  • Simplified description (AI rewritten)
  • Technical description (Original)

This study looks at impulsivity (acting quickly without thinking) in people with a sleep disorder called idiopathic REM Sleep Behavior Disorder (iRBD), which might be an early stage of Parkinson's Disease (PD). Researchers want to see if there are changes in the brain's structure and activity in people with iRBD by using a special scan called an fMRI (functional Magnetic Resonance Imaging) when they do tasks that test impulsivity. The study will compare healthy people, people with iRBD, and people with PD.

  • The study needs 96 participants (24 in each group) who will undergo brain scans.
  • Participants should not have a history of Parkinson's or other similar conditions.
  • Those with mood disorders or certain medical implants cannot join.

The study aims to help understand brain changes in impulsivity and could help detect early signs of PD. Participants will be asked to perform impulsivity tasks and may undergo MRI scans. If you're interested, make sure you fit the criteria and are okay with the procedures involved.

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.
