96% of ex-NFL players had brain disease

Hitting your head against hard substaance can have an adverse effect o
n the brain. It can lead to CTE which is a progressive
degenerative brain disease
found in some athletes with
repetitive brain trauma.

According to CNN—Eighty-seven of 91 former NFL players who donated
their brains to science after
death tested positive for a brain
disease that is believed to be
linked with repeated head
trauma and concussions,
researchers said.
The former players were found
to have had chronic traumatic
encephalopathy, known as CTE,
according to the U.S. Department
of Veterans Affairs and Boston
University.
It's not clear why some players
develop the disease and others
don't.
The study results don't
necessarily mean that 96% of all
NFL players are at risk for CTE,
said Dr. Robert Cantu. The brains
came from players who, while
they were alive, had concerns
about CTE. His group began its
work in 2008.
The data was published on the
website for the Concussion
Legacy Foundation, which Cantu
co-founded, and first reported
Friday by the documentary TV
program "Frontline."

It is advisable to choose our kind of athlete or sport wisely either
for recreation or as a career.
