Mania or Hypomania? The Episode Classifier

Mania and hypomania use the same symptom list. What separates them is duration, impairment, psychosis and whether admission is needed — and that single distinction decides the diagnosis, the risk and whether an antidepressant is safe. Build an episode with the controls, then read the rule trace to see exactly which gate the episode passed or failed.

Criterion A — the mood and the engine

Quality of the mood
Abnormally increased activity or energy
How long has this been going, most of the day, nearly every day?
7 days 

Criterion B — DIGFAST

Three is the bar — unless the mood is only irritable, when it is four. Increased activity or energy appears twice on purpose: once in Criterion A as the engine that must be running, and once here as a countable symptom. If the person is elevated but the activity has not changed, the episode does not start.

Criterion C — severity, and the history

Effect on functioning
The three overrides
Lifetime history

Decreased need for sleep is not insomnia. A person in mania sleeps three hours and feels rested and energetic; a person with insomnia sleeps three hours and feels wrecked. Reduced sleep is the most sensitive early warning of an emerging episode and one of its most reliable accelerants — which is why sleep is a treatment target, not just an observation.

Ask before the antidepressant, every time

“Has there ever been a period of at least several days when you needed much less sleep than usual and still felt energetic?”
“A time when you talked much faster than usual, or people struggled to follow you?”
“A time when you spent money, made commitments or took risks that were out of character?”
“Has anyone in your family been diagnosed with bipolar disorder?”
And with permission, ask a family member — insight into past hypomania is often poor, because it felt like the best week of the year.
Why this matters. Most people with bipolar disorder first seek help when depressed, because hypomania is rarely reported as a problem — and the average delay to a correct diagnosis is measured in years. Antidepressant monotherapy in bipolar disorder can precipitate a switch into mania or hypomania, induce a mixed state, or accelerate cycling. A family history, an early age of onset, psychotic depression, and depression that has failed several antidepressants all raise suspicion. The Mood Disorder Questionnaire exists for exactly this screen.
