Q

Defining mental disorders: Infrequency

A
  1. Something is a mental disorder because the symptoms the person experiences are statistically infrequent (e.g. auditory and visual hallucinations)
  2. Doesn’t hold: While some mental disorders are statistically infrequent (schizophrenia), there are other conditions that are frequent (depression); 48% lifetime prevalence rate for having any DSM-5 mental disorder

Q

Defining mental disorders: Deviance

A
  1. Mental disorder as atypical behaviour for a particular context (normative/contextual deviance)
  2. Opponent of deviance definition: Thomas Szasz wrote a book arguing that society has defined what a mental disorder is without any real biological underpinnings (mental illness/mental health issues are a social construct)

Q

Defining mental disorders: Distress

A
  1. Mental disorder defined by subjective distress
  2. Issues: Not applicable to all mental disorders, as it depends on individual’s degree of insight/self-awareness - mental disorders not always accompanied by distress (e.g. NPD)

A
  1. Diagnostic and Statistical Manual of Mental Disorders (published by the APA in 1952)
  2. DSM-3 (1980): Push for it to be more descriptive and less theoretical (have a symptom checklist, certain number where you meet diagnostic criteria)

Biomedical/biological treatment

A
  1. Consider mental illness a biological disease (disease of the brain and central nervous system)
  2. Medication can be used to remove or at least improve symptoms of disorder, brain surgery may be used but is highly unusual

Q

Psychological treatment: Psychodynamic (a.k.a psychoanalytic) approaches

A
  1. Developed by Freud, tried to define what was “normal” and had no interest in defining what was problematic and how to intervene
  2. Strong emphasis on child development (sees psychological difficulties as stemming from unresolved childhood trauma/difficulties)
  3. Sees behaviour as driven by powerful unconscious inner forces
  4. Insight-oriented approach - goal of psychoanalysis is for patients to arrive at an insight for why they are having certain difficulties

Q

Psychological treatment: Behavioural approaches

A
  1. Second oldest modality, largely a rejection of psychodynamic theory
  2. Focus on the present, rooted in principles of classical and operant conditioning
  3. Goal is to: Use techniques that counter essentially-conditioned punishments (e.g. phobia of dogs treated with exposure therapy), extinguish non-productive/upsetting behaviours, reinforce desirable behaviours

Exposure therapy

A
  1. Works on the principle of habituation - the more a person is exposed to fear-provoking stimulus, the more accustomed they get to being around it
  2. Systematic desensitisation: imagine the stimulus (imaginal exposure) –> focus on relaxation techniques –> eventually be directly exposed to stimulus (in vivo exposure)
  3. Effective in 70-90% of cases

Q

Aetiology of depressive disorders: Biochemical (biological factor)

A
  1. NTs: Low levels of norepinephrine (increases energy), serotonin (mood regulation), and dopamine (processing rewards in environment) linked to depression
  2. Hormones: Cortisol released through the Hypothalamic-Pituitary-Adrenal (HPA) axis in response to stress, chronically excessive cortisol linked to breaking down NTs such as serotonin

Q

Aetiology of depressive disorders: Brain abnormalities (biological factors)

A
  1. Limbic system (composed of amygdala and hippocampus) sends signals through our serotonergic pathways to prefrontal cortex (where info comes to our awareness) –> less serotonin in body disrupts this
  2. Prefrontal cortex doesn’t function very well for individuals with MDE (can’t inhibit maladaptive emotional responses that well)
  3. Left-frontal hemisphere asymmetry linked to depression (left frontal lobe associated with more positive emotions)

Q

Psychological theories of depression: Cognitive theories

A
  1. One of the founders of cognitive theories of depression and cognitive therapy was Aaron Beck
  2. Way we perceive environment is what contributes to depression, as well as other mental disorders (hopelessness + rumination [thinking about negative events in one’s life] –> depression)
  3. Negative triad: negative thoughts about self, others, and the future –> depression
  4. Cognitive distortions: should-ing, over-generalisation, discounting positives, black-and-white thinking, unfair comparisons
  5. Integrative model of depression: biological + psychological vulnerability –> activation of stress hormones which affect NTs, maladaptive cognition, social issues —> mood disorder

Q

Aetiology of schizophrenia (one of the most heritable mental conditions): Genetics

A
  1. Study by Sullivan found that about 80% of the symptom variation associated with schizophrenia can be attributed to genetic effects, can be 95% confident that that number is between 70-90%
  2. Study from Denmark (roughly same population size as NZ) compared identical and fraternal twins with respect to concordance rate of schizophrenia, calculated that it was approximately 73% (Hilker et al., 2018)

Q

Dopamine paradox in schizophrenia

A
  1. Excessive dopamine in the subcortical areas (limbic system) → positive psychotic symptoms
  2. Reduced dopamine in prefrontal cortex → negative psychotic symptoms
  3. Research suggests that this really involves different dopaminergic pathways - in prefrontal cortex, less dopamine; limbic system has more dopamine (more of an imbalance)
  4. Implications for a learning paradox (Millard et al., 2022): individuals with schizophrenia tend to condition rewards in the wrong things
81
Q

Biological treatment for schizophrenia

A
  1. 1st gen antipsychotics: Reduced positive symptoms, but had side effects (tardive dyskinesia [TD], neuroleptic malignant syndrome [NMS])
  2. 2nd gen antipsychotics (hoped to reduce side-effects), target both positive and negative symptoms of psychosis
82
Q

