About this study
This is a longitudinal study in healthy 1st degree relatives of patients with Parkinson's Disease (PD) carriers of a genetic mutation in genes that are known to increase the risk for PD. The purpose of this study is to explore the association between genetic mutations in the known genes and early preclinical symptoms such as motor, sensory, autonomic, behavioral and cognitive functions.

Questions about this trial
What is this clinical trial studying?
An observational study of Parkinson's Disease, run by Tel-Aviv Sourasky Medical Center at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 30 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Anat Mirelman, PhD (972-3-6974958, anatmi@tasmc.health.gov.il), or a site near the patient. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01502384, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Dec 2011.
