Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. Are there subgroups within the IH-group, that can be retrospectively characterized out of data from polysomnography, PSG and MSLT.
2. What are the relationships between IH, and possible IH subgroups, and morbidity, mortality, and sick leave, using retrospective register data?
3. What is the natural course of IH, and possible IH subgroups, assessed with questionnaires that measures daytime sleepiness, depression, and insomnia?
4. How do subjects diagnosed with IH think about their disease, cope with it, and perceive the effects of treatments, using qualitative interviews? 185 individuals assessed and diagnosed at the Sleep unit, Uppsala university hospital between 2010-01-01 and 2019-12-31 will be contacted. After collecting informed consents, PSG and MSLT data will be analysed together with register data regarding morbidity, mortality, sick leave, and pharmacotherapy.Questionnaires used at the time of the original assessment will be reviewed and, to study the natural course of the syndrome, the same questionnaires will be sent to the participants by mail.
