I agree, “psychosis” is a meaningless “symptom.” According to my psychologist’s medical records, she thought thoughts, guts instincts, and dreams were all “psychosis.” Using her definition of the word “psychosis,” this would mean the entire world is “psychotic.” Which may be true, but that’s a whole different topic. “The report begins by reviewing what has been commonly understood as psychosis (hearing voices, believing in things that others find strange, speaking in ways others find difficult to understand, and experiencing confusion that might be perceived as a loss of touch with reality).” You forgot the number one reason psychologists and psychiatrists claim someone is “psychotic,” believing one was abused, sexually assaulted, or having concerns of child abuse of any sort. We know this is the number one reason for being diagnosed as “psychotic” because today, “the prevalence of childhood trauma exposure within … individuals diagnosed with psychotic or affective disorders, [childhood trauma exposure] reaches 82% (Larsson et al., 2012).” I agree “schizophrenia,” and all the DSM disorders, are stigmatizations that do more harm than good to the “service users.” But I’d like to point out that the primary etiology of “schizophrenia” is likely the treatment, thus iatrogenic, as opposed to “genetic,” in nature. Today’s “gold standard schizophrenia treatments,” the neuroleptics/antipsychotics, can create the negative symptoms of “schizophrenia” via neuroleptic induced deficit syndrome. https://en.wikipedia.org/wiki/Neuroleptic-Induced_Deficit_Syndrome And the neuroleptics/antipsychotics, and antidepressants, can create “psychosis,” one of the positive symptoms of “schizophrenia,” via antidepressant or antipsychotic induced anticholinergic toxidrome. https://en.wikipedia.org/wiki/Toxidrome But since neither of these known neuroleptic induced illnesses/poisonings are listed in the scientifically invalid DSM, they are always misdiagnosed as one of the billable DSM disorders. But the bottom line is the “schizophrenia treatments” do create both the negative and positive symptoms of “schizophrenia,” and the “professionals” claim to be ignorant of this reality.
