## Abstract We sought to determine the relative risk (RR) of Parkinson's disease (PD) for having a firstβdegree relative with PD versus having no firstβdegree relative with PD. Studies of familial aggregation of PD were identified by searching Medline and other sources. From each study, RRs were ex

## Abstract Data on the familial aggregation of Parkinson's disease (PD) remain conflicting. We conducted a historical cohort study of 1,001 firstβdegree relatives of 162 probands with PD and of 851 relatives of 147 control probands representative of the population of Olmsted County, Minnesota (fro
## Abstract Dementia is common in patients with Parkinson's disease (PDD). The etiology of PDD is still unclear, but exciting advances have been made in discovering pathogenetic components in Parkinson's disease (PD), implicating the role of genetic factors. It is, however, still controversial whet
The role of heredity in early- versus late-onset Parkinson's disease (PD) is controversial. We estimated the degree of increased risk of PD in first-degree relatives of 221 PD probands with age of onset 50 years or younger and 266 PD probands with age of onset older than 50 years compared with the f
## Abstract To assess the familial aggregation of Parkinson's disease (PD), we compared the cumulative incidence of PD among firstβdegree relatives of PD cases and controls. We identified newly diagnosed patients with PD (n = 573) during 1994 to 1995 within Kaiser Permanente Medical Care Program of
