Usage notes
While within the United States and Canada, the word mad'' ''does'' generally imply ''anger'' rather than insanity, such usage is still considered informal. Furthermore, if one is described as having "gone mad" or "went mad", this will unquestionably be taken as denoting ''insanity''''', and not anger. Meanwhile, if one "is mad at" something or has "been mad about" something, it will be assumed that they are '''''angered'' rather than insane. In addition, if the word is understood as being used literally, it will most likely be taken as meaning "insane". Also, in addition to the former, such derivatives as "madness", "madman", "madhouse" and "madly" ''purely denote insanity, irrespective of whether one is in the Commonwealth or in the United States. Lastly, within Commonwealth countries other than Canada, mad'' typically implies the ''insane'' or ''crazy'' sense more so than the ''angry sense.Synonyms

Adjective
(en adjective)- What is the cause of insanity?
Nobody can answer such a sweeping question as that,
but we know that certain diseases, such as syphilis, break
down and destroy the brain cells and result in insanity. In
fact, about one-half of all mental diseases can be attributed
to such physical causes as brain lesions, alcohol, toxins,
and injuries. But the other half—and this is the appalling
part of the story—the other half of the people who go in-
sane' apparently have nothing organically wrong with
their brain cells. In post-mortem examinations, when their
brain tissues are studied under the highest-powered micro-
scopes, they are found to be apparently just as healthy as
yours and mine.
