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)
Immediate early genes are induced by transient global ischemia. Using immunohistochemistry we studied the effect of intraischemic hypothermia (30 degrees C) on the expression of c-fos and fos-B proteins following 10 min forebrain ischemia in the gerbil. Postischemia (PI) periods of 1 hour (h), 6 h, 1 day (d) and 2 d and nonischemic controls were examined in(More)
BACKGROUND/AIMS Mild cognitive impairment (MCI) is associated with an increased risk of Alzheimer's disease (AD). It would be advantageous to be able to distinguish the characteristics of those MCI patients with a high probability to progress to AD if one wishes to monitor the disease development and treatment. METHODS We assessed the baseline MRI and(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)
Here we describe the AddNeuroMed multicenter magnetic resonance imaging (MRI) study for longitudinal assessment in Alzheimer's disease (AD). The study is similar to a faux clinical trial and has been established to assess longitudinal MRI changes in AD, mild cognitive impairment (MCI), and healthy control subjects using an image acquisition protocol(More)
OBJECTIVE To describe the AddNeuroMed imaging framework for multi-centre magnetic resonance imaging (MRI) assessment of longitudinal changes in Alzheimer's disease and report on early results from the first 24 months of the project. METHODS A multi-centre study similarly to a faux clinical trial has been established to assess longitudinal MRI changes in(More)
Intra-ischemic hypothermia is known to protect neurons against ischemic injury. Microglial cells have been shown to become activated following ischemia and are speculated to play significant roles in the evolution of ischemic neuronal injury. In this study, we examined the effect of intra-ischemic hypothermia on the microglial reaction in the hippocampus(More)
Very preterm birth (gestational age <33 weeks) is associated with alterations in cortical thickness and with neuropsychological/behavioural impairments. Here we studied cortical thickness in very preterm born individuals and controls in mid-adolescence (mean age 15 years) and beginning of adulthood (mean age 20 years), as well as longitudinal changes(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)
