Apolipoprotein E gene alleles have been linked to various cardiovascular and neurodegenerative disorders. There have been conflicting reports of associations between Apolipoprotein E alleles and Parkinson disease and Parkinson disease dementia. To investigate the role of Apolipoprotein E alleles in Parkinson disease and Parkinson disease dementia, we have determined Apolipoprotein E genotypes in a group of patients with Parkinson disease (n = 95) and compared them with those of healthy control participants (n = 73). Additionally, in 64 longitudinally followed patients with Parkinson disease, the allele types were correlated to development and progression of dementia and to time from onset of Parkinson disease to dementia using multivariate and survival analyses. The Apolipoprotein E epsilon 4 epsilon 4 genotype was more common in patients with Parkinson disease (7.4%) than in healthy controls (1.4%; P = .03). No significant associations between the Apolipoprotein E genotype and development and progression of dementia or time to dementia were found. More studies with larger Parkinson disease samples are warranted.
