Abstract

We report the first four German cases of hypnic headache according to the criteria suggested in the literature. Furthermore, we present the results of polysomnography in two theses cases with hypnic headache occurring during REM sleep. In one case, hypnic headache was also associated with periodic limb movements. Although mean nocturnal oxygen saturation was decreased in another patient, nightly oxygen inhalation did not result in an improvement of the headache.
