Parkinson's Disease and Sudden Unexpected Death

We read with interest the excellent article by Seo and colleagues reporting a 10-year relative survival rate of patients with Parkinson's disease using a nationwide database.1 It was clearly demonstrated that individuals with this disease have a lower survival rate than the general population even during the early stages of the disease.1 Thus, the authors appropriately suggest that improvements in clinical practice and detection of pertinent causes of death may be useful in preventing premature death among patients with Parkinson's disease.
