Q

How does the HPA axis work in non depressed individuals?

A

When rising cortisol levels are detected by GR (glucocorticoid receptor) in the hippocampus, the hippocampus stops production of CRH.
(the negative feedback loops suppresses the HPA axis)

Q

How does the HPA axis work in a depressed individual?

A

1) Severe temper outbursts at least 3 times/ week
2) Sad, irritable or angry mood daily
3) Reaction does not equal situation
4) Present in multiple settings

40
Q

41
Q

What is the diagnostic criteria for Bipolar I disorder (BPI) aka manic-depression?

2) Symptoms last at least 1 weeks
3) Marked impairment in functioning

42
Q

Are MDEs necessary for a BPI diagnosis?

A

NO (despite the term bipolar)

Q

In general terms what is a manic episode?

A

Abnormally elevated mood or irritability PLUS increased energy

44
Q

What additional symptoms are required for a manic episode?

DIG FAST
45

A

YES

47
Q

How long does mania usually last?

A

about 3 months

and occurs directly before/after an MDE

48

A

YES

Based on studies showing MZ co-twin with BPI about 80%

49
Q

Is BPI more genetically controlled than MDD?

A

YES

50
Q

Manic episodes involve increased activity of what?

A

Monoaminergic activity

51
Q

What are the three main drugs used to treat manic episodes in individuals with BPI?

A

1) Lithium
2) Anticonvulsants
3) Antipsychotics

52
Q

What are the two main drugs used to treat MDEs in individuals with BPI?

A

1) Antidepressants (ADs)–> need mood stabilizer if used

2) Antipsychotics —> different then the mania antipsychotics used

53
Q

What are the use of Antidepressants (ADs) contraindicated in treatment of MDEs in BPI patients?

A

risk of inducing mania

54
Q

What is the only FDA approved drug for BP depression?

A

Antipsychotics

55
Q

ECT treatment is also used in BPI patients, does this treatment treat the manic or depressed states?

A

BOTH

56
Q

Is psychotherapy used for BPI patients?

A

Yes but not to treat primary symptoms

57
Q

What is the diagnostic criteria for BPII patients?

A

Person experiences at least 1 MDE and at least 1 hypomanic episode

58
Q

Hypomania includes the same symptoms of mania, so how are they different?

A

Severity
Mania= marked impairment in functioning
Hypomania= does not (therefore does not significantly affect patients life)

59
Q

How long does a hypomania episode need to last for BPII?

A

At least 4 days

60
Q

In BPI the disruptive problem is the manic episodes however in BPII the patient only experiences hypomanic episodes so therefore what is the main disruptive problem in BPII?

A

Depressed phase

61
Q

How do you treat BPII?

A

Same as BPI with a focus on bipolar depressed drugs

62
Q

What is the diagnostic criteria for cyclothymic disorder?

A

1) >2 years a person experiences periods of hypomanic symptoms that fluctuate with periods of depressive symptoms
2) Criteria for MDE has not been met

Q

How is cyclothymic disorder and BPI different?

A

Mood shifts are not as extreme

64
Q

What is the treatment for cyclothymic disorder?

A

Mood Stabilizers

In BP disorders is an MDE or manic/hypomanic episode the first mood episode?

A

could be either

66
Q

What are some factors suggesting a bipolar depression?
