A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a ...

All it takes is the flip of a protein "switch" within the tiny wire-like capillaries of the brain to increase the blood flow that ensures optimal brain function. New research has uncovered that ...

Thanks to the increasing availability of point-of-care (POC) testing, the use of capillary blood (fingerstick) sampling worldwide is growing. Anemia affects around 25% of the global population. Its ...

The brain is packed with neurons that are constantly in need of power, but there isn't really anywhere to store energy there. So the brain has a network of blood vessels that constantly supply it with ...

When you sit quietly for a moment listening to your heart pump blood through your body, do you think about blood vessels as a firehose drenching your organs and brain with red blood cells full of ...

Replacing a missing brain lipid may calm overactive blood vessels and restore healthy blood flow—opening a new path toward treating dementia.

The brain is perhaps the most sensitive organ with respect to changes in blood flow and oxygen supply. Even brief interruptions in capillary flow (or "stalling") can indicate acute neurological issues ...

Winter's chill triggers dangerous physiological changes, increasing stroke risk. Cold constricts blood vessels, raising blood ...

3D microvessels have been created to observe how red blood cells transit ultra-small blood vessels. They squeeze single-file through microvessels to bring oxygen and nutrients. Red cells burdened with ...

Brain aneurysms, often silent threats, can rupture unexpectedly, causing life-threatening hemorrhages. Weakened blood vessels ...
