      Introduction The Rey–Osterrieth Complex Figure Test (RCFT) is one of the most commonly used neuropsychological tests in Sweden and Norway. However, no publications provide normative data for this population. The objective of this study was to present demographically adjusted norms for a Swedish and Norwegian population and to evaluate these in an independent comparison group.<p> <p>Methods The ...

      <i>Objective</i> - The trail making test (TMT) is one of the most widely used neuropsychological tests. TMT-A provides measures of visual scanning/visuomotor speed and TMT-B involves additional demands on executive functions. Derived scores TMT B-A and TMT B/A enhance measures of executive functioning. However, simple B-A subtraction may lead to false estimates of executive dysfunction in clinical ...
    • Investigating the relationship between allocentric spatial working memory and biomarker status in preclinical and prodromal Alzheimer’s disease.

      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 ...
    • Predictive and diagnostic utility of brief neuropsychological assessment in detecting Alzheimer's pathology and progression to dementia

      Objective: To assess the role of brief neuropsychological assessments in prediction and identification of Alzheimer’s disease (AD) pathology and progression to AD dementia. Method: Adults (N = 255; range = 40–81 years) with self-reported cognitive decline underwent baseline and 2-year follow-up clinical assessment, including a brief neuropsychological screening and lumbar puncture. Five different ...
    • Regression-based normative data for the D-KEFS Color-Word Interference Test in Norwegian adults ages 20–85

      <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 ...
