## Alzheimer’s Risk Gene
1 in 4 Americans carry at least one copy of APOE ε4 gene variant increasing Alzheimer’s risk.
## Study Participants
Murdoch University researchers examined dietary patterns of 185 older adults without dementia.
## Key Finding
Those with APOE ε4 gene variant following Western diet experienced faster decline in attention.
## Researcher Statement
Lead researcher Blagojevic Castro said what we eat may be one part of a much larger picture of healthy brain aging.
