We have conducted a hospital-based survey of the age-specific prevalence of Parkinson's disease in 551 patients from Helsinki and Vancouver. We conclude that the disorder may be starting earlier than previously and we discuss the implications of this finding for the etiology of Parkinson's disease.
我们对来自赫尔辛基和温哥华的551名患者进行了一项基于医院的帕金森病年龄别患病率调查。我们得出结论,该疾病的发病可能比以前更早开始,并且我们讨论了这一发现对帕金森病病因学的意义。
