Earliest stages of CTE impact Tony Dorsett
Former Pitt running back Tony Dorsett has been diagnosed with early signs of chronic traumatic encephalopathy (CTE), according to a report Wednesday from ESPN's "Outside the Lines."
Dorsett told "Outside the Lines" he has experienced emotional outbursts with his wife and two daughters, and sometimes has trouble remembering routine tasks and directions.
"It's painful, man, for my daughters to say they're scared of me," Dorsett told "Outside the Lines."
Dorsett even admitted he has contemplated suicide...
CTE is a degenerative brain disease caused by repeated head trauma and has been linked to depression and dementia.
Dorsett, 59, along with former NFL stars Joe DeLamielleure and Leonard Marshall, underwent evaluations at UCLA over the past three months. Brain scans and other evaluations indicated early signs of CTE in all three, researchers told ESPN.
The disease is caused by buildups of tau, a structural protein that can become dislodged during repetitive head trauma and affect brain cells controlling memory and emotions. Autopsies of former NFL players -- including former linebacker Junior Seau, who committed suicide in 2012 -- have shown such buildups.
Two weeks ago, Dorsett told "Outside the Lines" he was experiencing memory loss, depression and thoughts of suicide. These symptoms prompted him to seek testing for CTE.
CTE has no cure, but a January study of five former NFL players showed the first signs of the disease in living humans, which researchers told "Outside the Lines" was a significant step forward.
