How a stroke affects the brain and body

The brain is the control centre for the body and everything we do. Different parts of the brain control different parts of the body.
The brain is divided into two halves. One side of the brain controls the opposite side of the body. For example, the left side of the brain controls the right side of the body.




The brain not only controls movement and sensation but also controls how we think, feel and communicate.
The two sides have slightly different functions.  For most people this is how the functions are divided

Drawing of a brain

How the body is affected by a stroke depends on how much brain tissue has been damaged and where that damage occurs.

  • A stroke is sudden and its effects are felt immediately.
  • Stroke causes some brain tissue to die. 
  • A stroke can be anywhere in the brain and can be very small or very big.
  • The site and size of the damage will determine what functions are affected and to what extent.
