Overall, people who live with schizophrenia have lower IQ scores than those who don't experience the condition. There are people who live with schizophrenia who have higher IQ scores, and they appear to have somewhat different symptoms than those with lower scores.
Intelligence Decline (ID) in Schizophrenia
The lifetime risk of the disorder is approximately 0.5–1% (2). The disorder is characterized by a wide spectrum of symptoms, such as delusions, hallucinations, blunted affect and withdrawal, cognitive impairments, as well as subtle decline in intelligence.
The average IQ is around 100 points. However, for people who may develop a psychotic illness, such as those with a microdeletion of chromosome 22, the average drops to 70-80 points.
For example, meta-analyses show an average premorbid 8-point IQ deficit (0.50 SD) among those who later develop schizophrenia (3) but a 14-21 point IQ deficit (0.90-1.40 SD) among first-episode and chronic schizophrenia patients (1, 4, 5).
According to several studies, people with intellectual disability have increased risk of being diagnosed with a wide variety of psychiatric disorders [9,10,11,12]. In addition, Koenen et al. [9] found that IQ below 85 in childhood was associated with increased risk of schizophrenia later in life.
The average IQ of paranoid patients was 74.3, of catatonic patients 64.8, of hebephrenic patients 59.2, and of those with schizophrenia simplex 57.4. Most cases with IQ = 0 related to the group with schizophrenia simplex.
Genetics. Your genes and your environment both play a role. But your chances of getting schizophrenia may be more than six times higher if one of your parents, siblings, or another close relative has it.

In 1978, Nash was awarded the John von Neumann Theory Prize for his discovery of non-cooperative equilibria, now called Nash equilibria. As a result of Nash's illness, he adopted unhealthy practices that did not help him cope with schizophrenia.
Studies have also found that higher IQ is associated with more mental illness, including depression, anxiety, and bipolar disorder.
Unfortunately, most people with schizophrenia are unaware that their symptoms are warning signs of a mental disorder. Their lives may be unraveling, yet they may believe that their experiences are normal. Or they may feel that they're blessed or cursed with special insights that others can't see.
As the severity of the schizophrenic defect in the form of negativism, apathy, and abulia increased, changes in emotional and cognitive forms of self-awareness intensified.
Some researchers believe that problems with brain development may be partly responsible for schizophrenia. Others believe that inflammation in the brain may damage cells that are used for thinking and perception. Many other things could also play a role, including: Exposure to viruses before birth.
Previous studies using the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT) revealed significant performance deficits across all areas of Emotional Intelligence (EI) in schizophrenia patients compared to healthy controls.
Individuals with Borderline Personality Disorder (BPDs) become overwhelmed and incapacitated by the intensity of their emotions, whether it is joy and elation or depression, anxiety, and rage. They are unable to manage these intense emotions.
Schizophrenia and Antisocial Personality Disorder are the most common diagnoses amongst serial killers.

There is no one genetic cause of schizophrenia; no one has the “schizophrenia gene.” Rather, there are what the Mayo Clinic calls “a complex group of genetic and other biological vulnerabilities.” A person isn't born with schizophrenia, but there are certain neurochemical conditions that make them candidates for its ...
Thoughts and speech may become jumbled or confused, making conversation difficult and hard for other people to understand. Some people describe their thoughts as being controlled by someone else, that their thoughts are not their own, or that thoughts have been planted in their mind by someone else.
