Q

How is a diagnoses made using the ICD 10?

Q

what is the aim of Rosenhans study

A

to demonstrate that psychiatrists were unable to distinguish the sane from insane.

50
Q

what was the procedure of rosenhans study

3 females and 5 males presented themselves at psych hospitals hearing same sex, unfamiliar voice saying ‘thud’ and ‘empty’
once admitted they acted normally and kept observations

51
Q

what were the results of rosenhans study

7 diagnosed with Sz and 1 with bipolar.
average stay was 19 days and 30% of actual patients became suspicious.

52

that clinicians are unable to distinguish the sane from the insane

53
Q

what is the contemporary study for Sz

A

Carlsson et al (2000)

54
Q

what was the aim of Carlsson’s study

A

to review evidence for and against the dopamine hypothesis of Sz
and explore the role of other neurotransmitters.

55
Q

what does Carlsson say ‘beyond dopamine’

A

it is unlikely that D is the only neurotransmitter that is associated with Sz, glutamate found in PCP induces Sz symptoms.

56
Q

what does Glutamate do? - Carlsson

A

affects the release of GABA which acts as a ‘brake’ to reduce D activity

57
Q

what are symptoms of unipolar depression

A

-feeling hopeless
-suicidal thoughts
-insomnia/hypersomnia
-loss of appetite

58
Q

according to the DSM what are the requirements for diagnoses of depression

A

must present at least 5 symptoms for 2 weeks or longer

59
Q

what are somatic symptoms

A

changes to physiological patterns such as sleep

60
Q

what are prevalence rates

A

the number of people in a given population that have the disorder at any one time

61
Q

whatare some features of depression

A

-can occur at any age
- 3.3% in 2014of the population have it which is an increase from 2.7 in 2007
-more common in women than men
-23% of women getting treated for ovarian cancer have depression

62
Q

weaknesses of diagnoses of depression

A
  • is unreliable, full agreement pf diagnoses between clinicians is between 4-15%
    -cultural difference, western clinicians may incorrectly diagnose
63
Q

strengths of diagnoses of depression

A

-Shankman found substantial reliability of diagnoses when using the SCID to diagnoses severity of major depression

64
Q

what is the monoamine depletion theory in depression

A

low levels of monoamines lead to depression.

65
Q

what are the three monoamines

A

serotonin, dopamine and noradrenaline

66
Q

what is a reason for low levels of monoamines

A

caused because the reuptake mechanism recaptures the neurotransmitters before they have a chance to reach the receptor

67
Q

what is receptor sensitivity in depression

A

that drugs to not increase the level of neurotransmitters rather they increase the sensitivity of the receptors

68
Q

what is the BDNF hypothesis in depression

A

a chemical that feeds neurons with nutrients. the lower the chemical in the hippocampus and prefrontal cortex, the more severe depression

69
Q

what does BDNF stand for in depression

A

brain derived neurotrophic factor

70
Q

how does BDNF link depression and stress

A

a gene for BDNF is switched off when stressed leading to shrinkage or death which is observe in depression

71
Q

strengths of the monoamine hypothesis in depression

A

-made development in biochemistry and treatments to improve peoples quality of life
-evidence to support BDNF in post mortem brains, showed low levels of BDNF of people who has depression

72
Q

weaknesses of the monoamine hypothesis in depression

A

-reductionist
-there is a delay in drug taking and symptom improvement

73
Q

what is becks negative triad for depression

A

1-negative view of one self
2-negative views of the world
3-negative views about the future.

74
Q

what is Ellis’ ABC model for depression

A

Activating event
Belief about the event (irrational)
Consequence, anxiety

75
Q

explanation of Becks cognitive explanation for depression

A

irrational thinking is a symptom of depression. if someone believes they are disliked they will reinforce negative views of themselves and their fore their future and the world

76
Q

strengths of the cognitive explanation for depression

A

-Brown showed that there is a lot of evidence that link negative thoughts and depression
-have lead to effective therapies

77
Q

what is the basis for the cognitive explanation for depression

A

irrational thinking

78
Q

weaknesses of the cognitive explanation for depression

A

-Brown found symptoms rather than causes
-evidence from CBT show a fault in information processing not negative thought
- no identifiable risk factors

79
Q

what do monoamine oxidase inhibitors do in depression

A

they remove enzymes that reuptake monoamines so they raise the levels of monoamines in the synapse

80
Q

what do selective serotonin reuptake inhibitors do in depression

A

they block reuptake transporters so less serotonin is recaptured

81
Q

what do serotonin-noradrenaline reuptake inhibitors do in depression

A

block both the rue-taker transporters for serotonin and noradrenaline

82
Q

what do noradrenergic and specific serotonergic antidepressants do in depression

A

they bloc certain receptors so there is increased activity at certain receptor points that are associated with depression if reduces serotonin activity is seen

83
Q

strengths of a biological treatment for depression

A

-meta analysis (Cipriani) found that these antidepressants did better than the placebo
-drug treatment authenticated depression as a medical disorder and not a person who is lazy reducing stigma

84
Q

weaknesses of a biological treatment for depression

A

-help relieve symptoms but do not treat the cause making therapy more helpful
-induvidual difference inhibit the equality of antidepressants to all patients

85
Q

What was the aim of carlsson

A

Provide more of an explanation for Sz that the dopamine hypothesis

86
Q

What were the conclusions of Carlsson

A

Neurotransmitters aside from dopamine need more research

87
Q

What were the results of carlsson

A
  • as glutamate lowered dopamine increased
  • glutamate failure in the cerebral cortex lead to negative symptoms
88
Q

strengths of Carlsson

A

-Meta analysis was used
-used PET scans
-leads to new drug treatments

89
Q

weaknesses of Carlsson

A

-used lots of animal studies
-secondary data

90
Q

what are the key features of a case study

A

quan and qual data
study of individuals or multiple individuals
triangulation

91
Q

A

a single session was carried out for 6 individuals with fragile ego boundaries and sz. they were called the Thursday group

97
Q
