Biological explanations of schizophrenia

ao1:

A possible explanation of schizophrenia is that it runs in families with genetic factors playing an important role in the development of the disorder. the risk of the schizophrenia increases among those who are genetically related to people with the disorder .for example there is a much higher risk 48% of an individual developing schizophrenia if their identical twin also has it compared to their ordinary sibling 9% .gorgeous man carried out a study into the role of genetic factors in the development of schizophrenia and found that the more closely related to people are the higher chance of also developing schizophrenia .it is out of food that a combination of genes makes an individual vulnerable to schizophrenia polygenic and that different candidate genes are asserted associated with risk of inheritance.

dopamine is a new transmitter in the brain which transmits messages between you and schizophrenics are thought to have abnormally high levels of dopamine . this is because they have lots of detail receptors which bind and result in more dopamine firing ,leading to positive symptoms of schizophrenia like hallucinations .therefore the dopamine hypothesis suggests that an excess of dopamine in certain regions of the brain is associated with positive symptoms of schizophrenia. Hyperdopamingeria is abnormally low levels of dopamine in the prefrontal cortex of the brain responsible for thinking and decision-making, which is associated with negative symptoms of schizophrenia like avolition. Another biological explanation of schizophrenia is neural correlates abnormalties or brain structure or function that correlate with an experience . for example motivation is related to certain areas of the brain. abnormalities here may be linked to the development of avolition. it was also found that reduce…
