WHAT IS NARCOLEPSY?

Narcolepsy is a rare long-term brain disorder that causes sufferers to suddenly fall asleep at inappropriate times.

It affects around 30,000 people in the UK and 200,000 in the US.

Symptoms include:

  • Excessive daytime sleepiness 
  • Falling asleep suddenly without warning
  • Temporary muscle control loss, leading to weakness and collapse
  • Sleep paralysis
  • Excessive dreaming and nighttime waking 

Narcolepsy is caused by lack of the brain chemical hypocretin, which regulates wakefulness.

This is thought to occur due to the immune system attacking cells that produce hypocretin or receptors that allow it to work. 

It can also be triggered by hormonal changes, stress and infections. 

There is no cure.

Sufferers are advised to have frequent naps throughout the day and stick to a strict bedtime routine. 

Medication can help to reduce daytime sleepiness and prevent loss of muscle control.
