Concussions In Sport
Concussions, a type of mild traumatic brain injury, are a frequent concern for those playing sports, from children and teenagers to professional athletes. Repeated concussions are a known cause of various neurological disorders, most notably chronic traumatic encephalopathy (CTE), which in professional athletes has led to premature retirement, erratic behavior and even suicide. A sports-related concussion is currently defined as a "complex pathophysiological process affecting the brain, induced by biomechanical forces". Because concussions cannot be seen on X-rays or CT scans, attempts to prevent concussions have been difficult. The dangers of repeated concussions have long been known for boxing, boxers and wrestling, wrestlers; a form of CTE common in these two sports, dementia pugilistica (DP), was first described in 1928. An awareness of the risks of concussions in other sports began to grow in the 1990s, and especially in the mid-2000s, in both the medical and the professiona ...

Concussion
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. Symptoms may include loss of consciousness (LOC); memory loss; headaches; difficulty with thinking, concentration, or balance; nausea; blurred vision; sleep disturbances; and mood changes. Any of these symptoms may begin immediately, or appear days after the injury. Concussion should be suspected if a person indirectly or directly hits their head and experiences any of the symptoms of concussion. It is not unusual for symptoms to last 2 weeks in adults and 4 weeks in children. Fewer than 10% of sports-related concussions among children are associated with loss of consciousness. Common causes include motor vehicle collisions, falls, sports injuries, and bicycle accidents. Risk factors include drinking alcohol and a prior history of concussion. The mechanism of injury involves either a direct blow to the head or forces elsewhere on the body that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

This set of symptoms occurs in a wide range of conditions and may have many causes, including neurodegenerative conditions, drugs, toxins, metabolic diseases, and neurological conditions other than PD. Signs and symptoms Parkinsonism is a clinical syndrome characterized by the four motor symptoms found in Parkinson's disease: tremor, bradykinesia (slowed movements), rigidity, and postural instability.

Asymptomatic
In medicine, any disease is classified asymptomatic if a patient tests as carrier for a disease or infection but experiences no symptoms. Whenever a medical condition fails to show noticeable symptoms after a diagnosis it might be considered asymptomatic. Infections of this kind are usually called subclinical infections. Diseases such as mental illnesses or psychosomatic conditions are considered subclinical if they present some individual symptoms but not all those normally required for a clinical diagnosis. The term clinically silent is also found. Producing only a few, mild symptoms, disease is paucisymptomatic. Symptoms appearing later, after an asymptomatic incubation period, mean a pre-symptomatic period has existed. Importance Knowing that a condition is asymptomatic is important because: * It may develop symptoms later and only then require treatment. * It may resolve itself or become benign. * It may be contagious, and the contribution of asymptomatic and pre-symptomat ...

Helmet-to-helmet Collision
Helmet-to-helmet collisions are occurrences in gridiron football when two players' football helmets make head-to-head contact with a high degree of force. Intentionally causing a helmet-to-helmet collision is a penalty in most football leagues, including many high school leagues. Despite its long association with American football, this type of contact is now considered to be dangerous play by league authorities due to the potential of causing serious injury. Major football leagues, such as the National Football League (NFL), Canadian Football League (CFL), and NCAA, have taken a tougher stance on helmet-to-helmet collisions after the US Congress launched an investigation into the effects repeated concussions have on football players and the new discoveries of chronic traumatic encephalopathy (CTE). Other possible injuries include head traumas, spinal cord injuries, and even death. Helmet manufacturers are constantly improving their designs in order to best protect their users ag ...

The NFLPA, which has headquarters in Washington, D.C., is led by president J. C. Tretter and executive director DeMaurice Smith. Founded in 1956, the NFLPA is the second-oldest labor union of the four major professional sports leagues; it was established to provide players with formal representation to negotiate compensation and the terms of a collective bargaining agreement (CBA).

In the early years of the NFL, contractual negotiations took place between individual players, their agents, and management; team owners were reluctant to engage in collective bargaining. A series of strikes and lockouts have occurred throughout the union's existence largely due to monetary and benefit disputes between the players and the owners. League rules that punished playe ...

University Of North Carolina At Chapel Hill
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school.
