Imagine a murderer who has been arrested and imprisoned recenly and he has been tried in the court several times! The judging team members, have reached to an agreement on his case and unanimously believe that it has been an instantaneous insanity and "at least" they cannot sentence the murderer to death. Irrspective of the law regulations which can differ from country to country, in the following example, I need to know whether there is a normal (not too legal) verb to be used along with the term "instantaneius insanity" in English in the manner that the combination could be understood to ordinary people who have experienced academic environment (not only legal people)?
- It was diagnosed to be an instantaneous insanity. Consequently, it is clear that he has come upon / faced / experienced an instantaneous insanity.
Do the above-mentioned bold verbs work here naturally and idiomatically or there is a/some fixed verbs to be used beside this psychological term?
Ps. It is a self-made story and I do apologize in advance because of some possible syntactic errors or mistakes in sentences' construction which can make my meaning a little unclear.
