A hidden protein buildup in brain blood vessels may quietly quadruple dementia risk—often without a stroke as warning.

Cerebral amyloid angiopathy (CAA) is a condition where protein (called amyloid) builds up in the brain, making blood vessels weak. People with CAA are four times more likely to develop dementia within ...

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 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 ...

After collapsing with a seizure, doctors discovered an arteriovenous malformation (AVM) in Steven’s brain. It is an extremely ...

Blood vessels are more than just pathways for oxygen and nutrients; they also host communicative processes that guide brain development and sustain its function. These vascular-neuronal interfaces are ...

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 ...

Published January 7 in the journal Nature, one paper tackled the age-old problem of nature’s construction with a bit of a twist: it suggests that living networks, like our brain, may use some of the ...

A newly identified lymphatic drainage pathway along the middle meningeal artery reveals how the human brain clears waste. How does the brain clear away waste? This task is handled by the brain’s ...

For the first time, scientists have used real-time imaging to track tiny pieces of microplastics as they moved through the brain blood vessels of mice. In experiments, the international team of ...

Think your sugar-free soda is healthier than regular? New research shows erythritol, a common sugar substitute, damages the cells lining blood vessels in your brain.
