      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 ...
    • The impact of age-related hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during dual-tasking among community dwelling older adults 

      Gorecka, Marta Maria; Vasylenko, Olena; Espenes, Johan Jacob; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-27)
      This investigation assessed the impact of hearing loss and lateralized auditory attention on spatiotemporal parameters of gait during overground dual-tasking by the use of the dichotic listening task. Seventy-eight right-handed, healthy older adults between 60 and 88 years were assigned to a Young-Old (<70 years) or an Old-Old (>71 years) group. Cognitive assessment and pure tone audiometry were ...
    • 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

      <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 norms for the FAS phonemic fluency test for ages 40–84 based on a Norwegian sample 

      Lorentzen, Ingrid Myrvoll; Espenes, Johan Jacob; Hessen, Erik; Waterloo, Knut; Bråthen, Geir; Timón, Santiago; Aarsland, Dag; Fladby, Tormod; Kirsebom, Bjørn-Eivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-08)
      <p>The FAS phonemic fluency test is a commonly used neuropsychological test of executive function and processing speed. Although Norwegian discrete norms have been developed for the FAS test, American regression-based norms are frequently used by clinicians in Norway. <p>However, language and cultural differences impact performance on the FAS test, and using foreign norms may not be appropriate. ...
