Believe what you will about it. I've told you, if you keep searching, you'll drive yourself insane. It's not a good thing to believe it's 'Brain Damage.' It's mostly psychological. I was saying that if it were due to head trauma directly, your brain would not be putting emotion to your senses because of your brain's inability to process the information. You would probably need real damage to your optic nerve also, as well as in areas controlling sight, and sound, and everything else.

It's a defense mechanism you are more prone to with an injured brain, yes. I am not disagreeing with that. But, it is psychological. Concussion does not cause it, as it happens in normal healthy people with healthy, uninjured brains, who have not gone through PCS. You recieved overstimulation, so your brain protected itself.
