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.
