In the third module we begin to discuss the neurochemistry of the disorder as well as common manifestations of those diagnosed with schizophrenia on structural and functional brain MRI scans. First, though, we look at two more client-clinician simulations to explore symptoms and recovery.

Schizophrenia Latent schizophrenia (F21.1), schizophrenic reaction (F21.2), pseudoneurotic schizophrenia (F21.3), pseudopsychopathic schizophrenia (F21.4), “symptom-depleted” schizophrenia (F21.5) are in the Russian version of the ICD-10. They are in the category of “schizotypal” disorder in section F21 of chapter V.
Schizophrenia Schizophrenia and smoking have shown a strong association in studies worldwide. Use of cigarettes is especially high in individuals diagnosed with schizophrenia, with estimates ranging from 80 to 90% being regular smokers, as compared to 20% of the general population. Those who smoke tend to smoke heavily, and additionally smoke cigarettes with high nicotine content. Some evidence suggests that paranoid schizophrenia may have a better prospect than other types of schizophrenia for independent living and occupational functioning. Among people with schizophrenia use of cannabis is also common.
Schizophrenia The term schizophrenia is commonly misunderstood to mean that affected persons have a "split personality". Although some people diagnosed with schizophrenia may hear voices and may experience the voices as distinct personalities, schizophrenia does not involve a person changing among distinct, multiple personalities; the confusion arises in part due to the literal interpretation of Bleuler's term "schizophrenia" (Bleuler originally associated schizophrenia with dissociation, and included split personality in his category of schizophrenia). Dissociative identity disorder (having a "split personality") was also often misdiagnosed as schizophrenia based on the loose criteria in the DSM-II. The first known misuse of the term to mean "split personality" was in an article by the poet T. S. Eliot in 1933. Other scholars have traced earlier roots. Rather, the term means a "splitting of mental functions", reflecting the presentation of the illness.

Schizophrenia A combination of genetic and environmental factors play a role in the development of schizophrenia. People with a family history of schizophrenia who have a transient psychosis have a 20–40% chance of being diagnosed one year later.
Schizophrenia Media coverage relating to violent acts by individuals with schizophrenia reinforces public perception of an association between schizophrenia and violence. In a large, representative sample from a 1999 study, 12.8% of Americans believed that individuals with schizophrenia were "very likely" to do something violent against others, and 48.1% said that they were "somewhat likely" to. Over 74% said that people with schizophrenia were either "not very able" or "not able at all" to make decisions concerning their treatment, and 70.2% said the same of money-management decisions. The perception of individuals with psychosis as violent has more than doubled in prevalence since the 1950s, according to one meta-analysis.
Schizophrenia Many genes are believed to be involved in schizophrenia, each of small effect and unknown transmission and expression. Many possible candidates have been proposed, including specific copy number variations, "NOTCH4", and histone protein loci. A number of genome-wide associations such as zinc finger protein 804A have also been linked. There appears to be overlap in the genetics of schizophrenia and bipolar disorder. Evidence is emerging that the genetic architecture of schizophrenia involved both common and rare risk variation.
Schizophrenia About half of those with schizophrenia use drugs or alcohol excessively.
Simple-type schizophrenia Other names for it are "simple schizophrenia", "simple deteriorative disorder", "schizophrenia simplex, deficit schizophrenia" or "deficit syndrome."
Schizophrenia Individuals with severe mental illness, including schizophrenia, are at a significantly greater risk of being "victims" of both violent and non-violent crime. Schizophrenia has been associated with a higher rate of violent acts, although this is primarily due to higher rates of drug use. Rates of homicide linked to psychosis are similar to those linked to substance misuse, and parallel the overall rate in a region. What role schizophrenia has on violence independent of drug misuse is controversial, but certain aspects of individual histories or mental states may be factors. About 11% of people in prison for homicide have schizophrenia while 21% have mood disorders. Another study found about 8-10% of people with schizophrenia had committed a violent act in the past year compared to 2% of the general population.
Schizophrenia Environmental factors associated with the development of schizophrenia include the living environment, drug use, and prenatal stressors.
Schizophrenia Late adolescence and early adulthood are peak periods for the onset of schizophrenia, critical years in a young adult's social and vocational development. In 40% of men and 23% of women diagnosed with schizophrenia, the condition manifested itself before the age of 19. To minimize the developmental disruption associated with schizophrenia, much work has recently been done to identify and treat the prodromal (pre-onset) phase of the illness, which has been detected up to 30 months before the onset of symptoms. Those who go on to develop schizophrenia may experience transient or self-limiting psychotic symptoms and the non-specific symptoms of social withdrawal, irritability, dysphoria, and clumsiness before the onset of the disease. Children who go on to develop schizophrenia may also demonstrate decreased intelligence, decreased motor development (reaching milestones such as walking slowly), isolated play preference, social anxiety, and poor school performance.
Pediatric schizophrenia Schizophrenia disorders in children are rare. Boys are twice as likely to be diagnosed with childhood schizophrenia. People have been and still are reluctant to diagnose schizophrenia early on, primarily due to the stigma attached to it.
Schizophrenia In the United States, the cost of schizophrenia—including direct costs (outpatient, inpatient, drugs, and long-term care) and non-health care costs (law enforcement, reduced workplace productivity, and unemployment)—was estimated to be $62.7 billion in 2002. The book and film "A Beautiful Mind" chronicles the life of John Forbes Nash, a Nobel Prize–winning mathematician who was diagnosed with schizophrenia.
Sluggish schizophrenia The Soviet model of schizophrenia is based on the hypothesis that a fundamental characteristic (by which schizophrenia spectrum disorders are distinguished clinically) is its longitudinal course. The hypothesis implies three main types of schizophrenia:
Schizophrenia Amphetamine, cocaine, and to a lesser extent alcohol, can result in a transient stimulant psychosis or alcohol-related psychosis that presents very similarly to schizophrenia. Although it is not generally believed to be a cause of the illness, people with schizophrenia use nicotine at much higher rates than the general population.
Catastrophic schizophrenia E.B. Strauss stated that schizophrenia could come about in two ways: either catastrophically or through a series of 'attacks'. Strauss used catastrophic to refer to schizophrenia that ran a rapidly progressing and continuous course. According to Strauss, catastrophic schizophrenia took a similar course to catatonic schizophrenia and hebephrenia, with all three ending in the total collapse into psychosis within two to four years.
Paranoid schizophrenia As of 2013, with the publication of the new DSM-5, the different subtypes of schizophrenia are no longer specified or differentiated from schizophrenia in the manual. Instead, schizophrenia is viewed as one mental disorder with an array of different symptoms. Treatment for people suffering from schizophrenia is based on the type of symptoms that are exhibited in each individual case.
