I remember coming by a paper classing these type of injuries, try scholar

Contrary to popular opinion, there is actually no evidence that you are actually more prone to suffering a concussion with less force if you've had a previous one. In fact, the one study that I've seen on this suggests that this is not the case.

@@CompleteConcussions Thanks for responding! That’s super surprising to hear! All of my doctors have always explained that I’m more prone to a concussion due to my history. That’ll definitely ease my nerves about sustaining another one.

@@codycan27 It's a common misconception. The research shows that those who have had a previous concussion (in sport) are more likely to suffer subsequent ones. This has led people to (mistakenly in my opinion) think that this means that the brain has become more susceptible...BUT...there are many factors that are not considered in most of these studies (body size, risk taking behaviour, playing position, etc.). Wide receivers are more likely to get concussed than linemen...so if you are a receiver and you've had a concussion and we are comparing you to a lineman with no concussion, it is more likely that you will get another concussion before the lineman gets one. Is this because your brain is more susceptible? Possibly...but a far more likely answer is that the fact that you are a wide receiver matters more than anything else. Same goes for playing style. Wayne Gretzky was able to sit back, anticipate the action, and avoid so much contact....Daniel Carcillo fought a bunch of people. So if Carcillo has had a previous concussion and Wayne had not, who do you think is still more likely to get a concussion? Carcillo...and is this because his brain is susceptible or because he plays the type of game that increases his concussion risk? I would argue the latter. As I mentioned in my first comment, the first study (and only as far as I'm aware...and I pay close attention) that looked at actual susceptibility in previously concussed individuals found that they actually get concussed at the same force as those with no previous concussions. You should never hang your hat on one study but we also have to go with the best available evidence we have at the time...and at this time, I wouldn't worry too much about it :). Hope this helps!

@@CompleteConcussions That makes total sense, I had a feeling that this sort of testing would be skewed. Thank you so much for the great explanation!

The consensus is that PCS is not caused by structural changes at all. There are some studies which show white matter issues and white/gray matter atrophy in PCS vs. healthy controls...but these same findings are found in ppl with MSK issues, depression, anxiety, low socioeconomic status, etc. In fact, when you compare PCS, not to healthy control, but rather other injuries (ie., sprained ankles), many of these scans show no differences. So the studies that show a positive correlation between PCS and white matter issues are mostly chalked up to poorly designed studies using improper control groups. So essentially what you read is misleading BS. Here is a video that will help you with your question on hitting the bag and making things worse: kzfaq.info/get/bejne/i5dja9Fyx5jHink.html

Hi hope you are well, I saw the free workshop that you gave and it has helped me a lot to plan my recovery, so I have a question, I have a very specific problem since i have pcs and that is that every time i make a quick movement with my head or have a small impact when walking, my head hurts for a second or two and then it goes away, that was my only symptom at the beginning and little by little as time went by it got worse and i acquired new symptoms every time it happened to me. So I would like to know if, as with the exercises for visual dizziness, it is possible to gradually expose the brain to movements and impacts? Why does the head hurt for a few seconds when there is a stimulus? can this be cured? thank you very much for your help.

PCS brainfog can be due to many things! I would recommend you look into the Concussion Fix program - google it and read some reviews. We are very good at helping people identify the drivers of this and helping them to get rid of it!

This is a great question! We actually don't know for sure in humans because we don't have the studies for it...BUT in animal studies (rats), their full cycle for recovery is 5 days and it seems that getting a concussion earlier in the cycle is not as bad as getting one in the middle. Put another way, getting a second concussion on day 1 after the first is not as bad as getting one 2 days after the first. But 2 days after the first was not as bad as getting another one 3 days after. Once the rats hit day 4 it was better than day 3, and day 5 was better than day 4. If we were to extrapolate this to humans then (which we should do with extreme caution), we would expect that getting a second concussion 1 week after the first may actually be worse than getting one 1 day after the first...

@@CompleteConcussions very interesting data, I look forward to researching this more, thank you!

There is no evidence of any structural damage after concussion...so no.

It's not a tolerance to electrical activity that is needed. It's a tolerance to the brain undergoing stretching. With enough stretching of the neuron, the chemical reaction will occur...the electrical storm is a byproduct of that. So you could not build tolerance to it....but it's also never been studied so I guess I shouldn't definitively say no :)

@@CompleteConcussions Then we need to make the neurons more elastic. Stretch the brain haha. Or make it resistant to strain maybe y increasing neuron thickness with more myeline?

@@konnor9577 No this won't work either because it's simply the opening of channels...watch this video series for a better understanding : kzfaq.info/get/bejne/h72GqqSm1rWWdIE.html

I would check out our concussion fix program! Google it and read some reviews and see what you think

@@CompleteConcussions Ok, thank you. Given my symptoms, do you think there’s hope for me to recover?

​@@IndialienJones yes! As long as you are willing to follow the program and do the work

Hi Patricia - which course?

@@CompleteConcussions 😳

@@CompleteConcussions I don’t even know. I been charge every month $ 50. But I’m not sure what to do. Thats how bad my head is.

@@CompleteConcussions ok. I think is the concussion fix

@@patriciahernandez5917 ok email nikki@concussiondoc.io and she will help you out! You should have gotten emails and instructions upon registration...Possibly ended up in junk folder?

whiplash happens at 4.5G

Holy shit man that's a long time you really need to find and go to a proper concussion clinic at that point. You should call and email a bunch of clinics to get some price quotes in your area.

@@iansmith3406 yea defenely
