## Executive Summary
New research links long sleep hours to elevated levels of a blood protein associated with Alzheimer's disease.

## Intelligence Brief
A study from UT Health San Antonio has identified a connection between sleeping for long hours and higher levels of an Alzheimer's-related protein in the blood. Additional research suggests that sleep disorders can change the brain and alter communication networks across the adult lifespan.


Coverage from Medical Xpress, SciTechDaily, and Neuroscience News emphasizes the link between sleep, genes, and Alzheimer's. ThePrint reports that poor sleep affects brains differently, with a specific note on the impact on older women.


Future developments depend on the ongoing study of how poor sleep alters brain communication and the role of genetics in these Alzheimer's-related protein levels.
