I saw this the other day. Interesting observation, but they couldn't tell if this is a cause, an effect or simply a statistical fluke.

Correct. And the n was quite small.

PLMS in RLS patients causes blood pressure changes. Small n (only 10); author stated more studies need to be done. "Ahmed also notes this assessment is only the first step in understanding the link between sleep disorders and cardiovascular problems. He says, “We need more data and studies before we can conclude the clinical relevance and implications of sleep disorders on cardiovascular health.” "

Interesting...and makes me wonder how often neuropathy is comorbid with RLS as well as how often RLS may be mistaken for neuropathy.

I have at times over the years, had spells when there was burning on my feet. That just disappeared a few years ago. Nowadays I have times when there is a burning sensation on my lower legs usually just before the RLS symptoms break through.

Another link with cardiovascular health

"Poor sleep quality appears to be an important risk factor for atrial fibrillation, report scientists in the first study of its kind to demonstrate a relationship between poor sleep quality independent of sleep apnea and a higher risk of atrial fibrillation (AF). Their findings are published in HeartRhythm.

AF is an irregular, rapid heart rate that may cause symptoms such as heart palpitations, fatigue, and shortness of breath. It can substantially reduce quality of life and is associated with heightened risks of stroke, dementia, heart attack, kidney disease, and death. Obstructive sleep apnea has been established as a risk factor for AF, but the mechanism is unclear. While episodes of abnormally slow or shallow breathing (hypopnea) and apnea may cause cardiopulmonary stress, induce inflammation, and contribute to cardiovascular disease, obstructive sleep apnea also results in poor sleep. Aspects of poor sleep such as altered sleep duration, efficiency, and architecture have been linked to other cardiovascular diseases.

"While a relationship between sleep apnea and AF has previously been demonstrated, the effect of sleep itself on AF risk has remained unknown," explained lead investigator Gregory M. Marcus, MD, MAS, Electrophysiology Section, Division of Cardiology, Department of Medicine, University of California, San Francisco, CA, USA. "Strategies to enhance sleep quality are different from those that focus on relieving airway obstruction, so it is important to understand the relationship between sleep itself and AF."

Investigators drew on four different studies to determine whether poor sleep itself is a risk factor for AF. First, they used the global, internet-based Health eHeart Study and determined that individuals with more frequent nighttime awakenings while trying to sleep more often carried a diagnosis of AF. They then validated these findings by using the NIH-funded Cardiovascular Health Study, a prospective cohort study, in which they found that individuals who reported more frequent nighttime awakenings at baseline exhibited a higher risk of developing AF both before and after adjustment for potential confounders.

Within a subset of these individuals who had undergone formal sleep studies, they found that less REM sleep in particular predicted future AF. Finally, in order to see if these findings were readily translatable to patients already seen in healthcare settings and recognized by their providers as having sleeping difficulty, they drew on the California Healthcare Cost and Utilization Project (HCUP), a set of medical records databases of all California residents aged 21 or older who received care in a California ambulatory surgery unit, emergency department, or inpatient hospital unit between January 2005 and December 2009. Among several million people, the HCUP data confirmed that a diagnosis of insomnia predicted a diagnosis of AF both before and after adjustment for potential confounding effects.

These results provide more evidence that sleep quality is important to cardiovascular health and specifically to AF. Investigators determined that there was no evidence that sleep duration per se was a risk factor for AF. Instead, they consistently found sleep disruption to be an important risk factor. While the underlying mechanisms are still unknown, these findings may motivate novel ways to think about, and hence future research into, factors that influence AF risk.

This is the first study to demonstrate a relationship between worse sleep quality independent of sleep apnea and a higher risk of AF. "These data provide compelling evidence that sleep quality itself, even independent of sleep apnea, is an important determinant of AF risk," noted Dr. Marcus. "While there are several available treatments for AF, prevention of the disease would be ideal. The good news is that sleep quality can be modifiable and is something that at least to some degree is under the control of the individual. It's possible that improving sleep hygiene, such as performing regular exercise, getting to bed at a reasonable hour on a regular basis, and avoiding viewing screens before bed as well as caffeine later in the day, might help stave off AF.""

Another publication by Dr Ferre

The latest edition of Dr Ferre's work was published on July 26 in Neuroscientist. Unfortunately, the paper is not available to the general public, which is unfortunate because it is yet another excellent summary. This paper addresses some of the latest info about genetics and RLS. Many of the slides that Dr Ferre used in his webinar earlier this month are also included as figures in the paper.

This is a link to the abstract, but there isn't much meat to it compared to what was published in the full article. Hopefully it becomes available through another source.

This is a much needed and absolutely wonderful paper. It is well written, easy to understand and the recommendations are simple to implement. This should make it much easier for many RLS sufferers to get IV iron treatments.

Disappointing, as especially reading stjohnh's positive comments.

Betty, try it again. Something happened to the way the link was saved so that it did not catch the last few letters. I have fixed it now.

This is a link to an interview that was conducted with a doctor at Johns Hopkins about some of their recent work on the use of TNS to study RLS.
https://medicalresearch.com/sleep-disorders/insights-into-neurobiology-of-restless-legs-syndrome/44253/

In the paper that is cited in the interview, I cannot say that I understood everything, but there were several clear points that she did not cover in the interview that were very interesting. 1) the RLS subjects all had moderate to severe RLS, some with augmentation others without. 2) the measurements showed correlations with the severity of the subject's RLS. 3) the augmented subjects all showed results that were increased in the same way as RLS severity. 4) not everyone was able to tolerate the measurements, this included both those with RLS and controls.

Finally, all of the subjects in the test had been off of all medication for at least 14 days. I am not sure whether I could do that anymore. Another point that was made, which all of us would appreciate, a member of the research staff was present during the test to make certain that the subject did not close their eyes because there was a question of the results of some previous work as to whether the RLS subjects momentarily fell asleep due to sleep deprivation, even though the test apparently is rather uncomfortable.

I wish I could post a link to the paper, but the publisher is very protective of their copyright.
