TL;DR: A headband sensor picked up brief bursts of force inside the head during sleep in all 45 people tested. People with neurodegenerative diseases had fewer bursts per minute than healthy volunteers, in an early, not yet peer-reviewed study. Key Findings A…

TL;DR: People with a common type of heart failure scored lower on thinking tests than healthy people of similar age, and an MRI sign of the brain’s fluid-clearing system was lower on the left side of their brains. Lower values of that sign went with lower thin…

TL;DR: In mice, the bone marrow inside the skull holds small immune hubs that pick up proteins leaking out of the brain and react to them, including proteins from brain tumors. Boosting those hubs with a gel placed under the scalp helped mice with brain tumors…

TL;DR: A 2026 preprint in bioRxiv found that Magnetic Resonance Artificial Intelligence Velocimetry (MR-AIV), a physics-informed AI method for estimating brain fluid transport, produced stable velocity and permeability maps across several modeling stress tests…

TL;DR: A 2026 medRxiv preprint used total-body tau PET in Alzheimer’s disease and found stronger brain-organ network synchrony, a pattern that tracked cognitive impairment through cortical tau burden and MRI markers of glymphatic dysfunction. Key Findings Smal…

TL;DR: A 2026 mouse study in Nature Neuroscience found that abdominal muscle contractions during locomotion drove directed brain motion and helped move interstitial fluid through brain tissue during wakefulness. Key Findings Brain motion was tightly coupled to…

TL;DR: A 2022 study in Nature Communications used non-contrast 3D T2-FLAIR MRI, a scan that suppresses ordinary cerebrospinal-fluid brightness, to map possible brain-border drainage routes toward cervical lymph nodes, but FLAIR brightness alone does not prove…
