Hormones and Their Role in Restless Legs Syndrome

We need YOUR HELP RLS Community!! We have received funding from the Department of Defense to continue our study of hormones in RLS. This means that we are able to reimburse you for the COST OF YOUR TRAVEL (up to $600) as our research requires a one-time visit to New Haven, Connecticut. Our research aims to uncover the underlying biological mechanisms of RLS. Doing this is essential in order to develop new more effective treatments for RLS and to discover a cure.

Brian Koo, MD and his team at Yale University are conducting research to determine whether levels of specific hormones are increased in the blood and spinal fluid of persons with RLS. The research requires that participants undergo blood draws and a spinal tap.

We are looking for individuals with moderate to severe primary idiopathic RLS who do not have other disorders such as kidney disease, multiple sclerosis, Parkinson disease, or severe neuropathy AND who are not currently taking medicine for RLS. If you are taking medicine for RLS, you can discuss with Dr. Koo about temporarily coming off of your medicine. We know that coming off your medicine, even temporarily, and undergoing a spinal tap are a lot to ask, but this research is important and we need YOUR HELP!!

If you believe you are eligible or have any questions about the research, please contact our study team led by Dr. Brian Koo, MD.

If you live in the New York City area, you may be eligible to participate in a new research opportunity.

We are conducting a research study to determine whether there are changes in the retinal structure of the eyes of individuals with Restless Legs Syndrome, also known as Willis-Ekbom Disease (WED/RLS) compared to individuals with Parkinson’s disease, multiple system atrophy, and healthy controls.

The study will take place at the New York University Langone Medical Center and will require one visit, lasting approximately 1-2 hours. The visit will include an initial screening and an eye exam. You will be asked to sit comfortably and to place your chin in a chin rest and to look into a machine that will take pictures of your optic nerve. The eye examination will take approximately 15 minutes and you will not feel anything while the machine takes pictures of your retina (the back of your eye).

There is no direct benefit to you or expense reimbursement available from your participation in the study. It is hoped that the knowledge gained will be of benefit to others in the future. Studies done for this research study are not a part of your regular medical care and will not be included in your medical record.

If interested, please contact Dr. Jose Martinez at
