Summary

In this study, we found that participants with an APOEe4 genotype (a known genetic risk factor for dementia) were more likely to have a smaller hippocampal molecular layer, and this change was apparent at both the baseline and 2-year follow up.

Together with previous findings, it appears that the molecular layer may be one of the first areas to show vulnerability to the pathological hallmarks of Alzheimer’s. However, it was noted that differences in the molecular layer were not significantly related to dementia risk defined by family history or cardiovascular factors.

Association between midlife dementia risk factors and longitudinal brain atrophy: the PREVENT-Dementia study

Individuals with a higher likelihood of developing Alzheimer’s disease dementia in the future, as predicted by their mid-life CAIDE score, show more shrinkage of brain volume, measured over the course of two years.

 

Protocol for a conversation-based analysis study: PREVENT-ED investigates dialogue features that may help predict dementia onset in later life

This publication lays out plans for the PREVENT Elicitation of Dialogues (PREVENT-ED) substudy. This project aims to analyse specific features of speech during conversation with PREVENT participants. The researchers seek to determine if there are any associations between changes in spoken dialogue and other risk factors for Alzheimer’s disease. Ultimately they want to know whether such dialogue analysis could be useful in screening for early stages of disease.
