I ordered a DSM III online a month or so ago [I couldn’t locate an online version]. Since I got it, I’ve periodically looked through it and my reaction is always the same. I start moving back and forth through the pages, thumbing for an anchor to what I’m reading, confused [actually a bit anxious]. The part about depression is limited to one chapter, some 19 pages long – Affective Disorders*. I’m amazed that after thirty years, my reaction is the same as it was the first day I read through it – something like bewildered. I’m going back through the evolution of these criteria in depression to try to understand how we ended up with the category Major Depressive Disorder because it’s such a heterogeneous group – and the whole point of nosology is to refine diagnoses in the service of understanding disease and arriving at effective treatment strategies. I’ve been convinced that we’ll never do that with such an all-inclusive category. My recent reviews of the research and clinical trials of treatments has only strengthened that belief. But now that I’ve gotten to the DSM III, I find myself drawn back to that confusing time in my own life when it came out, and my reaction to it.
DIAGNOSTIC CRITERIA FOR MAJOR AFFECTIVE DISORDERS
|
||
BIPOLAR DISORDER | ||
296.6x Bipolar Disorder, Mixed | ||
A. Current or most recent] episode involves the full symptomatic picture of both manic and major depressive episodes intermixed or alternating every few days. | ||
B. Depressive symptoms are prominant and last at least a full day. | ||
296.4x Bipolar Disorder, Manic | ||
Current [or most recently] in a manic episode. [If there has been a previous manic episode, the current episode need not meet the full criteria for a manic episode | ||
296.5x Bipolar Disorder, Depressed | ||
A. Has had one or more manic episodes | ||
B. Currently [or most recently] in a major depressive episode. [If there has been a previous major depressive episode, the current episode of depression need not meet the full criteria for a major depressive episode.] | ||

- Which one do you have right now
- Do you have the full deal or a lite version
- What did you have before
Are we to think of this as one great big disease? a bunch of separate diseases? do we think they [it] are biologic? psychologic? Is the effort to separate them because they have different treatments? Why are they separated this way in the first place? why is a person who has had only manic episodes Bipolar? I didn’t get it in 1980 and I don’t get it now. And I don’t get how it’s either more medical or more scientific than what we had before. Other than removing any vestiges of the relationship of depression to mental life or life itself, it seems mighty arbitrary to me.
Trying to keep up here! very good points about differentiating the depression which is “endogenous” and “absent of any precipitating stress”. With this kind of depression, do you think currently available pyschotropics (i.e. SSRIs) are effective? Is your view based on your own observations and experience? It certainly appears we don’t have reliable clinical trial data (i.e. STAR*D)…wondering how you feel about Gary Greenburg’s assertion that “efficacy” is mostly placebo effect and enhanced placebo effect. Given the many people who have serious side effects with the meds and then difficulties withdrawing from them, would you be prescribing them if you were still practicing?
There are several remarkable features of the DSM-III criteria for Major Depressive Episode. First, they look like a description of melancholia lite. But then they contain a raft of additional symptoms that are not characteristic of melancholia. Depending on how one counts them, there are 19-20 possible symptoms in Criterion B, and only 4 are necessary. So, it is entirely possible for two patients to receive the diagnosis while having no symptoms in common (because Criterion A contains alternatives as well). This approach is called disjunctive, and it is a guarantee of heterogeneity in the diagnostic class.
Lacking, too, are any constructs linking the items in the menu of symptoms. The definition doesn’t help anyone to understand what sort of thing a Major Depressive Episode is. There is just the numbing empiricism of the menu.
Little wonder that clinical research in depression has been set back for the past 30 years. I recall that Robert Spitzer resisted including features like family history or response to treatment in the diagnostic criteria on the utterly specious ground that to do so would preclude investigation of, say, the genetics of depressive disorders.
Well, neurologists use family history all the time in the diagnostic process. Think Huntington disease. And neurologists use response to treatment in differential diagnosis. Think response to l-DOPA for distinguishing Parkinson disease from several look-alikes. The fact that such classic clinical ‘big facts’ were disallowed in psychiatric diagnosis underscores something Dr. Nardo has remarked upon already – the diagnostic criteria are stupefyingly unhelpful in clinical management.
Robert Spitzer and the American Psychiatric Association have a lot to answer for.
To make matters worse, compare the radical changes in the diagnostic algorithm for melancholic subtype in DSM-III, DSM-III-R, and DSM-IV; i.e., the major shift from III to III-R and back again in DSM-IV, all in just 14 years. Certainly these shifts were not informed by research data; rather, they were trial-and-error by committee. That’s not to say that best efforts weren’t made; rather, it underscores the difficulty of the task and our need to remain humble in future versions of DSM by not putting dogma before data.
