CONCUSSION TESTING

UBC study urges consistency

What is a concussion?

According to the U.S. Centers for Disease Control, a concussion is the diagnosis when an outside force on the head — a bump, blow or even just a jolt — causes the head and brain to move quickly back-and-forth, leading to chemical changes in the brain. It sometimes stretches and damages brain cells.

What are the dangers?

According to the CDC, “a severe brain injury can affect all aspects of people's lives, including relationships with family and friends, as well as the ability to work or be employed, do household chores, drive and/or do other normal daily activities.” Brain Injury Canada says: “While the majority of people recover within one month, in some cases symptoms resolve more slowly or may persist longer than expected. Prompt medical assessment and management can help diagnose concussions and ensure patients are provided with proper education and guidance as well as treatment as needed.”

What are common symptoms?

Headaches, nausea, balance problems or dizziness, double or blurry vision, sensitivity to light or noise, moving clumsily or feeling sluggish or groggy, feeling confused or having problems concentrating and following instructions, having memory problems, or an overall sense of just not feeling right. According to Brain Injury Canada, more serious symptoms include seizures, losing consciousness or displaying mood, behavioural or personality changes.
