The maintenance of the effects of Cerebrolysin, a peptidergic compound with neurotrophic activity, on cognitive performance and qEEG activity was investigated through a 12-week, open-label extension of a 4-week, randomised, placebo-controlled pilot study. Thirty-three out of 41 patients with mild-to-moderate severe probable vascular dementia (VaD) according to NINDS-AIREN participating in the double-blind phase of the […]

Objective: Non-steroidal anti-inflammatory drugs such as ibuprofen have a protective role on risk of Alzheimer’s disease (AD). Here we evaluated the hypothesis that long-term ibuprofen treatment affects cortical sources of resting electroencephalographic (EEG) rhythms in mild AD patients.; Methods: Twenty-three AD patients (13 treated AD IBUPROFEN; 10 untreated AD PLACEBO) were enrolled. Resting EEG data […]
A phase I trial of deep brain stimulation of memory circuits in Alzheimer’s disease

Objective: Alzheimer disease (AD) is characterized by functional impairment in the neural elements and circuits underlying cognitive and memory functions. We hypothesized that fornix/hypothalamus deep brain stimulation (DBS) could modulate neurophysiological activity in these pathological circuits and possibly produce clinical benefits.; Methods: We conducted a phase I trial in 6 patients with mild AD receiving […]
Voxel-based morphometry in individual patients: a pilot study in early Huntington disease

Ilg, R.
Background and Purpose: Voxel-based morphometry (VBM) has proved a powerful method to detect subtle changes of gray matter (GM) at the group level but the role of VBM for the detection of GM changes in single subjects, especially in those with suspected neurodegenerative disorder, remains uncertain. Here, we performed single subject analyses in 22 patients […]
Decreased activation along the dorsal visual pathway after a 3-month treatment with galantamine in mild Alzheimer disease: a functional magnetic resonance imaging study

Visual perception has been shown to be altered in Alzheimer disease (AD) patients, and it is associated with decreased cognitive function. Galantamine is an active cholinergic agent, which has been shown to lead to improved cognition in mild to moderate AD patients. This study examined brain activation in a group of mild AD patients after […]
Differential effects of global and cerebellar normalization on detection and differentiation of dementia in FDG-PET studies

FDG-PET ([18F]fluorodeoxyglucose positron emission tomography) is frequently used to improve the differential diagnosis of dementia. However, a fundamental methodological issue of the reference area for the intensity normalization procedure is still unsolved. Here, we systematically compared the two most commonly used normalization methods to the cerebral and to the cerebellar metabolic rate for glucose with […]

Diffusion tensor imaging (DTI) detects white matter damage in neuro-psychiatric disorders, but data on reliability of DTI measures across more than two scanners are still missing. In this study we assessed multicenter reproducibility of DTI acquisitions based on a physical phantom as well as brain scans across 16 scanners. In addition, we performed DTI scans […]
Accelerated cognitive decline in patients with type 2 diabetes: MRI correlates and risk factors

Background: Type 2 diabetes mellitus is associated with an increased risk of cognitive decline and dementia. We examined brain imaging correlates and vascular and metabolic risk factors of accelerated cognitive decline in patients with type 2 diabetes.; Methods: Cognitive functioning and brain volume as well as metabolic and vascular risk factors were assessed twice in […]

Treatment of Alzheimer’s disease (AD) with acetylcholinesterase inhibitors (AChEI) enhances cholinergic activity and alleviates clinical symptoms. In the present functional magnetic resonance imaging (fMRI) study, we investigated the effect of the AChEI rivastigmine on cognitive function and brain activation patterns during a face recognition memory task. Twenty patients with newly-diagnosed mild AD were administered a […]
