The study published in the scientific journal The Lancet Public Health analyzed the medical records of more than 6,000 Swedish Premier League players from 1re division between 1924 and 2019.

Football players had a 1.5 times higher risk than the control group of developing diseases like Alzheimer’s and other types of dementia. Goalkeepers are an exception in the study, as they don’t make heads.
