Outcome Measures

Primary Outcomes (1)

  • Study microbiome composition to explain the exact nature of the dysbiosis (microbial imbalance)

    The investigators anticipate confirming their prior findings that patients with PD have dysbiosis, and further identifying the nature of the dysbiosis including changes at the species and strain level.

    4 years

Secondary Outcomes (2)

  • Identify the potential contributing factors for dysbiosis in PD

    4 years

  • Determine how dysbiosis promotes PD

    4 years

Study Arms (2)

Cross-Sectional

This cohort is composed of only medicated PD subjects and their spouse or 1st degree relative.

Logitundinal

This cohort is composed of only non-medicated PD subjects and their spouse or first degree relative.

  • Are willing to participate in the study
  • Adults 40-80 years of age
  • No clinical evidence of neurological disorders including Parkinson's disease
  • Live in the same household as the Parkinson Disease patient or is a first degree relative of the PD patient or an independent healthy control
  • Are willing to participate in the study

  • Antibiotic use within last 12 weeks.
  • Use of probiotic supplement except yogurt.
  • Intentional change in diet.
  • Chronic use of NSAIDS. A washout period of 3 weeks is needed before the subject could be enrolled into the study. Low dose aspirin is allowed.
