Cross-cultural neuropsychological assessment in Europe: Position statement of the European Consortium on Cross-Cultural Neuropsychology (ECCroN)

Over the past decades European societies have become increasingly diverse. This diversity in culture, education, and language significantly impacts neuropsychological assessment. Although several initiatives are under way to overcome these barriers - e.g. newly developed and validated test batteries - there is a need for more collaboration in the development and implementation of neuropsychological tests, such as in the domains of social cognition and language. To address these gaps in cross-cultural neuropsychological assessment in Europe, the European Consortium on Cross-Cultural Neuropsychology (ECCroN) was established in 2019. ECCroN recommends taking a broad range of variables into account, such as linguistic factors, literacy, education, migration history, acculturation and other cultural factors. We advocate against race-based norms as a solution to the challenging interpretation of group differences on neuropsychological tests, and instead support the development, validation, and standardization of more widely applicable/cross-culturally applicable tests that take into account interindividual variability. Last, ECCroN advocates for an improvement in the clinical training of neuropsychologists in culturally sensitive neuropsychological assessment, and the development and implementation of guidelines for interpreter-mediated neuropsychological assessment in diverse populations in Europe. ECCroN may impact research and clinical practice by contributing to existing theoretical frameworks and by improving the assessment of diverse individuals across Europe through collaborations on test development, collection of normative data, cross-cultural clinical training, and interpreter-mediated assessment

Cognitive rehabilitation for Parkinson's disease dementia: study protocol for a randomized controlled trial

This is the final version of the article. Available from the publisher via the DOI in this record.The erratum to this article is available in ORE at http://hdl.handle.net/10871/40744There is growing interest in developing non-pharmacological treatments to address the cognitive deficits apparent in Parkinson’s disease dementia and dementia with Lewy bodies. Cognitive rehabilitation is a goal-oriented behavioural intervention which focuses on improving everyday functioning through management of cognitive difficulties; it has been shown to be effective in Alzheimer’s disease. To date, no studies have assessed its potential efficacy for addressing the impact of cognitive impairment in people with Parkinson’s disease or dementia with Lewy bodies. Methods/design Participants (n = 45) will be recruited from movement disorders, care for the elderly and memory clinics. Inclusion criteria include: a diagnosis of Parkinson’s disease, Parkinson’s disease dementia or dementia with Lewy bodies according to consensus criteria and an Addenbrooke’s Cognitive Examination – III score of ≤ 82. Exclusion criteria include: a diagnosis of any other significant neurological condition; major psychiatric disorder, including depression, which is not related to the patient’s Parkinson’s disease and unstable medication use for their physical or cognitive symptoms. A single-blind pilot randomised controlled trial, with concurrent economic evaluation, will compare the relative efficacy of cognitive rehabilitation with that of two control conditions. Following a goal-setting interview, the participants will be randomised to one of the three study arms: cognitive rehabilitation (eight weekly sessions), relaxation therapy (eight weekly sessions) or treatment as usual. Randomisation and treatment group allocation will be carried out by a clinical trials unit using a dynamic adaptive sequential randomisation algorithm. The primary outcomes are patients’ perceived goal attainment at a 2-months post-intervention assessment and a 6-months follow-up. Secondary outcomes include patients’ objective cognitive performance (on tests of memory and executive function) and satisfaction with goal attainment, carers’ perception of patients’ goal attainment and patients’ and carers’ health status and psychosocial well-being, measured at the same time points. Cost-effectiveness will be examined to explore the design of a larger cost-effectiveness analysis alongside a full trial. Discussion This pilot study will evaluate the application of cognitive rehabilitation for the management of cognitive difficulties associated with Parkinson’s disease dementia and dementia with Lewy bodies. The results of the study will inform the design of a fully powered randomised controlled trial.This work is supported by the National Institute for Social Care and Health Research (grant number RFPPB-2042-1020).
