Table 1 shows the number and median age of patients in each group, and median age at symptom debut and median duration of the disorder in each patient group. It also shows the number and percentage of patients in each group who reported hypnagogic hallucinations, sleep paralysis and relatives with similar sleep disorder. (*Number of patients reduced to 28 due to incomplete answers to the questionnaire). The total number of reported relatives in each group is given in brackets. N = Narcolepsy, hcrt = hypocretin-1
