Five patients with narcolepsy‐cataplexy (aged 31–69, mean age at onset 15 years) and their 47 relatives were examined. They were interviewed in detail, all patients and 16 relatives (including all symptomatic cases) were examined neurologically and a multiple sleep latency test and HLA‐typing were done. One case of narcolepsy and two cases of idiopathic hypersomnia were identified. All the other 45 relatives were symptom‐free. The observed rate of familial cases (1/5 for narcolepsy and 2/5 for idiopathic hypersomnia) corresponds the results of other recent studies.
