Document Summary
Schizophrenia and the dsm-5: the dsm-5 requires that symptoms last at least six months for the diagnosis of schizophrenia to be made. Schizoaffective disorder comprises a mixture of symptoms of schizophrenia and mood disorders: a person with delusional disorder is troubled by persistent delusions, these can be delusions of persecution or jealousy, grandiose delusions, delusions of erotomania and somatic delusions. Genetic factors: a large amount of research supports the idea that schizophrenia has a genetic component. Family, twin and adoption studies support that genetic factors play a role in schizophrenia. Family studies: an important issue is that schizophrenia shares its inheritance with a range of other mental disorders. Children of parents with schizophrenia are at an increased risk of schizophrenia but also bipolar disorder and other psychiatric illnesses. It has been estimated that while the genetic liability for schizophrenia accounted for 81% of the risk, there is an effect for the shared environment of 11% for twins.
