Dementia Incidence in Individuals With Parkinson's Disease in the Framingham Heart Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Limited information exists on incident dementia in individuals with Parkinson's disease (PD) in US community‐based samples. We examined cognitive statuses and PD diagnoses of 183 individuals in the Framingham Heart Study (FHS) to establish incident dementia, mortality rates, associations with sex, age at PD onset, and education level.
