The only differences between Unipolar and Bipolar depression are that bipolar is characterized by cycling moods and depression is generally more stable. Also the psychotropic drug treatments are different for unipolar and bipolar disorders. Depressed people need pick-me-ups called SSRI's, or MAOI's such as zoloft, while bipolar people need mood stabilizers (e.g. Lithium) and anticonvulsants (often the exact sa
