There has been a very accurate brain injury diagnostic tool available for over a decade. qEEG has the ability to diagnose brain injury with a 97% or higher reliability. It has been discounted because of one article written by a neurologist with an ax to grind back in 1997. The article has been soundly discredited but the damage was already done.

Maybe the Brain Trauma Foundation can use some of its federal grant money to promote the value of qEEG as a diagnostic tool.
