Schizoaffective disorder

[18] Diagnosis of schizoaffective disorder is based on DSM-5 criteria, which consist principally of the presence of symptoms of schizophrenia, mania, and depression, and the temporal relationships between them.

[5][20][non-primary source needed] Outcomes for people with DSM-5 diagnosed schizoaffective disorder depend on data from prospective cohort studies, which have not been completed yet.

Symptoms of mania include elevated or irritable mood, grandiosity (inflated self-esteem), agitation, risk-taking behavior, decreased need for sleep, poor concentration, rapid speech, and racing thoughts.

[27] The more often cannabis is used, particularly in early adolescence, the more likely a person is to develop a psychotic illness,[28][29][30] with frequent use being correlated with double the risk of psychosis and schizoaffective disorder.

[31] A 2009 Yale review stated that in individuals with an established psychotic disorder, cannabinoids can exacerbate symptoms, trigger relapse, and have negative consequences on the course of the illness.

Delirium should be ruled out, which can be distinguished by visual hallucinations, acute onset and fluctuating level of consciousness, indicating other underlying factors which includes medical illnesses.

I want to call attention to the fact that some persons with a family history of even the subtler forms of bipolar disorder or psychosis are more vulnerable than others to the mania- or psychosis-inducing potential of antidepressants, stimulants and sleeping medications.

[54] There are several theorized causations for the onset of Schizoaffective disorder, including, genetics, general brain function, like chemistry, and structure, and stress.

Mistakes in this stage include: The most widely used criteria for diagnosing schizoaffective disorder are from the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders-5.

These two changes are intended by the DSM-5 workgroup to accomplish two goals:[5] If the schizoaffective diagnosis is used less often, other diagnoses (like psychotic mood disorders and schizophrenia) are likely to be used more often; but this is hypothetical until real-world data arrive.

[5] An initial diagnosis of schizoaffective disorder during time spent at a psychiatric inpatient facility was stable at 6-month and 24-month follow ups for only 36% of patients.

A core concept in modern psychiatry since DSM-III was released in 1980, is the categorical separation of mood disorders from schizophrenia, known as the Kraepelinian dichotomy.

[66] The Kraepelinian dichotomy was not used for DSM-I and DSM-II because both manuals were influenced by the dominant psychodynamic psychiatry of the time,[67] but the designers of DSM-III wanted to use more scientific and biological definitions.

[66] According to this genetic evidence, the Kraepelinian categorical separation of mood disorders from schizophrenia at the foundation of the current classification and diagnostic system is a mistaken false dichotomy.

[66][69] The dichotomy at the foundation of the current system forms the basis for a convoluted schizoaffective disorder definition in DSM-IV that resulted in excessive misdiagnosis.

[66][69] The categorical diagnostic manuals do not reflect reality in their separation of psychosis (via the schizophrenia diagnosis) from mood disorder, nor do they currently emphasize the actual overlap found in real-life patients.

[66][69] Thus, they are likely to continue to introduce either-or conceptual and diagnostic error, by way of confirmation bias into clinicians' mindsets, hindering accurate assessment and treatment.

[66][69] After enough research is completed and data exists, future diagnostic advances will need to either eliminate and replace, or soften and bridge, the hard categorical separation of mood disorders from schizophrenia; most likely using a spectrum or dimensional approach to diagnosis.

[5][69] More parsimonious definitions than the current one were considered by Carpenter and the DSM-5 workgroup:[5] One option for the DSM-5 would have been to remove the schizoaffective disorder category and to add affective [or mood] symptoms [that is, mania, hypomania, mixed episode, or depression] as a dimension to schizophrenia and schizophreniform disorder or to define a single category for the co-occurrence of psychosis and mood symptoms.

This option was extensively debated but ultimately deemed to be premature in the absence of sufficient clinical and theoretical validating data justifying such a … reconceptualization.

[U]ltimately a more ... dimensional approach [to assessment and treatment] will be required.The field of psychiatry has begun to question its assumptions and analyze its data in order to merge closer with evidence-based medicine.

[56] From a scientific standpoint, modern clinical psychiatry is still a very young, underdeveloped medical specialty because its target organ, the human brain, is not yet well understood.

[53] While various medications and treatment options exist for those diagnosed with schizoaffective disorder, symptoms may continue to impact a person for their entire lifespan.

[26]Schizoaffective disorder can affect a person's ability to experience a fulfilling social life and they may also exhibit difficulty forming bonds or relationships with others.

This rehabilitation method focuses on solving community integration problems such as obtaining and keeping housing and increasing involvement in positive social groups.

[81] Though not approved for treatment use by the FDA, research suggests that Clozapine may also be effective in treating schizoaffective disorder, particularly in those resistant to initial medication.

[83] When combined with cognitive therapy, Clozapine has been found to decrease positive and negative symptoms of psychosis at a higher rate in schizoaffective individuals.

[11][92] The term schizoaffective psychosis was introduced by the American psychiatrist Jacob Kasanin in 1933[93] to describe an episodic psychotic illness with predominant affective symptoms, that was thought at the time to be a good-prognosis schizophrenia.

[94] In 1959, psychiatrist Kurt Schneider (1887–1967) began to further refine conceptualizations of the different forms that schizoaffective disorders can take since he observed "concurrent and sequential types".

[5][99] The poor prognosis for DSM-IV schizoaffective disorder was not based on patient outcomes research, but was caused by poorly defined criteria interacting with clinical tradition and belief; clinician enculturation with unscientific assumptions from the diagnosis' history (discussed above), including the invalid Kraepelinian dichotomy;[66][69] and by clinicians being unfamiliar with the scientific limitations of the diagnostic and classification system.

Emil Kraepelin's dichotomy ( c. 1898 ) continues to influence classification and diagnosis in psychiatry.
Karl Kahlbaum (1828–1899)
Emil Kraepelin (1856–1926). Embracing the Kraepelinian dichotomy in DSM-III in 1980, while a step forward from psychodynamic explanations of the disorder, introduced significant problems in schizoaffective disorder diagnosis, as explained recently by the DSM-5 workgroup.
