That's a very sad article, Kat.
When I was in the full blush of post-concussive syndrome Colin was adamant from his hockey experience that I was fucked up and would be fucked up for a good long while.
He was more blunt about it than most of the doctors. Oh, in retrospect they called it a severe concussion, but really--they need to say that up front so I don't think I'm just being whiny and fragile.
I had a couple people at krav tell me to basically butch it up (the loudest got concussed a few weeks later, when a female student knocked the crap out of him--he was suddenly sympathetic to the impossibility of faking alertness, and the strange impact on speech and memory) and others react like I'd never be able to walk unassisted again.
The truth lay somewhere in the middle, but those months I'd count as being fully in the syndrome? Fucking miserable. Worse than the migraines now--I could have more than one headache at a time, and feel them moving around. If my migraines now are like one long hangover, post-concussive syndrome is the morning after the night before with a whole lot of poor judgment and cheap liquor.
I am now the centre expert on concussions, and guys who would have ignored them are maybe paying a little more attention.
