3 shared Misconceptions About Concussions Seen at the York Regional Co…
1. You have to hit your head to get a concussion
Many of our patients don’t hit their heads and nevertheless sustain a concussion. A whiplash mechanism of energy can nevertheless generate enough force to cause a concussion. One’s brain is floating in cerebrospinal fluid and so a whiplash injury can cause it to shake/twist and abut against the skull. Although most consider a force of 95g to be a threshold for concussions, there are many situations of concussions with a lesser force and many situations of those who persevere greater forces and don’t sustain concussions, e.g. Football players frequently confront blows of over 100g of force. The details of the discrepancy are not thoroughly known however. So if the force transmitted to the brain is sufficiently sudden, whether on hits the head or not, a concussion may occur.

While many patients feel less vigorous after a concussion and rest is promoted, they shouldn’t feel obligated to stay in a dark room to “heal their concussions”. In fact, after the first 2-3 days, studies are showing that light physical activity and cognitive responsibilities can help accelerate healing. Withdrawing from activities of life thoroughly, and furthermore, staying in a dark room, will have a disturbing effect:

• It will cause you forgo many opportunities for cognitive stimulation that can help you retrieve.
Sometimes, patients are sensitive to light. This may be due to the brightness of the light or the kind of lighting (e.g. fluorescent lighting). It is best to avoid these as they aggravate your symptoms and may hinder your involvement in other therapeutic activities. It is best to seek the help of a concussion expert to guide you on your road to recovery.
