Episode 13: Football and dementia

We’ve all heard of football players (that’s “soccer players” for US listeners) tearing their hamstrings, spraining their ankles, and injuring their knees. But could all that heading of the football, whether or not it causes a concussion, be having a subtler but much more damaging long-term effect on the player’s brain?

In this episode of The Studies Show, Tom and Stuart—the latter of whom, as you’ll discover, is not a massive fan of sport in general—discuss research on whether playing the nation’s favourite sport might lead to dementia in later life. If it does, how does it happen? And is playing football worthwhile regardless?

The Studies Show is sponsored by Works in Progress, an online magazine filled with longform essays on science, technology, and human progress. How do we encourage people to support economic growth? How did Mexico build its state in the 19th Century? And why did it take so long to develop a malaria vaccine? These are just some of the topics covered in the most recent issue.

The Studies Show is also sponsored by the i, the UK’s smartest daily newspaper. It’s filled with exclusive reporting, comment, analysis, and so much more, and you can get a cut-price deal on digital subscriptions—which include full access to Stuart’s columns and his subscriber-only science newsletter—by following this special podcast link.
