Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This single site study, is enrolling Parkinson disease (PD) patients and their family members and is limited to participants of Ashkenazi (Eastern European) Jewish descent with GBA and LRRK2 mutations, or with 3 or more family members with PD. Follow-up will be for three years. Participants must be in the New York City area yearly and willing to come to Mount Sinai Downtown for yearly 2 hour study visits which include obtaining personal medical and family history information, blood, urine and spinal fluid samples, neurological exam and neuropsychiatric testing. De-identified data and samples will be securely stored at a central NIH-run repository for access by other researchers. Spinal fluid collection is encouraged but optional.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Parkinson disease patients and their family members who are of Ashkenazi (Eastern European) Jewish descent who either have a GBA or LRRK2 mutations or who have 3 or more family members with PD.

Description

Inclusion Criteria:

  • Parkinson disease patients and their family members and is limited to participants of Ashkenazi (Eastern European) Jewish descent with GBA and LRRK2 mutations, or with 3 or more family members with PD
  • Participants must be local to the New York City area and willing to come to Mount Sinai Downtown for annual 2 hour study visits which include obtaining personal medical and family history information, blood, urine and spinal fluid samples, neurological exam and neuropsychiatric testing. Spinal fluid collection is encouraged but optional.

Exclusion Criteria:

-Patients who do not have Parkinson disease or family members of Ashkenazi (Eastern European) Jewish descent who either has a GBA or LRRK2 mutations OR who has 3 or more family members with PD.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2019

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
April 1, 2025

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
