Narcolepsy is often thought of as an adult sleep disorder.7 However, symptoms most commonly start in childhood or adolescence. 7 While the five major symptoms of narcolepsy are the same for children and adults, they can present differently.1,8 Misdiagnosis is common, and people with narcolepsy can experience symptoms for more than a decade before getting the right diagnosis. 6,7
