A putative ... -
Cognitive performance in DSWPD patients upon awakening from habitual sleep compared with forced conventional sleep
Solheim, Brandy; Olsen, Alexander; Kallestad, Håvard; Langsrud, Knut; Bjorvatn, Bjørn; Gradisar, Michael; Sand, Trond (Journal article; Peer reviewed, 2018)Difficult early morning awakening is one of the defining symptoms of delayed sleep–wake phase disorder. It is accompanied by low cognitive arousal and drowsiness resulting in difficulty concentrating and focusing attention ... -
Do physical activity and body mass index modify the association between chronic musculoskeletal pain and insomnia? Longitudinal data from the HUNT study, Norway.
Skarpsno, Eivind S.; Nilsen, Tom Ivar Lund; Sand, Trond; Hagen, Knut; Mork, Paul Jarle (Journal article; Peer reviewed, 2017)We investigated the prospective association between chronic musculoskeletal pain and risk of insomnia, and if leisure‐time physical activity and body mass index modify this association. The study comprised historical data ... -
Epileptological aspects of juvenile neuronal ceroid lipofuscinosis (CLN3 disease) through the lifespan
Arntsen, Vibeke; Strandheim, John; Helland, Ingrid B; Sand, Trond; Brodtkorb, Eylert (Journal article; Peer reviewed, 2019)Purpose Juvenile neuronal ceroid lipofuscinosis (CLN3 disease) is the most common neurodegenerative disorder in childhood with survival until young adult age. Visual loss is followed by epilepsy, cognitive, neuropsychiatric, ... -
Experimental pain and migraine: Investigating the effect of non-invasive cortical modulation of pain, and phasic alterations of pain in migraineurs
Uglem, Martin (Doctoral theses at NTNU;2018:130, Doctoral thesis, 2018)Background: Both clinical symptoms, imaging findings, and neurophysiological measures suggest varying cyclic alterations in CNS-function between, before, during and after the migraine headache. Altered pain perception ... -
Exploring difficult morning awakening in Delayed Sleep Phase Syndrome using polysomnography
Solheim, Brandy (Master thesis, 2012)Objective: Difficult morning awakening is an important symptom of delayed sleep phase syndrome (DSPS), but there is little knowledge about this phenomenon. The first aim of this study was to test the hypothesis that DSPS ... -
Fluctuations of sensorimotor processing in migraine: A controlled longitudinal study of beta event related desynchronization
Mykland, Martin Syvertsen; Bjørk, Marte-Helene; Stjern, Marit; Omland, Petter Moe; Uglem, Martin; Sand, Trond (Journal article; Peer reviewed, 2019)Background The migraine brain seems to undergo cyclic fluctuations of sensory processing. For instance, during the preictal phase, migraineurs experience symptoms and signs of altered pain perception as well as other ... -
Habituation of laser-evoked potentials by migraine phase: a blinded longitudinal study.
Uglem, Martin; Omland, Petter Moe; Stjern, Marit; Gravdahl, Gøril Bruvik; Sand, Trond (Journal article; Peer reviewed, 2017)Background Migraineurs seem to have cyclic variations in cortical excitability in several neurophysiological modalities. Laser-evoked potentials (LEP) are of particular interest in migraine because LEP specifically targets ... -
