Schizophrenia Flashcards
Names of the classifications of schizophrenia?
1) . ICD-10.
2) . DSM-5.
Who said the diagnosis of schizophrenia has low reliability?
Cheniaux et al. (2009) =
- 2 psychiatrists independently diagnose 100 patients using the classifications.
- 1 = diagnosed 26 with DSM, 44 with ICD.
- 1 = diagnosed 13 with DSM, 24 with ICD.
What does Cheniaux et al.’s study show about the validity of the classification of schizophrenia?
That it is much more likely to be diagnosed with ICD than DSM.
What did Buckley et al. (2009) find about schizophrenia being co-morbid?
- 50% of schizophrenics have depression.
- 47% have substance abuse.
Schizophrenia is co-morbid.
Who discusses gender bias as a limitation in the diagnosis of schizophrenia?
1). Longenecker et al. (2010) =
Since 1980s, men have been diagnosed more than women.
2). Cotton et al. (2009) =
Women have better interpersonal functioning skills so are better at avoiding diagnosis.
Who’s study demonstrates a concordance rate of schizophrenia in MZ/DZ twins?
Gottesman (1991).
What did Ripke et al. (2014) find in relation to candidate genes?
Studied 37,000 patients =
- found 108 separate genetic variations (candidate genes).
What did Juckel et al. (2006) find about the hyperdopaminergia in the subcortex?
Found a negative correlation between ventral striatum activity and overall negative symptoms.
What did Allen et al. (2007) find about the hypodopaminergia in the prefrontal cortex?
Hallucinations and superior temporal gyrus =
- low levels of activity in superior temporal gyrus and anterior cingulate gyrus = auditory hallucinations.
Who’s study shows that adopted twins from a schizophrenic family may still be at risk of developing schizophrenia?
Tienari et al. (2004).
How did Fromm-Reichmann (1948) explain schizophrenia?
Psychodynamic explanation =
- schizophrenic mother = mothers cause schizophrenia.
Who developed the double-blind theory as a psychodynamic approach to explaining schizophrenia?
Bateson et al. (1972).
Who talked about meta-representations as the cognitive ability to reflect on thoughts and behaviour?
Frith et al. (1992).
Who evaluated the psychodynamic approach to explaining schizophrenia?
1) . Read et al. (2005) =
- 69% of female schizophrenics (in study) had physical/sexual abuse in childhood.
- info gained after diagnosis - could have distorted experience.
2) . Stirling et al. (2006) =
- Stroop Test (colour/words).
- schizophrenics took twice as long to suppress the impulse to read the word and name the colour instead.
Name of the typical antipsychotic?
Chlorpromazine.
