Constant head blows in American football have been shown to be the cause of chronic traumatic encephalopathy (CTE)
Researchers: 96% of ex-NFL players had brain disease
Constant head blows in American football have been shown to be the cause of chronic traumatic encephalopathy (CTE), which has led to debilitating symptoms after retirement, including but not limited to memory loss, depression, mood swings, behavior changes and suicide.
When you look at the long list of NFL players whom have been diagnosed with CTE before and/or after their death, you will find players such as Jovan Belcher, Forrest Blue, Bill Bryant, Ronnie Caveness and so many more valuable players. Reported symptoms of CTE continues to grow each year in not just the NFL but in all branches of Football starting with toddlers.
According to the Boston University CTE Center, CTE is a brain degenerative disease found in athletes, military veterans, and others with history of repetitive brain trauma. Although CTE is highly controversial and misunderstood; it is believed that a protein called Tau forms clumps that slowly spread throughout the brain, killing brain cells.
There are also theorized research that suggest early CTE might result from damaged blood vessels within the brain. That could trigger brain inflammation and, eventually, the development of proteins such and tau believed to play a key role in CTE. This hypothesis was tested on adult mice; the researchers state that their brains possess similar attributes to that of human brains. Using a special device, the mice were given precise impacts that would lead to mild brain traumas similar to what an athlete would suffer in contact sports. The mice, whose brains were scanned using a specialized MRI, immediately showed changes to the electrical functions of their brains.
