What happens to the brain during a stroke? What happens to the brain during a stroke?

A stroke occurs when bleeding interrupts the blood flow in an organ.

It generally refers to the symptoms of a stroke or a cerebrovascular accident (CVA).

A stroke can manifest in two ways: the first is from a thrombus that is clogging an artery and blocking the blood flow to the brain, the second cause is hemorrhaging from a ruptured artery in the brain or on the surface of the brain.

In both cases, the brain goes without oxygen, which causes brain cells to die in a matter of minutes. It is therefore very important to detect any signs of a cerebral vascular accident as soon as possible and seek out immediate medical attention.

According to the National Institute of Neurological Disorders and Stroke, the most common symptoms for having a stroke are:

  • Sudden numbness or weakness in the face, arm, or leg, especially if it is on only one side of the body.
  • Sudden confusion, difficulties speaking or not understanding what is being said.
  • Sudden vision problems in one or both eyes as well as problems walking, dizziness, and a loss of balance or coordination. 
  • Severe and sudden headache without any known cause.
