monomaniac
One fixation only
A monomaniac is someone obsessed with a single idea, subject, or pursuit to an excessive degree.
The word suggests tunnel vision—an inability or unwillingness to think about anything else: He was a monomaniac about chess, barely eating or sleeping during tournaments.
The term can be clinical or colloquial, describing either a psychiatric condition or simply intense fixation.
