The teenager who sleeps for 10 days
While most teenagers struggle to get out of bed in a morning, Louisa Ball might take 10 days to fully wake from her slumber, due to a very rare neurological disorder. So what's it like living with Kleine-Levin Syndrome?
Louisa has slept through holidays, friends' birthdays and half of her GCSEs.
In 2008, aged 14, she had been suffering from flu-like symptoms. She was at her school in Sussex when she started nodding off in class and behaving strangely.
"I didn't know what I was doing, what I was saying, everyone thought 'hey this isn't right,'" she recalls.
