Hypo,

Welcome to NeuroTalk.

There is no value to trying to determine if any of your past injuries or events were a concussion. Every concussion is different and every brain's response to a concussion is different. Some can get knocked out and never experience any problems.

If these three events were the only times you may have experienced a concussion, you have survived to adulthood quite well. Your biggest concern should be avoiding anxiety issues. The toxins that anxiety can leave in your brain can cause trouble.

Yes, there is a risk but most who have problems have experienced multiple concussions plus a lifetime of lesser impacts. Even then, the researchers are confounded why some develop problems and some do not.

The only thing you can do at this point is take care of your brain. Reduce/avoid stressors to your brain like getting drunk or using recreational chemicals. Avoid risky activities like heading a soccer ball or other contact sports that can result in concussions. Seriously consider brain health nutrition. There is a brain health vitamin regimen in the Vitamins sticky at the top. B's, D-3, and the anti-oxidants and Omega 3 fish oil would all be worthwhile.

Try to consider this simple question. Even if you did suffer 3 concussions and they did leave you with some level of brain injury, how would that change your life ?
