The study was done with the mouse model as the human analog, however its results could lead researchers down the path of what most believe about multiple insults to the brain;
We did it in mice. We gave them one mild concussion, so mild that they had no problems with learning or memory afterwards and then did it over and over and over again,” said Meehan, the study’s first author.
The mice were then tested for learning and memory, using what’s called a Morris water maze.
“Under the surface of the water is a hidden platform. And every time the mice find that platform, we reward them,” said Meehan. “The mice that are uninjured, have not been concussed, find that platform within five seconds after they do it several times. But mice that are injured take 20 to 25 seconds.”
And with each concussion, Meehan said it just got worse.
“Once they’ve had three concussions, or five, or 10, they develop profound deficits in their ability to learn and in their memory. And of course, mice don’t use steroids, and they don’t abuse drugs and alcohol,” said Meehan
The study appears in Neurosurgery and highlights not only the compounding effects of multiple traumas but takes out the other “factors” some seem to be grasping at for a reason as to why the brain is suffering. While we are looking at the text, it seems Continue reading
Irv Muchnick has been through a lot in digging up information about head trauma, steroids, and other issues related to what he terms “the cocktail of death” in pro wrestling. However, the seemingly endless roadblocks has not stopped him from great fact-finding in an effort to make the issue of head injuries, in particular CTE transparent.
Muchnick has an exclusive find as posted today on his blog;
In his latest letter to me last year threatening to sue me for my reporting, World Wrestling Entertainment lawyer Jerry McDevitt pointed out that Dr. Bennet Omalu’s study of dead wrestler Chris Benoit’s brain was not published in a peer-reviewed scientific journal until 2010, and then only in “an obscure nursing journal.” See “New Threats From WWE Lawyer Jerry McDevitt,” December 17, 2010, http://wrestlingbabylon.wordpress.com/2010/12/17/new-threats-from-wwe-lawyer-jerry-mcdevitt/.
After wading through all difficulties he has found and praised Neurosurgery for their restructuring including changing editor-in-chief;
However, I understand that Oyesiku was named to replace Dr. Michael Apuzzo as editor of Neurosurgery with a mandate that included reversing the journal’s perception as a de facto NFL house organ for academic articles answering loaded questions, which in turn served the commercial interests of the league and its contract doctors and business partners. Apuzzo, a consultant for the New York Giants, had overseen the publication of a decade’s worth of controversial studies on aspects of brain trauma in sports – including the 2006 article on the Riddell helmet manufacturer’s new design, which was co-authored by the company’s chief engineer and by Pittsburgh Steelers team neurologist and imPACT software entrepreneur Dr. Joseph Maroon, and is now the focus of a Federal Trade Commission probe of Riddell’s allegedly misleading promotional claims.
Apparently Dr. Bennet Omalu’s third study of a professional football player (Mike Webster and Terry Long being the first two) about Andre Waters Continue reading
