Overview
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.
Detailed description
The purpose of this study is to use a brain imaging method called PIB PET and 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. The investigators will be including both PD and normal subjects in this study. This a long term study and we are considering including a total of 320 participants in this protocol.
Interventions
- 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.
Primary outcome measures
- Investigations of Dementia in Parkinsons Disease [Time frame: 2030]
Eligibility criteria
Inclusion criteria
- 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.
Exclusion criteria
- 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.
