Mania (psychology)
Etymology
From Greek “mania” (madness or frenzy), related to “mainesthai” (to rage) and “menos” (spirit, force, passion). In casual English the “-mania” suffix drained into mere enthusiasm — “Beatlemania” — but the clinical term keeps the older, weightier sense of a mind driven beyond its own control. The word has named excess of spirit since antiquity.
noun · /MAY-nee-uh/
A state of abnormally elevated mood, energy, and activity, often with racing thoughts, little need for sleep, and impaired judgment.
What it names
The “up” pole of mood disorders — a state that can feel euphoric and unstoppable from the inside while leading to reckless, damaging decisions.
Example
During the manic episode he maxed out three credit cards and slept two hours a night, convinced every plan would work.
Related idea
Mania is the intense high; hypomania is a milder, less disruptive version of the same state. Both sit opposite the lows of depression in bipolar disorder — and the everyday sense of “mania” as mere passionate enthusiasm loses the clinical meaning entirely.
noun · /MAY-nee-uh/
An intense, widespread, and often irrational enthusiasm or craze for something.
What it names
a collective obsession or fad
Example
Tulip mania gripped the Dutch in the 1630s.
Related idea
Distinct from the clinical mood state — here it is a fever of desire that can seize a whole market, often ending in a burst of exponential-growth.
