What does dementating mean?
Dementating is a rare English adjective meaning maddening or causing extreme mental confusion. Unlike demented, which describes a person as insane, dementating characterizes an experience, image, sound, or influence as unsettling to the mind. The word is chiefly literary and now sounds deliberately old-fashioned or unusual, so it is more effective in stylized prose than in ordinary conversation. Its rare form can be distinguished from the more familiar adjective demented and the noun dementia, which refer respectively to mental illness or decline rather than a maddening effect. Dementating comes from the same Latin mental vocabulary as dementia: Latin dementare meant “to make insane,” and the English adjective was formed by adding -ing to the related verb dementate. The word is worth knowing because it preserves an unusually explicit link between language and ideas of mental disturbance, while offering a vivid literary alternative to maddening or bewildering.

Dementating is a linguistic time capsule: its Latin root means “out of one's mind,” while the word itself describes what it feels like to lose your reason.

Where does dementating come from?
Dementating was formed in English by adding the present-participle ending -ing to dementate, a verb meaning “to make insane.” That verb is based on Latin dementare, from demens, meaning “insane” or “out of one's mind,” which ultimately derives from mens, “mind.” The resulting adjective belongs to the same cognate family as dementia, dement, and mentality.
How dementating is actually used
Rare and chiefly literary. It sounds dated or deliberately archaic in modern prose and normally functions as an attributive adjective. It should not be used as a substitute for the more common demented when describing a person regarded as insane.
