Does 3 months of iron supplementation treatment improve sleep as measured by actigraphy more than placebo? Does 3 months of iron supplementation treatment improve parent-reported and\u002For objectively measured attention more than placebo?\n\nResearchers will compare over-the-counter iron supplementation treatment to a placebo (a look-alike substance that contains no drug) to see if iron supplementation works to treat sleep difficulties in youth with ADHD.\n\nParticipants will:\n\n* Take iron supplements every day for 3 months\n* Visit the clinic once before treatment begins and once at the end of treatment to complete tests and rating scales related to sleep and attention\n* Wear motion-monitoring leg bands while sleeping for one 2-week period before treatment begins and one 2-week period at the end of treatment",[76,77],"ADHD","Sleep Problems",[76,79,80,81,82,83],"iron supplements","sleep","restlessness","attention","restless legs syndrome","NOT_YET_RECRUITING","2026-04-30",{"date":87,"type":88},"2026-05-04","ACTUAL",{"date":90,"type":69},"2027-03-01",{"date":92,"type":69},"2027-07-31",{"name":5,"class":6},1]
