Struggling to stay awake during the day can be mistaken for normal tiredness, but ongoing daytime sleepiness can be a sign that something is not quite right. 

 

Along with feeling sleepy during the day, some people may also experience other symptoms, such as sudden muscle weakness, very vivid dreams, feeling unable to move when falling asleep or waking up, and/or disturbed sleep at night. When these symptoms happen together, they may point to narcolepsy. 

 

In this video, sleep expert Professor Yves Dauvilliers explains narcolepsy and how to recognise it, including: 

  • Normal tiredness vs excessive daytime sleepiness 
  • What narcolepsy is
  • When and where to seek help 

 

Clinical takeaways

  • Feeling sleepy all the time is not normal. Struggling to stay awake during the day may be a sign of an underlying issue that may require further attention 
  • When ongoing sleepiness happens together with other symptoms, such as sudden loss of muscle strength, very vivid dreams, feeling unable to move while lying in bed, and/or waking up often during the night, it could be narcolepsy 
  • For many people, narcolepsy is linked to low levels of orexin, a brain chemical that regulates wakefulness. Early diagnosis is important to help manage it appropriately with available treatments 
  • Recognising these signs and speaking with a doctor is the first step in understanding what may be happening and accessing appropriate care as early as possible 
  • Recognise the signs and symptoms of narcolepsy
    Help people understand the key features that set narcolepsy apart from other conditions, such as sudden muscle weakness (cataplexy), excessive daytime sleepiness, and disrupted night-time sleep and why these symptoms should not be ignored 
  • Understand the importance of early diagnosis
    Having the right tests and speaking to a healthcare professional early can help prevent years of misdiagnosis and improve quality of life 
  • Learn what causes narcolepsy type 1
    Find out how narcolepsy type 1 is linked to low levels of orexin, and how this affects symptoms like sleepiness, cataplexy, and other related health issues
