Brain blood flow, or cerebral blood flow, refers to the blood supply that reaches your brain during a given period of time. Your brain needs almost 20% of the blood supply provided by each heartbeat.
A steady flow of blood brings oxygen, glucose, and nutrients to the brain, and carries carbon dioxide, lactic acid, and other metabolic waste products away from the brain.
But when brain blood flow is hindered, cognitive problems can arise.
