The effect of cognitive intervention on brain metabolism in AD is largely unexplored. Therefore, we aimed to investigate cognitive parameters and 18FDG PET to test for effects of a cognitive intervention in patients with aMCI or mild AD. Patients with aMCI (N = 24) or mild AD (N = 15) were randomly assigned either to […]

A group reminiscence approach (GRA) with reality orientation (RO) is widely used as a psychosocial intervention for dementia. Since clinical effectiveness was reported for the intervention, interest has been directed toward areas of the neuronal network that might be being stimulated. We hypothesized that the frontal lobe associated with social interaction was being stimulated. To […]
Effects of memantine on clinical ratings, fluorodeoxyglucose positron emission tomography measurements, and cerebrospinal fluid assays in patients with moderate to severe Alzheimer dementia: a 24-week, randomized, clinical trial

Most experts consider that memantine has a symptomatic treatment, but clinical trials have not yet provided compelling evidence to support a disease-modifying effect. We investigate the effects of memantine on clinical ratings; fluorodeoxyglucose positron emission tomography (FDG-PET) measurements, which can monitor disease-modifying effect; and cerebrospinal fluid (CSF) assays in patients with moderate to severe probable […]
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 […]
Riluzole protects Huntington disease patients from brain glucose hypometabolism and grey matter volume loss and increases production of neurotrophins

Purpose: Huntington disease (HD) mutation increases gain-of-toxic functions contributing to glutamate-mediated excitotoxicity. Riluzole interferes with glutamatergic neurotransmission, thereby reducing excitotoxicity, enhancing neurite formation in damaged motoneurons and increasing serum concentrations of BDNF, a brain cortex neurotrophin protecting striatal neurons from degeneration.; Methods: We investigated metabolic and volumetric differences in distinct brain areas between 11 riluzole-treated […]
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 […]

Introduction: Various biomarkers have been reported in recent literature regarding imaging abnormalities in different types of dementia. These biomarkers have helped to significantly improve early detection and also differentiation of various dementia syndromes. In this study, we systematically applied whole-brain and region-of-interest (ROI) based support vector machine classification separately and on combined information from different […]
