Unipolar or Bipolar Depression? Heads or Tails? No Way!

In response to yesterday’s post, chipur reader, Wendy, threw bipolarity into the mix. And I’m glad she did. In response, I said I was going to post an article on the differences between unipolar and bipolar depression. And here goes.

Now, if one doesn’t have a lot of personal or clinical experience with the mood disorders, it may come as a newsflash that there are these two types of depression. Well, it’s fact; and making the distinction is absolutely crucial in terms of diagnosis, treatment; and, perhaps, the very survival of the one trying to endure it.

Let’s cut to the chase by first coming to understand this foundational differentiating characteristic…

If a depression is to be considered bipolar in nature a degree of mania is either a part of the equation or will be in fairly short order.

Now, disciples of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) will come up with all sorts of rigid criteria differentiating manic and hypomanic episodes. But for our purposes it’s best to consider mania within the context of a mood elevation spectrum. Actually, we could consider depression in the same light.

Okay, understanding there are per case differences, let’s take a look at the characteristics of unipolar and bipolar depression.


  • Impacts women more than men
  • Tends to present later in life
  • Difficulty initiating and sustaining sleep with early morning awakening
  • Loss of interest in eating, poor appetite, weight loss
  • Feelings of sadness, hopelessness, worthlessness
  • Restlessness, agitation, pacing
  • Episodes of longer duration
  • Possibly more responsive to treatment


  • Impacts women and men equally
  • Average age of onset around 18
  • Excessive sleep, difficulty awakening, daytime fatigue
  • Ramped-up appetite, occasional diminished appetite, binging, carb-cravings, weight gain
  • Feelings of sadness, hopelessness, worthlessness, guilt
  • Psychomotor retardation and inactivity
  • Severe anxiety; which may include panic, obsessions, compulsions, nervousness
  • Psychotic features – assorted sensual hallucinations, paranoia, delusions
  • Varying degrees of mania
  • Substance abuse
  • Much higher incidence of suicide

So there’s a quick reference guide. Again, presentations may, and very likely will, vary on a per case basis. And for gosh sakes, please don’t talk yourself into believing you’re presenting with any of these symptoms if it isn’t even a remote possibility.

That said, if you’re truly uncertain and concerned – or if any of the symptoms are in any manner interfering with your life – talk with your counselor, PCP, or psychiatrist. And if you don’t have one, get moving.
