- okay, I understand, thanks

-Well, now that I know that thinking too much is bad for me I have already started to try to tone it down and to "go more with the flow", so to speak.
With that being said, what do you mean with "more than simple stress to resolve "? And how likely do you think I am to recover from my condition and come back to a cognitive symptoms free phase?

'You have more than stress to resolve' relates to your need to be less obsessive with your thought processes. Your constant need to have every little issue addressed with a science based answer is counter to you moving forward.

Nobody can say what your recovery will be. Statistically, your best opportunity is to work with your current condition and stop fighting against it.

Today a pretty bad thing happened and now I'm in complete panic mode.
I had another fit of rage for a pretty serious family issue and moved by frustration I thrown a small toy leg which ended up hitting me in the head by rebound.
I was extremely angry because I was worried that a similar unlucky and very improbable accident might worsen my condition and compromise my recovery, and as a consequence I had probably the greates outburst if rage of my entire life.

Now I'm in a worse condition than before cognitive wise.

This is the toy leg, I specify that it hit me in the forehead/temple regione and that the impact was not hard enough to cause me any pain whatsoever.
It's possible that the blow was strong enough to cause problems to a weakened/concussioned/symptomatic brain?

No, there is not enough mass to that toy. I doubt it left more than a skin contusion.

Your concern should not be about the impact from the toy, it should be about your explosions. This condition has been called intermittent explosive disorder (IED). There are drugs that can help. You put yourself at risk of all kinds of injury with your outbursts. Even more is the risk of criminal behavior that can result in arrest and incarceration. Incarceration is very dangerous for somebody with PCS and IED.

These are the issues I am speaking about when I said 'You have more than stress to resolve.'

Your sense of a cognitive setback is far more likely to be a result of the rage and not a concussion.

You are right, I surely need to resolve that issue as fast as possible, but I don't want to use drugs out of fear of the side effects.
I will try to relax myself as much as I can and I will try to gradually control my reaction to stressing stimulus, it should not be so hard now that I have discovered the hard way that it can impact severely my cognitive condition.

Your concern about criminal beahviour and incarceration is excessive tough, I can assure you that I am not going to do anything like that (and I have never did anything like that in the past)

Do you mean like falling or accidentally hitting my head?
Or do you also mean something more subtle.

But isn't a skin contusion enough to trigger PCS symptoms to an already damaged/concussed brain?

A skin contusion is not enough to cause a relapse. The tenderness can cause an anxious focus that can magnify even very minor existing symptoms.

You anger puts yourself at risk of falling, busting bones or knuckles, angering somebody who may strike out at you, and more. The blood pressure spike could cause a stroke.

I don't know what law enforcement is like where you live but in the US, an outburst like you describe can cause an arrest and jail. A psychiatric assessment could also be ordered. Those can be very traumatic. I have a family member who has experience in this area. It was traumatic on him and the whole family.

I over-react to aggressive speech. I have been denied boarding an airplane flight because I reacted to a body pat down at the airport when the contact was a bit too intimate. I just get loud. I carry an explanation in my wallet to hand to the authority person when there is a likely stressful event. I KNOW THIS SUBJECT both personally and regarding my brother.

The side-effects of medication are far less that the risk of an explosion until you have time to learn the skills to lower your intensity.

How old are you? 19 or 20? Your brain's ability to get control over your anger will continue to be weak until your late 20s. Family issues are common triggers. PCS just makes those triggers worse. The cognitive struggle of confusion as you try to make sense of family events that are already difficult to make sense of is a recipe for disaster.

Now that I think about it, when I was at the pinnacle of my last outburst I experienced some intermittent pain in my chest for a few seconds.
It's possible that the worsening of my symtpoms is due to the excess of blood pressure?
In that case, should they come back to normal or could the damage be irreversible?
I also think that it is worth to note that, during the first month and half after my car accident, getting enraged usually improved by cognitive and thinking ability for a short amount of time (a couple of hours to a day roughly)

I'm sorry to hear about your traumatic experience.

I will try to get a grip and to get used to this kind of things/be less bothered by them.
I'm 21 by the way.

Stop asking these questions "should they come back to normal or could the damage be irreversible?"

Unless you have access to a time machine to go back in time, don't worry about what has happened. Look at every set back as recoverable. The only way to know otherwise it to see what happens over time.

You have too much life ahead to spend it looking backwards.

Adrenaline from an outburst can mess up your brain's chemistry for a while.

Can I ask why, in your opinion, in early June getting enraged actually lessened my symptoms and improved my thinking and cognitive skills?

Also, sorry if I may be annoying with those kind of questiones that are likely obvious in your eyes, but what do you mean with brain chemistry?

Here is a saying in science, "Correlation does not indicate causation."

You perceived improvement in cognitive function may have nothing to do with your anger explosion. Or, it could be that your brain hormones and such surged. Your combat sports may have conditioned your brain to release endorphins that can heighten mental function when you get stimulated by physical activity. Nobody can say.

By brain chemistry, I am referring to any of the chemical functions in the brain and how they cause toxic residue. Every metabolic function has its waste products. Repeated or high intensity stresses can overwhelm the brains toxin elimination system and cause brain dysfunction.

It is similar when one works out at the gym or goes for a hard run, the intense muscle use causes lactic acid to build up. The lactic acid clears from the muscles with just moderate muscle use.

The toxins in the brain only clear during a specific stage of sleep. If you are not experiencing enough slow wave sleep for the amount of waste produced, the brain can remain polluted. It struggles to use nutrients when it is congested with waste products. This is not a damaged condition.

Stress, physical or emotional stress, increases the production of these waste products that need to be cleared.
