    • A Longitudinal Study of Neurocognition in Dementia with Lewy Bodies Compared to Alzheimer`s Disease 

      Breitve, Monica Haraldseid; Chwiszczuk, Luiza; Hynninen, Kia Minna; Brønnick, Kolbjørn Selvåg; Auestad, Bjørn Henrik; Aarsland, Dag; Rongve, Arvid (Journal article; Peer reviewed, 2018-03)
      Introduction: There are relatively few longitudinal studies on the differences in cognitive decline between Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB), and the majority of existing studies have suboptimal ...

    • Duration of elevated heart rate Is an important predictor of exercise-induced troponin elevation 

      Bjørkavoll-Bergseth, Magnus; Kleiven, Øyunn; Auestad, Bjørn Henrik; Eftestøl, Trygve Christian; Oskal, Kay Raymond; Nygård, Martin; Skadberg, Øyvind; Aakre, Kristin Moberg; Melberg, Tor Harald; Gjesdal, Knut; Ørn, Stein (Peer reviewed; Journal article, 2020)
      Background The precise mechanisms causing cardiac troponin (cTn) increase after exercise remain to be determined. The aim of this study was to investigate the impact of heart rate (HR) on exercise‐induced cTn increase by ...

    • Early substance use cessation improves cognition-10 years outcome in first-episode psychosis patients 

      Weibell, Melissa Anne E; Johannessen, Jan Olav; Auestad, Bjørn Henrik; Bramness, Jørgen Gustav; Brønnick, Kolbjørn Kallesten; Haahr, Ulrik; Joa, Inge; Larsen, Tor Ketil; Melle, Ingrid; Ilner, Stein E.

    • Endurance exercise training volume is not associated with progression of coronary artery calcification 

      Kleiven, Øyunn; Bjørkavoll-Bergseth, Magnus; Omland, Torbjørn; Aakre, Kristin Moberg; Frøysa, Vidar; Erevik, Christine B.; Greve, Ole Jacob; Melberg, Tor Harald; Auestad, Bjørn Henrik; Skadberg, Øyvind; Edvardsen, Thor; Ørn, Stein (Peer reviewed; Journal article, 2020-02)
      Background Recent cross‐sectional studies have suggested a dose‐dependent relationship between lifelong exposure to physical activity and the burden of calcified coronary artery disease (CAD). No longitudinal studies have ...

    • Occult obstructive coronary artery disease is associated with prolonged cardiac troponin elevation following strenuous exercise 

      Kleiven, Øyunn; Omland, Torbjørn; Skadberg, Øyvind; Melberg, Tor Harald; Bjørkavoll-Bergseth, Magnus; Auestad, Bjørn Henrik; Bergseth, Rolf; Greve, Ole Jacob; Aakre, Kristin Moberg; Ørn, Stein (Journal article; Peer reviewed, 2019-06)

    • Race duration and blood pressure are major predictors of exercise-induced cardiac troponin elevation 

      Kleiven, Øyunn; Omland, Torbjørn; Skadberg, Øyvind; Melberg, Tor Harald; Bjørkavoll-Bergseth, Magnus; Auestad, Bjørn Henrik; Bergseth, Rolf; Greve, Ole Jacob; Aakre, Kristin Moberg; Ørn, Stein (Journal article; Peer reviewed, 2019-02)
      Background The underlying mechanisms of the exercise-induced increase in cardiac troponins (cTn) are poorly understood. The aim of this study was to identify independent determinants of exercise-induced cTn increase in a ...

    • Stress in School. Some Empirical Hints on the Circadian Cortisol of Children in Outdoor and Indoor Classes
