This reduces blood flow to the brain, causing attention deficits, memory loss, and impaired learning ability. Professor Peter Weissberg, medical director of the British Heart Foundation, said: "This paper adds to the growing body of evidence that marijuana has important and persistent physiological effects on blood flow to the brain that may ... An aneurysm is a small blood filled bulge which develops in an enlarged part of the artery wall. This occurs as a result of uncontrolled high blood pressure. An increased blood flow through the artery puts undue pressure on it which then weakens it over time.
Blood Flow to the Brain Stem in Rats Kenichiro Fujii, MD; Donald D. Heistad, MD; and Frank M. Farad, PhD Large arteries contribute to the regulation of cerebral blood flow. The goal of this study was to examine the effects of changes in diameter of the basilar artery on blood flow to the brain stem. In FMS, research shows abnormal blood-flow patterns in the brain, with more than normal in some areas and less than normal in others. We don't know the specific effects of this, but researchers do know that blood flow has a significant impact on brain function.
