1

Positive symptoms include...

1

whose study indicates that schizophrenic patients jump from topic to topic in conversation?

1

Negative symptoms include...

1

Paranoid schizophrenics have hallucinations and delusions about grandeur or persecution

1

Catatonic patients have disorganised speech

1

Disorganised schizophrenic patients have disorganised speech, and thoughts. Their behaviour is bizarre. They have flat effect, social withdrawal and avolition

1

1

Name three issues with diagnosing schizophrenia.

1

Who said that the term 'schizophrenic' is a form of social oppression and influences how people behave and how people react to 'schizophrenic' people.

1

Szasz - is an anti-labeller who

1

Labelling theory says there is poor validity in diagnosis of schizophrenia

1

A criticism of labelling theory is that it doesn't explain where the behaviour came from in the first place. It explains the maintenance through self fulfilling prophecy.

1

In Rosenhans study he sent 8 ( healthy, sick ) people to make appointments in hospitals using the wors '( thud, bang )', '( hollow, full )' and '( empty, filled )'. Once admitted they all acted ( normally, schizophrenic ). All were diagnosed as schizophrenic despite being healthy. They were treated ( differently, the same ) because they were seen as schizophrenia. They all left with a in remission diagnosis. This study shows how people behave differently to 'schizophrenics' and how easily ( misdiagnosis, diagnosis ) occurs. Also it shows how the label is hard to get rid of.

1

The biological approach says that there is a genetic predisposition for schizophrenia

1

The twin study by Gottesman and Shields found ( 48, 56, 19 )% concordance rates for MZ twins and ( 17, 12, 90 )% for DZ twins. Therefore because the MZ ( share more, have less shared DNA ) DNA the fact that they have higher concordance rates indicates a ( genetic, environmental ) link. A criticism of this study is that the higher concordance rate in MZs could be due to a very ( similar, different ) environment. Also if schizophrenia is due to genes alone, the concordance rate should be ( 100, 0 )%.

1

In a adoption study by ( Heston, Gottesman and Shields ), ( 16, 50, 15 )% of the children ,from 47 schizophrenic mothers, who had been adopted at birth had schizophrenia. This is much higher than the ( 1, 10, 50 )% population level. Therefore it seems that schizophrenia is ( hereditary, the result of environemental factors ). This is more conclusive than the twin study by ( Gottesman and Shields, Heston ) because the children ( didn't share, shared ) the same environment with the mother. However this study suffers from a ( small sample size, low ecological validity ).

1

The neurochemical explanation for schizophrenia suggests that excess dopamine causes exessive neural activity (positive symptoms)

1

There is ❌ evidence for the dopemine hypothesis including; Post ❌ showing excess dopemine, ❌ studies (cocaine causes positive symptoms and heightens dopemine activity), ❌ drugs reduce dopemine and positive symptoms.

According to biologists, abnormal brain structures cause schizophrenia. Weyandt found enlarged ventricles correlate with negative symptoms

1

Who found enlarged ventricles correlate with negative symptoms?

1

Expressed emotion belongs to the ( family dysfunction, biological, labelling ) explanation for schizophrenia. This is a ( qualitative level, quantitative level ) of the amount of emotion displayed within a family. HIgh expressed emotion means there are high levels of ( hostility, calm ), ( disapproval, approval ) and ( criticism, support ). Often family members who act like this think they are being helpful.

1

Nomura said if a recovering schizophrenic returns home to a family with high EE they are more likey to relapse to a highly active phase

1

Evidence to support Nomura's theory that if a recovering schizophrenic returns home to a family with high EE they are more likey to relapse to a highly active phase, comes from Butzlaff and Holey

1

Butzlaff and Holey found ( 70, 50, 90 )% of people returning home to a ( high, low ) expressed emotion family relapsed within a ( year, month ).

1

Bateson said when children are put in a ( no win, win-win ) situation by parents, a ( double, triple ) bind, they may develop schizophrenia if they don't find a way out of it. They develop symptoms such as ( flat effect, hallucinations ) as a logical response to their situation

1

Schiffman said 'Patterns of ( communication, fabric ) and relationships have been identified as ( stress, chill ) factors causing schizophrenia'. This includes double ( bind, whiskey ) and ( high, low ) expressed emotion.

1

The most effective treatment is drug therapy alone.

1

A strength of medication in an institution is that dosage cannot be monitored

1

Institutions provide a safe environment for patients.

1

Institutions cause self fulfilling prophecies.

1

The artificial environment of an institution means they learn to cope with the disorder in the real world.

1

Name a conventional antipsychotic drugs

1

All conventional antipsychotic drugs reduce the firing of dopemine

1

Chlorpromazine must be taken regularly with or without symptoms or they will return with greater severity.

1

Who's study found just 6 weeks of treatment with antipsychotic drugs showed significant improvement in 75% of patients.

1

Conventional drugs cause what side effects? Severe muscle

1

Name an a-typical antipsychotic drug

1

Atypical drugs reduce not only positive symptoms but also negative symptoms.

1

About ( 25, 75 )% of sufferers do not respond to ( conventional, atypical ) drugs. These people often respond to ( atypical, conventional ) drugs.

1

A problem with antipsychotic drugs is that they are reductionist.

1

Strengths of antipsychotic drugs in institutions include-stopping revolving door syndrome and a safer environment.

1

Weaknesses of medication within an institution include - an ( artificial, accurate ) environment ( doesn't help, helps ) the patient to establish reality - causes self fulfilling prophecy
