Did you mention the NHS apt to that Dr?

If he is for the insurance then he has an agenda: he is paid to medically prove your injuries are less so there is less payout. In the uk you do not need to rely on this.

I think he was hinting at you to make sure you get the right tests with your NHS neurologist. Those independant results can be included in your insurance claim. (As well as, hopefully, a plan to get you better!)

I'm still awaiting my first apt, with an NHS neurologist. I'm wondering the same things as you.

Though it is certainly possibly to get a concussion without direct impact of an object. In the instance of an object that is the mechanism of force, if say in a car it is the cars momentum that is the force that bruises your brain.
