The U.K doesn't have any of these specialised concussion clinics. It seems like our national health system is practically useless for any problem in which you are not actually dying. If you are lucky enough to able able to afford private health care here, you may find a specialist with an interest. To be honest, the U.S seems to be streets ahead in terms of offering diagnostics and treatments for concussion. I've been to many Doctors, and it's embarrassing how little they know, or what to do with you.
