... Hemmings, 1989). Some researchers believe that problems with these genes, which are either from mutated chromosomes, or recessive genes, provide the explanation for the cause of schizophrenia. The genetic explanation for the cause of schizophrenia has been supported by studies of 1) relatives of people with schizophrenia who are adopted, 2) twins with this disorder, 3) people with schizophrenia ... -like illness, which expresses itself in traits such as over protectiveness or hostility (Faraone, 1997). Thus, any so-called "schizophrenogenic" characteristics may also be a result of the ge...

... premorbid neurodevelopmental abnormalities, more cytogenetic anomalies, and potentially greater family histories of schizophrenia and related spectrum disorders" (Kumra). This type of evidence suggests that children with schizophrenia have a much stronger genetic contribution toward the disorder than adults (Kumra). Patients with childhood-onset schizophrenia often have a poorer outcome in comparison to those who do not develop the disease until adulthood, especially in ... learned from children with this disorder when comparing them to adults suffering similar symptoms. If researchers...

... of schizophrenia or a related spectrum disorder become even greater if both parents are diagnosed (Olin and Mednick, 1996). Numerous twin studies diagnosed with schizophrenia have been used to demonstrate the genetic link. However, twin studies have also evidenced environmental effects - for example, researchers were unable to locate matching phenotype expressions for the genetics hypothesized in twins concordant for schizophrenia (Proceedings of ... ...
