Concussion Symptoms and Tests
A concussion is a type of brain injury caused by a blow to the head or body that results in the brain moving rapidly back and forth within the skull. It is a common injury that can occur in a variety of situations, including sports, falls, and motor vehicle accidents. Early detection and treatment of concussion are important to prevent long-term complications.
Concussion Symptoms
Concussion symptoms can vary widely and may not appear immediately after an injury. Common symptoms include:
| Physical symptoms | Cognitive symptoms | Emotional symptoms |
|---|---|---|
| Headache | Confusion | Irritability |
| Nausea or vomiting | Memory loss | Depression |
| Dizziness or balance problems | Difficulty concentrating | Anxiety |
| Blurred or double vision | Slowed reaction time | Mood changes |
Immediate and delayed signs of concussion include loss of consciousness, drowsiness, and sensitivity to light or noise. Gender and age can also affect the presentation and long-term effects of concussion symptoms.
Concussion Tests
Concussion tests are important for accurately diagnosing and managing concussion. There are several types of tests available:
| Physical examination | Imaging tests | Cognitive tests |
|---|---|---|
| Assessment of balance, coordination, and reflexes | X-rays, CT scans, and MRIs | Tests of memory, attention, and reaction time |
Concussion tests are an important tool in accurately diagnosing and managing concussion. There are several types of concussion tests available, including physical examination, imaging tests, and cognitive tests. In Canada, concussion tests can be found through various healthcare providers and clinics.

Online Concussion Tests
Online concussion tests are becoming more popular for their convenience and accessibility. There are several types of tests available:
| Symptom checklists | Cognitive tests | Balance and coordination tests |
|---|---|---|
| Questionnaires to assess symptoms | Tests of memory, attention, and reaction time | Assessment of balance and coordination through webcam or smartphone |
Online concussion tests can be a useful tool for individuals who suspect they may have a concussion, but they have limitations in terms of accuracy and privacy concerns.
Online concussion tests are designed to provide a convenient and accessible option for individuals who suspect they may have a concussion. These tests can be taken from a computer or mobile device, and typically involve a series of questions or tasks to assess cognitive function, balance, and coordination.
While online concussion tests may be a useful tool in identifying potential concussion, they are not a substitute for medical evaluation and diagnosis by a healthcare professional. It is important to seek medical attention if you suspect you have a concussion, regardless of the results of any online test.
Here are some examples of online concussion tests:

Baseline Concussion Testing
Baseline concussion testing is a pre-season assessment of an athlete’s cognitive function, balance, and coordination. It can help to establish a baseline for comparison in the event of a concussion. Types of tests used in baseline concussion testing include:
| Physical examination | Cognitive tests | Balance and coordination tests |
|---|---|---|
| Assessment of balance, coordination, and reflexes | Tests of memory, attention, and reaction time | Assessment of balance and coordination |
Baseline concussion testing is important for identifying and managing concussion in athletes, but periodic retesting may be necessary to ensure accuracy.
Whiplash Concussion
Whiplash concussion is a type of concussion caused by a sudden acceleration-deceleration movement of the head and neck. It is often associated with motor vehicle accidents and can have long-term effects. Symptoms of whiplash concussion include:
- Headache
- Neck pain and stiffness
- Dizziness or balance problems
- Memory loss or difficulty concentrating
Diagnosis and treatment of whiplash concussion may involve physical therapy, medication, and cognitive rehabilitation. It is important to seek medical attention if you suspect you have a whiplash concussion.
Sports and Concussions
Sports-related concussions are a significant concern, particularly in contact sports such as football and hockey. Risk factors for sports-related concussions include:
- Prior history of concussion
- Playing position
- Age
- Gender
Prevention and management of sports-related concussions can involve education, rule changes, and protective equipment. Technology, such as impact sensors and virtual reality training, may also have a role in preventing and managing concussions in sports.
Sports-related concussions are a significant concern across many sports, including both contact and non-contact sports. Here are some examples of sports and their concussion risk categories:
Not friendly to concussions:
- Football
- Rugby
- Ice Hockey
- Basketball
- Soccer
- Gymnastics
- Cheerleading
In these sports, athletes are at a higher risk of concussion due to the potential for head impacts from collisions with other players, falls, or direct blows to the head.
Friendly to concussions:
- Swimming
- Track and Field
- Cycling
- Tennis
- Volleyball
- Golf
In these sports, athletes are less likely to experience head impacts that could lead to concussion. However, all athletes should be aware of the potential for concussion and take appropriate precautions to prevent injury.
The risk of concussion in sports can vary based on a variety of factors, including the sport itself, the age and gender of the athletes, and the position played. For example, in football, linemen and linebackers are at higher risk for concussion due to the frequency and intensity of collisions during play.
Prevention and management of sports-related concussions can involve education, rule changes, and protective equipment. Helmets and mouthguards can help reduce the risk of concussion in some sports, while rule changes such as limiting contact or altering the playing surface may also help reduce the risk. However, no single approach can eliminate the risk of concussion entirely.
Continued research and education on sports-related concussions are needed to better understand the risk factors and improve prevention and management efforts across all sports.
FAQ
Common questions related to concussion symptoms and tests:
- What are the symptoms of a concussion?The symptoms of a concussion can vary widely and may include headache, nausea or vomiting, dizziness or balance problems, blurred or double vision, and sensitivity to light or noise. Physical, cognitive, and emotional symptoms may also be present.
