Has anyone heard about this research? It looks quite significant?
. “Adenosine by the way, regulates the sleepiness associated with prolonged wakefulness,” explains Dr. Ferré. In the cortex, thalamus and other areas of the brain, adenosine modulates homeostatic sleep. Low levels of adenosine receptors could explain the hyperarousal of RLS. “The beauty of the adenosine story is that it connects the hyperarousal symptoms with movement [PLMS],” he says.
“What is really important about our story is that maybe we have found a mechanism – the adenosine system – that links brain iron deficiency to hyperglutamatergic and hyperdopaminergic states.”
This insight can be used to potentially develop RLS treatments that increase the concentration of adenosine to prevent both PLMS and hyperarousal. One such drug is already available clinically: dipyridamole, an antiplatelet drug that protects against stroke and heart attack.
