It is believed to be a genetic condition. If that is true, then identical twins will both have the same genes. However, it is also believed that environmental stressors trigger bipolar disorder, which means it is possible for one identical twin to develop the condition while the other does not.
hi, seems u both suffer from the same source, but since u r not identical and wouldn't matter if u were, u have two different outcomes because of many small factors but what u can do is help each other by keeping your OTHER on a path and not going too far to the side.
I wish u well; both
My identical twin is diagnosed bipolar. We have taken part in twin studies in to this illness. Regardless of whatever the studies eventually find, as an identical twin my feeling is that it is genetic and I am therefore at serious risk. I have even avoided contraceptions that have a higher 'depression' side effect because of it. However, one of the benefits of recognising mental illness is that you can take steps to protect yourself and, as yet, I've had no episodes, but I also exercise, get sleep, maintain a good diet etc. I firmly believe that people who acknowledge they are at risk of mental health problems (as we all are) are better able to take steps to protect themselves than those who think 'it'll never happen to me.'
