If blood does not reach any part of the brain suddenly, then the person may have a stroke (Stroke). The blood flow in the brain serves as oxygen. This is just like when the blood supply in the heart can cause a heart attack. Hemorrhagic stroke occurs when a blood vessel leaks or damages in your brain. Similarly, if there is no blood flow to the brain, a 'brain attack' or stroke or brain stroke disease can occur.
