The circumstances of one's social class do not cause the onset of a mental disorder, but rather, an individual's deteriorating mental health occurs first, resulting in low social class attainment. [2] The drift hypothesis is the opposing theory of the social causation thesis, which says being in a lower social class is a contributor to the ...
The downward drift theory may be mainly applicable to schizophrenia; however, it may also apply to other mental illnesses since each is accompanied by a negative stigma. While it can be hard to maintain status once the schizophrenia appears, some individuals are able to resist a downward drift, particularly if they start out at a higher SES.
These rapid evolutionary changes, in some cases, may impede normal development within the social brain. [14] [15] As schizophrenia is foremost a disorder of the consciousness, it has been suggested that schizophrenia exists as an unwanted byproduct of the evolution of the prefrontal cortex and other brain regions constituting the social brain.

'This will turn out to be the most important break in the disease,' the Broad Institute's director Eric Lander said.
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.
Social problems such as long-term unemployment, poverty, homelessness, exploitation, and victimization are commonly correlated with schizophrenia. [ 25 ] [ 26 ] Compared to the general population, people with schizophrenia have a higher suicide rate (about 5% overall) and more physical health problems , [ 27 ] [ 28 ] leading to an average ...
Social defeat is a very potent stressor and can lead to a variety of behavioral effects, like social withdrawal (reduced interactions with conspecifics), lethargy (reduced locomotor activity), reduced exploratory behavior (of both open field and novel objects), anhedonia (reduced reward-related behaviors), decreased socio-sexual behaviors ...
One anthropologist putting forward this theory, Crow, states that schizophrenia is a result from incomplete hemispheric specialization due to selection of genes relating to language. While another scientist, Burns, follows that schizophrenia is related to modified cortical connectivity which is vital for the development of the 'social brain. [3]
