Key moments, in order
Its value is a shared language. Before it there were a billion different theories and nosologies, everyone called everything differently, and there was no way to communicate.
Literature before and after 1980 may not be describing the same patients under the word schizophrenia.
Never trust a pre-1980 schizophrenia diagnosis, and do not trust any diagnosis until you verify it yourself. Older definitions were too loose, sweeping in anyone with disturbances of thinking, mood and behavior, so schizophrenia in older texts is not the same group of patients we mean today.
The proper psychotic disorders are not psychological in origin. They are brain disorders, a disruption in the reasoning and perceptive networks, even though the way symptoms manifest is still psychologically rooted.
Kraepelin was one of the first not to take symptoms at face value: he tracked symptoms, how the diagnosis changed after treatment and how patients did after discharge. Follow the course the same way.
Kraepelin defined manic-depressive illness by recurrent mood episodes, not by polarity, so today both recurrent major depression and the bipolar disorders would fall under it. What resembles a bipolar disorder genetically and biologically is less the strict DSM definition than a recurrent, episodic, primary mood disorder.
Freud did not work with primary psychotic illness; his ideas came mostly from patients with hysteria. Writers on schizophrenogenic mothers and developmental causes never demonstrated that those were causal.
In the proper psychotic disorders and in bipolar disorder, every episode that goes untreated is burning brain.
Duration of untreated psychosis rests on the idea that psychosis is almost toxic to the brain: the longer someone is psychotic, the more damage, potentially irreversible, it can do.
Aberrant salience: the brain attributes importance and surprise to mundane things at random. Delusional perception, or ideas of reference, is attributing importance to a stimulus others would not find important, and how that happens varies a lot from person to person.
The longer the processing of the world is off, the more beliefs get chipped away. An hour of psychosis may knock off some unimportant beliefs; longer reaches deeper.
Heavy methamphetamine use can cause so much disorganization and delusion that, even after stopping, the person looks exactly like someone with schizophrenia. A paranoid delusional belief system that began on methamphetamine can persist after the perceptions that fed it stop.
Do not take what patients say as an accurate picture of their inner state. Someone with schizophrenia may start denying the delusion mid-interview because they can still read your social judgment, and people with chronic psychosis learn not to talk about certain things. That is social learning, not remission.
Two-factor theory: you need a strange experience, and a second problem that prevents the idea from going away.
Responses to treatment differ. Some patients, once antipsychotics stop the delusional perception, say they remember feeling that way but it seems strange now.
Autism and general personality oddness mimic psychosis, but they are also risk factors for true psychosis. Cluster A traits can bring quasi-psychotic experiences without a psychotic disorder.
Biases that build into delusions include a bias against disconfirmatory evidence (less inclined to give an idea up) and a jumping-to-conclusions bias (accepting a hypothesis on minimal evidence, seeing something once and generalizing it).
You cannot define a delusion by its truth value: you can be delusional about something and be right. If a man's jealous delusion is built on nothing, it does not matter whether his wife happens to be cheating.
A delusion is a pathological belief that comes from a psychotic disorder. So identify the psychotic style of thinking first, and test it.
Build your calibration by also probing, not meanly, the deeply held beliefs of people without psychotic disorders, not just testing delusions.
Do not take statements at face value. Ask how they came to understand this to be true, what experiences led to it and when they started to believe or suspect it, and how they respond to alternatives. How did you come to understand that you are Jesus Christ?
Loose rules for calling something a delusion, applied by clinicians with less experience of severe psychotic disorders, lead to a lot of unnecessary antipsychotics.
In the emergency room, the standard for involuntary hospitalization is acute danger to self or others.
A large share of people from the old asylums and state hospitals moved to jail and prison, which has hurt most psychiatrists' ability to detect and understand psychotic disorders.
Moderate-grade psychosis often goes unnoticed, but it can affect people's decisions, thinking and beliefs about the world.
They block dopamine, which makes them literally anti-addictive and incredibly unrewarding to take.
Newer, mood-helping, weight-light antipsychotics still need watching for akathisia. It is very uncomfortable and a big reason people cannot take the medication.
The meds work really well; the problem is that they are not fun and have bad side effects. The challenge is building a relationship in which the patient trusts you and your recommendations.
Lack of insight is the most common symptom of schizophrenia in some frameworks, so explaining the diagnosis and the antipsychotic will not make anyone say they should take Haldol. Ask instead what is a problem for them.
Your job is not to get the patient to say they have schizophrenia. The patient who says "I don't have schizophrenia, but I take my clozapine every day" does better than the one who accepts the diagnosis and refuses the medication.
Find common ground in concentration, sleep, fear or stress. You are not lying when you say the medication helps those, and there is no point talking about a pathology someone does not think exists.
Find common ground in what the patient sees as the problem, and pick the medication with the fewest side effects you have access to.
Tell them it is an antipsychotic, and also the truth: first- and second-generation antipsychotics are used across many conditions.
The newer medications are not more effective, but they are certainly better tolerated.
