2th, thanks for thinking of me, lo these many days. That is a well done presentation. I think the thing it minimizes is that brains are different (I know, it does state that...once), but it doesn't appear that we know why the same (relative) impacts have such different outcomes. Thousands of soccer players head the ball in exactly the same way, over and over, yet some seem to be affected and others less so, if at all. Football players, with their scientifically designed helmets, seem somewhat protected, although we know it's what happens inside the skull, that helmets can't do much about.Bears2thDoc said:

Here's an anecdote of mine. At a hs baseball practice, I was 20' past first, having run out a grounder, when I was beaned in the back of the head and knocked cold. I don't know how long I was out, but I woke up on my back with the coaches and players standing around me. The coach told me to go sit down, which I did. Then, I was ignored by one and all for at least an hour. Seeing no help forthcoming, I stumbled to the bus stop, rode home and promptly vomited. I was rushed to the hospital where I stayed overnight and then pronounced good to go.82gradDLSdad said:
One anecdotal piece of evidence on our differences: I hit the guy teaching me how to box on the top, front of his head and he didn't blink; he hit me on the top, front of my head and I saw stars. I was 8" taller and 50 lbs heavier than the guy. Thank God I only played one year of football and only worked out on the heavy bag after that sparring session.

Researchers may be closing in on a way to check athletes while they're alive for signs of a degenerative brain disease that's been linked to frequent head blows. Experimental scans found higher levels of an abnormal protein tied to the disease in a study of former National Football League players who were having mood and thinking problems.
It's the first time a major study has tested these scans for detecting chronic traumatic encephalopathy, or CTE, which is only diagnosed now after death, with brain autopsies.
Doctors are searching for a way to tell when players, veterans or others with concussions or other head injuries are at risk for permanent damage. It's too soon to know if the scans will enable that so far they only show that these athletes are different as a group; they can't be used to say a particular player does or does not have CTE.
"We're not there yet," said Boston University neuroscientist Robert Stern. "It is not ready to be used for individual diagnosis in the clinic."
He led the study, published Wednesday by the New England Journal of Medicine.
"It's an encouraging advance. It looks like they have detected CTE in living players," said Dr. Gil Rabinovici, a neurologist and imaging expert at the University of California, San Francisco, who is doing other research using the scans.
"It's hugely important to be able to detect the disease in living people" to know how common it is and to research treatments, he said.
Similar to the baseline testing Cal athletes take.TandemBear said:
I may have already posted this, but for all you parents of young(er) kids...
Concussion baseline testing is available for children. They are conducted BEFORE any injury occurs or is suspected. These tests will help diagnose, treat and determine recovery if a concussion is sustained or suspected.
A girl on my daughter's soccer team suffered a concussion. Her mother learned, only after the fact, that pre-injury testing is available for kids. She really wishes she had known beforehand. Children's Hospital/UCSF Benioff Oakland offers this service for $40. Well worth the expense if the worst comes to pass.

I suppose the term, "shaken baby syndrome" is one you aren't familiar with.TandemBear said:
I'm going to reserve judgement on the statement that kids are really susceptible to injury caused by sub-concussive impacts. Humans have survived millions of years of evolution, with children sustaining all sorts of impacts without helmets or other protective gear. I find it hard to believe that suddenly our kids are these beings will eggshell skulls containing brains that are prone to injury after the slightest impact. You think parents never dropped kids? Kids never fell down? Things didn't hit them in the head in the past? Kids, by their nature, are always falling down, playing rough, taking risks and getting injured. That's what kids do!
I don't think "evolution" involved kids (or adults) incurring so many blows to the head or blows that cause the brain to collide with bone as are incurred over a football career. Nor do I think that kids, by their nature, incur so many blows.

The brain sits in fluid inside the armor of a skull, and even nonconcussive whacks can result in brain colliding with bone. A couple of hard hits can come to resemble a concussion. The average football player, according to Cantu, takes 600 to 800 hits in high school and 800 to 1,000 in college.
