Cerebrospinal fluid neurogranin/β-site APP-cleaving enzyme 1 predicts cognitive decline in preclinical Alzheimer's disease
Kirsebom, Bjørn-Eivind; Nordengen, Kaja; Selnes, Per; Waterloo, Knut; Torsetnes, Silje Bøen; Gisladottir, Berglind; Brix, Britta; Eugeen, Vanmechelen; Bråthen, Geir; Hessen, Erik; Aarsland, Dag; Fladby, Tormod (Journal article; Peer reviewed, 2018)Introduction The cerebrospinal fluid neurogranin (Ng)/β-site amyloid precursor protein-cleaving enzyme 1 (BACE1) ratio may reflect synaptic affection resulting from reduced beta-amyloid (Aβ) clearance. We hypothesize that ... -
Demographically adjusted CERAD wordlist test norms in a Norwegian sample from 40 to 80 years
Kirsebom, Bjørn-Eivind; Espenes, Ragna; Hessen, Erik; Waterloo, Knut; Johnsen, Stein Harald; Gundersen, Elisabeth; Sando, Sigrid Botne; Grøntvedt, Gøril Rolfseng; Timón, Santiago; Fladby, Tormod (Journal article; Peer reviewed, 2019)Background/Objective: In recent years, several slightly younger cohorts have been established in order to study the preclinical and prodromal phases of dementia. The Consortium to Establish a Registry for Alzheimer’s Disease ... -
Demographically adjusted trail making test norms in a Scandinavian sample from 41 to 84 years
Espenes, Johan Jacob; Hessen, Erik; Eliassen, Ingvild Vøllo; Waterloo, Knut; Eckerström, Marie; Sando, Sigrid Botne; Timón, Santiago; Wallin, Anders; Fladby, Tormod; Kirsebom, Bjørn-Eivind (Peer reviewed; Journal article, 2020)Objective 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. ... -
In Brief Neuropsychological Assessment, Amnestic Mild Cognitive Impairment (MCI) Is associated with Cerebrospinal Fluid Biomarkers for Cognitive Decline in Contrast to the Prevailing NIA-AA MCI Criterion
Hessen, Erik; Kirsebom, Bjørn-Eivind; Eriksson, Cecilia Magdalena; Eliassen, Carl Fredrik Andestad; Nakling, Arne; Bråthen, Geir; Waterloo, Knut; Aarsland, Dag; Fladby, Tormod (Journal article; Peer reviewed, 2019)Background: In the care of persons with cognitive problems, it is important to use a valid mild cognitive impairment (MCI) criterion that discriminates well between normal and pathological aging. Objective: To find ... -
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 (Peer reviewed; Journal article, 2023)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 ... -
Predictive and diagnostic utility of brief neuropsychological assessment in detecting Alzheimer's pathology and progression to dementia
Eliassen, Ingvild Vøllo; Fladby, Tormod; Kirsebom, Bjørn-Eivind; Waterloo, Knut; Eckerström, Marie; Wallin, Anders; Bråthen, Geir; Aarsland, Dag; Hessen, Erik (Peer reviewed; Journal article, 2020)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) ... -

Background: Practice effects are common in repeated ... -
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; Peer reviewed, 2021)The FAS phonemic fluency test is a commonly used neuropsychological test of executive function and processing speed.
