Are schizophrenic (psychosis-spectrum) symptoms just a means to deal with deprivation from basic human needs?
Obviously, the propensity towards schizophrenia is largely considered to be genetic. But what exactly provokes the illness?
Point 1: Sleep deprivation provokes psychotic symptoms in people.
In fact, it can and will provoke psychotic symptoms in healthy people after multiple days have passed.
Point 2: Unhealthy nutrition predicts schizophrenia.
Prenatal malnutrition - 2x risk of schizophrenia (although this is a risk factor for many things)
Low childhood BMI - 2.3x risk of psychosis later
Low D and folate - common in first episode psychosis
Point 3: Sensory deprivation provokes hallucinations.'
This also happens in healthy people because the brain constantly expects reliable input signals. So we can assume that unhealthy people fail to interpret their signals for some reason - whether it's organic damage or something in their environment.
Point 4: Denial of one's own painful reality.
There's an old theory on the origin of schizophrenia - the schizophrenogenic mother - a cold dominant parent aiming to control her child's behavior.
The idea of a schizophrenogenic mother emerged from 11 families taking part in the research of schizophrenia and they had a few points in common:
* The child’s feelings or experiences were denied
* Contact with outsiders was restricted
* Strict, contradictory rules were enforced
At the same time, MMPI scale 8, one that aimed to measure the test-taker's schizophrenia, found that it doesn't only correlate to schizophrenia, but also emotional abuse and neglect, sexual abuse, constant destruction of one's self-worth. (as well as some brain damage and genetic factors)
In a way, an abusive environment can mimic point 3: sensory deprivation, a lack of signals the person can comprehend. Likewise, people who suffered through loneliness as a child are much likelier to experience hallucinations later on.
