Risk of concussion History of concussion: For high school athletes, a history of concussion more than doubled the risk that an athlete would suffer another concussion, with the association greatest in football and amateur rugby; and College football players with a history of 3 or more concussions are at 3-times-higher risk of repeat concussion.
Concussions are an incredibly common injury, affecting millions of Americans each year. Despite their worrying regularity, the long-term impacts and health ramifications of a concussion are still not entirely understood. Breaking research shows changes in white matter function 6 months after a head injury.
In short, a concussion is a brain injury that changes the way the brain functions. Concussions can happen in a myriad of ways, but contact sports are most commonly to blame.
The primary effects of a concussion include thinking cognitive problems, headachesand issues with balance; these are normally temporary problems. However, as researchers investigate this type of injury more thoroughly, using new brain imaging techniques, longer-term changes are being brought to light.
The long-term effects of concussion The most recent study to investigate the longer-term effects of concussion will be presented at the Sports Concussion Conference in Chicago, IL, July The conference is being hosted by the American Academy of Neurology, who are leaders in the field of sports-related concussions.
The study was headed up by Melissa Lancaster, Ph. Each participant received an MRI scan, their concussion symptoms were rated, and other parameters - such as cognitive deficits, balance problems, and issues with memory - were also recorded.
The scans and assessments were carried out after 24 hours, 6 days, and 6 months following the trauma. The results of these assessments were compared with 18 matched athletes who had not sustained a head injury.
The participants were given advanced brain scans - diffusion tensor imaging and diffusion kurtosis tensor imaging. These exams checked for short- and long-term changes in the functioning of the brain's white matter.
White matter changes White matter is so called because, as the name suggests, it is lighter in color than the gray matter that surrounds it.
Initially considered to be a relatively passive and unimportant part of the brain, white matter is now known to play a vital role in brain function and learning. Gray matter can be thought of as the processing and cognition center, while white matter acts as a relay station, communicating between different areas.
Its tracts and projections make up the bulk of the deep regions of the brain. In fact, white matter makes up around 60 percent of the brain's volume. Tensor imaging is a relatively new imaging technique; it measures how water moves diffuses through brain tissue and charts changes in the way that information passes between regions of the brain through white matter tracts.
White matter and concussion The scans showed that the concussed athletes had a reduction in water diffusion throughout the white matter at the hour and 6-day markers, compared with athletes who had not sustained a head injury. These alterations in the brain's microstructure persisted 6 months later.
The athletes who had experienced the most severe symptoms following the concussion were the most likely to display white matter anomalies at the 6-month mark.
Despite the persistent changes seen in the scans in the 6-month tests, there were no differences between the injured and non-injured athletes' self-reported concussion symptoms, balance, or cognition.
These findings have important implications for managing concussions and determining recovery in athletes who have experienced a sports-related concussion. But, due to the prevalent nature of head injuries in sports, follow-up research is likely to come hot on this study's heels.

Sports collision sports (football, ice hockey, rugby) have the highest rates of concussion in men at all levels of competition;. Football is a rough sport, and despite the helmets, pads, braces, and supports, injuries are a common part of the game. The combination of the size of the players, speed of play, and physical nature of the game makes football injuries quite common.
One consequence that football players face everyday is the risk of getting a concussion. Concussions are a major problem in the sport of football.
Concussions are “a type of traumatic brain injury, or TBI, caused by a bump, blow, or jolt to the head that can change the way your brain normally works”(CDC).
Essay Injuries in Football Injuries in American football and how to reduce Coll Thesis Statement Injuries in American football, can some of them be prevented? With the increase in injuries in football coaches are looking for better ways to try and prevent unnecessary injuries.
Most sports-related head injuries, such as concussions — which temporarily interfere with the way the brain works — are mild and allow for complete recovery. However, concussion in children can pose serious health risks.
then resume the activity for shorter periods and gradually work up to pre-concussion levels as symptoms improve.
Concussions and College Football Head injuries in the world of sports and athletics are not typically unheard of but in actuality they are extremely common.
Depending on the type of sport played, the rates of head injuries vary and are higher in some sports than in others.
