A new cause of brain hemorrhage has been identified

New findings open the door to treatments that ensure the movement of red blood cells through brain capillaries

In a significant development for brain health, scientists have demonstrated for the first time how hemorrhages can occur due to a faulty interaction between aged red blood cells and narrow capillaries. Until now, the cause of this serious condition has been brain bleeding that results from injured or damaged blood vessels.

Common dietary nutrient blasts blood vessel plaques in study

Posted on by

While statin drugs are good at controlling plaques in blood vessels, they can’t eliminate them once they are established. But researchers may have just found a way to blast the circulatory system clean using a common nutrient found in many foods.Contin… Continue reading Common dietary nutrient blasts blood vessel plaques in study→

Fluctuating blood pressure increases risk of dementia in older people

Posted on by

A new study has found that short blood pressure fluctuations – across a day or several days – increase the risk of dementia in older adults. The findings suggest that blood pressure variability could serve as an early clinical marker of cognitive impai… Continue reading Fluctuating blood pressure increases risk of dementia in older people→

Molecule patches leaks in blood-brain barrier to prevent MS or Alzheimer’s

A new study has identified promising molecules that could help patch up leaks in the blood-brain barrier

Being the control center of the body, your brain needs strong security against circulating pathogens or toxins. The blood-brain barrier (BBB) performs this vital function, but it can become “leaky.” Now, scientists at Stanford have identified therapeutic molecules that could help patch it up, to potentially prevent neurological diseases.

Melt electrowriting takes us closer to artificial blood vessels

Posted on by

Researchers in the Netherlands have combined two different 3D-printing techniques to produce artificial blood vessel prototypes. The process created tubes that can be covered in live cells while retaining the strength they need to function under pressu… Continue reading Melt electrowriting takes us closer to artificial blood vessels→

Experimental device breaks up blood clots using twisted ultrasound

Posted on by

It goes without saying that if someone has a blood clot in their brain, that clot should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existin… Continue reading Experimental device breaks up blood clots using twisted ultrasound→

Manufactured blood vessels mature naturally once in the body

Posted on by

Damage to blood vessels that leaves them blocked or otherwise impeded can leave no option other than surgical replacement. Traditionally, this can involve vessels from a donor or harvested from elsewhere in the patient’s body, but lately we’re seeing h… Continue reading Manufactured blood vessels mature naturally once in the body→

Blood vessel discovery points to alternative cause of Alzheimer’s dementia

New research hypothesizes narrowing blood vessels in the brain plays a role in the cognitive decline associated with Alzheimer's disease

Following yet another failed clinical trial testing a novel drug designed to break up the aggregations of toxic proteins thought to be the cause of Alzheimer’s disease, a new study suggests we look to a different part of the brain in the hopes of finding a treatment. Led by researchers from the University of Manchester the new study found disruptions to blood vessels in the brain may be contributing to the neurodegeneration seen in Alzheimer’s.
