I have had the same experience with my neurologist, he doesn't know or he doesn't care.
It gets even worse than that. I went to see the post concussion work group in the Danish center for brain damage rehabilitation. They want me to participate in a new research program where they use physical therapy like weight lifting and cardio training to see if people suffering from PCS improves.
I asked them if they wanted to try the buffalo university sub symptom threshold recovery program themselves, but of course she never heard of it. Their plan was to make people exercise a lot and do weight lifting 3-4 times a week for 20 weeks to see if they got better. I kindly had to explain to her that exercise actually makes it worse unless it is strictly monitored. Well she never heard of that and they didnt plan on monitoring anybody
Good luck with that...
