    Perceived occupational gaps one year after stroke: An explorative study2011In: Journal of Rehabilitation Medicine, ISSN 1651-2081, Vol. 44, no 1, p. 36-42Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To explore and describe factors associated with occupational gaps and to identify factors at 3 months that predict occupational gaps one year post-stroke. A gap, a restriction in participation, is considered to be present when there is a discrepancy between what the individual wants to do and what they actually do in everyday life. DESIGN: Prospective longitudinal study. SUBJECTS: Two hundred persons with stroke. METHODS: Data from the Occupational Gaps Questionnaire, one year post-stroke, was used as the dependent variable in 3- and 12-month regression analyses. Domains of the Stroke Impact Scale, global life satisfaction, demographic and medical factors were used as independent variables. RESULTS: At 3 months, activities of daily living abilities, social participation and not being born in Sweden predicted occupational gaps at 12 months. Stroke severity and not being born in Sweden and 3 factors at 12 months: social participation, self-rated recovery, and global life satisfaction were associated with occupational gaps. CONCLUSION: Activities of daily living ability at 3 months predicted occupational gaps after stroke. Thus, it is possible to identify early on, and provide interventions for, those that risk participation restrictions. Not being born in the country might be an indicator of a risk for participation restrictions.

    Dual-task performance and neurodegeneration: Correlations between timed up-and-go dual-task test outcomes and Alzheimer's disease cerebrospinal fluid biomarkers2019In: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Tools to identify individuals at preclinical stages of dementia disorders are needed to enable early interventions. Alterations in dual-task performance have been detected early in progressive neurodegenerative disorders. Hence, dual-task testing may have the potential to screen for cognitive impairment caused by neurodegeneration. Exploring correlations between dual-task performance and biomarkers of neurodegeneration is therefore of interest.

    OBJECTIVE: To investigate correlations between Timed Up-and-Go dual-task (TUGdt) outcomes and Alzheimer's disease (AD) cerebrospinal fluid (CSF) biomarkers amyloid-β 42 (Aβ42), total tau (t-tau), and phosphorylated tau (p-tau).

    METHODS: This cross-sectional cohort study included 90 participants (age range 49-84 years) undergoing memory assessment, who were subsequently diagnosed with AD, other dementia disorders, mild cognitive impairment, or subjective cognitive impairment. TUG combined with "Naming Animals" (TUGdt NA) and "Months Backwards" (TUGdt MB), respectively, were used to assess dual-task performance. The number of correct words and time taken to complete the tests were measured. The CSF biomarkers were analysed by ELISA. Spearman's rank correlation was used for analyses between TUGdt outcomes (TUGdt NA and TUGdt MB), and CSF biomarkers, adjusted for age, gender, and educational level.

    RESULTS: The number of correct words, as well as the number of correct words/10 s during TUGdt NA correlated negatively to CSF t-tau and p-tau. No correlations were found between any time scores and CSF biomarkers.

    CONCLUSION: The correlations between TUGdt NA and t-tau and p-tau may indicate that neurodegeneration affects dual-task performance. Longitudinal studies are needed to further explore dual-task testing in screening for cognitive impairment due to neurodegeneration.
