Unipolar and bipolar depression: different or the same?

  • Daniel J. Smith (a1) and Nick Craddock (a1)
Summary

The diagnostic boundary between recurrent unipolar depression and bipolar disorder may not be clear-cut and, further, the symptoms of unipolar depression compared with bipolar depression (although similar) are subtly different. Here we review the potential implications for clinical practice and research of new thinking about the relationship between recurrent unipolar depression and bipolar disorder.
