In a new study researchers have come up with a report saying most of the deceased NFL players have been tested positive for brain disease. A total of 97 such players were studied. These players had donated their brains after their death as it was believed repeated head trauma and concussions were linked to brain disease.
Out of these 91 brains researchers have found 87 of those to have tested positive for brain disease. These players had chronic traumatic encephalopathy (CTE). However, it is not very clear why all the NFL players didn’t develop the disease.
The data was released by the US Department of Veterans Affairs and Boston University and details of it was published online on Concussion Legacy Foundation website. It writes 95.6 percent of deceased NFL players have been tested positive for the CTE disease.
Dr Ann McKee, chief of neuropathology at the VA Boston Healthcare System, said the CTE is a real disease and although it was believed one of the likely causes of it is concussions, but new evidence says minor head trauma occurring regularly in the game may pose greater risk compared to the occasional violent collision.
In the study the offensive or defensive linemen were almost half the number as they are subject to violent collisions.
The issue first came to notice after ‘Frontline’ documentary TV program reported it.