Cognitive treatment for schizophrenia: Cognitive rehabilitation

Q

“Psychopathy” data

A

15-25% of prison population meet psychopathy requirements, as compared to 1% of general population

182
Q

Psychopathy symptoms (in addition to ASPD):

A
  1. Interpersonal deficits: Superficial charm, grandiosity, pathological lying
  2. Affective deficits: Shallow emotions, fearlessness, callous, lack of empathy, guilt, and remorse, inability to form deep relationships
183
Q

Two-process model for aetiology of psychopathy

A
  1. Affective/interpersonal: People with psychopathy have lower volume, reduced functioning in their amygdala – poor fear conditioning, inability to read distress cues
  2. Antisocial behaviour: Orbitofrontal cortex – disinhibition, poor emotional decision making
184
Q

BPD (border between neurosis and psychosis)

A
  1. Instability of self-image and relationships: Identity disturbance, intense interpersonal attachments, idolization vs. evaluation
  2. Affective instability: Dysphoria and chronic feelings of emptiness, prolonged/violent emotional outbursts, extreme emotional response to abandonment
  3. Impulsive, unpredictable, and destructive behaviour:
    Bouts of anger/violence, suicidal gestures, substance abuse, reckless behaviour
185
Q

Aetiology of BPD: Biopsychosocial theory (M. Linehan)

A

Genetic vulnerability to emotional dysregulation coupled with invalidating childhood environments (not learning from the environment to appropriately regulate their own emotions)

186
Q

Aetiology of BPD: Psychological

A

Psychodynamic → early parent relationships
1. Object-relations → lack of early acceptance by parents (attachment disturbance to other people; can’t form attachments to people in a safe manner)

187
Q

Treatment of BPD

A
  1. Dialectical behaviour therapy (DBT; initially designed to deal with extreme behaviours such as suicidality); DBT therapists on call for patients at all times
  2. Mentalization-Based Therapy (MBT): Psychodynamic, helping individuals develop an appropriate perspective
188
Q

Prevalence of BPD: Volkert et al. (2018) meta-analysis

A

Prevalence rate for at least one PD was 12.16%

189
Q

Ten-Year Course of BPD: Gunderson et al. (2010)

A

Found that if you studied individuals with BPD over time, they often remit - not as stable of a disorder as once thought

190
Q

Limitations within DSM-5 system for PD diagnoses:

A
  1. Excessive comorbidity (if you meet diagnostic threshold for at least one of these PDs, there’s at least 50% chance you’ll meet diagnostic threshold for another PD)
  2. Inadequate coverage - 40% of patients who meet general PD threshold don’t map onto any of these 10 PDs
  3. Excessive within-diagnosis heterogeneity - lots of different presentations in the same PD
  4. No clear boundary between normal and pathological personality
  5. Inadequate scientific base
  6. Marked temporal instability
191
Q

DSM-5 Section III Alternative Model (not adopted, placed in appendix): PDs

A
  1. Criterion A: Significant impairments in self (identity or self-direction) and interpersonal (empathy or intimacy) functioning
  2. Criterion B: Personality profile (five personality traits domains with three to seven facets each)
    Negative
    Affectivity
    Detachment
    Antagonism
    Disinhibition and compulsivity
    Psychoticism
  3. Six PDs, not 10
192
Q

DSM-5 Section III Alternative Model PDs:

A
  1. Antisocial
  2. Avoidant
  3. Borderline
  4. Narcissistic
  5. Obsessive-compulsive
  6. Schizotypal
193
Q

ICD-11 and PDs

A
  1. Published in 2018
  2. Approved for full acceptance by WHO member states in 2019, formal implementation by member states in January 2022
  3. PDs changed from categorical to dimensional
    (PD is a dimensional impairment continuum - personality traits can be used to characterise manifestation of PD)
194
Q

6D10 - PD (from ICD-11)

A

Severity gradient (how prevalent symptoms are across contexts, how are they impairing the individual), with different diagnoses for that severity

195
Q

6D10 PDs: Personality difficulty (no disorder/no real diagnosis)

A

Some disturbance in self-regulation or interpersonal functioning, but does not cause considerable subjective distress or impairment in functioning

196
Q

6D10 PDs: Mild PD

A

Disturbances affect some areas of personality functioning but not others, typically no harm to self or others, distress/impairment could be more circumscribed contexts or mild if in many

197
Q

6D10 PDs: Moderate PD

A

Disturbances affect some areas of personality functioning but not others, harm to self or others could be present, distress/impairment is marked across contexts, although functioning in some circumscribed contexts could be maintained

198
Q

6D10 PDs: Severe PD

A

Severe disturbance across contexts, functioning severely compromised, virtually all relationships and contexts are affected, often associated with self- and/or other harm, severe impairment in all or nearly all areas of life

199
Q

6D10 PDs: Trait qualifiers

A

Five personality trait qualifiers:
1. Negative affectivity (dispositional proclivity towards experiencing a wide range of negative emotions, emotional dysregulation, interpersonal difficulty/anxiety)
2. Detachment (extreme social withdrawal)
3. Dissociality (analogous to antagonism, disregard for others, self-focused, grandiose, etc.)
4. Disinhibition (impulsivity, risk-taking)
5. Anankastia (compulsivity, perfectionism)
6. Borderline pattern (initially not included) - personality disturbance characterised by a pervasive pattern of instability of interpersonal relationships, self-image, emotions, and marked impulsivity (as indicated by the nine symptoms of the traditional BPD diagnosis)
