It depends on the type of games. Several studies were done and the results were that computer games help a lot with children with ADHD, they discovered that after a period of time, these kids were able to spell and read better than if they sit down and do "normal" work. Let's not forget that kids with ADHD are not your typical kid sitting down and doing work, you need to find innovative ways to help develop his brain and capacities. Children with ADHD are very good with computers and anything related to art so I think the key is explore these areas so the child not only learn but also feel good about himself and his little achievements.
