About

Prospective observational study of Parkinson's disease with repeat clinical assessment and biobanking of blood samples.

Full description

To identify genetic and biomarker factors which affect the expression of Parkinson's Disease.

Primary objective: To define the severity and rates of progression of clinical features of Parkinson's Disease.

Secondary objective: To relate clinical phenomenology of Parkinson's disease to genetic and biomarker changes.

Enrollment: 2,614 patients

Sex: All

Ages: 18 to 90 years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

A. Parkinson's Disease patients

Inclusion criteria

2. Age ≥18 to <90years
3. Subject is able and willing to provided informed consent.

Exclusion criteria

1. Patient has severe comorbid illness that would prevent full study participation
2. Patient has features indicating another type of degenerative parkinsonism, e.g. progressive supranuclear palsy
3. Drug-induced parkinsonism (Drug-unmasked PD is allowed)
4. Symmetrical lower body parkinsonism attributable to significant cortical and/or subcortical cerebrovascular disease (patients with 'incidental' small vessel disease on brain imaging are allowed).
5. Negative or normal functional imaging of the presynaptic dopamine system
6. The presence of UK Brain Bank exclusion criteria will be recorded at baseline, allowing for the presence of 1 or 2 exclusion criteria (e.g. dopamine antagonist Drug used; more than one affected relative) (if justified e.g. by abnormal SPECT).

3. Subject is able and willing to provided informed consent.

Exclusion criteria

1. Subject has severe comorbid illness that would prevent study participation
2. Subject already has a diagnosis of Parkinson's disease
