What does apoplexy mean?
Apoplexy is a noun with two main senses: a historical medical one and a living figurative one. Medically, it once described a sudden collapse into unconsciousness or paralysis brought on by bleeding or a blockage in the brain — what modern medicine calls a stroke. Because early doctors could not distinguish between different causes, 'apoplexy' became a broad label for such sudden neurological events, and it appears constantly in older records, literature, and death certificates. Today the literal sense survives mainly in historical contexts, while the figurative sense thrives: to send someone into apoplexy is to provoke overwhelming rage or indignation, a usage especially common in political commentary and everyday speech. The adjective 'apoplectic' carries this figurative force and remains far more current than the noun. The word lends writing a slightly old-fashioned, dramatic flavor, making it useful both when discussing medical history and when describing theatrical outbursts of anger.
Sudden impairment of consciousness or paralysis resulting from rupture or obstruction of blood vessels in the brain; formerly the standard medical term for a stroke.
"Coroner's reports from the period list apoplexy among the most common causes of sudden death."
Now largely obsolete in clinical practice, having been superseded by 'stroke'; retained chiefly in historical or literary contexts.
A state of extreme rage, indignation, or agitation.
"News of the merger sent shareholders into apoplexy."
Figurative and somewhat informal; often used hyperbolically in journalism and political commentary.
Rarely pluralized; the singular is standard even when referring to multiple events, which are usually described individually as attacks or strokes.
"The patient's history recorded several apoplexies over the preceding decade."
For centuries doctors diagnosed people as dying of 'apoplexy' — a catch-all that turned out to be what we now simply call a stroke.

Etymology of apoplexy
Apoplexy comes from the Greek 'apoplēxia', derived from 'apoplēssō', meaning 'to strike down' or 'to cripple by a blow' — from 'apo-' ('away from') plus 'plēssō' ('to strike'). The idea was that the sufferer had been struck down as if by a blow, reflecting ancient beliefs about sudden paralysis. The word entered Latin as 'apoplexia' and passed into English via medieval medical learning, becoming established in English medical texts by the early modern period. It shares its Greek root with related terms such as epilepsy and catalepsy, which likewise describe conditions of being seized or struck down.

How apoplexy is actually used
In contemporary medical writing 'apoplexy' has been almost entirely replaced by 'stroke', so its literal sense now sounds archaic or historical. The figurative sense — extreme fury or indignation — is common in journalism and informal speech, often in phrases like 'went into apoplexy'. The related adjective 'apoplectic' is more widely used than the noun itself for describing intense rage.
