Is Bipolar disorder hereditary?

I know that depression can be.

Yes, at least two thirds of those diagnosed with Bipolar disorder have at least one relative diagnosed with it. I am very familiar with this disorder as it runs in my family. My grandfather had it. Many(7 to be exact) of his descendants also have it. My grandfather lived before they knew anything about this disorder. However, doctors have concluded from my grandfather's pattern of behavior that he was a classic Bipolar. He could speak 7 languages fluently. The doctors have said this was possible because of manic depression. They call this disorder a "brilliant madness".

Yes most people that are Bipolar send it in there genes.

I don't think the actual disorder is hereditary but I think if it is in your family you are more prone (genetically) to have psychological problems like depression, anxiety, etc. I am fairly certain there is a connection from what I have seen.

pay no attention to the first person that responded, they have no idea, yes it is hereditary, my father has it,my son has it and my 4 year old daughter has it, and i doubt my daughter woke up one day and decided she wanted to be like her pa-pa and her brother, hey "blondech",can my daughter control her actions or her mental illness?

Yes, like schizophrenia. Ignore the idiot above me.

Bipolar disorder is genetic and biological. To address it as something you choose to have is ridiculous and ignorant. Someone like that should not post in this forum.

No,you control your actions
