Concussion Myths: Facts Straight From the Experts

We recently met with our concussion specialists & brain injury therapists to discuss the following common misconceptions about concussions; All of which were found to be not true.

After reading through, if you feel we have left out any other important concussion myths, please be sure to let us know by leaving a message in the suggestion box.

These Are the Top 11 Concussion Myths

  1. You can only get a concussion from a hit to the head – A concussion is caused when the brain begins to shift back and forth within the skull leading to axon shearing, also known as an acceleration injury. In many cases, a strong impact to the body can transmit enough force to the head, directly resulting in a concussion.
  2. Helmets will prevent concussions in contact sports – Helmets have not been proven to reduce the incident rate of a concussion due to the mechanism of the injury. They are designed to protect against skull fractures and lacerations, therefore, should still always be worn in high-impact sports that are associated more commonly with injury.
  3. Mouthguards can prevent concussions from occurring – Mouthguards can reduce oral and dental injuries, but like helmets, there is limited research or evidence to support that they can prevent concussions.
  4. Concussions only happen in high contact sports – While there are a significant number of concussions in contact sports such as rugby, hockey and football, concussions in other “non-contact” sports frequently happen. Sources show that head injuries commonly occur in sports such as soccer, cycling, skiing, basketball, baseball, dance and gymnastics.
  5. After a concussion, it is best to isolate yourself in a dark room – Strict rest was once a common way to manage a concussion, but recent research recommends a short period of symptom-limited rest (24 to 48 hours). Following this period, a graded return to activity is advised. If someone is experiencing sensitivity to light, vision therapy or vestibular therapy may help aid in recovery.
  6. A concussion is when the brain becomes bruised – There are no objective findings on imaging (CT scan, MRI, X-ray, etc.) because there is no structural damage or injury to the outer grey matter. A concussion is a functional injury within the white matter, which leads to a metabolic energy crisis and cellular dysregulation.
  7. It’s important not to go to sleep after getting a concussion – This idea stemmed from precautions with those who have had a brain bleed. It is difficult to assess a person’s symptoms or if there has been a regression while asleep so recommendations are to wake every hour to check. These types of injuries will show red flag symptoms within 3-6 hours. If there is no concern for this, the individual may sleep. If there is a concern or uncertainty, the individual should be taken to the emergency department.
  8. Concussions cause long-term memory loss or Chronic Traumatic Encephalopathy (CTE) – Scientific studies linking concussions and long-term effects are still in the early stages and no definitive conclusions can be made. There are a great number of other factors which are poorly covered in the media.
  9. Concussions treatments and recovery times are all the same – No two concussions are identical. There are 6 different clinical trajectories – visual, cervical, vestibular, physiologic, migraine, and mood – for a concussion but each patient presents differently due to other factors unique to the injury.
  10. To be classified as a real concussion, there needs to be a loss of consciousness – It is estimated that more than 90% of concussions do not result in a loss of consciousness.
  11. Having one concussion places you at increased risk for future concussions – Proper clinical management is the best form of prevention; recovery from one should not put an athlete at risk for another.

Weight-Bearing Interventions In Stroke Recovery

Experiencing a stroke can lead to motor impairments, including hemiparesis, which is a weakness or paralysis on one side of the body. These impairments can often impact an individual’s ability to perform daily activities such as dressing, bathing, driving, walking, and using the restroom. Traditionally, physical and occupational therapy focus on helping people adapt to these changes; however, research is now recommending methods that help recover function. Weight-bearing, or putting weight on an individual’s affected arm or leg, supports stroke recovery by helping the brain and body work better together to improve balance, coordination, and strength.

Making Your Bathroom Safer

The bathroom may be one of the smallest rooms in the house, but it’s often the most hazardous—especially for those with mobility challenges, balance issues, or those recovering from injury or surgery.
