New research has confirmed that Mild Traumatic Brain Injury causes persistent neurological and cognitive problems in patients, taking an emotional and financial toll on society.
Dr. Douglas Smith of Center for Brain Injury and Repair and professor of Neurosurgery at the University of Pennsylvania School of Medicine, recently presented his findings on MTBI, also called concussions, at the 2010 meeting of the American Association for the Advancement of Science in San Diego. http://www.sciencedaily.com/releases/2010/02/100219204409.htm
More than 1 million people each year suffer from MTBI, but too many physicians and medical providers don’t consider it a serious injury. http://www.ivanhoe.com/channels/p_channelstory.cfm?storyid=23565
In Smith’s study, he has used advanced neuroimaging techniques to secure data from humans and animals two to four days after they sustained their brain injury. Researchers found that there were changes in the white matter of the brain, and that protein markers linked to brain pathology also turned up with these subjects.
Smith found that the stretching and unhooking of nerve-cell axoms after a MTBI causes problems in the sodium channels found on neurons. While this issue has been discussed for years, including on our webpages, it is stil always good to hear new findings to confirm what we have been saying all along.
