What is "autisms"

Usage examples of "autisms".

The small handful of Wamphyri diseases were mainly hereditary: various animalisms, several forms of insanity, aggressive autisms, acromegaly and other bone disorders.

As for grotesque autisms - bone and brain disorders - tendencies to extreme violence and madness - 'unnatural' lusts: what else would one expect?

I exclude, of course, the various mutations, autisms, metamorphisms and madnesses with which the Great Vampires were ever afflicted, if afflicted is the right word.
