Summary: A new study reveals that poor sleep in older adults disrupts the brain’s glymphatic system, responsible for clearing harmful waste and toxins. Researchers found that compromised sleep quality leads to dysfunction in this crucial system, potentially increasing risks for memory decline and cognitive impairments.

Using advanced brain imaging in 72 older adults, the research highlighted that poor sleep negatively impacts connections within brain networks linked to memory performance. These insights emphasize the importance of maintaining good sleep hygiene to support brain health and healthy aging.
