Q

How can you assess mood disorders?

A
  • Unstructured clinical interviews
  • Semi-structured diagnostic interviews (e.g., Structured -
    Clinical Interview for DSM)
  • Clinician rating scales (e.g., Hamilton Rating Scale for Depression)
  • Self-report questionnaires (e.g., Beck Depression Inventory)
  • track severity
  • All of these methods are useful to get information

Q

How do you assess mood disorders in children?

A

Child self-report, parent-report, teacher-report
Only modest correlations (~ .30)

  • children are not good reporters of their symptoms
  • adolescents may not want to reveal some of the problems they are dealing with

Q

Are the prevalences of disorders in the US and over or under estimate?

A
  • Some people think that it is high and most people don’t have clinical symptoms or that maybe depression is too high
  • Some people think that it is too low because people might not report accurately, or don’t report periods of low moods, maybe some people don’t get treatment, or don’t think about it
  • Some rates are higher, especially for MDD, a common disorder that affects a lot of people
  • We should think about how we currently define disorders

Q

How are rates of depression affected by age and sex in the national comorbidity study?

A
  • First national comorbidity study. Rates of depression increase in adolescence, when sex differences also emerge and persist throughout adulthood. Similar findings in all epidemiological studies.
  • We see that at the beginning the rates of depression are similar for men and women
  • Sex differences begin to emerge during adolescence around puberty
  • A lot of things are changing around the time of puberty

Females who go through puberty higher than their peers may be more susceptible to depression
IF you go through puberty earlier you may hang out with older kids and may do things you aren’t prepared for like intimate relationships

Q

Where did depression rank in 2017 in the WHO Global Burden of Disease study?

A

In 2017, depression ranked 3rd for females and 5th for males worldwide in years lived with disability (WHO Global Burden of Disease study)

  • Depression ranks remarkable high, top 5 for all mental disorders, ranks higher than many severe physical disorders
  • Can be because of how people process their emotions and what they think of depression

Q

What physical diseases is depression associated with?

A

cardiovascular, type 2 diabetes, autoimmune diseases

  • Depression causes a lot of stress and can lead to some of those diseases, but also having those diseases can lead to a lot of stress that causes depression
  • Shared risk factors such an environmental factors
  • Genes that are involved in depression can also be similar genes for physical diseases

Q

Why do you have to pay attention to course and complications of treatment?

A

Prognosis, treatment planning, evaluating treatment, theory and clues for etiology

  • Important to evaluate the effects of treatment
  • Gives you expectations when trying new treatment
    Some patients do get better without treatment
  • Useful for theory about etiology of a disorder
  • Depression and BPD are often episodic
  • Not particularly evidence based these terminology

Q

What does remission mean in terms of course and complications?

A

Remission – does not meet dx criteria for > 3 wks
Can be partial or full

you have a response can no longer meet criteria for the disorder for at least 3 weeks,

  • can be full – no more symptoms,
  • partial – you can no longer meet the criteria but you still have some lingering symptoms,
  • partial remission is one of the best predictors for relapse or recurrence, target for treatment should be full remission

A

Men 3x more likely to complete; women 2-3x more likely to attempt
Sex differences in lethality of means

40
Q

What are some risk factors for suicide?

A
  • Older males; whites; not married; sexual minorities; groups undergoing social disruption
  • Previous suicide attempts (33%)
  • 90% of suicides have a psychiatric disorder: depression (2-6% suicide rate; somewhat higher in bipolar disorder); schizophrenia; anorexia; substance disorders
  • Hopelessness
  • Impulsivity
  • Social isolation; interpersonal loss
  • Physical illness; financial loss; legal problems
  • History of early adversity/maltreatment
  • Family history of suicide (genes appear to play a role)
  • Some evidence for contagion via peers and media
41
Q

Is suicide a rare phenomenon in the general population?

A
  • Yes
42
Q

What are some protective factors for suicide?

A

responsible for children; religiosity

  • Having the thought of what happens to my children might stop someone from committing suicide
43
Q

When is the risk highest for suicide?

A

Risk is highest in the period after recovery from depression or hospital discharge

  • Risk for suicide continues even after someone recovers from depression, not clear how long the time is
  • When people are very depressed they don’t have a lot of energy to follow through with committing suicide but when they recover they may have more energy to go through with it
  • You shouldn’t stop worrying about someone even if they are feeling better
44
Q

Do people who are thinking of suicide communicate intent?

A

Yes in the majority of cases

  • They communicate some form of intentions or clues, may give away possessions
45
Q

Are we able to predict suicide?

