Beyond Alzheimer’s Disease: Can bilingualism be a more generalized protective factor in neurodegeneration?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)Bilingualism has been argued to have an impact on cognition and brain structure. Effects have been reported across the lifespan: from healthy children to ageing adults, including clinical (ageing) populations. It has been argued that active bilingualism may significantly contribute to the delaying of the expression of Alzheimer’s disease symptoms. If bilingualism plays an ameliorative role against ... -
Bilingualism is a long-term cognitively challenging experience that modulates metabolite concentrations in the healthy brain
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-29)Cognitively demanding experiences, including complex skills acquisition and processing, have been shown to induce brain adaptations, at least at the macroscopic level, e.g. on brain volume and/or functional connectivity. However, the neurobiological bases of these adaptations, including at the cellular level, are unclear and understudied. Here we use bilingualism as a case study to investigate the ... -
Brain structural correlates of autistic traits across the diagnostic divide: A grey matter and white matter microstructure study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-23)Autism Spectrum Disorders (ASD) are a set of neurodevelopmental conditions characterised by difficulties in social interaction and communication as well as stereotyped and restricted patterns of interest. Autistic traits exist in a continuum across the general population, whilst the extreme end of this distribution is diagnosed as clinical ASD. While many studies have investigated brain structure ... -
The effect of bilingualism on brain development from early childhood to young adulthood.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-20)Bilingualism afects the structure of the brain in adults, as evidenced by experience-dependent grey and white matter changes in brain structures implicated in language learning, processing, and control. However, limited evidence exists on how bilingualism may infuence brain development. We examined the developmental patterns of both grey and white matter structures in a cross-sectional study of ... -
The effects of bilingualism on hippocampal volume in ageing bilinguals

The effects of bilingualism on the structure of the hippocampus and its relationship to memory performance in ageing bilinguals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-05)Long-term management of more than one language has been argued to contribute to changes in brain and cognition. This has been particularly well documented in older age, where bilingualism has been linked to protective effects against neurocognitive decline. Since memory difficulties are key aspects of this decline, herein we examine potential effects of bilingualism on the hippocampus, a brain ... -
The Effects of Multilingualism on Brain Structure, Language Control and Language Processing
(Chapter; Bokkapittel, 2023-07-13)This chapter reviews a small but growing body of research that examines neuroplasticity stemming from multilingualism, specifically discussing some similarities and differences in brain structure and function stemming from in processing three or more languages, as a departure from bilingualism. The evidence comes from studies using magnetic resonance imaging to examine patterns of grey matter structure ... -
Evidence from Neurolinguistic Methodologies: Can it Actually Inform Linguistic/Language Acquisition Theories and Translate to Evidence-Based Applications?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-13)This special issue is a testament to the recent burgeoning interest by theoretical linguists, language acquisitionists and teaching practitioners in the neuroscience of language. It offers a highly valuable, state-of-the-art overview of the neurophysiological methods that are currently being applied to questions in the field of second language (L2) acquisition, teaching and processing. Research in ... -
Executive functions are modulated by the context of dual language use: diglossic, bilingual and monolingual older adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-27)Studies investigating the role of dual language use in modulating executive functions have reported mixed results, with some studies reporting benefits in older adults. These studies typically focus on bilingual settings, while the role of dual language use in diglossic settings is rarely investigated. In diglossia, the two language varieties are separated by context, making it an ideal test case ... -
Hippocampal adaptations in Mild Cognitive Impairment patients are modulated by bilingual language experiences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-24)Bilingualism has been shown to contribute to increased resilience against cognitive aging. One of the key brain structures linked to memory and dementia symptom onset, the hippocampus, has been observed to adapt in response to bilingual experience – at least in healthy individuals. However, in the context of neurodegenerative pathology, it is yet unclear what role previous bilingual experience ... -
Immersive bilingualism reshapes the core of the brain
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-27)Bilingualism has been shown to affect the structure of the brain, including cortical regions related to language. Less is known about subcortical structures, such as the basal ganglia, which underlie speech monitoring and language selection, processes that are crucial for bilinguals, as well as other linguistic functions, such as grammatical and phonological acquisition and processing. ... -
The Multilingual Picture Database
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-21)The growing interdisciplinary research feld of psycholinguistics is in constant need of new and up-to-date tools which will allow researchers to answer complex questions, but also expand on languages other than English, which dominates the feld. One type of such tools are picture datasets which provide naming norms for everyday objects. However, existing databases tend to be small in terms of ... -
Redefining bilingualism as a spectrum of experiences that differentially affects brain structure and function
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-26)Learning and using an additional language is shown to have an impact on the structure and function of the brain, including in regions involved in cognitive control and the connections between them. However, the available evidence remains variable in terms of the localization, extent, and trajectory of these effects. Variability likely stems from the fact that bilingualism has been routinely ...
