The research,publishedin theJournal of the American Heart Association, analyzed the association between young adults' adherence to metrics for measuringcardiovascular healthand early indicators of plaque buildup in the carotid arteries—the arteries in the neck that supply blood to the brain. Blockages...
During an episode of migraine, the arteries in the head, particularly in the temple, widen. Then, the widened arteries stretch the nerve fibers that surround the arteries, causing them to send signals to the brain. As a result, the signals cause pain and stimulate the SNS or sympathetic ner...

Cerebral blood flow, or CBF, is the circulation of blood through the brain. Blood flows into the brain from the vertebral and carotid arteries in the neck, and leaves mainly through the internal jugular veins, which are also situated in the neck. Inside the brain, cerebral circulation takes ...
What are the signs and symptoms of CAD in women?You may not have any symptoms at first. Symptoms may begin slowly but increase quickly as plaque builds up in your arteries. You may not notice symptoms until the artery starts to become blocked. Women often do not have the common signs ...
