This World Sleep Day, we ask the question: What is narcolepsy and why is it so often misunderstood?
Narcolepsy is not simply “falling asleep suddenly.” It is a chronic neurological condition that disrupts the brain’s ability to regulate sleep and wakefulness.
Whilst narcolepsy can look different from person to person, typically it is characterised by:
- Excessive daytime sleepiness (EDS)
- Brief sleep episodes during daily activities
- Cataplexy – a sudden loss of muscle tone triggered by strong emotions like laughter – in which individuals remain conscious (a detail often misunderstood)
Other common symptoms present as vivid dream-like hallucinations, sleep paralysis (being unable to move for a few seconds when falling asleep or waking), and broken sleep at night, all of which greatly impact an individual’s concentration, safety, work performance, social life and relationships.
Managing narcolepsy usually involves a combination of daily habits and medication. Treatment aims to improve daytime alertness, reduce REM-related symptoms, and help people function safely in daily life.
Although narcolepsy is considered uncommon, European data suggests that approximately 18–47 people per 100,000 are affected and, since delays in diagnosis are common, raising awareness is vital.
At Neuraxpharm, we are proudly committed to raising awareness of central nervous system disorders, encouraging communities to learn more and understand how conditions affect daily activities, and how people think, feel and function.
