Understanding Concussion
To help you better understand, recognise and be proactive in the treatment of Concussion amongst athletes but also everyday individuals
What is Concussion?
A concussion is a form of mild traumatic brain injury (mTBI) caused by a direct or indirect blow to the head or body that affects brain function. Symptoms may appear immediately or gradually, and every concussion is different.
​
While most people recover fully, up to 30% experience prolonged symptoms that require active rehabilitation and expert support.
How do you Recognise Concussion?
Recognising concussion can be difficult. It is important to know when to suspect concussion, because appropriate response and management can help prevent further injury or even death. There are several possible symptoms and signs, but they can be subtle and they are not specific only to concussion.
​
Onlookers should suspect concussion when an injury results in a knock to the head or body that transmits a force to the head. A hard knock is not required—concussion can occur from relatively minor knocks.
What Causes a concussion
Since your brain is a soft organ, it needs your skull to protect it. And even though your brain sits in fluid that acts like a cushion, that cushion isn't enough when your head or body takes a hit.
​
A strong impact can cause your brain to shake or collide with the inside of your skull. Imagine your brain as an egg yolk moving freely within an eggshell. This movement can damage your brain, which is why a concussion is classified as a type of brain injury.
​
There are many ways to get a concussion that aren't related to athletic injuries. Some common causes of concussion include fights, falls, playground injuries, car crashes, and bike accidents.

Types of Concussion
This type of concussion makes it hard to turn off your thoughts. You might have excessive worry and feel restless. It can also make social interactions difficult. But your symptoms may get worse if you isolate yourself and avoid normal activities.
When to go to the Emergency Department?
If symptoms worsen or you experience red flags like repeated vomiting, confusion, or seizure, you should seek immediate emergency care.
