We determined predictors of conversion to Alzheimer's disease (AD) from mild cognitive impairment (MCI) with automated magnetic resonance imaging (MRI) regional cortical volume and thickness measures. One hundred amnestic MCI subjects, 118 AD patients, and 94 age-matched healthy controls were selected from AddNeuroMed study. Twenty-four regional cortical(More)
We have used multivariate data analysis, more specifically orthogonal partial least squares to latent structures (OPLS) analysis, to discriminate between Alzheimer's disease (AD), mild cognitive impairment (MCI) and elderly control subjects combining both regional and global magnetic resonance imaging (MRI) volumetric measures. In this study, 117 AD(More)
To study the ability of neuropsychological tests, manual MRI hippocampal volume measures, regional volume and cortical thickness measures to identify subjects with Alzheimer's disease (AD), mild cognitive impairment (MCI), and healthy age-matched controls. Neuropsychological tests, manual hippocampal volume, automated regional volume and regional cortical(More)
The apolipoprotein E (APOE) ε4 allele is a risk factor for Alzheimer's disease (AD), but its effect on brain volumes is controversial. We explored the effect of the ε4 allele on regional cortical thickness and volume measurements using an automated pipeline in 111 subjects with mild cognitive impairment (MCI), 115 AD patients, and 107 age-matched healthy(More)
BACKGROUND The protective effect of the apolipoprotein E (APOE) ε2 allele against Alzheimer's disease (AD) is controversial. OBJECTIVE Our purpose was to clarify if the ε2 allele affects regional cortical thicknesses and volumes. METHODS Regional cortical thicknesses and volumes were measured with an automated pipeline in 109 subjects with mild(More)
The Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery (CERAD-NB) is a widely used tool in screening for Alzheimer's disease (AD), however, it does not include a validated total score for delayed memory. Our aim was to develop clinically applicable memory compound scores for CERAD-NB and examine whether they and global(More)
Unilateral neglect is a debilitating attentional disorder whereby patients fail to report, respond or orient to information presented on one side of space. Previous studies have demonstrated improvements in neglect symptoms using rehabilitation techniques, such as anchoring or limb activation. We investigated the effectiveness of five interventions in(More)
