    • An observational study of compliance with the Scandinavian guidelines for management of minimal, mild and moderate head injury. 

      Heskestad, Ben Ottar; Waterloo, Knut; Ingebrigtsen, Tor; Romner, Bertil; Harr, Marianne Efskind; Helseth, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The Scandinavian guidelines for management of minimal, mild and moderate head injuries were developed to provide safe and cost effective assessment of head injured patients. In a previous study conducted one year after publication and implementation of the guidelines (2003), we showed low compliance, involving over-triage with computed tomography (CT) and hospital admissions. The aim of the present ...

      Background: Several studies have demonstrated the effect of guided Internet-based cognitive behavioral therapy (ICBT) for depression. However, ICBT is not suitable for all depressed patients and there is a considerable level of nonresponse. Research on predictors and moderators of outcome in ICBT is inconclusive. Objective: This paper explored predictors of response to an intervention combining the ...
    • Reduction in manual asymmetry and decline in fine manual dexterity in right-handed older adults with mild cognitive impairment 

      Vasylenko, Olena; Gorecka, Marta Maria; Waterloo, Knut; Rodríguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)
      Research in Parkinson’s or Alzheimer’s disease suggests that hand function is affected by neurodegenerative diseases. However, little is known about the relationship between hand function and mild cognitive impairment (MCI). Therefore, we conducted a kinematic analysis of unimanual hand movements in MCI patients to answer whether manual asymmetries and manual dexterity are affected or preserved ...
    • 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. ...
    • Regression-based norms for the FAS phonemic fluency test for ages 40–84 based on a Norwegian sample

      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. However, language and cultural differences impact performance on the FAS test, and using foreign norms may not be appropriate. Moreover, ...
    • The role of moderating variables on BOLD fMRI response during semantic verbal fluency and finger tapping in active and educated healthy seniors 

      Rodriguez-Aranda, Claudia; Castro-Chavira, Susana A; Espenes, Ragna; Barrios, Fernando A.; Waterloo, Knut; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
      Semantic verbal fluency is among the most employed tasks in cognitive aging research and substantial work is devoted to understanding the underlying mechanisms behind age-related differences at the neural and behavioral levels. The present investigation aimed to evaluate the role of moderating variables, such as age, sex, MMSE, and proxies of cognitive reserve (CR) on the hemodynamic response evoked ...
    • Screening for Alzheimer’s Disease: Cognitive Impairment in Self-Referred and Memory Clinic-Referred Patients 

      Kirsebom, Bjørn-Eivind; Espenes, Ragna; Waterloo, Knut; Hessen, Erik; Johnsen, Stein Harald; Bråthen, Geir; Aarsland, Dag; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-07)
      <p>Background</i>: Cognitive assessment is essential in tracking disease progression in AD. Presently, cohorts including preclinical at-risk participants are recruited by different means, which may bias cognitive and clinical features. We compared recruitment strategies to levels of cognitive functioning.<p> <p><i>Objective</i>: We investigate recruitment source biases in self-referred and ...
    • Stable cerebrospinal fluid neurogranin and β-site amyloid precursor protein cleaving enzyme 1 levels differentiate predementia Alzheimer's disease patients 

      Kirsebom, Bjørn-Eivind; Richter, Grit; Nordengen, Kaja; Aarsland, Dag; Bråthen, Geir; Tijms, Betty M; Visser, Pieter Jelle; Nilsson, Johanna; Selnes, Per; Kramberger, Milica G.; Winblad, Bengt; Waterloo, Knut; Gísladóttir, Berglind; Blennow, Kaj; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-24)
      Cerebrospinal fluid (CSF) β-site amyloid precursor protein cleaving enzyme 1 (BACE1), neurogranin and the neurogranin/BACE1 ratio are proposed markers for Alzheimer’s disease. BACE1 is also a drug target. However, CSF levels may differ between early-stage amyloid plaque formation (A) and later stage downstream tau-tangle pathology (T) and neurodegeneration (N) and may be expressed as an A/T/N stage ...

      Lillevoll, Kjersti; Vangberg, Hans Christian Bones; Griffiths, Kathleen; Waterloo, Knut; Eisemann, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Background Internet-based cognitive behavioural therapy (ICBT) is a promising approach to the prevention and reduction of depressive symptoms among adolescents. This study aimed to evaluate the feasibility and efficacy of disseminating a self-directed internet-based mental health intervention (MoodGYM) in senior high schools. It also sought to investigate possible effects of tailored and weekly ...
    • What does hand motor function tell us about our aging brain in association with WMH? 

      Riaz, Misbah; Vangberg, Torgil Riise; Vasylenko, Olena; Castro Chavira, Susana Angelica; Gorecka, Marta Maria; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-29)
      <i>Background</i> - White matter hyperintensities (WMH) are a common cerebral finding in older people. WMH are usually asymptomatic, but excessive WMH are associated with cognitive decline and dementia. WMH are also among the neurological findings most consistently associated with declining motor performance in healthy ageing.<br><br> <i>Aims</i> - To determine if WMH load is associated with ...
    • White matter correlates of gait perturbations resulting from spontaneous and lateralized attention in healthy older adults: A dual-task study 

      Castro Chavira, Susana Angelica; Vangberg, Torgil Riise; Gorecka, Marta Maria; Vasylenko, Olena; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-18)
      To date the neural mechanisms behind gait perturbations caused by dual-task paradigms are still unknown. Therefore, the present study examined white matter correlates of gait perturbations caused by a dichotic listening task where spontaneous (free focus of attention) and lateralized attentional control (voluntary attention directed to right or left-ear) were tested. Fifty-nine right-handed, healthy ...
