Another frequently asked question is the following: If I have one child with ADHD, what are the chances that my other child is going to have ADHD as well?

Once again, this is a difficult question to answer without knowing whether or not there is a family history of ADHD. In families where one or both parents has ADHD, then the chances of having a second child with ADHD are somewhere between 25%-50%. However, if your ADHD child is the only one in the family with the disorder, then it is less likely that subsequent children will have ADHD.
