Dutch Health Council warns of dementia risk from repeated head blows in sports
The Dutch Health Council is calling for major changes to sports rules to reduce head contact in activities like soccer, rugby, and combat sports, warning that repeated impacts to the head significantly increase the risk of long-term brain damage, including dementia, De Telegraaf reports.
In an advisory released Thursday, the council recommended altering game rules and introducing lighter balls to reduce the frequency and intensity of head impacts. The warning applies to athletes of all levels but places special emphasis on the vulnerability of children.
“Professional footballers are two to three times more likely to develop dementia than the average person,” the council stated, citing scientific findings on the long-term impact of repeated head trauma.
“Head contact increases the risk of dementia,” the Health Council said. In particular, it pointed to the practice of heading the ball in soccer as one of several common causes of repeated minor head injuries. According to the council, even a single blow to the head can lead to a concussion or other noticeable brain injury. Over time, the cumulative damage may have far more serious consequences.
The advisory also warned of possible links between frequent head impacts and other neurological conditions. According to the Health Council, head contact may contribute not only to dementia but potentially also to Parkinson’s disease and ALS, a severe neurodegenerative disorder.
The council's recommendations are not limited to soccer. Rugby players and combat sports athletes, who regularly experience forceful head collisions with opponents, are also considered at risk. For all athletes, the council emphasized that reducing head contact is a necessary step to protect brain health, both immediately and later in life.
The council placed particular importance on limiting head contact in youth sports. “Children are more vulnerable to brain injuries,” the council warned, making early intervention and protective measures even more urgent in schools and youth leagues.
Further concrete proposals will follow later this year. The Dutch Sports Council (Nederlandse Sportraad) is expected to publish its own set of recommendations this summer, aimed at advising the government, national sports federations, and individual athletes.