A

challenges of predicting rare events (low base rates) and predicting transient states

  • Really bad at predicting if someone will commit suicide, even among people with a lot of risk factors because it is very rare
  • Over predicts suicide
  • We may be better if someone will EVER commit suicide, but that’s not what we want to know
46
Q

What is Thomas Joiner’s Interpersonal Theory of Suicide?

A
  • Acquired capability (habituation to pain, death through prior exposure)
  • Thwarted belongingness (i.e., social isolation or exclusion)
  • Perceived burdensomeness

Says that suicide requires 3 different elements and all need to be present

  • You acquire it over time, you get used to the pain or death maybe from past attempts or something else in your
    environment. Anything that makes it seem less extreme,
  • Thwarted belongingness- you want to belong and have a community but you don’t for whatever reason, a sense of alienation
  • Feeling like you’re a burden to other people, you’re not contributing value
47
Q

What was believed before the late 1970s about depression in children?

A

it was believed that children were not capable of experiencing depressive disorders.

48
Q

What happened in the late 1970s pertaining to children with depression?

A

investigators started interviewing school-age children about depression and found that they met full diagnostic criteria for MDD

49
Q

Is there a continuity for child depression and adult depression?

A

Mixed findings.

  • Children who are depressed do have family members that have higher rates of depression but also have higher rates of others issues such as substance abuse – it does run in families but all kinds of things runs in this family – could be a response to all the other difficulties
  • Homotypic continuity – mixed. Some studies show that children who have depression are more likely to have depression when they are older, but other studies show that they are more likely to develop a bunch of other things such as anxiety, eating disorders- can be a response to adversity
  • Antidepressant treatment seems to be weaker for children than adults
50
Q

Can preschoolers meet the criteria for depression?

A

Preschoolers can also meet the criteria for depression, but the depression almost never lasts for 2 weeks

51
Q

What is the prevalence of depression in adolescents?

A

For adolescence this is the period where people have the first episode of depression

It becomes fairly prevalent

52
Q

Is there a continuity between adolescent depression and adult MDD?

A

Depressed adolescents have family history of depression, recurrency of depression and they tend to respond to antidepressant treatment better than children but not as good as adults

53
Q

What is important to know about the relationship between antidepressants and suicide?

A
  • Medication that treat depression might increase suicidal thoughts or ideations in children, adolescents, and young adulthood
  • Black box warning warning about suicidality risk on antidepressants for younger people
  • Antidepressants are not very effective in children – risk are higher and the benefits are low
54
Q

What is pediatric bipolar disorder?

A

Bipolar disorder for children

  • Historically believed to be extraordinarily rare before adolescence
55
Q

When was Pediatric Bipolar Disorder recognized?

A

It was recognized in the mid-late 1990s

56
Q

What is the clinical presentation for pediatric bipolar disorder?

A

Clinical presentation – irritable, not elated, mood; no distinct episodes - “ultraradian cycling”

  • The irritability can be very severe
  • For kids there are no distinct episodes, may be irritable all the time, or may have short and frequent episodes
57
Q

What is pediatric bipolar disorder comorbid with?

A
  • Comorbid with other behavioral disorders such as ADHD
  • There is some overlap with ADHD with mania – distractibility, hyper activity
  • Opposition defiance disorder is also very common with these children

Do these kids really have BPD?

58
Q

Is there a continuity between pediatric bipolar disorder with adult bipolar disorder?

A

Relatives could have BPD

59
Q

Why was pediatric bipolar disorder a major public health problem?

A

maybe those kids didn’t have BPD and were being over diagnosed

60
Q

Why was Disruptive Mood Dysregulation Disorder introduced to the DSM-5?

A

solution to epidemic of pediatric bipolar disorder so they would be less likely to give them medications typically used to BPD

61
Q

What is DMDD characterized by?

A
  • Severe temper outbursts (verbal or behavioral), on average, three or more times per week
  • Outbursts and tantrums have been ongoing for at least 12 months
  • Chronically irritable or angry mood most of the day, nearly every day
  • Typically diagnosed between the ages of 6 and 10.
62
Q

When is DMDD typically diagnosed by?

A

The ages of 6 and 10

63
Q

Is DMDD valid?

A
  • Don’t really care if its valid mostly introduced for public health purposes
  • Might have a very severe form of ADHD and something else
  • No effective treatments for DMDD
  • This diagnosis doesn’t solve the problem, they are still very irritable kids but it does take away the label of being bipola
64
Q

Is DMDD distinct from oppositional defiant disorder and ADHD?

A

Yes?

There are some overlap

  • If you meet the criteria for DMDD you can’t also have oppositional defiance disorder
65
Q

What is the vascular depression hypothesis?

