Novel brain imaging technique explains <br>why concussions affect people differently

BRONX, NY -- Patients vary widely in their response to concussion, but scientists haven’t understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time.

The new technique could eventually help in assessing concussion patients, predicting which head injuries are likely to have long-lasting neurological consequences, and evaluating the effectiveness of treatments, according to lead author Michael L. Lipton, M.D., Ph.D., associate director of the Gruss Magnetic Resonance Research Center at Einstein and medical director of magnetic resonance imaging (MRI) services at Montefiore. The findings are published today in the online edition of Brain Imaging and Behavior.

The Centers for Disease Control and Prevention estimates that more than one million Americans sustain a concussion (also known as mild traumatic brain injury, or mTBI) each year. Concussions in adults result mainly from motor vehicle accidents or falls. At least 300,000 adults and children are affected by sports-related concussions each year. While most people recover from concussions with no lasting ill effects, as many as 30 percent suffer permanent impairment – undergoing a personality change or being unable to plan an event. A 2003 federal study called concussions “a serious public health problem” that costs the U.S. an estimated $80 billion a year.

Previous imaging studies found differences between the brains of people who have suffered concussions and normal individuals. But those studies couldn’t assess whether concussion victims differ from one another. “In fact, most researchers have assumed that all people with concussions have abnormalities in the same brainAir Jordan 89 Shoes
