Brain shape changes linked to cognitive decline
New research links changes in brain shape to cognitive decline, offering insights into early dementia detection.
Why it matters
- Understanding dementia risk can improve care and treatments.
- Early detection is crucial for managing neurodegenerative diseases.
By the numbers
- Study analyzed 2,603 MRI brain scans.
- Participants aged 30 to 97.
The big picture
- Brain shape changes unevenly with age, linked to cognitive decline.
- Pressure on the entorhinal cortex may explain Alzheimer's pathology.
What they're saying
- Researchers suggest this could be a new way to think about Alzheimer's mechanisms and early detection.
Caveats
- More data needed to establish precise relationships.
What’s next
- Team plans to explore why some brain areas expand with age and its relation to cognition.
