The prevalence of Parkinson disease (PD), with and without dementia, increases with age and is higher in men than women, according to a recent study. Furthermore, researchers project that the number of persons with PD in the US will increase substantially by 2060. They used the Rochester Epidemiology Project medical records-linkage system to identify all persons with PD, with or without dementia, residing in Olmsted County, MN on January 1, 2006. A movement disorders specialist reviewed the complete medical records of each person to confirm the presence of PD. They found:
- There were 296 persons with PD, with and without dementia, on the prevalence date (187 men, 109 women); the overall prevalence increased with age from 0.01% (30-39 years) to 2.83% (≥90 years).
- The prevalence of PD without dementia increased with age from 0.01% (30-39 years) to 1.25% (≥90 years).
- The prevalence of PD with dementia increased with age from 0.10% (60-69 years) to 1.59% (≥90 years).
- The prevalence was higher in men than in women for all subtypes and all age groups.
