Fulton County Medical Examiner said it was opinion of Boston University doctor that regarding Demaryius Thomas "there is not a direct relationship between (CTE) and the development of the seizure disorder.''

He played for the Denver Broncos for five years.

The ex-Georgia Tech star was traded to the Houston Texans in the middle of the last decade. He played his last game with the New York Jets.

Boston University researchers posthumously diagnosed the wideout with Stage 2 chronic traumatic encephalopathy.

The term "chronic traumatic encephalomyelitis" is used to describe brain damage caused by repeated head traumas.

It's not clear how much of a factor it was.

A car accident caused Thomas to suffer from seizures. According to the BU Pathologist who studied Thomas' brain, seizures were not associated with the disease.

There were two different conditions for him.

There is no evidence that there is a relationship between chronic traumatic encephalomyelitis and a seizure disorder.

It has been noted that the chronic traumatic encephalopathy does not cause death.

She said thatCTE doesn't cause death. You do not die from chronic traumatic encephalopathy. What does it do to you?

Thomas' family noticed a change in behavior.

According to those closest to him, his behavior became increasingly erratic in the last year of his life, which was marked by the memory loss, paranoia and isolation that are hallmarks of chronic traumatic encephalopathy.

During his time in the league, Thomas was one of the most loved players. In the days and weeks after his death, there was a lot of praise for his character.

The board president of the Bountiful Hope Foundation, which Thomas worked for, said that Demaryius stopped to see, notice, and visit with people. This is what makes Demaryius special and makes me cry.

His teammates made comments about him.

Thomas once said that he tries to spread the love when he contributes to the Denver community.

He made a huge impact through his platform by attending Boys and Girls Club events, packing gifts for the holidays, and hosting football camps.
