An athlete’s danger of growing mind illness from head trauma is not only restricted to CTE, or continual traumatic encephalopathy.
Analysis reveals repeated mind accidents, even these thought of delicate, are linked to the elevated danger of growing different neurodegenerative issues, together with Parkinson’s illness.
Only a single concussion in a lifetime will increase the chance of finally being recognized by 57%, based on the Parkinson’s Basis.

Speedy motion or an enormous blow to the pinnacle can injury mind cells, referred to as neurons, to the extent that it might disrupt their mobile capabilities.
“The cells themselves might not be broken… however their capacity to perform in a traditional manner is affected,” Jimenez-Shahed mentioned.
This might result in the buildup of poisonous proteins and set off a neurodegenerative course of.
Particular proteins are linked to sure illnesses, specialists say. For instance, CTE is related to a buildup of a protein referred to as tau.

The median age for a Parkinson’s analysis is about 65, Watts mentioned. At 54, Favre is on the youthful finish of that spectrum.
Parkinsonism – an umbrella time period for mind circumstances that trigger sluggish motion, rigidity and tremors – has been properly studied in boxers, Watts mentioned. One in all historical past’s most legendary boxers, Muhammad Ali, was recognized with the illness.
Nevertheless, the analysis amongst soccer gamers is not as strong. A 2023 research revealed in JAMA discovered contributors with a historical past of enjoying organized soccer had increased odds of Parkinsonism or Parkinson’s illness in contrast with these concerned in different organized sports activities. However different research have reported blended findings, Watts mentioned.
He mentioned researchers should decide if there’s a hyperlink.
“Soccer is such an enormous a part of American society,” he mentioned. “We have to know the solutions to this.”
