Brains grow differently in babies with Alzheimer’s gene

A brain imaging study of 162 healthy babies (2-25 months) has found that those who carried the ApoE4

One Alzheimer's risk gene may begin to affect brains from childhood

A gene linked to Alzheimer's has been linked to brain changes in childhood. This gene, SORL1, has two connections to Alzheimer’s: it carries the code for the sortilin-like receptor, which is involved in recycling some molecules before they develop into amyloid-beta

Gene variation associated with brain atrophy in MCI

Loss of smell early sign of Alzheimer’s

Memory complaints linked to higher risk of MCI & dementia

Data from 6257 older adults (aged 55-90) evaluated from 2005-2012 has revealed that concerns about memory should be taken seriously, with subjective complaints associated with a doubled risk of developing mild cognitive impairment

New biomarker shows Alzheimer's disease long before symptoms

Analysis of mitochondrial DNA (mtDNA) in the cerebrospinal fluid has found that both symptomatic Alzheimer’s patients and asymptomatic patients at risk of Alzheimer’s showed a significant decrease in levels of circulating cell-free mtDNA in the CSF.

Brainwaves indicate the presence and severity of Alzheimer's

Comparison of the EEGs of 27 healthy older adults, 27 individuals with mild Alzheimer's and 22 individuals with moderate cases of Alzheimer’s, has found statistically significant differences across the three groups, using an algorithm that dissects brain waves of varying frequencies.

New biomarkers for early Alzheimer's diagnosis

Analysis of 40 spinal marrow samples, 20 of which belonged to Alzheimer’s patients, has identified six proteins in spinal fluid that can be used as markers for Alzheimer's.

Default mode network changes predict Alzheimer’s

Data from 848 adults of all ages has found that brain volume in the default mode network declined in both healthy and pathological aging, but the greatest decline occurred in Alzheimer’s patients and in those who progressed from mild cognitive impairment

Tracking preclinical Alzheimer's progression

New research supports the classification system for preclinical Alzheimer’s proposed two years ago. The classification system divides preclinical Alzheimer's into three stages:
