No CommentsPrediction of survival in alzheimer’s disease – the laser-ad longitudinal study
Alzheimer's disease (AD) is associated with variable but shortened life expectancy. Knowing expected survival time may empower people with AD and their families, but clinicians currently have limited predictive information. Our objective was to identify determinants of survival in a cohort of people with mild to moderate AD and test these on a separate validation...

No CommentsNo association between calhm1 and risk for alzheimer dementia in a belgian population
A non-synonymous polymorphism, rs2986017 (p.P86L), in the newly characterized calcium homeostasis modulator 1 (CALHM1) gene located in the Alzheimer dementia (AD) linkage region on 10q24.33, was reported to increase risk of AD, and affect calcium homeostasis and amyloid [beta] accumulation. We aimed to investigate the association between this functional polymorphism and AD in an independent...

No CommentsNo association between calhm1 variation and risk of alzheimer disease
We examined this variant (rs2986017) in 945 Caucasian Americans with late-onset Alzheimer disease and 875 age-matched Caucasian American controls. No association with risk of late-onset Alzheimer disease (p=0.368 for genotypes; p=0.796 for alleles) was observed in our sample. However, a potential modest association of minor allele homozygosity (TT) with an earlier age-at-onset was seen (p=0.034)....

No CommentsAlzheimer’s dementia by circulation disorders: when trees hide the forest
Authors: Carlos G. Dotti & Bart De Strooper Deposition of amyloid β-peptide in cerebral vessel walls, termed cerebral amyloid angiopathy (CAA), enhances the cognitive deficits associated with Alzheimer's disease. The molecular details by which circulatory defects with hypoxia alter peptide clearance, contributing to brain deposition and AD, are beginning to be elucidated. (Source: Nature Cell...
