diagnosis
Co-morbidity Two or more conditions occur simultaneously
Symptom overlap The same symptoms occur within different conditions
Two psychiatrists independently diagnosed 100
Cheniaux et al (2009)
patients using two different assessments
Investigated those with schizophrenia and found they
Buckley et al (2009)
were likely to also suffer from another condition
Schizophrenia runs in families. Probability of
Gottesman (1991) schizophrenia = 48% between MZ twins, 46% if both
parents had it and 10% between DZ twins.
Children adopted from 19,000 Finnish mothers at birth.
More likely to develop schizophrenia when biological
Tienari et al (2004) relatives had it, but not when adoptive parents did.
High EE levels also implicated in development, but
only for those with a genetic risk.
, Meta-analysis of genome studies. Genetic make-up of
37,000 patients compared to 113,000 controls - 108
Ripke et al (2014)
candidate genes associated with increased risk of
schizophrenia
Hyperdopaminergia High levels of dopamine in the brain's subcortex
Hypodopaminergia Low levels of dopamine in the brain's cortex
Drugs that increase levels of dopamine made
Curran et al (2004) schizophrenia worse and induce schizophrenia like
symptoms in non-schizophrenics
Low levels of dopamine in prefrontal cortex thought
Goldman-Rakik et al
to have a role in causing negative symptoms of
(2004)
schizophrenia
High levels of glutamate contibute to symptoms of
Moghaddam and Javitt schizophrenia. The dopamine hypothesis is
(2012) reductionist as it doesn't consider other
neurotransmitters
Patterns of structure or activity in the brain that occur
Neural Correlates
in conjunction with an experience
Participants listened to recordings of speech and had
Allen et al (2007) to identify if it was their own or not. MRI's used to scan
brain.
Hallucinating schizophrenics made more errors in
voice recognition and showed lower levels of activity
Allen et al (2007)
in the superior temporal gyrus and the anterior
cingulate gyrus compared to controls
Conducted a study involving reward anticipation on 10
Juckel et al (2006)
schizophrenic males and a matched control group.
Found healthy males had higher levels of activity in
the ventral striatum (involved in reward anticipation)
Juckel et al (2006)
than those who were schizophrenic. The lower the
activity the worse the symptoms of schizophrenia.
