RECRUITINGOBSERVATIONAL
Investigations of Dementia in Parkinson Disease
About This Trial
The purpose of this study is to use a brain imaging method called Pittsburgh B (PIB) Positron Emission Tomography (PET) and Vesicular Cholinergic Transport (VAT) PET to determine dementia subtypes in patients with Parkinson disease (PD). The ultimate goal of this project is to be able to identify individuals with PD who are at risk of developing dementia, and to distinguish the underlying cause of dementia.
Who May Be Eligible (Plain English)
Who May Qualify:
- PD patients must exhibit three of the following cardinal signs: rest tremor, rigidity, bradykinesia, or postural instability; or two of these features with one of the first three displaying asymmetry.
Who Should NOT Join This Trial:
- history of head trauma, major neurological or psychiatric diseases other than Parkinson disease and dementia, e.g. stroke, multiple sclerosis, depression or schizophrenia.
- severe systemic diseases.
- inability to lie still for 90 minutes.
- metallic implants, pacemakers, or any other contraindication to MRI.
- refusal to consent to brain donation.
Always talk to your doctor about whether this trial is right for you.

RADIATION
PiB and VAT
There is no intervention for this study. The PiB and VAT are used during the PET procedures to help to identify any excessive abnormal proteins in the brain.