A

a subgroup of elderly whose depression is due to cerebrovascular disease

66
Q

What is the onset of vascular depression?

A

65 years or later

67
Q

What are the characteristics of vascular depression?

A
  • Late onset (> 65 yrs)
  • White matter hyperintensities on MRI
  • History of hypertension
  • No family history of depression
  • Cognitive deficits on neuropsychological testing
  • Lethargy, loss of initiative, apathy
  • Poor response to antidepressant medication
  • Increased risk of dementia

Probably a secondary effect of neurological damage due to cardiovascular disease

68
Q

What studies are under the behavior genetics of mood disorders?

A

Family studies
Is familial aggregation due to genetic influences?

Twin studies

Adoption studies

69
Q

What is the main question in family studies?

A

do mood disorders run in families?

70
Q

What is the bottom-up design in family studies?

A

probands -> relatives

Bottom-up: group of children and you study their siblings or their parents. You start with probands and study their relatives

71
Q

What is the top-down design in family studies?

A

parents -> offspring

72
Q

What are two kinds of interview to get information in family studies?

A

Direct interview vs family history interview

Direct interview :you can go to the doctors office and they will ask if there are diseases in the family – you might not know everything of your family history

Family history interview: You can interview everyone in the family – usually first degree relatives, more accurate picture, you have a more accurate picture if something is genetic

73
Q

Are rates of bipolar disorder and MDD elevated in relatives of probands with bipolar disorder?

A

Yes.

Rates of both bipolar disorder and MDD are elevated in relatives of probands with bipolar disorder

74
Q

Are rates of MDD and bipolar disorder elevated in relatives of probands with MDD?

A

No.

Rates of MDD, but not bipolar disorder, are elevated in relatives of probands with MDD

75
Q

What is associated with higher rates of MDD in relatives?

A

Early-onset and recurrence are associated with higher rates of MDD in relatives

76
Q

What percent of proband who have bipolar 1 have relative with bipolar 1?

A

3%

77
Q

What percent of proband who have bipolar 1 have relative with bipolar 2?

81
Q

What percent of proband who have MDD have relative with MDD?

A

14%

82
Q

What percent of proband who have no Dx have relative with MDD?

A

6%

83
Q

What is the design for twin studies?

A
  • Identical (monozygotic) twins reared apart
  • Monozygotic vs dyzygotic twins
  • Fraternal twins are dizygotic – no more genetically related than other biological siblings, about 50% of their genes
  • Identical twins are 100% genetically identical
84
Q

How can you see if genes are playing a part of mood disorders based on twin studies?

A

IF genes are playing a role in a disorder than if one has a disorder the other should have a disorder, should show greater resemblance of that disorder

Best way of separating genes is separating the twins
You want to separate genes from the environment
Twins are raised in the same family at the same time – assumption that the environment is stable – often violated

85
Q

What is hertiability?

A

measure of how much variations can be accounted for by genetics

  • So if the environment is the same it has to be due to genetics and vice versa
  • Heritability depends on how much variation there is in genes and the environment
  • Intelligence is highly heritable
  • Heritability is not an absolute number, can change based on variation of genes and environment
86
Q

If an Mz twin has bipolar disorder what is the percentage of the other twin getting it too?

A

40%

87
Q

How heritable is bipolar disorder based on Maudsley Hospital Twin Study?

A

96%

  • Higher than MDD
88
Q

How heritable is MDD based on Maudsley Hospital Twin Study?

A

52%

89
Q

What is the design for adoption studies?

A
  • Biological/adoptive parent as proband
    (With adoption studies we start with the biological parents giving up their child for adoption – see if the children have the same disorder as their biological parents and then their adoptive parents)
  • Adoptee as proband
  • Cross-fostering
90
Q

Why is cross-fostering hard?

A

if you have a history of a psychological disorder it’s much harder to adopt a child

91
Q

What is the summary of the Minnesota Adoption Study?

A

If the mother has a history of depression the adoptive children are more likely to have depression

Shows that environment is important

92
Q

How is the swedish population registry seperated

A

Intact, adoptive, not-lived-with father, and stepfather

93
Q

What is the swedish population registry study used for?

A

Used national health care registries to determine which individuals had been treated for MDD

94
Q

What are the parent-child correlations between genes + rearing, genes alone and rearing alone?

A

genes + rearing r = .17; genes only r = .08; rearing-only r = .08

  • You need genes and the environment for a greater risk of depression, doesn’t go beyond doubling the risk
  • For BPD the genetic effects are higher and the environment effects are lower
