In a poster presentation at SLEEP 2015, researchers reported that children who have night terrors associated with restless leg syndrome appear amenable to treatment with ferritin supplements, reports MedPage Today.

“We started off by looking at children with restless legs syndrome and then we wanted to study a subgroup of those children — children who had parasomnias. Parasomnia is common in our cohort of children with restless legs syndrome and periodic limb movement disorder,” she said. Gurbani said that her finding of relief of parasomnias by treating restless legs syndrome could mean that, in some children, the restless legs syndrome/periodic limb movement disorder “may precipitate parasomnia.”
