Lily Clarke, 21, has a rare condition called Kleine-Levin syndrome, which makes her nod off for a month at a time.
A student has revealed how she has missed birthdays and university exams - because she has been fast asleep.

Lily Clarke, 21, has a rare condition called Kleine-Levin syndrome, which makes her nod off（打盹） for a month at a time. She wakes only to eat and drink before returning to slumber²（睡眠） .

Over three years she was seen by seven different consultants⁴ and underwent a battery of medical tests, but was only diagnosed when her mother read about a similar case in the Daily Mail in February 2010.

'As soon as I read the symptoms I recognised them,' Adele, 47 said.

'It was such a relief to finally find someone who knew what I was describing.'

Ms Clarke said the condition first came on when the family, from Halsemere, Surrey, went ice skating in November, 2007.

'Lily was uncharacteristically quiet and kept saying: "My head feels strange - I don't feel well." I just thought she was coming down with a cold.'

After the skating they went to a restaurant and Lily fell asleep through the whole meal.

Lily refused to get out of bed for the next 25 days, barely eating or drinking. She slept for 23 hours a day and couldn't bear noise or light.

A month later Lily was due to take some mock exams（模拟考） but suffered a further three-week episode before making a similar 'miraculous⁵' recovery. A third two-week episode followed a few days after her 18th birthday and her parents had to cancel her party.

Doctors suggested conditions from migraine（偏头痛） to ME and depression. A consultant³ neuropsychiatrist suggested Lily was suffering from 'recurrent depressive episodes'. She was prescribed anti-depressants and a course of cognitive⁶ behavioural therapy.

However, a fourth episode followed in July 2008. This time she was awake for a few hours each day but was afraid to be alone.

'She behaved like a four year old, cuddling her teddy, sucking her thumb and crying that she thought she was going to die,' Ms Clarke said.

Lily continued to have regular episodes and although she managed to go to university she was falling behind with her studies. Without an official diagnosis⁷ she could not be granted 'extenuating⁸ circumstances.'

Then in February 2010, Ms Clarke read an article in the Daily Mail about Louisa Ball, who suffered with the 'sleeping sickness' Kleine-Levin syndrome.

She contacted the paper who put her in touch with Louisa's parents and the KLS Foundation in America. They advised her to see Professor David Nutt at the Chelsea and Westminster Hospital, who confirmed Lily had the condition.

The symptoms match the ones Lily suffered. Sadly there is no cure, although there is some suggestion that some sufferers do grow out of it.

She met with two other British mothers who had children with the rare syndrome and together they set up the website www.kls-support.org.uk to raise awareness⁹.

Ms Clarke said: 'It is only through talking to other parents, I now understand that in an episode Lily feels like she is trapped in a horror film where everything is confusing.

'Her brain cannot process information. When asleep, her dreams are vividly¹⁰ real. When awake she hallucinates（出现幻觉） and nothing feels real.'

To help Lily cope, they have no visitors during episodes and keep to a quiet and calm routine. Lily also watches a familiar children's film over and over.

Ms Clarke said she now felt more confident how to deal with the condition and was proud of how Lily was coping.

'Lily has learnt regardless of what she has missed out on, she needs to pick herself up and live every moment of her life to the full.'
