Why not. That's what I always thought. There has to be something similar going on to generate similar symptoms. Not everyone who has anemia gets WED/RLS.

Re: Published Research - Suicide and RLS (WED)

Here is another publication that is pending, this time a study of the relationship between suicide and RLS. The results summary so far says

192 RLS and 158 control participants were comparable for age, sex, race, and other potential demographic confounders. In general, RLS was moderate-to-severe (mean IRLSS 26.4±7.5). Significantly more RLS than control participants had lifetime suicidal ideation or behavior (27.1% vs. 7.0%; p<0.00001) or lifetime depression history (65.6%% vs. 22.8%; p<0.00001). The odds of having a lifetime suicidal ideation or behavior was higher in those with RLS (2.80 [1.29,6.11]), even after accounting for depression and other confounders. In RLS, the odds of lifetime suicidal ideation or behavior was increased if there was lifetime depression (7.37 [2.65,20.47]) or if RLS in the past was severe or very severe (2.36 [1.03,5.40]).

Iron deficiency in the mitochondria of white blood cells (and other body cells???) in RLS/WED!

Association of mitochondrial iron deficiency and dysfunction with idiopathic restless legs syndrome Movement Disorders, 11 October 2018 https://doi.org/10.1002/mds.27482

ABSTRACT
Background: Restless legs syndrome is a sensorimotor neurological disorder of the limbs that impairs quality of life and disturbs sleep. However, there has been progress in understanding the disease involving the dopaminergic system as well as iron metabolism. The exact pathophysiological mechanisms of restless legs syndrome remain elusive. We tried to elucidate the underlying mechanisms in iron metabolism in restless legs syndrome subjects on a systemic, cellular, and mitochondrial level.

Methods: We conducted a study prospectively recruiting 168 restless legs syndrome patients and 119 age‐matched healthy controls focusing on iron metabolism using human monocytes as surrogates.

Results: Evaluation of systemic iron metabolism parameters in the circulation showed no significant difference between patients and controls. We observed a significant reduction in mRNA levels of heme oxygenase 1 and mitochondrial iron genes like mitoferrin 1 and 2 in monocytes isolated from restless legs syndrome patients, indicating mitochondrial iron deficiency. Interestingly, we also observed reduced expression of iron regulatory protein 2 along with impaired activity of mitochondrial aconitase and reduced mitochondrial superoxide formation in restless legs syndrome subjects. Along this line, patients had reduced mitochondrial respiratory capacity that improved in restless legs syndrome subjects under treatment with dopaminergic drugs compared with untreated patients.

Conclusions: Our data suggest that restless legs syndrome is linked to mitochondrial iron deficiency and associated impairment of mitochondrial function. This is partly corrected by treatment with dopaminergic drugs compared with untreated patients, which may be linked to an effect of dopamine on cellular iron homeostasis.

Huh! I found it interesting, also, that the doctors were from Austria and I wasn't familiar with most of them. Happy to see more people researching it as well as these very interesting findings!

I was able to take a look at the recent paper on RLS and suicide (link to abstract is near the top of this page). I wish I could post it here, but copyright prohibits it. The relationship isn't surprising to us, but there were a couple of things that stood out. Thoughts of suicide correlate with RLS having a 2.5 times higher correlation than controls. However, actual plans or attempts only correlate with severe to very severe RLS and not the milder forms (IRLSSG <20). Other statistics were not very surprising. The majority of RLS subjects had been through augmentation, most were female, the mean age was 50 and the mean IRLSSG score was 26. Also, the majority of the RLS subjects were Foundation members, which is an indication of the Foundation's recruiting efforts for Clinical Trials. There was a correlation between suicide plans and lifelong struggles with depression, but much less for those who only occasionally struggle with depression. Finally, there was no correlation between RLS suicide plans and sleep deprivation or un-refreshing sleep, which was rather surprising considering how much of a problem that sleep is and how it usually correlates with depression.

I'm surprised there was no correlation between sleep deprivation and and RLS suicide plans. The times that I have been at my worst and sleep deprived, I just did not want to live. I don't live alone, but I had been alone I'm not sure what would have happened. On the other side, I have never felt that I would follow through with anything.
I just felt so desperate.

Deb, I think that the authors were also surprised with that result, which is why they specifically pointed out the lack of correlation.
