There is no definitive answer on this, just a lot of research. What is clear is that it has a strong genetic link, and some 'candidate' genes have been identiifed that may imply a predisposition.
Having said that, what actually causes the illness to develop is unknown, although many believe that stress is strongly implicated. There is also evidence that it either causes, or is caused by, structural abnormalities in the brain, specifically enlarged ventricles. These are also found in schizophrenia, and are indistinguishable, implying some kind of link.

bipolar disorder has a strong genetic component. If you have immediate family that has it you are more likely to get it. there are also a lot of other factors ranging from environment to what season you are born in. A good resource for bipolar disorder is Dr. E. Fuller Torrey. He is an expert on schitzophrenia and bipolar disorder and has written several books for family, friends, and anyone else wanting to know about these disorders and they are very well researched and written for the everyday person

Everyone is bipolar, so are animals. Everything that can exsist in what we perceive as natural must also have an opposite. Hence 'disorder' Another medical label. Without it we would not know anything was wrong with us and be happy happy happy all the time. I think, anyway. I will only accept an argument from someone else who hasn't watched obligatory tv for 3 years also.

Check out this section of the Wikipedia entry for "Bipolar Disorder". It talks about research into the various causes of the disorder:

Wow, after seeing Uni's answer above, I had to re-read your question to make sure I understood what you were really asking!
Good luck with that Wikipedia article, anyway. I think you'll find what you want in section 6.

It does seem to have a genetic pre-disposition, but it can skip generations easily.
Not much is known - someone will probably tell you mercury in your cavity fillings, but that has never been proven.
I believe that it is being diagnosed more because more people are aware of it.
