The other day I was reading a magazine about celebrities with bipolar disorder and could infer from that excerpt that the major percentages of people suffering from bipolar disorder are celebrities, or in fact more creative than the general people. However I could not find a justification to it, which these celebrities are actively social and they have to work extensively, as even a common person works a lot and has to spend time with family and friends as well. So can someone please elaborate on the major cause of such bipolar disorder?
