Well-Being and Health in RLS

Restless Legs Syndrome (RLS) is a condition associated with significant lifestyle changes. Researchers at Yale University are conducting a study that looks at health and well-being in patients with RLS. The researchers are looking to study primary RLS, which is RLS that occurs in the absence of diseases like Parkinson’s disease, multiple sclerosis, severe neuropathy, end-stage renal disease, schizophrenia, terminal cancer, and others. The study is a one-time online questionnaire that takes about 10–20 minutes to complete. You will not need to talk to anyone to complete this study, and your response is completely anonymous. There is no way for the researchers or anyone to determine your identity, even after you have completed the questionnaire.

Opioid Use to Treat RLS

Dr. John Winkelman is building an RLS Opioid Registry based at Massachusetts General Hospital with patients from across the United States to assess the long-term safety and effectiveness of opioid medications for RLS.

The RLS Opioid Registry will collect information from people who have been diagnosed with RLS and are taking a prescribed opioid as a treatment for symptom management. An initial brief phone interview will be followed by online surveys every 6 months for at least five years. Participants will be provided with a personal and full-sample summary of the data on a yearly basis. All data is stored anonymously in a secure electronic database.

Enrollment is limited to individuals who meet all the following criteria:

  • a diagnosis of RLS
  • are taking an opioid medication for RLS
  • have taken (or are currently taking) a dopamine agonist for RLS

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.
