As vessels become more porous, researchers say, they allow toxins in the bloodstream to reach, and damage, delicate brain cells and raise the risk for dementia.

Gender differences define how the human brain ages, and telltale biomarkers in the blood may be strongly suggestive of cognitive impairment and dementia, according to a comprehensive new study ...

Disease of the microscopic blood vessels that feed the white matter of our brain is associated with worse cognitive function and memory deficits in individuals with Alzheimer's, scientists report.

They then observed vasomotion in action within mice with amyloid-beta plaques built up in the walls of their brain blood vessels. Here, they found the pulsations to be impeded and clearance rates ...

What the MRI shows is a disease of the blood vessels of the brain caused by cholesterol plaque. High blood pressure, smoking, high blood cholesterol, family history, and other factors put people ...

In the brain, not all blood flow is created equal. RIKEN researchers have developed a detailed cortical layer map of the blood vessels that weave through the brain of macaque monkeys. It reveals ...

Blood flow fluctuations are therefore a sign of an increased brain activity and can be used for scanning brain tissues – using functional magnetic resonance imaging (fMRI). Important questions ...

"The brain's vasculature, or blood vessel cells, genes, and pathways, is important for the proper functioning of the healthy early developing and adult brain, as well as for a variety of brain ...

Researchers have developed a microrobot that can be navigated through the brain's blood vessels using ultrasound. Del Campo Fonseca et al. (edited) 2 / 2.
