Ludwig's WRAP-UP

The phrase "become insane" is a well-established English expression used to describe a shift into a state of madness or irrationality. According to Ludwig AI, the phrase is most frequently found in News & Media and Encyclopedias, where it often documents historical figures or extreme social phenomena. While it is grammatically correct and effective for dramatic or descriptive writing, modern writers should be mindful of its sensitivity and clinical imprecision. In professional health or scientific contexts, it is often replaced by more specific medical terminology. However, in general writing, it remains a powerful tool for conveying a total loss of order or reason.
