They are proteins that are released when there’s an infection, fatigue and activation of HPA axis.

Pro-inflammatory cytokines have been implicated in depression and schizophrenia

43

A

Antidepressants (Prozac): inhibiting reuptake of serotonin

Benzodiazepines: stimulates GABA neurons to inhibit systems responsible for physical symptoms of anxiety

44
Q

What does it mean we have to be cautious of reductionism?

It attempts to influence thoughts, perceptions, self-statements and unconscious assumptions in order to modify overt and covert disturbed behavior

53
Q

What is cognitive restructuring?

A

Changing pattern of thought

54
Q

What therapy did Aaron Beck develop and what was his idea behind it?

55
Q

For which 3 disorders are negative cognitive tendencies a good predictor?

A

Depressive disorders, anxiety disorders and PTSD

56
Q

What are 2 things you need to consider when linking emotional disturbances with psychopathology?

A
  1. Consider which emotion components are affected
  2. Ideal affect: emotional states a person ideally wants to feel
57
Q

On what does ideal affect depend?

A

It depends on cultural factors (how someone ideally wants to feel)

58
Q

What are 4 sociocultural factors that influence different psychological disorders?

A
  1. Gender: disorders have different effect on men and women
  2. Poverty: related to antisocial disorder and anxiety
  3. Cultural/ethnic factors: some mental disorders can be observed in different cultures but their conceptualization varies. Other disorders are specific to cultures (eating disorders)
  4. Race: schizophrenia is more prevalent among blacks compared to whites
59
Q

What are examples of interpersonal factors and how are they related to disorders?

A

The quality of family, relationships, social support and the amount of casual social contact

They influence the course of disorders

60
Q

What is interpersonal therapy (IPT)?

A

It encourages the patient to identify feelings about his/her relationships and to express these feelings and then help the patient generate solutions to interpersonal problems

61
Q

What 4 interpersonal issues are assessed in interpersonal therapy (IPT)?

A
  1. Unresolved grief: deleayed grieving following a loss
  2. Role transitions: transitioning from child to parent e.g.

A

Subjective experience of distress in response to perceived environmental problems

63
Q

Why can’t you establish a causal relationship in the study of the effects of environment en socioemotional influences?

A

You can’t experimentally study it. That is ethically not okay

64
Q

What are 2 obstacles in the study of the effects of environment and socioemotional influences?

A

68
Q

What is the diathesis stress model? Describe how it looks

A

Heritable predisposition + early experiences
–> influences strengths and vulnerabilities

Strength/vulnerabilities (diathesis) + stress –> influences complaints/symptoms

Complaints/symptoms have feedback loop to diathesis and stress, which then loops back to symptoms again

Heritable: genotype, temperament

Early exp.: nurture, care, trauma, deprivation

Fenotype, schemas, cognitions, attributions, attachment style, personality, neuro endocrine etc.

71
Q

Give examples of support and stress in the diathesis stress model

A

Social environment, medication, psychotherapy, daily stress, trauma, life events etc.

  2. Best external evidence
  3. Patient values & expectations
74
Q

Who was a pioneer in client-centered therapy? How does it work?

A
  1. Authenticity
  2. Unconditional positive regard
  3. Empathy
76

Not very well supported though

77
Q

How did Albert Ellis pioneer early cognitive therapy?

A

Ellis challenges one’s cognition very actively by talking a lot and telling client what she has to think

This sometimes works for people who never really had support. It sometimes gives you guts to try new behavior

78
Q

What is gestalt therapy according to Perls? Why can it be harmful?

A

It’s process oriented and focuses on experiencing the here and now.

It uses techniques such as the empty chair technique.

It’s sometimes effective and sometimes harmful. Harmful because a strong emotional event memory is formed
