs). The aim is to identify the occipital glucose metabolism patterns by positron emission tomography (PET) and the changes following donepezil treatment. 13 DLB patients with VHs were enrolled in the study. After […]

Visual evoked potentials to pattern, motion and cognitive stimuli in Alzheimer’s disease

The aim of our study was to verify reported visual dysfunctions of patients with Alzheimer disease with the use of several variants of VEPs and visual ERPs and to learn whether these methods can be useful in diagnostics of AD. We tested 15 patients (6 women and 9 men, aged from 58 to 87) with […]

A randomized controlled trial of cognitive training using a visual speed of processing intervention in middle aged and older adults

Background: Age-related cognitive decline is common and may lead to substantial difficulties and disabilities in everyday life. We hypothesized that 10 hours of visual speed of processing training would prevent age-related declines and potentially improve cognitive processing speed.; Methods: Within two age bands (50-64 and ≥ 65) 681 patients were randomized to (a) three computerized […]
