The Truth about Schizpohrenia

Better Essays
Schizophrenia, a mental disorder that is linked to genetic and environmental factors, manifests itself in a variety of symptoms over time. Schizophrenia makes telling the difference between reality and non-reality difficult. Schizophrenia also makes it troublesome for sufferers to think clearly or respond normally or appropriately in social situations. There is scientific evidence demonstrating a variety of biological and environmental aspects that contribute to the development of schizophrenia.

First, the strongest evidence points to genetic factors that contribute to the risk of developing schizophrenia. Michael Green, author of Schizophrenia Revealed, states “In the not-so-distant past, it was possible to have an honest difference of opinion about this point but not anymore.” (54) It is estimated that the hereditary chances of this disorder are between 74 percent to almost 90 percent, making genetics the most important factor for developing schizophrenia (52). The National Institute of Mental Health author of “Schizophrenia” adds “The illness occurs in 10% of people who have first-degree relatives with the disorder; such as a parent, brother, or sister.” Having a second degree relative has also shown a higher than average development of the


disorder, with those at highest risk being an identical twin of a person diagnosed with schizophrenia. Sun, Han and Zhao, authors of "Gene-and evidence-based candidate gene selection for schizophrenia and gene feature analysis," think several genes are shown to be associated with the schizophrenia, but no one gene has been identified or said to cause the disorder itself. Studies suggest that schizophrenia is the product of a certain gene that chemically malfunctions. T...
