First reports of narcolepsy with cataplexy (NC) in Russia were made by Mankovsky in 1925. The largest series of patients (n=110) was reported by A. Vein in 1964. However, until today narcolepsy remains relatively unknown in Russia. The aim of this study is to report clinical and polysomnography (PSG)/Multiple Sleep Latency Test (MSLT) results in the Russian population and compare them with the European Narcolepsy Network (EU-NN) data (n=1099) reported.
METHODS
Eleven sleep centers from Russia agreed to participate and completed a questionnaire including 58 questions concerning demographic, clinical, PSG and MSLT data.
RESULTS
There were 89 patients with a mean age of 35,6±16,9 years, 58% males and 42% females. Narcolepsy started at mean age of 25,6±14,6 years (range years). The mean Epworth Sleepiness Scale (ESS) was 18,4±3,5 points (range: 11-24). Sleep paralysis was reported by 59,1%, and hallucinations by 82% of patients. In MSLT 2 or more speed onsets of REM sleep periods (SOREMPs) were found in 81,6%. No center provided human leukocyte antigen (HLA) or cerebral spinal fluid (CSF) hypocretin data.
CONCLUSIONS
Clinical and neurophysiological data from this first study of the Russian Narcolepsy Network suggest a similar profile to the recently reported EU-NN data. The more severe and higher percentage of patients with cataplexy and presenting with both excessive daytime sleepiness (EDS) and cataplexy may reflect low awareness of narcolepsy in Russia.
