Caregiver, you say... "the problem with such an injury is not "shearing axons"
Can you provide a bit of info on why "shearing axons" is not a problem in such injury?
as far as swelling or bleed, I think I am less concerned with it since I would think I would have felt at least a slight discomfort of some kind if that was occurring, perhaps a headache.
Thanks!!
Hi
Welcome to the MedHelp forum!
I agree with Caregiver that it is a very difficult question to answer. The force that can cause brain damage or damage the nerves cannot be quantified. Some people get symptoms by what would be considered mild injury by another person. Also people respond differently to concussion. A person may just have dizziness, or he may have loss of memory. Some become depressed and on other extreme some develop schizophrenia. However there are a considerable number who do not develop any symptoms.
You just need to wait and watch.
Take care!
Because of your loss of consciousness, you should had both an MRI and an MRA.
Clearly you have asked a "how many angels are on the head of a pin" question.
That being said, the problem with such an injury is not "shearing axons, but involves both a potential bleed (slow or fast - which should have meant a scan), and swelling, which causes the impingement of microcirculation providing both oxygen and nutrients to brain cells.
Unresolved within a limited window, such swelling can lead to the death of brain cells and parts of the brain such as the pituitary and hypothalamus. The time to death of the cells is referred to as the warm ischemic time.
There is no evidence whatsoever that a concussion will make anyone smarter.
There may or may not be a degradtion in your cognition, memory and reasoning. The human brain is very resilient.
