MONDAY, Oct. 27, 2025 (HealthDay News) — Faulty waste clearance in the brain could be contributing to dementia, a new study says.

Impaired movement of cerebrospinal fluid — the clear liquid that cushions and cleans the brain — predicted people’s risk of dementia later in life, researchers reported Oct. 23 in the journal Alzheimer’s & Dementia .
