Doctor have you looked into the studies behind recoil force from operating a firearm and its effects on the brain? I haven't operated one since before my injuries and would like to try it out again, but I'm afraid the intense but brief recoil right into the body through the shoulder might flare up my brain again.
I got a stupid question on what you said on 3:00. If concussion is a rapid increase in electrical activity that shuts the brain down, then would progressive overload of the current with transcranial magnetic stimulation, build up tolerance and increase the threshold at wich he brain shuts down and the athlete lose consciousness??
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 : th-cam.com/video/QWVwAuqO2DM/w-d-xo.html
Great vid and channel doc! Do those short headaches (or pain) right after hitting the head (like the below 1 minute ones) mean there is some degree of concussion? Or do they need to be sustained? Is it actually possible a large part of the population experiences undiagnosed concussion this way?
Great video! I have a question: I had a concussion about 6 weeks ago, since then I have slowly been recovering, although I am still symptomatic (headaches). I have been able to do steady-state cardio at 80% of my HR max for 3 weeks now. Am I ready to now start doing other types of exercise like weight lifting and rock climbing? Or should I wait with these kinds of anaerobic exercises until I am not symptomatic anymore? Hope you can give me some insights!
Hi. I bought your course on April and every month I been paying but honestly I never open one single video or class. Can you please tell me where to start or how to begin ?

Hey doc! Thanks for another excellent video. I was just wondering if you know how much less force it takes in order to cause a second/third concussion. I know after your first concussion you are more prone, but how much if a difference does this make?
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!
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!
What if another head injury occurs on the initial 20% decline? Would it cause the same extra depression you are referring to, that takes 90-120 days for the ATP to go back to a healthy range? For example, in the range of 1-5 days rather than the post concussion stage at 7-120+ days?
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...
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.
Hi! I have another question about the previous video of the little bumps, a few months ago I read that post-concussion syndrome causes structural changes in the brain such as atrophy and a decrease in white matter depending on the initial injury and the duration of the post-concussion syndrome and with the explanations that you have given I understood that small blows do not cause a concussion and that's why I dared to start exercising again but my doubts are: Can structural changes in the brain be reversed or at least improved? is it safe to hit the punching bag? The small impacts to the brain from those blows, even if they do not cause a concussion, can they worsen the symptoms that I already have? Thank you very much for your help, you have really given me a light of hope, God bless you.
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: th-cam.com/video/U138nAb2cZE/w-d-xo.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.
I’ve been post concussed for 3 years. I recently had an eye test with a neurologist. They told me a score from 10-20 indicates a concussion, and I scored 13.7. I’m having daily symptoms and it’s greatly impacted my quality of life. No doctors have been able to pinpoint the issue and help me. I suffer with dizziness, light headedness, tachycardia, head pressure and fullness, cognitive impairment, occasional motor impairment, episodes of anisocoria where one pupil will be large and the other small, etc. How can I work with you to get the help I desperately need?
hey doc! .. Do we lose lot of brain cells / neurons during mild concussions? cause we know , neurons dont regenerate, then how do people make full recover ?
Technically then if you don’t have a serious tbi then isn’t it not technically an “injury” since there is no actually “brain damage” or loss of brain cells? Could you clarify this?
You said that 70gs of force is needed for a concussion to occur. What if it is a whiplash injury where your body is hit. Is a different amount of force required then??
I have had at least 5 concussions through my lifetime. NOT ONCE was my head or brain ever addressed!! I developed Shingles years later in the most severe area of injury- left side of my head. I also have developed Fibromyalgia- a chronic, incurable condition that affects my nervous system Everyday. Until recently, they just said 'watch for enlarged pupils and dont go to sleep'. Im paying for neglect decades after these head and neck injuries.😢
Would slapping yourself with the palm of your hand as hard as you can on the top of your head cause a concussion? i.e. if you stiffened/braced your neck before impact, in your opinion can you still exceed 70G of force?
I’m a sport PT and I’m so glad to have found your channel
Great explanation as always!

Thank you so what is the difference between concussion and TBI? I have had 5 concussions and Brain Stem injury and TBI .
TBI = Traumatic Brain Injury - it comes in 3 different severities (mild, moderate, and severe). Concussion is the same thing as a mild TBI.
I got a stupid question on what you said on 3:00.
