Ronda Rousey: ‘I never wanted to talk about concussion. It felt like a weakness’

The former MMA fighter, once described as the world's most dominant athlete', reveals her fears for the future after a career riddled with glory and pain

I worry about it because we already have Alzheimer's and dementia in our family, and those family members did not get whacked on the head a whole bunch," Ronda Rousey says as she considers a future shrouded by the consequences of concussion and a past where she broke so many barriers for women before a shattering fall.

At her peak, in 2015, Rousey was described by Sports Illustrated as the world's most dominant athlete". She had changed a brutal sport to become the face of the UFC, the billion-dollar juggernaut which drives the popularity of MixedMartial Arts.
