Treatment strategies for patients with depression and cognitive impairment (DEP-CI), who are at high risk to develop a clinical diagnosis of dementia, are not established. This issue is addressed in the donepezil treatment of cognitive impairment and depression (DOTCODE) pilot clinical trial. The DOTCODE study is the first long-term treatment trial that assesses differences in […]
Early detection of patients in the pre demented stage of Alzheimer’s disease: the Pre-Al Study
Mahieux, F.,
Onen, F.,
Berr, C.,
Volteau, M.,
Habert, M. O.,
Legrain, S.,
Dubois, B.
Objectives: The aim of the Pre-Al study is to evaluate and compare the predictive value of different tools for an early identification of Alzheimer’s disease.; Design and Participants: Patients coming for consultation to memory clinics without dementia were included if they had an objective memory or attention trouble assessed by a MMSE score > 25 […]
MRI signatures of brain macrostructural atrophy and microstructural degradation in frontotemporal lobar degeneration subtypes

Brain magnetic resonance imaging (MRI) studies have demonstrated regional patterns of brain macrostructural atrophy and white matter microstructural alterations separately in the three major subtypes of frontotemporal lobar degeneration (FTLD), which includes behavioral variant frontotemporal dementia (bvFTD), semantic dementia (SD), and progressive nonfluent aphasia (PNFA). This study was to investigate to what extent the pattern […]

Several molecular subtypes of sporadic Creutzfeldt-Jakob disease have been identified and electroencephalogram and cerebrospinal fluid biomarkers have been reported to support clinical diagnosis but with variable utility according to subtype. In recent years, a series of publications have demonstrated a potentially important role for magnetic resonance imaging in the pre-mortem diagnosis of sporadic Creutzfeldt-Jakob disease. […]
Cognitive function and brain structure in persons with type 2 diabetes mellitus after intensive lowering of blood pressure and lipid levels: a randomized clinical trial

Miller, Michael E.
Importance: Persons with type 2 diabetes mellitus (T2DM) are at increased risk for decline in cognitive function, reduced brain volume, and increased white matter lesions in the brain. Poor control of blood pressure (BP) and lipid levels are risk factors for T2DM-related cognitive decline, but the effect of intensive treatment on brain function and structure […]
Cognitive rehabilitation changes memory-related brain activity in people with Alzheimer disease

Clare, L.,
Yuen, K. S. L.,
Woods, R. T.,
Evans, S. J.,
Parkinson, C. H.,
Rugg, M. D.,
Linden, D. E. J.
Background: People with Alzheimer disease (AD) are capable of new learning when cognitive support is provided, suggesting that there is plasticity even in a degenerating brain. However, it is unclear how a cognition-focused intervention operates on a neural level.; Objective: The present study examined the effects of cognitive rehabilitation (CR) on memory-related brain activation in […]
Magnetization transfer imaging in premanifest and manifest huntington disease: a 2-year follow-up

Background and Purpose: MTI is a quantitative MR imaging technique that has recently demonstrated structural integrity differences between controls and patients with HD. Potentially, MTI can be used as a biomarker for monitoring disease progression. To establish the value of MTI as a biomarker, we aimed to examine the change in these measures during the […]
Study of the voxel-based specific regional analysis system for Alzheimer’s disease imaging sequence after magnetic resonance apparatus replacement

In our institute, an MR apparatus, MAGNETOM VISION (Siemens) was replaced by ECHELON Vega (HITACHI). Z-score data acquired by MPRAGE (VISION) was compared with those by radio frequency-spoiled steady-state acquisition with rewinded gradient echo (RSSG) and gradient echo inversion recovery (GEIR) (ECHELON). For this study, ten normal volunteers were recruited and their data ware obtained […]

Background: To examine the effect of multicomponent exercise program on memory function in older adults with mild cognitive impairment (MCI), and identify biomarkers associated with improvement of cognitive functions.; Methodology/principal Findings: Subjects were 100 older adults (mean age, 75 years) with MCI. The subjects were classified to an amnestic MCI group (n = 50) with neuroimaging measures, […]
