A growing number of people within the normal population suffers severely from daytime sleepiness. In some cases, this is caused by narcolepsy – a rare and compromising, still underdiagnosed and not well understood disorder. The 10th Swiss Narcolepsy Day offers opportunities to address clinical aspects of narcolepsy and the narcoleptic borderland and to report on clinical and scientific progress in disease management. Together with the Swiss Narcolepsy Network (www.snane.ch) our goal is to find innovative new strategies that support the improvement of the patient’s medical care.
