Alzheimer Signs Before Memory Loss
Early brain changes may signal Alzheimer's years before symptoms.
In brief
Early brain changes may signal Alzheimer's years before symptoms. Beta-amyloid levels predict brain shrinkage years before dementia symptoms. Originally reported by Psychologies.
Early Alzheimer Signs
Scientists found brain changes years before memory loss.
“Beta-amyloid protein accumulates years before dementia symptoms”
Beta-Amyloid Protein
This protein forms plaques in brain tissue.
“Beta-amyloid protein deposits around neurons”
Brain Imaging Study
1,329 people over 50 years old were scanned.
“Researchers followed 1,329 people without dementia”
Brain Shrinkage
Brain regions shrink years before dementia symptoms.
“Brain shrinkage appears in temporal and parietal regions”
Beta-Amyloid Predicts Shrinkage
Higher beta-amyloid levels mean faster brain shrinkage.
“More beta-amyloid predicts brain atrophy in key regions”
Gender and Genetics
Women and APOE-epsilon4 carriers show faster shrinkage.
“Shrinkage is more severe in women and APOE-epsilon4 carriers”
Here's the gist
Beta-amyloid levels predict brain shrinkage years before dementia symptoms.
