Actually, very few neuro'' understand anything about concussion besides rest. The best recommend quiet rest but that is few. The biggest difference is the critical mass provided by the Sports Legacy Institute, an organization founded by ex-NFL players. The professional football players association has sued the National Football League for poor information and lack of care for those injured by concussions.

This has caused a groundswell of research and information since 2007 that really started late 1990's.

Our system of healthcare, as it has become a runaway financial freight train, has allowed those with extensive employer fund health care an inordinate amount of diagnostics and treatments whether they are valid or not. This allows the doctors to try many therapies.

A great number of therapies are beyond medical justification but are offered because the health insurance company will pay the bills. The 'off label' use of medications are not strictly regulated so there is a 'try this and see if it helps' method of medication use. The need to maximize profits by the health care provider allows for excesses in care.

Of all of the treatments mentioned, quiet rest is still the gold standard. Our military and Veterans Administration have been researching concussion/mTBI to extreme levels but do not provide a similar level of access to treatment because they have budget constraints.

We still struggle with consistency of diagnostics and treatment due to decades of liability insurance companies fighting against court recognition of prolonged concussion symptoms. The military and VA have recently let a contract for the NeuroTrauma Foundation to create a diagnostic definition of concussion. So, you can see that we are still in the early stages of normalization of information.
