MDD versus bipolar II comprehensive assessment guide

The comparison is the vehicle and the assessment is the destination. Every version of this question ends with the same clause — particular emphasis on how comprehensive assessment could help us arrive at the correct diagnosis — and a post that lists diagnostic criteria in two columns has stopped one step before the question. Criteria tell you what distinguishes the disorders; assessment tells you how you would find out which one is in front of you, given a patient who arrives depressed and does not volunteer anything else. That is the clinically interesting problem and the reason these particular pairings were chosen. Structure the post so the comparison occupies the first half and the assessment argument the second, and make sure the second half names methods rather than restating the differences you have already listed. If a sentence in the back half could have appeared in the front half, it is in the wrong place.

The pairing you are assigned determines what the assessment has to detect, and each of the three has a different hard part. Major depressive disorder against bipolar II turns on hypomania, which patients rarely report as a problem because it does not feel like one — it feels like being well, or productive, and it is often recalled only when someone else describes it. Bipolar I against bipolar II turns on whether an episode ever met the threshold for mania rather than hypomania, which is a question about severity, duration, psychosis and hospitalisation. Bipolar II against cyclothymia turns on whether any episode ever met full criteria at all, and on the two-year chronicity requirement. Say which distinction yours depends on in your opening lines, because the entire assessment argument follows from it and a reader who has to infer it will read the rest as generic.

That leads to what comprehensive means here, and it is concrete rather than rhetorical. Collateral history from family or partner, because the person who noticed the hypomania is usually not the patient. Longitudinal history rather than a cross-sectional snapshot, often built with a life chart or mood timeline. A screening instrument used properly and with its limitations stated. Medication and substance history, since antidepressant-associated switching and stimulant use both complicate the picture. Family psychiatric history, which shifts the prior probability before you have asked the patient anything. Naming three or four of these, and saying in a clause what each one would settle, is a stronger answer than a general endorsement of thorough assessment — and the peer-reviewed evidence the rubric requires is far easier to attach to a named instrument or method than to a general claim about thoroughness. Search for the instrument, not for the disorder.
