Participants with a dementia diagnosis (n = 2049 cases) were identified. ...

    • Leisure Time Physical Activities’ Association With Cognition and Dementia: A 19 Years’ Life Course Study 

      Johnsen, Bente; Strand, Bjørn Heine; Martinaityte, Ieva; Lorem, Geir Fagerjord; Schirmer, Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-15)
      Introduction: Cognitive impairment is one of the main disabilities in dementia. Physical activity (PA) has been suggested as protective for dementia. However, the findings are disparate in studies, and the question of whether this is because of reverse causality is still open. We aimed to explore the association of PA with cognition in people who later developed dementia compared to those who ...

    • Trends for cognitive function and dementia in a general population; Risk factors, trajectories, and incidence 

      Johnsen, Bente (Doctoral thesis; Doktorgradsavhandling, 2024-04-25)
      Med økende levealder er kognitiv sunn aldring viktig for et godt liv i alderdommen. Kognisjon hos unge voksne har økt det siste århundret, men det er få studier over tid på personer over 60 år. Risikofaktorer for kognitiv svikt og demens er identifisert, og en av de mest lovende beskyttende faktorer er fysisk aktivitet. Demensprevalensen er høyere i Norge enn sammenlignbare land, og longitudinelle ...
