Q

Stress response (depression)

A
  • HPA releases cortisol in response to chronic stress, ANS responsible for fight/flight/freeze
  • Hippocampus responsible for HPA regulation
  • 80% those hospitalised for depression show poor HPA regulation (Heusch)
  • Cortisol: enlargement of adrenal glands reducing frequency of serotonin receptors

Q

Psychoanalytic theory (Freud 17) for depression

A
  • Depression response to loss
    Introjection:
    1. Loss in adulthood - regress to oral stage
    2. Integrate lost object with own identity
    3. Direct feelings to lost object at self
    4. Leads to self hatred and low mood

Unmet needs during oral stage = vulnerable to develop depression

Q

Evidence of psychoanalytic theory: Kim et al, Goodman, Harris et al (depression)

A

Kim et al: self directed anger is strongly associated with depression
Goodman: unmet needs as a child = more likely to become depressed after experiencing a loss
Harris et al: women whose mothers died/abandoned them more likely to develop depress

Q

BPD: Genetics - Torgeson et al 00, Smith et al 04

A
  • Does appear to run in families, 35% MZ, 7% DZ (T)
  • 44% comorbid with bipolar disorder - could account for unpredictable mood swings (Smith et al 04)
  • Short allele variant of 5-HTTLPR polymorphism (regulates expression of serotonin transporter gene) - risk factor but common to many

Q

Neurobiology - BPD, Lis et al (07)

A
  • Limbic system (emotion and learning)
  • Amygdala (threat perception and coordinates and initiates fear response)
  • Hippocampus - involved in spatial learning and contextualising memory
  • Lis et al (07) noted excessive activation of limbic system and amygdala
  • But could be c/e, cmbd/substance misuse
17
Q

BPD: NTS

A
  • Dopamine (mood, reward, motivation)
  • Serotonin (mood and impulsivity)
  • GABA (anxiety)

In BPD, low levels of serotonin (nora) and some evidence for dysfunction in DA but evidence circumstantial

18
Q

Biological treatments for BPD - Walker et al (03), Cailhol et al (14)

A
  • Generally used to treat comorbid e.g. a-d for depression and lithium chloride for bipolar
  • Walker et al (03): investigated quatiapine (atypical antipsychotic) in a case study of 4 participants suffering from severe ASPD, severest case seen. Effective in reducing anger, irritability and impulsivity - due to expenses prisons have discontinued it resulting in increased anger (only 4 patients and treatment short term)
  • Very few RCTs examined medication and those that have are poorly controlled, small sample size and equivocal
19
Q

BPD: biosocial theory - Lineman (87)

A
  • main theory currently used
  • innate vulnerability that compromises capacity for emotion regulation is chronically exposed to invalidating environments
  • Individual communicates about inner challenges but is consistently invalidated (mild-extreme) and so becomes more self invalidating
  • Mod. displays of emotion regul punished
  • Severe displays - fam. concerns for medic. care
  • Ind. may have on going emotional inhibition with periodic intense emotions
  • Thus biological disposition + invalidating environment - person has trouble regulating thoughts, feelings and behaviours and emotions experienced more intensely than average person
20
Q

BPD: Dialectical behaviour therapy

A
  • Dialectics: trying to balance
  • A1) accept who you are
  • A2) change - make positive changes in life, reduce suicidal behaviour, behaviour that interferes with therapy and also that reduces quality of life, engage in behavioural skills for emotion regulation and enhance self respect
    A3) aware of maladaptive behaviours and consequences of them

4 stages: distress tolerance/interpersonal functioning/ emotion regulation/mindfulness

Multimodal programme

21
Q

BPD: DBT support

A
  • Effective therapy for BPD
  • McMain et al (12): long lasting positive effects on suicidal and non suicidal self harm behaviours, depression, interpersonal functioning, anger control and re-hospitalisation

Soler et al 05: effective when combined with app. medication

Stoffer et al 12: cochraine review of BPD: DBT decreases inappropriate anger, self harm and improves general functioning

22
Q

BPD: object relations theory

A
  1. children learn about others through relationships with mothers/caregivers
  2. Initially child does not distinguish between representations of self and mother and views things as either all good or all bad
  3. During development, child realises they are separate from mother and begins to integrate all good/all bad object relations

Thus, neglectful/abusing/loveless/inappropriate parental behaviour - child fails to develop mature object relations - personality fails to develop correctly

  • Develops insecure ego, low self esteem and fears separation and rejection (Bartholomew et al)
  • Use defines mechanism - Splitting! evaluates people in black and white, difficulties in relationships when people don’t meet high standards
23
Q

BPD: evidence for object relations theory

A
  • Suvak et al: individuals with BPD judge things on valence, no intensity control
24
Q

BPD: Object relations psychotherapy

A
  • insight is mechanism to change
    1) show client how normal ways of behaving defensive
    2) normal ways of thinking too simplistic causing swing between +/- emotions
    3) provide more adaptive ways of dealing with important life issues
  • Therapist active role
    1) clarification: asks p to elaborate on thoughts/emo on self/other in problemat. situ.
    2) confrontation: point out inconsistencies between differing accounts of self/other
    3) interpretation: offer explanation for inconsistencies by suggesting links between defence mechanisms and anxiety associated with trying to link all good/bad OR

Outcome:

1) capacity to reflect on own and other’s roles in emotionally intense interaction increases
2) better able to tolerate painful emotions without resorting to all good/all bad thinking and stop them from acting out emotions in destructive ways
3) series of trials supporting effectiveness in functioning for BPD (Yeoman’s and diamond 10)

25
Q

Clarkin et al - BPD

A
  • DBT, TFT and supportive counselling
  • 90 ps
  • All demonstrated improvements in depression, anxiety, global functioning
  • TFT and DBT: improvements in suicidality
    TFT and supportive counselling: improvements in agression
26
Q

CBTheory: BPD - Aartz

A
  • Assumes childhood abuse results in dichotomous thinking in that people/situations = all good/all bad
  • Abuse contributes to development of dysfunctional schemas in that self is vulnerable, bad, helpless and others = malevolent and abusing
  • Develop multiple coping strategies - simulatensouly becoming clingy as they need help but then distancing due to fear of rejection - constantly flicking between the 2 causing them to become hypervigilent s they expect both abuse and abandonment
27
Q

BPD: Padesky, CBTherapy

A

1) work axis 1 problem and improve overall functioning & teach mood management and behaviour change strategies
2) conceptualise old and construct/strengthen new personality system
3) prepare for termination and relapse prevention

28
Q

BPD: Davidson et al (04)

A
  • BOSCOT Trial
  • CBT + TAU vs TAU
  • 102ps, 2 year follow up, real clinical setting (high efficacy)
  • 27 CBT sessions over 12 months, 16 on av
  • Gradual and sustained improvement in both interventions
  • Reduced suicidal behaviour, increased attendance at A&E and in patient psychiatric open days
  • 1 year: improved distress
    2 year: improved anxiety, dysfunctional beliefs and suicidal acts
29
Q

BPD: McMain et al

A
  • CBT and TAU vs TAU
  • Both showed similar statistical significance after 2 years
  • 3 years - consistent finding - 53% unemployed, 39% receiving disability support - illustrating occupational/educational impairment in daily life - needs addressing
