A woman who developed a mystery illness feared she might die every time she laughed.

Claris Diaz, who now lives in Cardiff but is originally from California, developed a very rare brain disease that meant she could be killed by prolonged laughter or a chuckle.

Claris - who has undergone brain operations to successfully correct the problem - told Wales Online: "Sometimes I would lose my speech and occasionally I would urinate myself.

"It occurred almost every single time that I went to my band practice class where I was learning how to play the flute.

"If it wasn't during band practice, it would happen whenever I would laugh extensively or participate in any physical activity that raised my breathing rate."
