Yes, children can have early-onset bipolar disorder. It is much more common in those children who have a lot of "bipolar genes" in their family tree as your son does. It is quite rare for a child less then ten to be bipolar; if they become bipolar later on in life, they may show ADHD-like signs as a child that turn out to really be signs of early-onset bipolar disorder. Watch your son's behavior closely. This may be something else entirely, or it may be the beginning manifestation of bipolar disorder. Just remember that a lot of psychiatric disorders involve moodiness and strong-willedness in children. I once read a list of the symptoms of early-onset bipolar disorder, and I fit almost all of them, but I'm not bipolar. I have Asperger's. My psychiatrist and I both suspected cyclothymia for awhile because of my mood swings, which is why I was put on the mood stabilizer Lamictal. If your son gets any worse, or seems to be struggling with the moods he's already having, it would be advisable to take him to a doctor and maybe consider putting him on medication. Good luck, and God bless!
