Introduction:
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.
Objective:
Since preliminary data suggest considerable PD underdiagnosis, 69%, 67%, 52%, 29%, we studied potential differences of PD prevalences in Spain.
Material And Methods:
We obtained age-specific prevalences of PD from scientific media and publications from professional meetings and compared them using stratified analysis.
Results:
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.
Conclusion:
PD might be considerably underdiagnosed in Spain.
