Biomarkers have gained an increased importance in the past years in helping physicians to diagnose Alzheimer’s disease (AD). This study was designed to identify a blood-based, transcriptomic signature that can differentiate AD patients from control subjects. The performance of the signature was then evaluated for robustness in an independent blinded sample population. RNA was extracted […]
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 […]
Visual perception has been shown to be altered in Alzheimer disease (AD) patients, and it is associated with decreased cognitive function. Galantamine is an active cholinergic agent, which has been shown to lead to improved cognition in mild to moderate AD patients. This study examined brain activation in a group of mild AD patients after […]
Objective: Lithium, a first-line drug for the treatment of bipolar depression, has recently been shown to regulate glycogen synthase kinase-3 (GSK-3), a kinase that is involved in the phosphorylation of the tau protein. Since hyperphosphorylation of tau is a core pathological feature in Alzheimer’s disease, lithium-induced inhibition of GSK-3 activity may have therapeutic effects in […]
Diffusion tensor imaging (DTI) detects white matter damage in neuro-psychiatric disorders, but data on reliability of DTI measures across more than two scanners are still missing. In this study we assessed multicenter reproducibility of DTI acquisitions based on a physical phantom as well as brain scans across 16 scanners. In addition, we performed DTI scans […]
Background: Alzheimer’s Disease Neuroimaging Initiatives (“ADNI”) aim to validate neuroimaging and biochemical markers of Alzheimer’s disease (AD). Data of the pilot European-ADNI (E-ADNI) biological marker programme of cerebrospinal fluid (CSF) and plasma candidate biomarkers are reported.; Methods: Six academic EADC centres recruited 49 subjects (healthy controls, subjects with mild cognitive impairment (MCI) and AD). We […]
