There is a simple reason why doctors know so little about concussions.

First: There is very little the Medical Doctors can do to help the PCS patient. There are no drugs approved for the treatment of concussion so the drug companies do not support the care of the PCS patient either.

Second: Since many concussions do not cause lasting symptoms, they think that all concussions should have no lasting symptoms. Also, by the time many of the delayed concussion symptoms show up, they are attributed to psychological causes.

Third: The liability insurance industry has thrown big money behind the denial of concussion as they defend against those injured in auto accidents.

Fourth: The sports doctors have been paid to get players back on the field for the financial gain of the professional sports team or the collegiate sports team.

Fifth: Very few neurologists have any skills at diagnosing any ailment that is not imageable on an X-ray, CT, MRI, EEG, or EMG, etc. If it does not show up on one of these imaging systems, it does not exist. The qEEG has a high reliability (95% and above) at diagnosing concussion but the insurance companies and Neurological Medical Associations have been successful at discrediting this fact.

Sixth: Because of the above, there are many old wives' tales that have been accepted as medical fact, such as any concussion with no Loss of Consciousness (LOC) will recover 100% with no after effects.

Seventh: Now, with most health care systems using a managed care protocol, there are many roadblocks to follow-up care of those who are diagnosed with a concussion.

btw, One of the big problems with the Canadian health care system is free services get overloaded and then many of the best doctors leave Canada to practice in the USA.
