    • Amyloid plaques and symptoms of depression links to medical help-seeking due to subjective cognitive decline 

      Espenes, Ragna; Kirsebom, Bjørn-Eivind; Eriksson, Cecilia Magdalena; Waterloo, Knut K; Hessen, Erik; Johnsen, Stein Harald; Selnes, Per; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-02)
      <i>Background:</i> Subjective cognitive decline (SCD) is associated with an increased risk of Alzheimer’s disease (AD). However, patients reporting SCD to their general practitioner are not always referred to a memory clinic.<p> <p><i>Objective:</i> To investigate whether prior history of medical help-seeking is associated with AD biomarker abnormality, worse cognitive performance, and/or depressive ...

    • Association of Klotho protein levels and KL-VS heterozygosity with Alzheimer disease and amyloid and tau burden 

      Grøntvedt, Gøril Rolfseng; Sando, Sigrid Botne; Lauridsen, Camilla; Bråthen, Geir; White, Linda Rosemary; Salvesen, Øyvind; Aarsland, Dag; Hessen, Erik; Fladby, Tormod; Waterloo, Knut K; Scheffler, Katja (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-22)
      Importance Identification of proteins and genetic factors that reduce Alzheimer disease (AD) pathology is of importance when searching for novel AD treatments. Heterozygosity of the KL-VS haplotype has been associated with reduced amyloid and tau burden. Whether this association is mediated by the Klotho protein remains unclear. Objectives To assess concentrations of Klotho in cerebrospinal ...

    • Investigating the relationship between allocentric spatial working memory and biomarker status in preclinical and prodromal Alzheimer’s disease. 

      Lorentzen, Ingrid Myrvoll; Espenes, Johan Jacob; Eliassen, Ingvild Vøllo; Hessen, Erik; Waterloo, Knut K; Nakling, Arne Exner; Gisladottir, Berglind; Jarholm, Jonas Alexander; Fladby, Tormod; Kirsebom, Bjørn-Eivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-08)
      The 4 Mountain Test (4MT) is a test of allocentric spatial working memory and has been proposed as an earlier marker of predementia Alzheimer’s disease (AD) than episodic verbal memory. We here compare the 4MT to the CERAD word list memory recall in both cognitively normal (CN) and mild cognitive impairment (MCI) cases with or without cerebrospinal fluid markers (CSF) of Alzheimer’s disease ...

    • Regression-based normative data for the D-KEFS Color-Word Interference Test in Norwegian adults ages 20–85 

      Espenes, Johan Jacob; Lorentzen, Ingrid Myrvoll; Eliassen, Ingvild Vøllo; Hessen, Erik; Waterloo, Knut K; Timón, Santiago; Fladby, Tormod; Walhovd, Kristine Beate; Fjell, Anders Martin; Kirsebom, Bjørn-Eivind Seljelid (Journal article; Tidsskriftartikkel, 2023-11-16)
      <p><i>Objective:</i> The Delis-Kaplan Executive Function System (D-KEFS) Color-Word-Interference Test (CWIT; AKA Stroop test) is a widely used measure of processing speed and executive function. While test materials and instructions have been translated to Norwegian, only American age-adjusted norms from D-KEFS are available in Norway. We here develop norms in a sample of 1011 Norwegians between 20 ...

    • Regression‐based normative data for the Rey Auditory Verbal Learning Test in Norwegian and Swedish adults aged 49–79 and comparison with published norms 

      Espenes, Jacob; Eliassen, Ingvild Vøllo; Öhman, Fredrik; Hessen, Erik; Waterloo, Knut K; Eckerström, Marie; Lorentzen, Ingrid Myrvoll; Øien-Bergland, Cecilie; Niska, Madelene Halvari; Reina, Santiago Timon; Wallin, Anders; Fladby, Tormod; Kirsebom, Bjørn-Eivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-13)
      Objective: The Rey Auditory Verbal Learning Test (RAVLT) is a widely used measure of episodic verbal memory. To our knowledge, culturally adapted and demographically adjusted norms for the RAVLT are currently not available for Norwegian and Swedish adults, and imported North American norms are often used. We here develop regression-based norms for Norwegian and Swedish adults and compare our ...
