A new study reveals that fragmented sleep causes cellular damage to the brain's blood vessels, providing further evidence to suggest that sleep disruption predisposes the brain to dementia. "We found ...

Researchers from the Paris Brain Institute and Sainte-Justine University Hospital in Montreal have, for the first time, ...

Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...

The blood–brain barrier (BBB) is meant to protect the brain from noxious agents; however, it also significantly hinders the delivery of therapeutics to the brain. Several strategies have been employed ...

Repeated head knocks cause long-term damage to the delicate blood-brain barrier, potentially driving chronic traumatic encephalopathy (CTE), a neurodegenerative condition that affects some former ...

Too much salt may inflame the brain, triggering hormones that push blood pressure higher. Scientists found this pathway could explain why many patients resist current hypertension drugs, pointing ...

A new blood marker reflects the extent of brain injury after an ischemic stroke and can predict patient outcomes months to years later. Strokes are a medical emergency, yet imaging can capture only ...
