Is There a Genetic Predisposition to Bipolar Disorder?

Vivian: I have bipolar in my family and would love to talk about it with you. Jeff: There are definitely genetic predispositions, but as we talked about earlier, it's not like there's one gene that's going to cause this. It's also the environment you grew up in. Vivian: You know how to contact me, you know what city I live? Jeff: Sure. So yeah, I've definitely left to get together.
