When it became evident that the disorder was not a degenerative dementia, it was renamed schizophrenia by Eugen Bleuler in 1908.The word schizophrenia translates as splitting of the mind and is Modern Latin from the Greek words schizein (σχίζειν, to split) and phrēn, (φρήν, mind) Its use was intended to describe the separation of function between personality, thinking, memory, and perception.In the early 20th century, the psychiatrist Kurt Schneider categorized the psychotic symptoms of schizophrenia into two groups – hallucinations and delusions. The hallucinations were listed as specific to auditory and the delusions included thought disorders. These were seen as important symptoms, termed first-rank. The most common first-rank symptom was found to belong to thought disorders. In 2013 the first-rank symptoms were excluded from the DSM-5 criteria; while they may not be useful in diagnosing schizophrenia, they can assist in differential diagnosis.Subtypes of schizophrenia – classified as paranoid, disorganized, catatonic, undifferentiated, and residual – were difficult to distinguish and are no longer recognized as separate conditions by DSM-5 (2013) or ICD-11. Breadth of diagnosis
Before the 1960s, nonviolent petty criminals and women were sometimes diagnosed with schizophrenia, categorizing the latter as ill for not performing their duties within patriarchy as wives and mothers. In the mid-to-late 1960s, black men were categorized as "hostile and aggressive" and diagnosed as schizophrenic at much higher rates, their civil rights and Black Power activism labeled as delusions.In the early 1970s in the US, the diagnostic model for schizophrenia was broad and clinically based using DSM II.

The antipsychotic clozapine is also associated with thromboembolism (including pulmonary embolism), myocarditis, and cardiomyopathy. Psychosocial interventions
A number of psychosocial interventions that include several types of psychotherapy may be useful in the treatment of schizophrenia such as: family therapy, group therapy, cognitive remediation therapy (CRT), cognitive behavioral therapy (CBT), and metacognitive training. Skills training, and help with substance use, and weight management – often needed as a side effect of an antipsychotic – are also offered. In the US, interventions for first episode psychosis have been brought together in an overall approach known as coordinated speciality care (CSC) and also includes support for education. In the UK care across all phases is a similar approach that covers many of the treatment guidelines recommended. The aim is to reduce the number of relapses and stays in hospital.Other support services for education, employment, and housing are usually offered. For people with severe schizophrenia, and discharged from a stay in hospital, these services are often brought together in an integrated approach to offer support in the community away from the hospital setting. In addition to medicine management, housing, and finances, assistance is given for more routine matters such as help with shopping and using public transport.
