Abstract

AbstractObjective:Subjective cognitive decline (SCD) and how much cognitive decline impacts one’s ability to perform instrumental activities of daily living (iADLs) are necessary elements of neuropsychological assessment when diagnosing mild cognitive impairment (MCI) and dementia. Though limited, the literature suggests that culture and self-appraisal of cognitive abilities are related. However, it is unclear if differences exist in the subjective elements of neuropsychological assessments between patients born in Anglosphere countries (Canada, the USA, and the UK) versus immigrants born elsewhere (International Group).Method:We conducted a retrospective chart review of advanced Parkinson’s disease (PD) patients (n = 764). Reports of SCD and iADL difficulties were extracted from neuropsychological reports and coded by two independent raters. We also examined responses on self- and family-rated questionnaires of executive functioning and iADL difficulties.Results:Anglosphere and International patients did not differ on overall, memory, or attention SCD, or overall iADL difficulties based on interviews. Anglosphere patients reported more executive and language SCD during the interview but International care-partners reported more current executive dysfunction on a questionnaire. International patients and care-partners reported more iADL difficulties on a questionnaire, which they ascribed to motor (not cognitive) symptoms. The effects on questionnaires were small and persisted after accounting for depression severity ratings.Conclusion:There were no consistent group differences in the number or pervasiveness of SCD or iADL difficulties reported by Anglosphere versus International groups. Immigration status has limited effect on these subjective elements and they should be given significant weight when diagnosing cognitive dysfunction in PD.
