Treating any single manic episode as automatically bipolar
-
1. The tempting shortcut
"He's manic, so it's bipolar."

2. Stop and think
Before you read on: what is wrong with this reasoning? Try to answer in your own words, then reveal the explanation below.
-
3. Reveal — why it fails
Bipolar affective disorder (F31) requires a documented course of at least two episodes, with at least one being manic, hypomanic, or mixed. A single, first-ever manic episode with no other episode of any kind on record is classified as F30, a distinct category that exists specifically for this situation. Severity, and even psychotic features, do not change this — only episode count does.

4. Reveal — the better reasoning rule
- Has any manic, hypomanic, or depressive episode ever occurred before this one, at any point in the person's history?
- If this is genuinely the first episode of any kind, F30 applies, however classic or severe the current presentation.
- If a second episode of either pole is later documented, the classification should be reconsidered at that point.
Corrective example: In the F31 anchor category, a first-ever manic episode with no prior episode of any kind is classified as F30 (single manic episode), not F31 — the course requirement is checked before, not instead of, grading the current episode's severity.
5. Try the transfer case
Apply the better rule above to a fresh case.
