Social problems and psychiatric ones

Rates, worldwide and Canadian

Trends in Canada

34

Reasons:1. Disinhibitors: “social involvement and identity”

egoistic altruistic anomic

Affective DisordersSuicide

Summary:“Why people die by suicide”:

“Disconnectedness and Ineffectiveness”

Issues:1. Ambivalence

“to be” “not to be” “maybe”

2. Intervention passive suicide assisted suicide euthanasia

36

Affective Disorders

Issues:3. Prevention

societal solutions imitation and contagion (“The Werther Effect”) the biology of suicide

4. Prediction predicting rare events predicting in practice the predictors

• past attempts (the best predictor)• present plan (availability of lethal means)• person (social support)

Somatoform & Dissociative Disorders

38

Somatoform disorder

What is happening here?

1. Conversion (“hysteria”)

– Sensory and motor symptoms– Over and under-diagnosis– Purpose?– Compare: “self serving bias” and “self-handicapping”– Notes: “La belle indefference” and lateralizatoin – Conversion, selective attention and dissociation

39

Somatoform disorder

2. Somatization

– Diagnosis– Theory– Therapy– Chronic Conversion?

40

Somatoform disorder

3. Hypochondriasis (and “cyberchondria”)

– Medical preoccupations– Other needs (and “medical offset”)?

“a disorder of cognition and perception”

41

Somatoform disorder

4. Somatoform pain

– Painful preoccupations– Primary and secondary gains?

5. Body Dysmorphia

– Physical preoccupations– Some possibilities (and “muscle dysmorphia”)?

Group forms, old and new

42

Somatoform disorder

MalingeringMalingering: deceit with a purpose

Factitious disorderFactitious disorder:

Munchausen syndrome

Note: self-induced and “proxy” forms

How do you know?

What do you do?

43

Dissociative disorder

What is happening here?

Hypnosis and the study of “dual consciousness”

“Pre-attentive Processing”1. “Dry”: the research in the lab

... the how of “implicit perception and memory”

2. “Wet”: the experience of everyday life

... the why of “intentional not-thinking”

44

Dissociative disorder

AutobiographiesAutobiographies: “deep” and “superficial” memories

... the facts, feelings and fictions

Demonstrations of dissociationDemonstrations of dissociation: group & personal ones

... the Dissociative Experience Scale

45

Dissociative disorder

1. Dissociative Amnesia Motivated lack of awareness Recovered Memories

1. “Dry”: the learning theory view of memory

... how learning and memory serve external, adaptive needs

2. “Wet”: the psychodynamic view of memory . .. how learning and memory serve internal, personal needs

The lesson from life:The lesson from life: “the complexity of awareness about highly traumatic events”

46

Dissociative disorder

2. Dissociative Fugue

Motivated lack of awareness and movement Episodic, declarative and procedural memory

47

Dissociative disorder

3. Dissociative Identity Disorder

Over and under-diagnosis:“Multiple Personality Disorder” and its problems

Post-traumatic Theory (and “asymmetrical amnesia”)

Sociocognitive view (and “iatrogenic illness”)

Notes: suggestibility and dissociation-proneness

48

Dissociative disorder

4. Depersonalization Disorder

Derealization:“where am I?” and “out-of-body” experiences

Depersonalization:“who am I?” and “partial dissociation”

Note: The story of “Possession/trance disorder”

History

Moral insanity, psychopathy and “The Mask of Sanity”

The DSM:

from “Sociopathic Personality Disorder”

to “Antisocial Personality Disorder”

- the problem in principle: no symptoms

- the problem in practice: no reliability

72

History

The Modern Criteria and prevalence rates

The new problem: criteria “too broad and too narrow”

The Psychopathy Checklist

“Successful Psychopaths”

73

Research

A. Biology, then and now

Concordances: monozygous and dizygous

Adoption: retrospective and prospective

Cross-fostering observations

Other longitudinal research:

“Deviant children grown up” : predictors (Robins)

Prognosis in adulthood

74

Research

B. Psychological factors, then and now

Parents and their children:

Attachment Theory and the “affectionless psychopath” (Bowlby)

Adaptation to Life and “sociopathy” (Vaillant)

“Failed encounters” and the “fledgling psychopath” (Moffit et al)

Cross-cultural studies

Gene-environment interactions:MAO-A and maltreatment

75

Theory

1. The (“primary”) Psychopath... and biological precursors

2. The Sociopath (or “secondary psychopath”)... and psychosocial precursors

e.g Two types of children (Frick)

The difference it makes remission prognosis treatment

76

Theory

The nature of psychopathy

The context: “a mixed incentive task”

A B C D

Passive avoidance conditioning and the “low fear” model (Lykken)

wrong WRONG! RIGHT wrong

77

Theory

The Theory: “an inhibitory deficiency”BAS (Behavioral Activation System)

BIS (Behavioral Inhibition System)

The Theory, updated:Emotional and cognitive components

“dual deficit” model “attention” model

78

Theory

means and motives

... comorbidities and their implications

79
