This report was brought to my attention by Matt Chaney, it details a study of former NFL’ers;
Unusual activity in the frontal lobe, observed in former National Football League (NFL) players as they carried out a cognitive test, matched records for heavy blows they had received to the head while on the field.
“The NFL alumni showed some of the most pronounced abnormalities in brain activity that I have ever seen,” said lead author Adam Hampshire, a neuroscientist at Imperial College London.
“(The) level of brain abnormality correlates strongly with the measure of head impacts of great enough severity to warrant being taken out of play.
“It is highly likely that damage caused by blows to the head accumulate towards an executive impairment in later life.”
NFL games have come under growing scrutiny for what critics say is a dangerous rate of concussions after hard blows to the head.
Some have drawn links between the on-field physical traumas and later neurological problems such as Alzheimer’s or Parkinson’s, which in turn have been blamed for depression and suicide.
The new study does not find evidence of disease, but highlights brain areas that may have been affected by repeated, severe impacts. And it says standard tests do not pick up this subtle damage.
This has been reported on by several “non-sports” media outlets but I cannot find it on a link to a popular sports news source, if you have let us know in the comments… This link is from ABC, Australia…
