In previous year a big concern has been expressed when dealing with the outcome of head injuries and brain damage within in the sports arenas. Sports such as football, soccer, swimming, baseball, basketball, and rugby have faced major concerns when involving the brain which affects if emotionally, physically, and psychologically. The sports have produced such problem as concussions, brain damage, over competiveness and depression.
The sport of football has produced theIn 1995 more than 61% of former NFL players had concussions during their playing days, and most of them said they were not sidelined after their injuries, according to a study in 1996. The report was based on a survey of 1,094 former players, ages 27 to 86, conducted in 1995-96 by the NFL Players Association. Head injuries are relatively common in football, accounting for up to 22% of all injuries in the sport.
A fraction of these injuries are concussions, which are states of neural dysfunction resulting from head trauma in which there is the possibility of dizziness, headache, confusion, visual disturbance, amnesia, loss of consciousness, drowsiness, nausea, and/or vomiting. Slurred speech, disorientation, lack of coordination, inappropriate emotions, and auditory abnormalities may also be observed as part of the concussive state. Concussions in football players have been linked with drop-offs in their cognitive functioning.
For example, in a study carried out at Erasmus University in Rotterdam, the Netherlands, in which 84 active professional players from several premier-league football clubs were evaluated, the frequency of football-related concussions was linked with poorer results on tests measuring sustained attention and visuoperceptual processing. In addition, a classic study carried out with 69 active football players and 37 former members of the Norwegian national football team determined that 30% of the former players complained of permanent problems such as headache, dizziness, irritability, neck pain, and impaired memory.
In addition, 35% of the active players and 32% of the former players displayed abnormal EEGs, compared with about 12% of matched control individuals. When the former players were subjected to cerebral computed tomography (CT) and a neuropsychological examination, a full one-third of the athletes were found to have central cerebral atrophy (wasting of the central region of the brain), and 81% displayed at least some signs of neuropsychological impairment. Many of these problems were said to be linked to concussions suffered by the players during their football careers. most concussions within the sport.
