  • 1. Social and Biological Causes for Schizophrenia By: Trista Foster Lindenwood University
  • 2. Definition . "Schizophrenia is a severe brain disorder that usually produces a lifetime of disability and emotional distress for affected individuals" (Lewis & Lieberman, 2000; Lewis and Levitt, 2002). It effects 1% of the population
  • 3. Onset of Schizophrenia Schizophrenia’s most prevalent symptoms begin in early adulthood. Early onset Schizophrenia is just as severe: Lewis and Levitt (2002) state that children and adolescence with schizophrenia show signs such as: isolation, low social confidence, and social anxiety.
  • 4. Social Causes of Schizophrenia Cantor-Gree (2007) states that social situations can have an etiologic role for the onset and development of schizophrenia. – Culture – Urbanization – Social Defeat – Migration – Social Inequality and Adversity
  • 5. Social Causes Continued… The environment that a person grows up in can heavily affect the onset of schizophrenia: – According to Cantor- Graae (2007) stressors in the home that contribute to stressors that can lead to schizophrenia are: single parent household, rental apartments, unemployment, and the receiving of welfare.
  • 6. Biological Causes of Schizophrenia Gender – . "...the median age at onset differed between the sexes: the males had an earlier onset (mean=27.8 years) than the females (31.5 years) "Gorwood, Leboyer, Jay, Payan, & Feingold, 1995)
  • 7. Biological Causes Continued…. Family History – . Gorwoodm et al., (1995) propose that females with no family history are diagnosed with schizophrenia later than females with family history, and males with or without a family history of schizophrenia.
  • 8. Biological Causes Continued…. Neuroscience – "Endophenotypes are quantative traits (pathophysiological markers) that share a substantial genetic component with the clinical disorder" (Rijisdijk et al., 2005). – Stress can also alter the amount of chemical being produced in the brain
  • 9. In Conclusion There is not certain cause for schizophrenia, but it can better be explained from a social and biological viewpoint. The three greatest suspects for the onset and cause are genetics, stress, and environment.
