The effects of a brain injury

The brain controls everything we do. It tells the heart to pump, the kidneys to filter. It helps us to walk, tells us how to put one foot in front of the other, what muscles to contract and extend. It tells us when we're hungry and when we're thirsty and how to feed ourselves, right up to complex things such as mathematical equations. Every thought, everything we do is through the brain. In fact, the brain is the biggest sex organ we have. It's the brain that tells us when we like somebody and when we dislike somebody. 

After a brain injury, absolutely anything that we do can be affected, including our personality. We may not be able to walk. We may not be able to speak. We might have a different language. We might say the wrong word in the wrong place. We might be a very angry person when we were a calm person before. Everything that we do can be affected. Somebody might have lots of conditions and functions they can't do now. Other people might just have something small, maybe a short-term memory loss. Maybe just one problem. But quite often it's a combination of problems, which makes life very difficult. A person with a brain injury can experience all these problems, or they might just have one, such as short-term memory loss or not being able to walk. It can still be devastating.
