Here is some key information about narcolepsy, cataplexy, and excessive daytime sleepiness (EDS). If you have any questions, please let me know how I can help.

It was a pleasure speaking with you. As we discussed, here is additional information about narcolepsy, cataplexy, and excessive daytime sleepiness (EDS). If you have any questions, please let me know how I can help.

What are the annual direct medical costs of narcolepsy?
Learn more about the economic burden of narcolepsy and see how this disabling disorder is often misdiagnosed in the clinical setting.1
Question: How often do providers misdiagnose narcolepsy?
Fact: Up to 60% of patients are initially diagnosed as having other conditions1,2:
attention-deficit/hyperactivity disorder
psychiatric disorders
obstructive sleep apnea
insufficient sleep
side effects of medication
circadian rhythm disorders
periodic limb movements

Two online surveys reveal that providers and patients agree more treatment options are needed1,2
Online Surveys of Unmet Needs Included:
286 narcolepsy-treating HCPs—sleep specialists, neurologists, psychiatrists, pulmonologists, primary care physicians (July 2018)
200 US adults living with narcolepsy (March 2018)
What treatment options would you consider for patients with narcolepsy?

The survey was conducted online in March 2018 by Versta Research on behalf of Harmony Biosciences, LLC. The Narcolepsy Network collaborated on the patient survey.
Type 1 and Type 2 narcolepsy differ by the presence of cataplexy, a debilitating condition
The fact is, all people with narcolepsy have excessive daytime sleepiness (EDS). But did you know that along with this irrepressible need to sleep, almost 3 out of 4 have cataplexy too?1,2
Imagine having a sudden and brief loss of muscle strength or muscle tone that could be brought on by strong emotions or certain situations, like laughing or being startled. That is what happens when patients have cataplexy, and it often strikes unexpectedly.2,3

Imagine making a witty remark or hearing a joke, then suddenly collapsing from a complete loss of muscle control
Strong emotions and specific situations can trigger cataplexy
Everyday activities can trigger cataplexy—including being angry, unexpectedly meeting an acquaintance, or just being startled. These events can cause complete loss of muscle control in the face and jaw, slurred speech, and jerking and twitching of the face and arms.1
Learn more about the symptoms of cataplexy and how partial and complete cataplexy differ.
