The Burden of Narcolepsy in Adults: A Population Sampling Study Using Personal Media

Area of Science:

• Neurology
• Sleep Medicine
• Patient-Reported Outcomes

Background:

• Narcolepsy is a chronic neurological disorder characterized by excessive daytime sleepiness and other debilitating symptoms.
• Understanding the full spectrum of narcolepsy symptoms and their impact on patients' lives is crucial for effective management.

Purpose of the Study:

• To investigate the diverse range of narcolepsy symptoms and their associated burden in a large patient cohort.
• To identify which symptoms contribute most significantly to the overall patient experience.

Main Methods:

• Utilized the Narcolepsy Monitor mobile application for symptom tracking in 746 diagnosed narcolepsy patients (aged 18-75).
• Collected baseline data on the presence and burden of 20 distinct narcolepsy symptoms.
• Analyzed symptom frequency, burden levels, and demographic influences (e.g., gender).

Main Results:

• Excessive daytime sleepiness (97.2%) and lack of energy (95.0%) were the most prevalent symptoms.
• Cognitive (concentration 93.0%, memory 91.4%) and psychiatric (mood 76.8%, anxiety/panic 76.4%) symptoms were frequently reported and burdensome.
• Sleep paralysis and cataplexy were less commonly reported as highly bothersome; females reported higher burden for anxiety/panic, memory, and lack of energy.

Conclusions:

• Confirms an extensive spectrum of narcolepsy symptoms beyond core features.
• Individual symptom burden varies, with less recognized symptoms significantly impacting patients.
• Treatment strategies should encompass the broader symptom profile, not solely classical narcolepsy symptoms.
