Oct. 15, 2024 — Alzheimer's disease may damage the brain in two distinct phases, based on new research using sophisticated brain mapping tools. According to researchers who discovered this new ...

A new study reveals that not getting enough of specific stages in the sleep cycle may be linked to cognitive decline and ...

To understand why certain parts of the brain are more affected by Alzheimer's disease, researchers focused on tau, a protein that accumulates in brain cells and disrupt normal activity.

New research reveals that lower proportions of specific sleep stages are associated with reduced brain volume in regions vulnerable to the development of Alzheimer's disease over time.

“Using mathematical and computational models, we found that certain cells in the hippocampus, a brain area important for memory and navigation, are more vulnerable to tau buildup,” said author ...
