The most important difference

• Both mania and hypomania involve a distinct change in mood and energy, but mania is the more severe syndrome.
• Once the episode causes marked impairment, requires hospitalization, or includes psychotic features, the picture moves out of hypomania and into mania.
• That distinction matters diagnostically because a single manic episode is enough for bipolar I disorder.

What to ask clinically

• Ask what the elevated state did to the person's functioning, not just which symptoms were present.
• Look for downstream consequences such as extreme spending, sexual risk, aggression, legal problems, psychosis, or collapse in work and relationships.
• Collateral history is often what separates a brief energized stretch from a true mood episode with diagnostic weight.
