CrowdStudying Ourselves: Approaches to Bipolar Disorders, Part 2
A window into what your colleagues actually think and do.
In Part 2 of this series, I again ask for your feedback to help provide a window into what practicing psychiatrists actually think and do. When we have a large N, I’ll add a synthesis of the series.
The questions in
When you assess a patient with depression, which most closely describes your approach? Please answer in the comments box. Please indicate if you are a non-clinician.
Answer: Option A is justifiable per the structure of the DSM: if criterion A (elated, expansive, or irritable mood, with increased energy) is not met, the diagnosis cannot be supported. Given the DSM’s widespread use and acceptance, and the fact that it remains the official diagnostic system of the American Psychiatric Association, one could argue that A is the “correct” answer.
You might have picked option B because you assess the B criteria even when A criteria are weak (eg, of less than 4 days’ duration). Many practitioners use the DIGFAST mnemonic to remember the B criteria (
Option C: the spectrum view
Controversy continues regarding the validity of the DSM cutoffs. Whereas the new “increased energy” criterion in the DSM-5 was supported in a
Likewise, if you’ve been in practice for long, you’ve seen all sorts of variations of the B criteria, from obvious to subtle to uncertain to dubious-but-not-clearly-absent. Such observations make sense with the finding of
Thus, prominent mood specialists-including the
Option D
You always take a family history in a new patient, right? Why? Because you know that depression in a patient whose first-degree relative has a reliable diagnosis of bipolar disorder (eg, “Oh Dad, when he didn’t take his lithium, he’d end up in the hospital, but on it, he did well for years”) is more likely to be bipolar depression than if the family history were negative. A positive family history does not make the diagnosis of bipolar disorder, but it strongly influences the probability thereof.
If it makes sense to take a family history, then it makes sense to check all the other variables that have also been statistically associated with bipolar outcomes.
The Bipolarity Index
The Index includes the DSM criteria but adds 4 other components (a quick way to assess all this is presented in
Notice: the
Questionnaire approach
Between the A and B criteria of the DSM, there are 11 variables. In the Bipolarity Index, there are an additional 10 to 11 variables, depending on how you count. That’s over 20 individual questions-too many for an initial interview in which you are not just gathering data but laying the groundwork for shared decision-making and treatment, already an overloaded agenda.

The next essay in this series will focus on that questionnaire, called
