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 ...

The blood-brain and blood-retinal barriers are protective systems that prevent harmful substances from entering the brain and ...

The brain's health depends on more than just its neurons. A complex network of blood vessels and immune cells acts as the brain's dedicated guardians-controlling what enters, cleaning up waste, and ...

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer’s disease and ...

A new study identifies molecular factors that promote small vessel disease – and an active drug that can restore impaired vascular functions. Researchers at the LMU University Hospital have uncovered ...

Scientists have discovered that a part of the brain may be behind high blood pressure. The lateral parafacial region sits in ...

Reduced levels of a critical protein are linked to devastating brain diseases like Alzheimer's, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). Surprisingly, the protein shortage ...

Microvessels form the blood-brain barrier, a network that regulates molecular transfer between the vasculature and brain parenchyma. In cerebral small vessel disease (SVD), a leading cause of stroke ...

In a proof-of-concept study, researchers from the Keck School of Medicine of USC and the California Institute of Technology ...

Strokes are a medical emergency, yet imaging can capture only snapshots of how brain damage develops in the hours and days ...

Erythritol damages brain blood vessel cells, increasing risk of blood clots and stroke in lab studies. It reduces nitric oxide and raises endothelin-1, leading to vessel narrowing and reduced ...

Hypertension is the most common medical condition in the United States, affecting an estimated 120 million adults, or nearly ...
