yes,ive been a severe head banger [banging my head on hard objects like the wall, not a head banger in the metal/rock sense]since ive had control of my own head and ive suffered many concusions, with a whole host of side effects such as losing skills,major tinnitus and getting more agressive and irritable.i started suffering from severe depression at 15,i dont know whether that was a puberty thing or part of the concussions.
my neurologist has prescribed me padded helmets for years but it cant change the past.
