"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 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.
The likely word is the slang term psycho, meaning insane, crazy (from psychopath).

Here's a guess. It could be related to the word "Batty" meaning crazed, insane or erratic. It comes from the term Bats in the Belfry because bats who lived in bell towers in Europe seem to fly erratically on occasions. "Old bat" is often used in the sentence "You crazy old bat." I suspect it was shortened to "Old Bat" because it is impolite to call someone crazy. It also seems to be reserved for women. I've heard people refer to an angry wife as the old bat as well as the old battle axe. In sum, I would suggest it is a less hurtful way of calling someone crazy either to their face or behind their back.
Bats fly in an erratic manner. A crazy person is similarly erratic.
A bat ghost can come from a bat that has been killed and want to stay.
