Schizophrenia Flashcards
psych- family dys- SM
fromm reichman- psychodynamic
mother is cold, rejecting and controlling
creates a family dynamic characterised by tension and secrecy
leads to distrust in person which develops into paranoid delusions
-not used now as it very outdate
family dys- DB
double bind- Bateson (risk factor not the main communication type)
when child does something wrong they are punished by withdrawal of love
they fear they are doing something wrong but receive mixed messages about what this is
leaves them with understanding of world as confusing and dangerous
reflected in symptoms such as paranoid delusions and disorganised thinking
family dys- EE
level of emotion expressed by family towards person with sz
involves:
verbal criticism
hostility- anger and rejection
over involvement- needless self sacrifice
serious source of stress for person
primarily an explanation for relapse but can be a trigger of onset of sz to a person who is already genetically vulnerable
family dys ao3- s
read et al- found that people with Sz were more likely to have insecure attachments to parents
-also found that 69% of men and 59% of women with sz had experienced some type of child physical or sexual abuse
shows link between effect of family/ childhood on sz
Tienari- children with parents with sz (adopted now) are more likely to develop sz than those without, however the genetic link is only shown when the adopted family was rated as disturbed- shows the effect of family dys
practical applications in family therapy and there is evidence for the effectiveness of this so it shows that family dys must be part of the issue
family dys ao3- w
cause and effect- the disruption in family climate may be due to the sz patient in the family rather than the other way round
DB and SM are based on clinical observations of people with sz and interviews with family members, relies on retrospective info which may not be accurate (no systematic evidence)
-lack of evidence to support specific theories (most is general to effect of family)
theory is socially sensitive as it blames the sz on the mother which makes them feel guilty
cog exp DT
involves info processing that doesn’t represent reality
sz associated with a number of different DT
reduced processing in temporal lobe associated with hallucinations
dys though processing in ventral striatum linked with negative symptoms
cog exp MR
frith et al- cog ability to reflect on thoughts and behav
allows us to insight our intentions and intentions of others
eg ability to realise that our own thoughts are being carried out by ourselves rather than anyone else
can explain hallucinations and hearing voices
cog exp CCD
central control dysfunction
inability to suppress automatic thoughts while we perform deliberate actions
disorganised speech and thoughts reflect inability to suppress automatic responses
sz often experience derailment of thoughts, speech triggered by asso with other thoughts
cog exp ao3- s
stirling et al- compared performance on cog tasks in 30 people with sz to controls
stroop task- people have to suppress automatic response to say the colour that is written, and say the colour that it is in
sz patients took twice as long as controls which supports CCD
RWA in CBT- based on faulty cognitive processes
Firth studied 30 sz using PET scans and they showed a reduction in blood flow to frontal cortex (in patients with neg symptoms) associated with making decisions based on info coming in from dif parts of the brain
empirical evidence for cognitive dysfunctions
cog exp ao3- w
doesn’t explain why sz developed in the first place- the origins, only explains what is happening now so is only partial exp
dys thought processing may a result of the Sz rather than a cause
reductionist
bio treatments
based on dopamine hypothesis which says that high dopamine leads to increased severity of Sz
typical- alleviate positive symptoms by blocking DA receptors
side effects incl diabetes and tardive dyskinesia
eg chlorpromazine
atypical- alleviate positive and neg symptoms by blocking DA receptors and regulating serotonin
improve mood so used for patients at risk of suicide
side effects incl weight gain
clozapine
bio treatment ao3- s
barlow and durand- found typical AP were effective in reducing positive symptoms in 60% of cases
Thornley- found that in 1121 ps, chlorpromazine was associated with better overall functioning and reduced symptoms compared to placebos
ch
Bagnall analysed evidence from 232 studies comparing clozapine to placebos and other drugs + found that they were the most effective, even in people who were previously treatment resistant, showed least side effects and fewer people left the treatment early
bio treatment ao3- w
chemical cosh- ethical argument that suggests sz patients are given drugs in hospitals just to calm them down and make them easier to deal with - Monchief
Healey- suggested there are lots of flaws with evidence for effectiveness as they only show short term effectiveness and APs have calming effect on brain so it is easy to say symptoms have been alleviated but it is unclear if the actual psychosis is reduced
side effects of drugs- doesn’t show long term effects of drugs and people’s symptoms often come back after they finish drug treatment
Beng Choo Ho- using APs leads to a reduction in the brain tissue of sz patients
unclear how APs work as low dopamine is linked with increased severity of sz in some parts of the brain and levels of dopamine are reduced very quickly but it takes a long time for sz symptoms to decrease
family therapy
aims to improve communication and interactions in families
usually occurs when a sz patient is returning from psych ward
involves educating the family on the symptoms of sz, reducing conflict and stress
gives the family solutions to problems that may arise
-reduces negative emotions by reducing levels of EE, stress is reduced, less likely to relapse
-finds balance between patient’s needs and the family’s life
family therapy ao3
mcFarlane- concluded that family therapy was one of the most consistently effective treatments for Sz and it reduced relapse rates by 50-60%
benefits the whole family as they all have to deal with the patient, lessens the neg impact the sz patient has on the family + strengthens their ability to help the sz patient
some families may not want to deal with the sz patient as they have already caused enough issues in the family
puts a lot of pressure on the family to deal with sz patient
