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

Condition or disease
Parkinson's Disease

Detailed 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.

Recent diagnosis (P3)
Primary cohort; participants recruited if diagnosed within the last three years
Early diagnosis (P50)
Participants recruited if diagnosed before the age of 50 years old
Relatives (R)
Siblings of existing participants

Primary Outcome Measures :
  1. Proportion of participants with Parkinson's who have gene mutations and variations [ Time Frame: Up to 36 months ]
    Genotyping for leucine rich repeat kinase 2 (LRRK2), Glucocerebrosidase (GBA) (all cases) and Parkin, Phosphatase and tensin homolog-induced putative kinase 1 (PINK1)(onset<50years)

Secondary Outcome Measures :
  1. Categorisation of subtypes of Parkinson's using cluster analysis [ Time Frame: At 4 years ]

    Clustering of motor and non-motor features measured using Movement Disorder Society Unified Parkinson's disease rating scale (MDS-UPDRS), Montréal cognitive assessment (MoCA), Non-motor symptom Scale (NMSS), Scale for outcomes in Parkinson's autonomic (SCOPA-AUT), Olfaction testing using University of Pennsylvania Smell Identification Test (UPSIT) or Sniffin' sticks, and Leeds anxiety and depression scale (LADS).

    This will use sequential factor analysis of the results of the above assessments, followed established methods, firstly exploratory factor analysis and secondly confirmatory factor analysis. Factor scores and other clinically important variables will then be combined to construct a single dataset for carrying out the cluster analysis. Hierarchical clustering will then be applied, and models with between 2 and 5 clusters will be described and compared.

  2. Proportion of cases with Parkinson's who have vascular comorbidity and risk factors [ Time Frame: At 4 years ]
    Prior history of vascular events, or calculated using Quantification of Risk version 2 (QRISK2) vascular risk score

Study Population
Parkinson's Disease defined by UK Brain Bank criteria Siblings of cases of Parkinson's disease

A. Parkinson's Disease patients

Inclusion criteria

  1. Diagnosis of Parkinson's disease, based on UK Brain Bank criteria and made within the preceding 3 years ('recent onset cases') or diagnosed at under 50 years ('under 50 years cases')
  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).

B. First degree relatives Inclusion criteria

  1. Age ≥18 to < 90years
  2. Resident in the United Kingdom and able to access one of the PRoBaND study centres.
  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
