    • Cognitive behavioral therapy for insomnia in euthymic bipolar disorder: study protocol for a randomized controlled trial 

      Steinan, Mette Kvisten; Krane-Gartiser, Karoline; Langsrud, Knut; Sand, Trond; Kallestad, Håvard; Morken, Gunnar (Journal article; Peer reviewed, 2014)
      Background Patients with bipolar disorder experience sleep disturbance, even in euthymic phases. Changes in sleep pattern are frequent signs of a new episode of (hypo)mania or depression. Cognitive behavioral therapy for ...

    • 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 ...

    • Contact-free actigraphy: Measuring sleep with a radar sensor 

      Heglum, Hanne Siri Amdahl (Doctoral theses at NTNU;2023:68, Doctoral thesis, 2023)
      Background Sleep is an essential biological process, and sleep deprivation and sleep-related disorders have devastating personal and societal consequences. The diagnosis and effective treatment of sleeprelated problems ...

    • Contact-free radar recordings of body movement can reflect ultradian dynamics of sleep 

      Heglum, Hanne Siri Amdahl; Drews, Henning Johannes; Kallestad, Håvard; Vethe, Daniel; Langsrud, Knut; Sand, Trond; Engstrøm, Morten (Peer reviewed; Journal article, 2022)
      This work aimed to evaluate if a contact-free radar sensor can be used to observe ultradian patterns in sleep physiology, by way of a data processing tool known as Locomotor Inactivity During Sleep (LIDS). LIDS was designed ...

    • Distinguishing sleep from wake with a radar sensor: A contact-free real-time sleep monitor 

      Heglum, Hanne Siri Amdahl; Kallestad, Håvard; Vethe, Daniel; Langsrud, Knut; Sand, Trond; Engstrøm, Morten (Journal article; Peer reviewed, 2021)
      This work aimed to evaluate whether a radar sensor can distinguish sleep from wakefulness in real time. The sensor detects body movements without direct physical contact with the subject and can be embedded in the roof of ...

    • 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 (Peer reviewed; Journal article, 2022)
      Evening exposure to short-wavelength light has disruptive effects on circadian rhythms and sleep. These effects can be mitigated by blocking short-wavelength (blue) frequencies, which has led to the development of evening ...

    • Poorer sleep health is associated with altered brain activation during cognitive control processing in healthy adults 

      Smevik, Hanne; Habli, Sarah; Saksvik, Simen Berg; Kliem, Elisabeth; Evensmoen, Hallvard Røe; Conde, Virginia; Petroni, Agustin; Asarnow, Robert F.; Dennis, Emily L.; Eikenes, Live; Kallestad, Håvard; Sand, Trond Halfdan; Thompson, Paul M.; Saksvik-Lehouillier, Ingvild; Håberg, Asta; Olsen, Alexander (Peer reviewed; Journal article, 2023)
      This study investigated how proactive and reactive cognitive control processing in the brain was associated with habitual sleep health. BOLD fMRI data were acquired from 81 healthy adults with normal sleep (41 females, age ...

    • The prevalence and stability of sleep-wake disturbance and fatigue throughout the first year after mild traumatic brain injury 

      Saksvik, Simen Berg; Karaliute, Migle; Kallestad, Håvard; Follestad, Turid; Asarnow, Robert F.; Vik, Anne; Håberg, Asta; Skandsen, Toril; Olsen, Alexander (Peer reviewed; Journal article, 2020)
      In this prospective, longitudinal study, we aimed to determine the prevalence and stability of sleep-wake disturbance (SWD) and fatigue in a large representative sample of patients (Trondheim mild traumatic brain injury ...

    • Sleep disturbance: Clinical significance in mental health care and cognitive factors 

      Kallestad, Håvard (Doktoravhandlinger ved NTNU, 1503-8181; 2012:340, Doctoral thesis, 2012)
      Omkring en av ti nordmenn lider av kronisk søvnforstyrrelse. Flere studier har vist at individer som blir rammet av dette har høyere risiko for flere negative hendelser slik som utvikling av andre psykiske lidelser, mer ...

    • Sleep structure and awakening threshold in delayed sleep-wake phase disorder patients compared to healthy sleepers 

      Solheim, Brandy; Langsrud, Knut; Kallestad, Håvard; Engstrøm, Morten; Bjorvatn, Bjørn; Sand, Trond (Journal article; Peer reviewed, 2018)
      Study Objectives Difficult early morning awakening is a primary symptom of delayed sleep-wake phase disorder (DSWPD), however, it remains poorly investigated. Our main objective was to quantify the awakening threshold in ...
