Degenerative brain disease affects most football players 

Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time, whether due to normal bodily wear or lifestyle choices such as exercise or eating habits.Degenerative diseases are often contrasted with infectious diseases. A progressive, degenerative brain disease known as chronic traumatic encephalopathy (CTE) was found in 99 %of former National Football League (NFL) players whose brains were donated for research after their deaths, a study said.

According to a Study:

• The study, published in the Journal of the American Medical Association (JAMA), on Tuesday.
• It said CTE may be more common among football players than previously thought.
• Jesse Mez, a Boston University School of Medicine (MED) assistant professor of neurology and lead author of the study.
• He said,the data suggest that there is very likely a relationship between exposure to football and risk of developing the disease.
• Mez and colleagues examined the donated brains of 202 former football players for evidence of CTE.
• In addition,which has linked to repeated blows to the head.

Researchers:

• Researchers believe CTE is caused by the buildup of an abnormal form of a protein called tau in the brain.
• It can lead to brain cell deaths and a variety of clinical symptoms, including memory loss.
• In addition, confusion, impaired judgment, depression, suicidality and eventually progressive dementia.
• Of the 202 brains studied, the group diagnosed 177 with CTE.
• The study has several limitations including that it is a skewed sample based on a brain donation programme.
• Because public awareness of a possible link between repetitive head trauma.
• Furthermore,CTE may have motivated players.
• Their families with symptoms and signs of brain injury to participate in this research.
• As a result, the researchers urged caution in interpreting the high frequency of CTE in this study.
• Stressing that estimates of how prevalent CTE may be cannot be concluded or implied.
• They noted that the study,the largest and most methodologically rigorous CTE case series ever published.
• Offers important information and direction for further research.
