RT Journal Article SR Electronic T1 The clinical presentation of paediatric narcolepsy in one Canadian sleep centre JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P1080 VO 40 IS Suppl 56 A1 Andrea Riekstins A1 Glenda Bendiak A1 Shelly Weiss A1 Indra Narang YR 2012 UL http://erj.ersjournals.com/content/40/Suppl_56/P1080.abstract AB Narcolepsy is primarily characterized by an overwhelming feeling of sleepiness with or without cataplexy. More recently, there has been a dramatic increase in newly diagnosed childhood narcolepsy and it is hypothesized that H1N1 may play a role in these new cases. The objective of this study is to review the demographics and presenting symptoms of children with narcolepsy in Toronto.Methods: At the Hospital for Sick Children, Toronto, we reviewed medical records and polysomnograms of patients with narcolepsy who presented to the sleep disorders clinic. All patients were referred with a history of excessive daytime sleepiness.Results:View this table:Conclusion: All patients had excessive daytime sleepiness. Interestingly over half of these young patients had cataplexy on presentation. H1N1 vaccination was not given to the majority of these patients. More research is needed to understand the recent increase in the prevalence of childhood narcolepsy with cataplexy.
