Yes, many people who have bipolar disorder will become manic when given antidepressants. But an antidepressant making someone manic who has no prior history of any degree of mania cannot, technically, be the criteria for a diagnosis of bipolar disorder.

What often happens is that someone who is being treated for unipolar depression is given an antidepressant without any sort of counteracting mood stabilizing agent and they soar off into a manic episode. Well, upon closer examination, once the patient is asked the right questions, it is discovered that they have, in fact, had some history of mania but it was not diagnosed as such. It may have been a very angry, dysphoric mania or perhaps the person had just come out of a depression and was finally feeling really (really, really!) good and the last thing they thought about doing was going to a doctor because, hell, they're feeling GREAT now! Those are the people who can, technically, be diagnosed with bipolar after becoming manic on antidepressants. The antidepressants bring attention to the history that was already there. They do not create the history by themselves.
