Combination of both…? However, it will be shown that (either physcolgoical or bio) are more convcing or there is more evidence for this.
Say which explanations I am discussing..
One biological explanation for schizophrenia are genetic factors. It has been known that psychotic symptoms run in families which may well be some form of inherited predisposition (re phrase!! Pychopathology, page 249) There is evidence to reinforce that the more closely related one is to someone with Schizophrenia the more likely one is to develop it. For example, recent studies …show more content…
The discovery of antipsychotic drugs have helped alleviate the symptoms of psychosis and through this discovery it was shown that these drugs blocked the brains dopamine receptor sites, and therefore reinforcing that excess dopamine is clearly an explanation for the diagnosis of schizophrenia. (APPLIED PHYSCOLOHY PG 72) The reverse can for example ampethamines and similar drugs increase the amount of dopamine in the brain and can cause symptoms which replicate those present in psychosis, particularly after large doses or continued
