Concussion Grades - Distinguishing Degrees of Concussions

Have you ever heard the terms “Grade 1 concussion,” “Grade 2 concussion” or “Grade 3 concussion” before?

Did you wonder what this “grade” refers to?

Concussions are a complex and sometimes misunderstood form of mild traumatic brain injury – though not all concussions are mild. The scale of concussion degree can range from mild to severe.

The Concussion Grading System

There’s an adage in concussion treatment that goes, “no two concussions are like.”

It’s true – every concussion patient has a different experience with their concussion journey, with regard to:

Concussion symptoms
Degree of concussion
Concussion recovery time
Long-term effects of concussion

It’s the second one, degree of concussion, on which we’re largely focusing today.

Degree of concussion is determined by a concussion grading system that is generally accepted around the world by doctors and providers of concussion treatment.

The concussion grading system goes as follows:

Grade 1 Concussion – Mild Concussion
Grade 2 Concussion – Moderate Concussion
Grade 3 Concussion – Severe Concussion

What do each of these concussion grades mean? How are they defined? Read on to find out!

Degrees of Concussion – At the Time of Injury and Beyond

When a concussion is incurred, both the immediate impact and the duration can vary greatly.

Grade 1 Concussion – Minor Concussions, Many Symptoms Can Persist

In a Grade 1 Concussion, a loss of consciousness does NOT occur. The person suffering the concussion can experience some or all of the following concussion symptoms in the minutes, hours and days following the concussion injury:

Headache
Dizziness
Nausea
Memory Loss
Difficulty Focusing

Grade 1 concussions tend to occur most frequently in minor (relatively speaking) car accidents and sports injuries.

Grade 2 Concussion – Mid-Grade Concussions with Enhanced Symptoms

The symptom a Grade 2 Concussion can be similar, but the degree and duration of this concussion tend to be higher. Grade 2 Concussion symptoms include the possible symptoms of a Grade 1 concussion, as well as:

Ringing in the Ears
Momentary Amnesia
Irritability

Many people suffering a Grade 2 Concussion experience a temporary loss of consciousness, for as little as a few seconds and possibly up to several minutes.

Grade 3 Concussion – A Severe Concussion, Lasting Longer with Greater Impact

A Grade 3 Concussion is generally considered the most severe of this type of traumatic brain injury.

As in Grade 2 concussions, the patient who suffers a Grade 3 Concussion be unconscious – but for even longer, even more than five minutes.

Similar symptoms to concussions of grades 1 & 2 can occur; on top of these are:

Amnesia for 24 Hours or More
Seeing Stars
Vomiting

Grade 3 Concussions carry the highest risk for long-term or even permanent concussion symptoms. The recovery time for this concussion is also longer, up to two weeks or more.
