What does dementated mean?
Dementated means mentally deranged, irrational, or wildly confused. It belongs to the same Latin-derived vocabulary as dementia and dementate, although the modern adjective does not necessarily indicate a specific medical diagnosis. The word can describe a person whose thoughts or behavior have become disordered, as in a reference to a "demented witness," and it may also qualify an idea, plan, or account presented as absurd or irrational. In contemporary English, dementated is relatively uncommon and has a chiefly literary, archaic, or historical tone; demented is much more familiar. Its appearance may therefore suggest elevated prose, an old-fashioned setting, or a deliberately heightened description of confusion. Even when the expression refers to an individual, it is normally figurative or literary rather than a responsible clinical description.

Where does dementated come from?
Dementated comes through the Latinate English formation dementate from Latin dementare, meaning "to make insane." That verb is connected with Latin demens, meaning "out of one's mind," and ultimately with mens, mentis, meaning "mind." Its best-known English relatives include dementia, formed from Latin dementia, and the archaic noun dement, meaning mental derangement.
