Dopamine supersensitivity may be caused by the dopamine receptor D 2 antagonizing effect of antipsychotics, causing a compensatory increase in D 2 receptors within the brain that sensitizes neurons to endogenous release of the neurotransmitter dopamine. Because psychosis is thought to be mediated—at least in part—by the activity of dopamine ...
The dopamine hypothesis of schizophrenia or the dopamine hypothesis of psychosis is a model that attributes the positive symptoms of schizophrenia to a disturbed and hyperactive dopaminergic signal transduction. The model draws evidence from the observation that a large number of antipsychotics have dopamine-receptor antagonistic effects. The ...
To make a diagnosis of schizophrenia other possible causes of psychosis need to be excluded. [176]: 858 Psychotic symptoms lasting less than a month may be diagnosed as brief psychotic disorder, or as schizophreniform disorder. Psychosis is noted in Other specified schizophrenia spectrum and other psychotic disorders as a DSM-5 category.

A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and have been used in treating schizophrenia , bipolar disorder , and stimulant psychosis . [ 1 ]
Certain medications such as dopamine agonists are not used, as they may worsen psychotic symptoms to those taking neuroleptic drugs. If the EPS are induced by an antipsychotic , EPS may be reduced by decreasing the dose of the antipsychotic or by switching from a typical antipsychotic to an (or to a different) atypical antipsychotic , such as ...

The causes of schizophrenia that underlie the development of schizophrenia, a psychiatric disorder, are complex and not clearly understood.A number of hypotheses including the dopamine hypothesis, and the glutamate hypothesis have been put forward in an attempt to explain the link between altered brain function and the symptoms and development of schizophrenia.
