  1. 1. Social and Biological Causes for Schizophrenia By: Trista Foster Lindenwood University
  2. 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. 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. 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. 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. 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. 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. 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. 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.
