CATNAP® PEDIATRIC NARCOLEPSY

A Registry Learning Guide

According to the American Sleep Association®, narcolepsy affects approximately 1 in 2,000 individuals. Most patients present with symptoms during childhood or early adolescence.

What is Narcolepsy?

Narcolepsy is a chronic neurologic condition that affects the brain. It can disrupt the brain’s ability to regulate normal sleep-wake cycles.

People with narcolepsy may feel very sleepy during the day. They may also fall asleep during normal activities, even when trying to stay awake. These symptoms can make everyday tasks more difficult.

What are the Characteristics of Narcolepsy?

Excessive sleepiness

Hallucinations

Sleep paralysis

Partial or total loss of muscle control

Narcolepsy in Children and Adolescents 

Diagnosing pediatric narcolepsy can be challenging. Symptoms generally begin between the ages of 10 and 25. However, symptoms that begin before age 18 are more likely to be missed. As a result, some children may not receive a narcolepsy diagnosis until adulthood.

Better awareness can help with earlier recognition. This includes awareness among parents, school professionals, children and adolescents, the general public, and pediatric healthcare providers.

Factors that can make pediatric narcolepsy difficult to diagnose include: 

  • Different duration of sleep in children 
  • Children’s difficulty verbalizing their symptoms 
  • Different appearance of cataplexy, a common symptom, in children 
  • Misinterpretation of the major symptoms by adults 
  • Misdiagnosis as other conditions, for example: 
    • Excessive tiredness often leads to the diagnosis of chronic fatigue
    • Hallucinations are often mistaken for a sign of psychosis or epilepsy

A Lack of Real-World Data in Pediatric Narcolepsy to Advance Quality of Life and Medical Treatment

Narcolepsy can significantly affect many areas of a child’s life, including play, school, extracurricular activities, social relationships, and self-esteem.
However, there is limited data available to quantify and track these everyday effects throughout childhood.

Registries in narcolepsy exist, but they:

  • Do not focus on the pediatric population 
  • Do not incorporate data input directly from the patients and caregivers

Collecting information directly from patients and caregivers can provide a more comprehensive view of their experiences. This may include observational data, such as quality of life, health resource utilization, and activities of daily living.
This approach can also support the collection of natural history data. These data can be difficult to obtain because many patients experience a long period between symptom onset and diagnosis.

About CATNAP® Registry

Children, Adolescents and their providers: The Narcolepsy Assessment Partnership (CATNAP)® was designed to address these unmet needs. The registry includes a patient portal and a clinician/researcher portal to capture relevant data.
It also provides collaborative tools for data analysis and visualization. The data collected through CATNAP® can contribute valuable scientific information to the field of pediatric narcolepsy.
