Leisure Time Physical Activities’ Association With Cognition and Dementia: A 19 Years’ Life Course Study
(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 ... -
Short-term temporal variation of coastal marine eDNA
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-23)Temporal variation in eDNA signals is increasingly explored for understanding community ecology in aquatic habitats.

Anxiolytic-like Effects of the Positive GABA-B Receptor Modulator GS39783 Correlate with Mice's Individual Basal Anxiety and Stress Reactivity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-16)Positive gamma-aminobutyric acid type B (GABAB) receptor modulators such as GS39783 have showed anxiolytic-like effects in several studies while such effects were absent in other studies. These conflicting findings led us hypothesize that the anxiolytic-like effects of such compounds depend on the individual basal anxiety and/or the anxiogenic properties of the used tests. The present study ... -

Experiences of Norwegian Mothers Attending an Online Course of Therapeutic Writing Following the Unexpected Death of a Child
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-27)The unexpected death of a child is one of the most challenging losses as it fractures survivors’ sense of parenthood and other layers of identity. Given that not all the bereaved parents who have need for support respond well to available treatments and that many have little access to further intervention or follow-up over time, online interventions featuring therapeutic writing and peer support ... -
