Signs of CTE were detected in the Hall of Fame rusher after he underwent brain scans and clinical evaluations at the University of California, Los Angeles, in 2013. 

CTE is a degenerative condition that is characterized by dementia, aggression and depression. 

Dorsett talked about how the condition has been affecting his life during an interview yesterday with Dallas radio station 1310 The Ticket, according to the Dallas Morning News.

He said: 'I'm in a battle, obviously. 

'I got diagnosed with CTE and it's very frustrating at times for me. 

'I've got a good team of people around me, my wife and kids, who work with me. 

'When you've been in this town for so long and I have to go to some place I've been going to for many, many, many years, and then all of a sudden I forget how to get there.'

Dorsett said he is 'trying to get better' and he has good days and bad days battling with the disease

Dorsett said he is 'trying to get better' and he has good days and bad days with the disease.

He added: 'I signed up for this when, I guess, I started playing football so many years ago.

'But, obviously, not knowing that the end was going to be like this. 

'But I love the game. The game was good to me. It's just unfortunate that I'm going through what I'm going through. 

'I'm in the fight, man. I'm hoping we can reverse this thing somehow.'

CTE has been discovered in a number of deceased NFL players.

It was detected in the brains of Junior Seau and Dave Duerson, both of whom committed suicide.
