This person needs to be in a mental institution, not their house. This is also closely related to the crime problems people have with high-density living. The complete and utter failure of our society to correctly put people away is not a knock on "high density living", it's a symptom of the US shutting down asylums and preventing people who are dangerous to society from being locked away.

I'm with you in theory, but given it was the medical industry that damaged her in the first place, her mother is understandably very apprehensive about them having further access to her.
You neglect the dark side of this "lock the crazies away" solution: the so-called "doctors" are given full access to the person to arrange for whatever medical procedures they deem fit, with zero checks and balances, at the taxpayers dollar. In her case the "doctors" convinced her non-english-speaking parents to put their healthy daughter through a surgery generally considered elective/postponable at a very young age and (accidentally?) suffocated her while she was under, thereby permanently destroying her brain for life. The total amount taxpayers will pay the medical-pharmaceutical complex to keep her vegetive for her entire life is difficult to fathom.
When those decisions were made (to shut down asylums, etc.) what techniques were intended to backfill the same need? Did evidence suggest that something else (drugs at home?) would be at least similarly effective and more humane?

Generally, the umbrella term for the intended replacement is "community-based mental health services," and that embraces a fairly broad continuum of care, in principal.
Among the things that did not happen was sufficient funding for these to be adequately provided publicly, or assurance that non-institutionalized, privately-insured people would be likely to have these covered by private insurance. While some progress on each has been made since, access remains an issue, as does service delivery, especially with the unhoused. (One thing that was not provided for with the withdrawal of institutionalization was a replacement for the room and board inherent in institutionalization.)
