If I have ADHD, will my child also have it?

No, not necessarily, but the chance is definitely greater than if you did not have ADHD. For example, onethird of fathers with a history of ADHD in childhood have a child with ADHD. For mothers, the percentage is somewhat lower. Sometimes, it is a male relative in the mother’s family who has ADHD. Mothers presumably have the ADHD gene, but they may exhibit few or no symptoms. Nonetheless, these mothers can pass the ADHD gene on to their children.We are still not sure why females are less likely to have ADHD symptoms, even when it is almost certain they have one of the ADHD genes. In one study of ADHD adults and controls, 43% of children with ADHD parents met criteria for a diagnosis of ADHD, compared to 2% of children in the control group of children who had parents without ADHD. If your first child has ADHD, the risk of your second child having ADHD is probably higher than in the general population. However, predicting the severity of ADHD or the type of ADHD that might run in a family is not possible.
