A blinded controlled polysomnographic study” published in JHP 2013 Feb 14;14(1):12. We hypothesize that migraineurs need ... -
Evening light environments can be designed to consolidate and increase the duration of REM-sleep
Vethe, Daniel; Drews, Henning Johannes; Scott, Janine Linda; Engstrøm, Morten; Heglum, Hanne Siri Amdahl; Grønli, Janne; Wisor, J.P.; Sand, Trond; Lydersen, Stian; Kjørstad, Kaia; Faaland, Patrick; Vestergaard, Cecilie Lund; Langsrud, Knut; Kallestad, Håvard (Journal article; Peer reviewed, 2022)Evening exposure to short-wavelength light has disruptive effects on circadian rhythms and sleep.

Engstrøm, Morten; Hagen, Knut; Bjørk, Marte Helene; Stovner, Lars Jacob; Gravdahl, Gøril Bruvik; Stjern, Marit; Sand, Trond (Peer reviewed; Journal article, 2013-02-14)Background: Our aim was to compare subjective and objective sleep quality and arousal in migraine and to evaluate the relationship between sleep quality and pain thresholds (PT) in controls, interictal, preictal and postictal ... -
Sleep-related and non-sleep-related migraine: interictal sleep quality, arousals and pain thresholds
Engstrøm, Morten; Hagen, Knut; Bjørk, Marte Helene; Gravdahl, Gøril Bruvik; Sand, Trond (Peer reviewed; Journal article, 2013-08-06)Background: The mechanisms associating sleep and migraine are unknown. No previous polysomnographic (PSG) or pain-threshold (PT) study has compared patients with sleep-related migraine attacks (SM), non-sleep related ...
