Concussion | Symptoms & Support

What Is a Concussion?

A concussion is classified as a type of mild traumatic brain injury (mTBI) that occurs when the brain is jolted or shaken, often due to a fall, bump, or minor collision. It is considered serious, even though most people recover fully over time. Concussions frequently happen without loss of consciousness, and symptoms may not appear immediately, which can lead to the injury going unnoticed—sometimes called a “silent” concussion.

Concussions should not be ignored and medical assistance is essential to avoid long-term effects. You can check concussion symptoms in our handy checker below.

Common Causes of Concussion

Concussion can arise from a variety of everyday incidents that may seem minor at the time. Common causes include:

Falls
Sports-related collisions
Car accidents
Accidents at work

Children, in particular, experience accidents frequently, and these events are often dismissed as typical childhood mishaps. However, symptoms such as headaches, memory problems, or mood changes may appear later in life—and they may never be recognized as connected to the original injury.

Symptoms of Concussion

There are many symptoms of concussion that can develop over 1 to 2 weeks after the head injury. If you have recently suffered a head injury and your experiencing any of the following symptoms – contact a member of the team.
