It most certainly has been! But the brain can be like that: do not underestimate the power of neural networking! I have always felt however that the doctors' estimates were too pessimistic. I can only see things getting better.
As for neurologists, to be fair I know a few really, really good ones, but some in my opinion also give surprisingly little "bang for your buck", so to speak... With neursosurgeons again I know a few really good ones (I know one who can dive right in there and clip an aneurysm in the most tricky, inaccessible part of the brain --estimated patient survival rate: 50%; estimated chance of at least partial blindness or paralysis about 75%-- and the patient comes out with no symptoms whatsoever. I mean, that man is
good), but I also suspect that some need to psychologically compensate for the fact that really, they can't
do all that much about brain injury. Nanotech is still a century or so away...
