childhood bipolar disorder

It can cause early sexual abuse in bipolar disorder?
My friend is bipolar and recently said she was sexually abused as a child. She said she always had bipolar since I can remember. Could your bipolar be the result of the horrible things that happened to her? Or is it strictly hereditary? She says it is hereditary, not for what happened, but I disagree. I know that multiple personality disorder is usually caused by the trauma of the first childhood bipolar but can also be caused by this? Are your connections between the two? Does anyone here have bipolar, and what is your opinion? I'm curious about this disorder and what causes it.
It's a possibility .. But he says he has to do with genes, as well .. because in many cases people who have been diagnosed with Bi-polar also have to run in another part of the family. The disorder can appear when you're a child, but usually when you're a teenager +. I do not say psychologically traumatic event that something could not trigger bi-polar and Parani, because it is very likely to be able .. Living in unstable ENVIRONMENT. The disease is still investigating, but you can always read more about it and see if you find useful information in it .. So sorry about your friend, nobody should have to deal with that .. But what does not kill because it is more than just strong! All my luck to her and shes lucky to have a friend like you.
