Parkinson's disease (PD) has been found in all surveys focusing on frequent neurological disorders. In general, sparse geographical variation of PD prevalence was found.
Since preliminary data suggest considerable PD underdiagnosis, 69%, 67%, 52%, 29%, we studied potential differences of PD prevalences in Spain.
We obtained age-specific prevalences of PD from scientific media and publications from professional meetings and compared them using stratified analysis.
The geographical variation of prevalences at ages 60-89 years was small except among those aged 80-89, being twofold in Cantalejo, Segovia, and approximately 1/3 in Lower Aragón, Teruel. The Cantalejo (door-to-door, 67% de novo diagnoses) versus Lower Aragón (medical services) prevalence ratio was 4/1.
PD might be considerably underdiagnosed in Spain.
在所有针对常见神经系统疾病的调查中均发现了帕金森病（PD）。总体而言，PD患病率的地理差异较小。
由于初步数据显示PD存在相当程度的漏诊，比例分别为69%、67%、52%、29%，我们研究了西班牙PD患病率的潜在差异。
我们从科学媒体以及专业会议的出版物中获取了特定年龄的PD患病率，并采用分层分析进行比较。
60 - 89岁年龄段患病率的地理差异较小，但80 - 89岁人群除外，在塞哥维亚的坎塔莱霍患病率是其他地区的两倍，而在特鲁埃尔省的下阿拉贡患病率约为其他地区的1/3。坎塔莱霍（逐户调查，67%为新发诊断）与下阿拉贡（医疗服务数据）的患病率之比为4/1。
在西班牙，PD可能存在相当程度的漏诊。
