First attested in 1908, from stir "prison" (1851), probably from Start Newgate (1757), prison in London, later any prison (1823), probably from Romany (Romic) stardo "imprisoned," related to staripen "a prison." Mid-19th century. Sturaban, sturbin "state prison" seem to be much later transitional forms.
The mentally ill are treated in hospitals and clinics that specialize in mental illness. The term 'crazy' and 'crazy people' is a generic term that can mean anything wild, violent, oddball, enthusiastic, or strange. A crazy person doesn't equal a mentally ill person. The word 'crazy' can be a positive or a negative description. Examples: She wears such crazy clothes. He's just girl crazy. When I said that, she went crazy. He ran like crazy. That was a crazy thing to do. I think the word you seek is an asylum.
"Bat Crazy" comes from "Bat S#&* Crazy." I haven't found a recorded instance of the word that includes its derivation. Anecdotally (unsupported claims of derivation), the term is said to come from an assumption that bats fly in apparently random patterns with sudden acute turns because they're crazy. Bats do not run into each other--which I find miraculous given how closely they fly together when exiting a space en masse. I suspect that the term "Bat S#&* Crazy" may have origins closer to "mad as a hatter," which comes from the fact that hatters suffered neurological damage from being exposed to mercury compounds used to make hats. Bat guano miners get histoplasmosis, but not neurological disorders. Even so, sometimes people make erroneous connections, so "bat s#&* crazy" may have come from some association between bat guano miners, chimney sweeps (exposed to bat poop) or some other population with a noticeable connection to bats and frequent neurological conditions.
The likely word is the slang term psycho, meaning insane, crazy (from psychopath).
A Bethlemite is another term for a Bethlehemite, an inhabitant of Bethlehem in Judaea, a slang term for a crazy person, or a member of an extinct English order of monks.
