The effect of iodine supplementation on cognition in school-aged children

This study is looking at whether giving iodine supplements to school-aged children who are mildly low in iodine can help improve their thinking and learning abilities. Researchers believe that children who are slightly short on iodine may think more clearly and perform better on mental tasks after taking a daily iodine pill for about seven months. You may be eligible if: - Your child is between 8 and 12 years old - Your child's iodine levels are mildly low (tested through a urine sample) - Your child does not have a history of thyroid disease - Your child is not currently taking any supplements that contain iodine You may NOT be eligible if: - Your child has a history of thyroid disease - Your child is already taking iodine-containing supplements Talk to your doctor about whether this trial might be right for you.
