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 ...
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.
It is thought that the psychotic symptoms within schizophrenia are primarily due to overactive dopamine activity in the mesolimbic area of the brain. [4] Therefore, dopamine supersensitivity may reduce the effect of antipsychotics and increase the brain's response to endogenous dopamine, leading to worsening psychosis. [4]
For years scientists have known that irregular levels of dopamine have some connection to psychosis and are a critical factor in schizophrenia, Alzheimer’s disease and other neuropsychiatric ...
The common dopamine and glutamate models proposed are not mutually exclusive; each is seen to have a role in the neurobiology of schizophrenia. [128] The most common model put forward was the dopamine hypothesis of schizophrenia, which attributes psychosis to the mind's faulty interpretation of the misfiring of dopaminergic neurons. [129]
The risk of enlarged ventricles on brain scan (associated with schizophrenia symptoms and biologically suggestive of Emil Kraepelin's dementia praecox) was greatly increased if the subjects had both a higher genetic load for schizophrenia and lower birthweight. The investigators suggested that in utero insults may specifically stress those with ...
