Who is the first real schizophrenic ever? The answer is at the end.
Firstly, "schizophrenia" as defined & diagnosed by pseudoscientists - psychiatrists & psychologists - doesn't exist. These cases are either deliberately misdiagnosed or done so out of ignorance. People can & do suffer symptoms of "schizophrenia" for various reasons, including neurological disorders, but it's not schizophrenia in the sense that there is a permanent affliction of a mental disease. Do not confuse "neurological" with "mental". It's not the same.
"Schizophrenia", and many other mental disorders such as "bipolar", are inventions of lies used to push an agenda, including belittling the spiritual state of faithful people, bonding them to a pill for the rest of their lives, and putting them on a state or national registry that bars them from exercising their inalienable right to possess a firearm. It's a political tool to control the population - person by person.
Light to moderate "schizo" symptoms in most people (erroneously) diagnosed with "schizo" can be alleviated by at least one of these two effective stimuli - 1) getting physically beat down (ass kicked) and 2) consummation within marriage.
Most severe symptoms, which are not neurological in origin, are prevented & alleviated by the Holy Ghost and having a true spiritual relation with Jesus Christ, and receiving the Sacraments.
Most "schizo" symptoms can, ultimately, be traced back to the hurt pride of a person. An ass-kicking might sound counter-intuitive to alleviating "schizo" symptoms because a person's pride will, momentarily, be affected, but an ass-kicking clears away all delusions, and it allows the natural order of things to be seen and honestly accepted. The honest & brave person will then rebuild what is proper and avoid harboring any misguided emotions & thoughts that led to the symptoms. The dishonest & cowardly person will likely continue to have symptoms, which might even intensify because their pride won't let them move on from whatever failure or trauma they experienced. Their false ego is anchored into their pride, which only generates hostile symptoms to a person's mind, emotion, spirit & body.
Only a small minority of cases are truly neurological that result from head trauma or things like auto-immune encephalitis, but it's still not "schizo". It can, however, give off strong symptoms that are exactly attributed to "schizophrenia". Most "schizo" cases are of a mental and / or spiritual origin. They are certainly not "schizophrenia".
Basically, most people with "schizo" are butt-hurt over something they can't control and / or can't have... hence, their variable symptoms.
Guess who was the first real schizophrenic ever?
The answer is Lucifer.
He thought he was, or wanted to be, equal to God, hence the host of problems within him that followed - his rebellion and everything. Now he roams the world seeking to devour as many souls as possible, and in the process these people experience variable symptoms of "schizo".
Pride.. it all stems from pride... people are butt-hurt over something they can't control or have...
