does this have to do with the healing power of some bodies over others? I bruise easily but heal VERY fast. Genetics - OK - I can certainly agree that genetics may play a part in healing from a concussion - is that what you're saying? |
I think that's the mystery that continues to confound even the most advanced technology medicine provides today. Concussions aren't anything like other injuries, it isn't like your brain is bruised or broken the same way you'd break or bruise another part of your body--the brain gets rattled and it's more like the software, rather than the hardware, gets scrambled up and malfunctions. It looks like there may be some people who (at a genetic level) are able to "reboot" quicker than others. I hope that makes sense. |
I think I can understand that. Different people have different healing powers. And that is genetics. In so far as medical science knows, once the nerves are severed in the skull - we do not know how to repair them. But it may be that certain people can withstand a blow to the head and not have severe nerve damage. I keep thinking of the saying "hard-headed". I think that saying may be more than just an idiom. As I have said before, closed head injuries are still a mystery to medical science. The only way doctors or pathologists can determine a bruise on the brain or nerve damage is either through an autopsy or brain scan. And the brain scans do not determine how MUCH of the brain is damaged.
What the medical field relys on for concussion is the 'victim's' ability to function via standard tests (visual, audio, muscular, comprehension). but those tests may be fine for an average citizen. I don't think these tests are geared towards a finely tuned athlete. Able to walk does not mean able to skate - and certainly able to skate in the highly skilled environment of professional hockey.
OK - I may be blowing smoke here. But I honestly don't think so.

Going on my 1st year genetics class (which I didn't do well in  ), I think it basically says what both you and Av are saying. Some people (25% of the population acc. to the abstract/summary) possess a certain gene sequence (allele) that correlates with longer lasting symptoms after a head injury. However, those symptoms can't be classified into a particular existing pathology. I didn't bother to read the article because I wouldn't understand most of it, so I don't know if that it's due to a more severe injury or a lower ability to heal. I suppose it could be either pending on whether the allele influences the development of brain structure or if it influences whatever mechanisms are involved in healing.
