Gender may contribute to recovery time after concussion
Tuesday, May 6, 2014 · Posted by Radiological Society of North America
Each year, more than 17 million Americans suffer a mild traumatic brain injury (mTBI), more commonly known as a concussion, of which approximately 15 percent suffer persistent symptoms beyond three months.
Assessing outcomes and recovery time after concussion can be very subjective. Typically, physicians must rely on patient cooperation to assess injury severity.
Penn Researchers Model a Key Breaking Point Involved in Traumatic Brain Injury
Wednesday, March 5, 2014 · Posted by The University of Pennsylvania
Their recent findings shed new light on the mechanical properties of a critical brain protein and its role in the elasticity of axons, the long, tendril-like part of brain cells. This protein, known as tau, helps explain the apparent contradiction this elasticity presents. If axons are so stretchy, why do they break under the strain of a traumatic brain injury?
On-field Blood Test Can Diagnose Sports Concussions
Thursday, January 9, 2014 · Posted by University of Rochester
A brain protein, S100B, which may soon be detected by a simple finger-stick blood test, accurately distinguishes a sports-related concussion from sports exertion, according to a study of college athletes in Rochester, N.Y., and Munich, Germany.
Study links nonconcussion head impacts in contact sports to brain changes and lower test scores
Wednesday, December 11, 2013 · Posted by Indiana University
Using a form of magnetic resonance imaging, or MRI, researchers at the Indiana University School of Medicine and the Geisel School of Medicine at Dartmouth College found significant differences in brain white matter of varsity football and hockey players compared with a group of noncontact-sport athletes following one season of competition.
Dietary amino acids improve sleep problems in mice with traumatic brain injury

Nearly 2 million people a year in the United States suffer a traumatic brain injury, including concussion, which is considered a mild traumatic brain injury. Sleep disturbances are common in those with TBI; some studies show up to 72 percent of TBI patients — including those who’ve suffered concussions — have sleep problems.
Study shows first link between altitude and concussion
Monday, December 9, 2013 · Posted by University of Colorado, Denver
A new study shows that high school athletes playing at higher altitudes suffer fewer concussions than those closer to sea-level, a phenomenon attributed to physiological changes in the brain causing it to fit more tightly in the skull.
Concussion secrets unveiled in mice and people

In this study, researchers also discovered that certain molecules, when applied directly to the mouse skull, can bypass the brain’s protective barriers and enter the brain. The findings suggested that, in the mouse trauma model, one of those molecules may reduce effects of brain injury.
Brain still injured from concussion after symptoms fade

After a mild concussion, special brain scans show evidence of brain abnormalities four months later, when symptoms from the concussion have mostly dissipated.
From football to flies: lessons about traumatic brain injury
Monday, October 14, 2013 · Posted by University of Wisconsin-Madison
“These exciting findings that we can study traumatic brain injury — a disorder of growing concern for athletes, the military, and parents — in the elegantly simple model of fruit flies is sure to interest those researchers and companies looking to address this concern,” says Jennifer Gottwald, WARF licensing manager. “The use of this model can accelerate the work of the medical research community in finding treatments and therapies to help patients.”
Football’s Concussion Problem, in 3 Terrifying Pictures
Tuesday, October 8, 2013 · Posted by Mother Jones
While the symptoms of a concussion—dizziness, vomiting, memory loss—can be felt immediately, the long-term impacts of repeated brain trauma have been harder to study. Research points to chronic traumatic encephalopathy, or CTE, as one of the major outcomes. CTE is caused by a buildup of tau, a protein that strangles brain cells and degenerates brain tissue, which is caused by repetitive brain trauma like the hits football players endure.
