I have also heard that adults with bipolar have had a higher incindence of “childhood adversity” which can include CEN. I think it may not necessarily cause bipolar but may “awaken” it or make it worse than it might have been. I am a survivor of CEN. I showed extreme anxiety as a child but did not show bp symptoms until I was well into my teens, although it MAY have been seventh grade. Hard to say. But the CEN has definitely caused a whole host of other issues that are not necessarily related to my bp.
