It is unclear if differences exist in these subjective elements between Parkinson’s disease (PD) patients born in Canada, the United Kingdom and the United States (Anglosphere group) versus immigrant patients born elsewhere (International group). Participants and Methods: We conducted a retrospective chart review of advanced PD patients (n=764) assessed in Toronto, Canada. 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 slightly more executive and language SCD during the interview but International care-partners reported more 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 were small, and persisted after controlling for depression severity in the International group. Conclusions: 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, unlike large effects found on some performance-based measures, and they should be given significant weight when diagnosing cognitive dysfunction in PD.

Objective:

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. It is unclear if differences exist in these subjective elements between Parkinson’s disease (PD) patients born in Canada, the United Kingdom and the United States (Anglosphere group) versus immigrant patients born elsewhere (International group).

Participants and Methods:

We conducted a retrospective chart review of advanced PD patients (n=764) assessed in Toronto, Canada. 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 slightly more executive and language SCD during the interview but International care-partners reported more 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 were small, and persisted after controlling for depression severity in the International group.

Conclusions:

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, unlike large effects found on some performance-based measures, and they should be given significant weight when diagnosing cognitive dysfunction in PD.
