Doctors in Switzerland have used a brain-reading device to hold simple conversations with "locked-in" patients, who are too disabled to communicate.

In 2010 Kate Allatt became 'locked in' after suffering a stroke - she's now a motivational speaker, stroke activist and author.

Her friends helped to 鈥榰nlock鈥� her by creating a system of communication. She said: 鈥淭hey realised I wasn鈥檛 vegetative, and I was able to signal with my eyelids. They unlocked me by devising their own letterboard, one blink for no, two for yes.鈥�

鈥淏eing unlocked was like all your birthdays, Christmases and holding your baby in your arms at once 鈥� it was phenomenal,鈥� added Kate.
