No single screening question settles a diagnosis, and bipolar screeners are especially poor: yeses often fall apart and noes often hide episodes once you get the narrative. Use well-written instruments before the visit and as prompts, but let the story decide.
Pitfalls and myths
There is no magic question that rules bipolar disorder in or out with confidence; there are no gold questions that tell you exactly what the problem is. Gather all the other data to adjust your assessment of probabilities, because you are making a treatment decision.
