Blows To The Head Lead To Vision Loss

Blows To The Head Lead To Vision Loss.
As more enquire focuses on the mar concussions can cause, scientists now report that even mild blows to the talent might affect memory and thinking. In this latest study, special helmets were used on football and ice hockey players during their seasons of play. None of the players were diagnosed with a concussion during the meditate on period, but the remarkable helmets recorded key data whenever the players received milder blows to the head. "The accelerometers in the helmets allowed us to include and quantify the intensity and frequency of impacts," said read author Dr Tom McAllister.

And "We thought it might fruit in some interesting insights". The researchers found that the extent of change in the brain's white matter was greater in those who performed worse than expected on tests of reminiscence and learning. White matter transports messages between sundry parts of the brain. "This suggests that concussion is not the only thing we need to pay prominence to," said McAllister, chairman of the department of psychiatry at the Indiana University School of Medicine.

So "These athletes didn't have a concussion diagnosis in the year we calculated them and there is a subsample of them who are perhaps more defenceless to impact. We need to learn more about how long these changes last and whether the changes are permanent". The over was published online Dec 11, 2003 in the journal Neurology. Concussions are submissive traumatic brain injuries that occur from a sudden blow to the head or body.
