You are linking issues that have no definitive connection. Inner ear crystals help with balance. They do not effect hearing or tinnitus. Tinnitus and hearing loss are not directly connected. You can get both from loud sounds but tinnitus is more of a nerve issues where hearing loss is usually a structural issue.

As you said, anxiety can be an issue. It can magnify many symptoms but is not usually a cause.

What symptoms are you struggling with ?

Please tell us about your concussion.

Well my symptoms which consisted of dizziness and a bit of a sore neck are now gone. The last time I was sure I suffered from a concussion is nearly a decade ago. Will the brain be more susceptible to a second concussion after having a first one? Regardless of time passed in-between say a decade? Will it be more vulnerable to injury for a lifetime? I thought we were build to be fairly resilient to fast head rotations due to the cerebrospinal fluid preventing collision with the inner skull. How fragile is the brain actually when it comes into contact with the skull? Does simply a light touch cause bruising on the brain or does it take a somewhat of a slam to cause injury?

Solved!

Not to bring this thread up again but just to end it with some good trustworthy news on this question, if anyone else are to wonder if this can happen, the answer is apparently a most definite no!

Today I've been talking with my local doctor about my earlier concussion many years ago, which also, since she declared it was a mild one I had, it can no longer affect my performance at all. According to her, rotating/shaking your head from side to side, rapidly or not, cannot under any circumstance cause a concussion unless it happened in a car crash with rear end collision. It requires a lot more force than a quick shaking, even if it is followed by a sudden change in rotation!

Just to confirm everything.
Good day to you all! :)

I doubt that you can get a concussion from just twisting your head too fast side to side, you might get concussion symptoms (such as dizziness/vertigo, nausea, neck pain, etc) especially if you're suffering from PCS.
For example, my otoloaryngologist (advanced ENT) had me shake my head up-down and side to side very quickly to look at how my eyes responded, and for a couple of days after that I felt worse.

As for the authority of any doctor on concussions - I've learned in the past two years that most doctors really have only a vague idea of what concussions are, and when it comes to PCS even most of the neurologists are clueless.
I've heard everything from "it's anxiety", "bad case of flu" to flat out telling me that what I'm experiencing is not possible after such a long time post concussion and I need to go see a shrink.

She's WRONG.

Not about not being able to get concussed from a routine shaking. That's correct - and you have nothing to worry about.

She is, however, GROSSLY overestimating the force required to cause a closed head injury.

There are DOCUMENTED cases (does your doc read journals? :rolleyes:) of headbangers sustaining concussions. Similarly, a lot of hockey players suffer DOCUMENTED concussions from checks that jerk their necks back and forth, without their head ever coming into contact with the ice, glass, etc...

Actually, if you look at the inside of the skull, you will see a very rough surface. There is not enough CSFluid to protect the brain from grating against this rough surface during a strong rotational force. The force one would exert during a simple fast right and left is unlikely to cause damage. The rotational acceleration would need to be faster than most neck muscles can generate. Repeatedly whipping the head back and forth is another issue. The cumulative effect of this repetition could cause trauma.

This might not be directly linked to my question, but generally speaking of the causes of concussions, since it's now confirmed I've, along with all of you, at least suffered a mTBI at some point in our lives, what is the aftermath?

I've heard that repetitive head trauma, concussive or subconcussive, can lead to CTE and/or eventually dementia due to the build up of tau protein in regions of the brain. Do you guys think that one single concussion develops abnormal levels of tau in the brain? Or do we have the ability to heal and prevent permanent damage if no further interruption of brain activity are to be present? I've just seen an NFL documentary where they seem to mention tau protein a lot, but according to them, it normally doesn't build up by one concussion. Long term repetitive hits are apparently required and some even have a genetic advantage. Anyways, will there be the slightest amount of abnormal levels of tau protein in the brain just because of one concussive impact during one's lifetime?

I've exasperated my symptoms from shaking a salad dressing too hard!

Minimac,

There are many reasons for tau protein to malfunction in the brain. Researchers are looking at those with excessive levels of these malfunctions and trying to find ways to reduce them. There is not as much opportunity to investigate the early/lesser accumulations of these defective tau proteins. Tau proteins are an important part of neurological function but it is when they become defective and get tangled that they are a problem.

Due to the prevalence of Alzheimer's Disease, the research is going strong with opes of finding ways to prevent these defects. Hopefully, the treatment will be affordable for the masses.

Getting worried about Tau proteins and CTE can be counter productive. The best solution is to use a good brain supplement regimen and stay mentally active. And, reduce stress in your life.
