Summary

This study looks at whether a set of thinking and memory tests can detect changes caused by a stimulant medication in children aged 6 to 17 who have both intellectual disability and ADHD. About 68 participants will receive either the medication or a placebo, then switch after a break. The goal is to see if the tests are sensitive enough to measure the medication's effects on attention and behavior.
