Heading a soccer ball can damage mental health. Researchers found that ex-football players are three and a half times more likely to die of dementia. They looked at the deaths of over 7,600 ex-players and the deaths of 23,000 people who did not play football. They found that the ex-players had a lot more brain injuries.
Football associations in the UK requested the research after a player died in 2002. Doctors said he died after "repeated minor brain traumas". A researcher said ex-players were more likely to suffer from diseases like Alzheimer's. He said they were less likely to die of diseases like heart disease and lung cancer.
Back to the soccer players lesson.
