Deep brain stimulation (DBS) of the subthalamic nucleus (STN) significantly improves quality of life (QoL) in Parkinson’s disease (PD). Dementia is considered as a contraindication for STN-DBS. However, no controlled study assessed the impact of STN-DBS on the QoL and motor outcome in PD patients with a borderline global cognitive impairment. We studied clinical baseline […]
Memantine and brain atrophy in Alzheimer’s disease: a 1-year randomized controlled trial

Scheltens, Philip
The primary objective of this study was to evaluate the rate of total brain atrophy (TBA) with serial magnetic resonance imaging (MRI), using the Brain Boundary Shift Integral (BBSI), in patients with probable Alzheimer’s disease (AD) over the course of 52 weeks of treatment with memantine or placebo. This was a multi-national, randomized, double-blind, placebo-controlled, […]
Effect of acupuncture in mild cognitive impairment and Alzheimer disease: a functional MRI study

We aim to clarify the mechanisms of acupuncture in treating mild cognitive impairment (MCI) and Alzheimer disease (AD) by using functional magnetic resonance imaging (fMRI). Thirty-six right-handed subjects (8 MCI patients, 14 AD patients, and 14 healthy elders) participated in this study. Clinical and neuropsychological examinations were performed on all the subjects. MRI data acquisition […]
Commentary on “A roadmap for the prevention of dementia II. Leon Thal Symposium 2008.” The Multidomain Alzheimer Preventive Trial (MAPT): a new approach to the prevention of Alzheimer’s disease

Touchon, Jacques,
Vellas, B.
Background: Because no effective curative approaches are available, preventive approaches in the field of Alzheimer’s disease (AD) are needed. We present the design of the ongoing Multidomain Alzheimer Preventive Trial (MAPT) Study. Several previous studies suggested that many factors may be involved in the occurrence of AD at late ages. Because of the probable multifactorial […]
Protocol for a randomized controlled trial evaluating the effect of physical activity on delaying the progression of white matter changes on MRI in older adults with memory complaints and mild cognitive impairment: the AIBL Active trial

Background: Older adults free of dementia but with subjective memory complaints (SMC) or mild cognitive impairment (MCI) are considered at increased risk of cognitive decline. Vascular risk factors (VRF), including hypertension, heart disease, smoking, hypercholesterolemia and lack of physical activity (PA) have been identified as modifiable risk factors contributing to cognitive decline, and white matter […]
Acute caffeine administration effect on brain activation patterns in mild cognitive impairment

Previous studies showed that acute caffeine administration enhances task-related brain activation in elderly individuals with preserved cognition. To explore the effects of this widely used agent on cognition and brain activation in early phases of cognitive decline, we performed a double-blinded, placebo-controlled functional magnetic resonance imaging (fMRI) study during an n-back working memory task in […]
Differences in regional brain metabolism associated with specific formulations of hormone therapy in postmenopausal women at risk for AD

Brooks, John,
Rasgon, Natalie L.
Differential cerebral metabolic effects of various hormone therapy formulations, and their associations with cognitive status, remain to be established. The principal aim of the current study was to assess relationships between regional cerebral metabolism and estrogen-based hormone therapies. Postmenopausal women (n=53) at elevated risk for Alzheimer’s disease (AD) were on estrogen-containing hormone therapy for at […]
11C-PiB PET assessment of change in fibrillar amyloid-beta load in patients with Alzheimer’s disease treated with bapineuzumab: a phase 2, double-blind, placebo-controlled, ascending-dose study

Background: Carbon-11-labelled Pittsburgh compound B ((11)C-PiB) PET is a marker of cortical fibrillar amyloid-beta load in vivo. We used (11)C-PiB PET to investigate whether bapineuzumab, a humanised anti-amyloid-beta monoclonal antibody, would reduce cortical fibrillar amyloid-beta load in patients with Alzheimer’s disease.; Methods: Patients with mild-to-moderate Alzheimer’s disease were randomly assigned to receive intravenous bapineuzumab or […]
Effect of memantine on resting state default mode network activity in Alzheimer’s disease

Frisoni, Giovanni B.
Background: Memantine is an approved symptomatic treatment for moderate to severe Alzheimer’s disease that reduces the excitotoxic effects of hyperactive glutamatergic transmission. However, the exact mechanism of the effect of memantine in Alzheimer’s disease patients is poorly understood. Importantly, the default mode network (DMN), which plays a key role in attention, is hypoactive in Alzheimer’s […]

Here we report the first multi-center clinical trial in Alzheimer’s disease (AD) using fluorodeoxyglucose positron emission tomography ([18F]FDG-PET) measures of brain glucose metabolism as the primary outcome. We contrasted effects of 12 months treatment with the PPARγ agonist Rosiglitazone XR versus placebo in 80 mild to moderate AD patients. Secondary objectives included testing for reduction […]
