Replying to concussions

I think I'm getting concussion prone like eric lindros. that sucks eh? I keep wiping out and seeing stars. I was wondering if any of you have usefull information. Like do some helmets work any better than others? like are the big motocross style seth morrison ones any more protective than others? Its not even from just hitting my brain on a rail or anything, just some wipeouts give me whiplash and I see stars. any ideas?
