It may be natural, but so is down syndrome. You can be born with a disease. Though some more serious than others.

It's a psychiatric disorder caused by abnormalities in the brain.

It's not a disease in the sense that it's caused by a virus or bacterial infection, but it's an infliction that can not be controlled by the person.

Similar to schizophrenia.

Smallpox is natural. Chlamydia is natural. They're also diseases. Same applies to Bipolar.

I guess what you are asking is can a genetic imprefection be classified as a disease. The answer is yes, a genetic imperfection can be classified as a disease (yes, some are labeled syndrome or other names). I have a genetic form of arthritis...got it from my dad...it is a disease and it is genetic.

So, yes Bipolar should be considered a disease.

Yes, it's not natural, you can't just be born with it, it adds up over time... the bi polar ness... :D

amanda bipolar disorder is a really serious thing and you DONT have it. if you really think you do you should go to like a doctor or something.

Are you kidding me? My sister suffers this DISEASE and it is not natural. People who act 'sort of' bipolar Are doing so because family or social related PTSD . Without treatment with medication bipolar will NOT get better.
