25
neurology study of conversion disorder
poked patients in unaffected leg - reaction in brain. poked in affected leg = no reaction. poked both together and lots of reaction suggesting it is a false physical problem
26
freud and anna o
she was paralysed on onse side, found to be a mental health problem, using the repression defence mechanism
27
neurology of conversion
in the left hemisphere theres a supression of memories dorsolateral frontal cortex and activity in the hippocampus
28
epilipsey and conversion
theres an increased acitvty in the temporoperietal junction which is associated with epilesipy and out of body experiences suggesting they leave their body
29
treatment for conversion
psychoanalysis talking therapy for 12 weeks to being repressed belief to the surface
30
factitious disorder
falsification of symptoms treatment = talking therapies

Munchausen by proxy disorder
child abuse, giving child/ believing they have physical symptoms that are not there

18% had secure attchment to parent, unresolved loss/fear of less, 60% had abuse aswell
33

help seekers doctor addicts inducers
34
treatment of munchausen by proxy
firslty classify which one they are, talkig therapies, not much research .
35

positive, what you gain, hallucintaions, dillusions, caused by too much dopamine, reversible
36
what is type two schizophrenia?
negative, what you lose, speech, organisation skills, not reversible
37
neurology of schizpohrenia
- enlarged ventricle mass - temporal horn englarged - more on left side than right - because these are englarged it changes the organisation and other grey matter mass in the brain
38
there is less of what brain tissue in people with schizophrenia
superior temporal gyrus brain tissue
39
what cells are different in shizophrenic patients
pre alpha cells
40
treatment for schizophrenia
dopamine blockers
41
causes of schizophrenia
- brain matter loss - thumb ridge count - 2nd trimester of pregnancy
42
what is the fantasy model?
dissacociation propensity --> mediators (fantasy proneness) --> trauma memories created
43
what is the trauma model?
sociocognitive model trauma --> mediators (genetics, environment) --> dissociative tendencies
44
avoidance behaviour in DID?
means of depersonalisation and avoiding reminders of trauma. It then increases in frequency  because it works , turning to the alter personalities
45
neurological differences in DID sufferers#?
enhanced activity in the amygdala, frontal cortical regions increased blood flow in medial and superior fontal regions parietal and prefonrtal lobes
46
what are the frontal cortical regions associated with?
dysregulation of consciousness
47
pattern recognition in DID
using a brain pattern recognition software they were able to accuratley identify 74% of people with DID this is similar level to that of other mental health disorders.
48
treatment stages for DID?
1, creating feelings of sefety between patient and client 2, CBT 3, trauma based work 4-5, increasing daily skills of the host

51
facebook addiction study
more facebook usage = more brain response to likes
52
what is thetre less of in additcs
less dopamine receptors
53
gaming gray matter
less gray matter in brain areas the more you game
54
explain the mesolimbic dopamine system
dopamine system that is affected by the use of drugs dopamine projection to the ventral tegmental area (main dopamine producing area in the brain) --> mesoaccumbens - nucleus accumbens (pleasure) / --> medial prefrontal cortex
55
electrical brain stimulation
rats shocked pull lever kept going back to have more - addiction
56
grey matter in cocaine addicts
reduced gray matter in the frontal love in people who do cocaine
57
neurology of trichotillomania
increased cortical thickness found in MRI scan in the superior temporal gyrus, region associated with self-awareness.
58
what disorder is related to the behaviours of people with trichotillomania
OCD the hair pulling, in some people, equates to the compulsive behaviour that offers temporary relief from anxiety in OCD sufferers
59
treatment for Trichotillomania

awarness training --> what trigers hair pulling etc competing response training ( a behaviour that ohysically stops hair pulling) social support --> positive feedback for not taking part in hair pulling
61
