Male Neurological Exam

I have a neurological exam scheduled for this Friday. Due to my symptoms, I believe the doctor will perform a full neurological evaluation, or at least check upper and lower limbs. I'm wondering if he'll have me in my underwear or a gown. I've seen some educational videos online and usually guys are in their underwear because the doctor needs easy access to arms, legs, etc. I hate gowns and I'm hoping they don't give me one. Should I just be bold, ditch the gown and strip to my underwear anyway?

I was in an accident at work that resulted in a concussion, so I had a complete neurological exam a couple of weeks later. I was in my briefs only for most of it (except for the EEG). A gown would have been cumbersome, so I would agree that it would be reasonable to decline one if offered. It's not like a regular physical.
