Overview

The study aims to observe changes in dopaminergic genes expression in peripheral tissue upon prolonged dopamine agonist treatment on patients with Restless Legs Syndrome (RLS). Similar studies in Parkinson's disease have shown changes in alpha-synuclein expression, which might offer insights into the dopaminergic gene regulation seen in RLS. The dopamine agonist drugs to be included in this study are: Pramipexole (Mirapex), Ropinirole (Requip), Rotigotine (Neupro), Apomorphine (Apokyn), Bromocriptine (Parlodel). Specifically, the study will collect nasal swabs of participants partitioned into two groups, those who have not used a dopamine agonist or been on a dopamine agonist for less than 1 month compared to those who have been on the medication for 6 or more months. This research could provide insight into changes in dopaminergic gene expression associated with Augmentation Syndrome (AS) which occurs after long term dopamine agonist treatment in RLS patients.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
