What happens in your body during a stroke? [infographic]

Posted on 12 September 2019

A stroke is a brain attack: a medical emergency that robs your brain of oxygen. The longer you go without specialised treatment, the more damage is done to your brain.

“The longer your brain goes without oxygen, the more brain cells you lose.” Dr Daniel Fiandeiro – Emergency Medicine Specialist: Mediclinic Pietermaritzburg

Strokes have immediate symptoms and long-term effects, says Dr Fiandeiro.

Doctors look for two things when diagnosing a stroke:

  1. Sudden onset
  2. Reduced function

This infographic explains why every minute counts when it comes to treating a stroke.
