A new study suggests that sleep problems in children with autism spectrum disorders (ASD) may frequently stem from a condition known as restless leg syndrome (RLS).
Restless leg syndrome causes unpleasant sensations in the legs that lead to an overwhelming urge to move them. The symptoms are strongest in late afternoon and at night, and are most severe when people are resting.
A new study suggests that sleep problems in children with autism spectrum disorders (ASD) may frequently stem from a condition known as restless leg syndrome (RLS). Restless leg syndrome causes unpleasant sensations in the legs that lead to an overwhelming urge to move them. The symptoms are strongest in late afternoon and at night, and are most severe when people are resting. any symptoms involving the legs highly correlated with the diagnosis of RLS.” The researchers add that nearly all of the children responded positively to treatment. Interventions included iron supplementation (given to 25 children, with 23 improving), the anticonvulsant gabapentin (given to 12 children, all of whom improved), or combination therapy (given to 3 children, all of whom improved). They conclude, “Initial assessment [of sleep problems in individuals with ASD] should include a thorough query of behaviors related to nocturnal motor complaints, because RLS may be a treatable cause of sleep disruption.”
