Had (knew) a female that lived next door when I was growing up that was diagnosed with it, havent seen her in almost 10 years ago but the family moved away from the old neighborhood about a year ago.
Dont think she was diagnosed until she was about 30 or so dont know how someone like that is delt with without family as her mom is about 90 so wont be around much longer.
Group homes and the like. Contrary to popular belief, Reagan didn't kick everyone out of Institutions and loose them on the streets. Psych care changed at the same time and didn't want mentally ill people condemned to essentially prison. Most schizophrenics are harmless with a minimal of supervision and medication. They can hurt themselves and others when untreated.
Medications changed about that time as well, newer Anti-psychotics came on the scene, so not all Schizos were zombied out on Thorazine. The age of atypical antipsychotics, you see them on TV like Abilify. That type of drug started in the late 1970s around the time Reagan came to office. The first wave was in the early 1960s when they moved away from Lobotomies.
So what happens is people, usually in their 20s, will have an incident with their family and aging parents, then go to an institution where they straighten out their meds. Then they are released and go to a group home or back home. Usually in an out until they end up permanently in group homes. Of course they are people and as they age, their hormones go down and their incidents go down in frequency as well.
Saw much of this while homeless. Many schizophrenics know they are, and struggle, mostly successfully, with paying attention to what is real and what is in their mind. And many of them do not belong in group homes or institutions, the street is literally the best place for them, and the social workers take care of them first.
So many misconceptions about homelessness in this country. You get an upper-class Karen involved and they want to cure everything with their abundance of love and altruism. Sometimes, many times, the bag lady is best off as a bag lady, known by the local shelters and workers, taken care of by the other homeless. Most homeless now are wasted drug addicts, but the core of homeless take care of each other until they don't and then you see it on the news.
