Journal ArticleDOI
Delayed sleep phase syndrome: A placebo‐controlled cross‐over study on the effects of melatonin administered five hours before the individual dim light melatonin onset
TL;DR: The results show that analysis of DLMO of patients suffering from DSPS is important both for diagnosis and therapy, and actigraphy showed a significant advance of sleep onset and polysomnography, a significant decreased sleep latency.
Journal ArticleDOI

TL;DR: In this paper, the authors have validated radioimmunoassay (RIA) measurements of melatonin in saliva in patients diagnosed as suffering from a typical circadian rhythm disorder: Delayed Sleep Phase Syndrome (DSPS) based on these results, they have defined the equivalent salivary DLMO concentration to be 4 pg/ml

Journal ArticleDOI
Melatonin-responsive headache in delayed sleep phase syndrome: preliminary observations
TL;DR: The occurrence of headache and its change after treatment with melatonin 5 mg were studied in 30 patients with delayed sleep phase syndrome.
