Bipolar Disorder (Children and Adolescents)
Bipolar Disorder and Genetics
I have heard that bipolar disorder will skip generations, which I don`t believe. What are the chances that if a mother is diagnosed with the disorder, the daughter could have the syptoms also.
Hello and thank you for your excellent question.
Regarding skipping generations, although I do not know of any published studies, clinically I have heard of grandparents having the disorder, their children not having it, and their grandchildren developing it. It probably occurs less than 10%.
Quoting from Dr. Mary Fristad`s excellent book about childhood bipolar disorder, "Raising a Moody Child":
"If one parent has a mood disorder (bipolar or depression), the couples` children have a 27% chance of developing a mood disorder. That risk increases to 74% if both parents have a mood disorder."
I hope that answers your question.
