Brain degenerative diseases are characterized as the most frequent perpetrators of suicide and mental illness professional athletes which may be rooted in the time when they were engaged in sports as a child and received blow during the primary and secondary school, say experts .
Theory says that many people who are not professional athletes, but have engaged in any sport as children, are at risk of developing chronic traumatic encephalopathy (CTE), reports ABC News.
"We do not know at what age has started to develop the disease in any of these cases. We believe that all starts at a very young age of childhood," said Chris Nowinski, director of the Boston University Center.
The recent discussion in CTE-opened after successful former baseball player Ryan Freel, who committed suicide at the age of 36 years, was diagnosed CTE disease, which was not connected so far with baseball players, Koha.net broadcasts. Until now, CTE usually plugged tougher sports such as football, ice hockey and boxing.
Nowinski cut off and studied the brains of more than 180 athletes. This study has not been completed yet and it is not known how many subjects had CTE.
Nowinski noted that Freel had a well-documented history of blows to the head since childhood, when he was playing football.
Severe blows and blows to the head start in the early years in any sport career when kids join sports teams and youth leagues. According to a recent report by the Institute of Medicine of the United States, more than 250,000 athletes under the age of 19 are treated in medical institutions due to strikes and other brain injuries in 2009. Athletes from colleges are twice more risk of stroke compared to high school athletes.
Nowinski said the new brain had studied and who had CTE belonged to a 17-year-old sportsman, reports Koha.net. However, degenerative process began at a young age. CTE persons who have problems with memory, they are confused, have trouble with self-control, are aggressive, have depression and in some cases suffering from progressive dementia.
Symptoms may occur some months, years or decades after the brain injury.
