Does pain sensitivity change by migraine phase? A blinded longitudinal study
Hagen, Knut; Omland, Petter Moe; Stovner, Lars Jacob; Sand, Trond Halfdan; Uglem, Martin; Tronvik, Erling Andreas; Nilsen, Kristian Bernhard; Linde, Anders Mattias (Journal article; Peer reviewed, 2016)Objective: Studies suggest that pain thresholds may be altered before and during migraine headaches, but it is still debated if a central or peripheral dysfunction is responsible for the onset of pain in migraine. The ... -
The effect of sleep restriction on laser evoked potentials, thermal sensory and pain thresholds and suprathreshold pain in healthy subjects
Ødegård, Siv Steinsmo; Omland, Petter Moe; Nilsen, Kristian Bernhard; Stjern, Marit; Gravdahl, Gøril Bruvik; Sand, Trond (Peer reviewed; Journal article, 2015)Objective: Sleep restriction seems to change our experience of pain and reduce laser evoked potential (LEP) amplitudes. However, although LEP-habituation abnormalities have been described in painful conditions with comorbid ... -
Effects of insufficient sleep on sensorimotor processing in migraine. A randomised, blinded crossover study of event related beta oscillations
Mykland, Martin Syvertsen; Uglem, Martin; Bjørk, Marte-Helene; Matre, Dagfinn; Sand, Trond Halfdan; Omland, Petter Moe (Peer reviewed; Journal article, 2023)Background Migraine has a largely unexplained connection with sleep and is possibly related to a dysfunction of thalamocortical systems and cortical inhibition. In this study we investigate the effect of insufficient sleep ... -
Experimental pain after sleep restriction and cortical excitability in migraine patients: From cross-sectional studies in the interictal phase to crossover studies on the effect of sleep restriction
Neverdahl, Jan Petter (Doctoral theses at NTNU;2024:10, Doctoral thesis, 2024)Migraine is a common and debilitating primary headache disorder. Despite having pronounced personal, societal, and economical costs, the pathophysiology of migraine is not fully elucidated. Migraine patients experience ... -
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 ... -
Experimental sleep restriction increases latency jitter in pain elicited cortical responses
Hansen, Johannes Orvin; Omland, Petter Moe; Nilsen, Kristian Bernhard; Sand, Trond; Matre, Dagfinn (Peer reviewed; Journal article, 2021)Objective Previous studies have shown increased pain scores to painful stimulation after experimental sleep restriction, but reduced or unchanged magnitude of the event related potentials (ERPs) when averaged in the ... -
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 ... -
Insufficient sleep may alter cortical excitability near the migraine attack: A blinded TMS crossover study
Mykland, Martin Syvertsen; Uglem, Martin; Stovner, Lars Jacob; Brenner, Eiliv; Snoen, Mari Storli; Gravdahl, Gøril Bruvik; Sand, Trond Halfdan; Omland, Petter Moe (Peer reviewed; Journal article, 2023)Background Migraine is a brain disorder with a multifaceted and unexplained association to sleep. Brain excitability likely changes periodically throughout the migraine cycle. In this study we examine the effect of ... -
Migraine and sleep: The effects of insufficient sleep on brain function in migraine
Mykland, Martin Syvertsen (Doctoral theses at NTNU;2023:330, Doctoral thesis, 2023)Background Migraine affects about 15 % of the adult population aged 15-64 years old. The combined large prevalence and considerable disability of migraine makes it the first cause of most years lived with disability below ... -
Non-invasive cortical modulation of experimental pain in migraine
Uglem, Martin; Omland, Petter Moe; Engstrøm, Morten; Gravdahl, Gøril Bruvik; Linde, Mattias; Hagen, Knut; Sand, Trond (Journal article; Peer reviewed, 2016)Objective: To test the hypothesis that secondary somatosensory cortex (S2) is involved in the migraine pathogenesis, by exploring the effect of navigated repetitive transcranial magnetic stimulation (rTMS) to S2 on ... -
Obstructive sleep apnoea and headache: the HUNT3 polysomnography study
Filosa, James (Master thesis, 2021)Bakgrunn: Hovedformålet var å studere sammenhengen mellom obstruktiv søvnapné (OSA) og hodepine i populasjonsbasert utvalg. Studien hadde også som mål å studere sammenhengen mellom hodepine og komorbid insomni og OSA ... -
Retinal structure and visual pathway function at school age in children born extremely preterm: a population-based study
Ingvaldsen, Sigrid Hegna; Moljord, Kyrre; Grøtting, Arnstein; Omland, Petter Moe; Dammann, Olaf; Austeng, Dordi Kristine; Morken, Tora Sund (Peer reviewed; Journal article, 2023)Background Children born extremely preterm (gestational age < 28 weeks) show reduced visual function even without any cerebral or ophthalmological neonatal diagnosis. In this study, we aimed to assess the retinal structure ... -
Sleep and Pain: An EEG study of how sleep affects pain perception
Rødsjø, Eline (Master thesis, 2020)Bakgrunn: Eksperimentelle studier har vist at søvnmangel er assosiert med endringer i smertepersepsjon. Flere hjerneavbildningsstudier trengs for å utvikle objektive nevrofysiologiske korrelater til smerte. Hensikt: Denne ... -
