But is the amount of G's a car achieves by sudden braking the same amount of G's at which your brain accelerates/decelerates in your head? Wouldn't the amount of G's to the brain depend more on how the body reacts to the jolt - than the jolt itself? How can we be sure the whipping of the head isn't enough to cause injury in this situation?

Looking for clarity on this as the same thing happened to me yesterday. I am 8 months PCS.

Thanks!

I don’t have the expertise to try and answer that question but thinking about it logically, if stuff like that could cause tbis then everyone in the world would have suffered many many tbis in their life. Watch kids playing in the park, they are falling all over the place constantly

I think trusting our bodies and telling ourselves we aren’t as weak as think can help a lot. When something bad happens to me like hitting my head or falling on ice, instead of panicking I try and flip the narrative in my head and say, ‘by this happening I’m proving to myself I can take it and that I’m stronger then I thought’. It’s liberating facing your worst fears and realizing they aren’t as scary as you previously thought. Hope that makes sense.

I think there are a few factors that lead to a lot of confusion around this particular topic on this forum. If you ask any leading concussion neurologist this question, they will tell you it is absolutely not possible to cause structural damage to the brain or trigger a concussion from an event like this. It is, however, possible to trigger legitimate (sometimes long-lasting) neurological symptoms through either migraine pathology (happened to me--from a large pothole, not fast braking) or the exacerbation of an existing neck injury OR a panic attack.

Some people are also just very worried about "brain damage" without symptoms actually appearing. Which leads to a lot of worried posts.

I can say definitely to everyone in here, you are not going to get CTE from driving a car Everyone drives a car. Everyone brakes to avoid the deer. Everyone smacks their head on the door frame getting out. If you are having legitimate long-lasting neurological symptoms after events like this, you probably have something else going on and probably need to get your neck checked out and see a doc about the possibility of migraines with a vestibular trigger. Both of these things can give you symptoms that "feel like a new concussion", by the way.
