In earlier studies, we found high age‐adjusted prevalences of Parkinson's disease (PD) in the Faroe Islands (209 per 100,000 inhabitants) and in Greenland (187.5 per 100,000 inhabitants) compared to the age‐adjusted prevalence on the island of Als in the southern part of Denmark (98.3 per 100,000 inhabitants). We thoroughly examined patients with suspected parkinsonism using internationally accepted diagnostic criteria. In the present study, we found no significant clinical differences between patients with PD in the three areas, despite this high difference in prevalence. However, comparing the age at examination and age at treatment, the patients were younger in Greenland, a higher proportion of patients had cognitive decline, and they had a higher mean Hoehn and Yahr rating score, although they received a lower levodopa dose. A higher proportion of the patients in Greenland were newly diagnosed than in the other two areas. © 2004 Movement Disorder Society
