    How frequent narcolepsy is in the population (prevalence, the proportion of the population with narcolepsy) is difficult to estimate, and depends on the methods used to measure it. For example, the estimate is higher if based on self-report and on questionnaire compared to the diagnosis based on confirmatory sleep study and more objective testing. It also varies from one ethnic group to another. There is no specific study on the Australian population but the prevalence would be similar to other countries. The prevalence in Europe and North America is between 20 and 50 cases in 100,000. It is higher among the Japanese and Chinese (160 to 284 in 100,000).  In Israel the prevalence is reported to be very low  less than 1 in 100,000. The use of the European and North America estimate of 20 to 50 per 100,000 is the best approximation. For more information on Narcolepsy click here.
