Although the results do not reflect the molecular events that occurred during early neural development or evolution, they provide insight into the molecular network that underlies the impaired cognitive and social scenarios that act in the schizophrenic brain, and further suggest that self-domestication, language processing, and schizophrenia ...
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.
Symptoms of schizophrenia often appear soon after puberty, when the brain is undergoing significant maturational changes. Some investigators believe that the disease process of schizophrenia begins prenatally, remains dormant until puberty, then follows a period of neural degeneration that causes the symptoms to subsequently emerge.

This model hypothesizes schizophrenia to be an extreme example of abnormal and undesirable mental and behavioral traits that function as fitness indicators. In this model, the fitness indicator related to schizophrenia is courtship ability, which involves verbal and behavioral aspects.
Schizophrenia affects around 0.3–0.7% of people at some point in their life. [ 19 ] [ 14 ] In areas of conflict this figure can rise to between 4.0 and 6.5%. [ 256 ] It occurs 1.4 times more frequently in males than females and typically appears earlier in men.
Schizophreniform disorder is a type of mental illness that is characterized by psychosis and closely related to schizophrenia.Both schizophrenia and schizophreniform disorder, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), have the same symptoms and essential features except for two differences: the level of functional impairment and the duration of symptoms.
However, schizophrenia itself is regarded as a breakdown process, quite distinct from the continuously distributed trait of schizotypy, and forming a second, graded continuum, ranging from schizotypal personality disorder to full-blown schizophrenic psychosis.
The other hypothesis, which has an unknown cause, is the capacity to think in minimal-educated families where the children in these families are more likely to have schizophrenic reactions. [ 3 ] In their book, Schizophrenia and the Family (1965), Lidz, Fleck and Alice Cornelison compiled findings of what remains perhaps the most detailed ...
