Frequently Asked Questions

White matter is the communication network of the brain comprised of millions of delicate nerve fibers called axons. Repeated hits to the head, even smaller impacts, can cause the brain to move inside the skull, stretching, compressing, or tearing these delicate nerve fibers. The short- and long-term effects of these structural changes are not known at this time and are currently being studied.

NeuroShield is the first technology that uses the body’s own physiology to help stabilize the brain. The device applies light pressure to the neck, which in turn mildly increases blood volume to the venous structures around the brain. This appears to reduce the movement of the brain inside the skull.

The rate of blood flow into and out of the brain is not affected by wearing the NeuroShield collar. In fact, the blood volume increase in the brain is similar to the increase experienced due to gravity while lying down. There is no indication that the small amount of increased blood volume created by NeuroShield has any negative impacts.

As part of the development of the NeuroShield collar, studies were performed with athletes executing peak level activity. No significant differences in physiological measurements between collared and non-collared athletes were identified, confirming the collar did not restrict performance. In addition, athletes who wore the collar over the course of a sports season reported that it did not impede them in any way.

It’s not always about the big hit. Repeated hits to the head, even smaller impacts, have been shown to result in structural changes to an athlete’s brain over the course of a season. The short- and long-term effects of these changes remain unknown at this time and are currently being studied. The NeuroShield collar helps to protect the brain from these changes. The NeuroShield collar does not, however, prevent concussions.

The technology behind NeuroShield was first identified by Dr. David Smith and initially researched by him, Dr. Joseph Fisher and Dr. Julian Bailes. These leading doctors identified the movement of the brain inside the skull, or “slosh”, as a key cause of structural changes to the brain. By developing a simple device worn on the neck, the doctors determined they could help reduce the movement of the brain inside the skull, therefore reducing structural changes to the brain.

The NeuroShield collar can be worn for up to four hours at a time. The NeuroShield collar has been qualified for one year of use based on the expected participation levels and collar usage of an average athlete.

There are no known side effects.

Some people put the collar on and feel nothing except the light compression force on their neck. Others may feel a flush feeling that usually subsides as the body acclimates to the collar.

NeuroShield has been tested with individuals from age seven to 60.

There have been several studies conducted on the effectiveness of the NeuroShield collar and to date each study has shown the device to be effective at reducing structural changes to the brain due to sports-related impacts. The short- and long-term effects of these structural changes are not known at this time and are currently being studied. The collar may not have the intended effect for a small subset of the population. The NeuroShield does not, however, prevent concussions.

The NeuroShield collar is licensed for sale in Canada by Health Canada. We are currently working with the necessary government regulatory bodies in several additional countries and once we have obtained approval, NeuroShield will be available for sale in those countries.

Hockey Canada has indicated that NeuroShield complies with the rules of the game as written.
