Abstrakt     Hypersomnias are sleep disorders with lengthened night sleep, or excessive daytime sleepiness. When excessive sleep becoines unpleasant and disturbs the patient in his normal life, we call it hypersoinnia. The most studied disorder of excessive somnolence is narcolepsy. Patients with idiopathic hypersomnia and patients with hypersomnia associated with dysthymia may have similar complaints of sleepiness: lengthened sleep, difficulties in awakening, permanent low level of vigilance, long non refreshing naps. Different reports from questionnaires, scales and behavioural observations were made in these patients. The criteria were not strict enough to distinguish between dysthymia and idiopathic hypersomnia. Polygraphic studies devoted to idiopathic hypersomnia and hypersomnia associated with dysthymia are rare. Furthermore, they have been done in patients representing a severe mood disorder or a major depressive disorder. In our patients refereed to sleep disorder centre with a complaint of hypersomnia, dysthymia, a form of mild depression was diagnosed later. In our study we compared the polysomnographic characteristics of patients with idiopathic hypersomnia and dysthymic patients coinplaining of hypersomnia to an unquestionable somnolent group coinposed of narcoleptic patients, and non somnolent group, composed of normal subjects. 12 subjects with hypersomnia associated with dysthymia assessed according to DSM-IV (45) criteria, and 12 subjects with idiopathic hypersomnia assessed according to ICSD criteria (69) were selected for the study. 12 narcoleptic patients and 12 normal good sleeper subjects served as reference groups. The schedule of the 44-h study was the following: the first night served as an adaptation and selection night. The following day was used for Mean Sleep Latency Test (MSLT), and the second night and day were devoted to continuos polygraphic recording. (Abstract truncated at 2000 characters.)
