Q

the importance of Emil Kraepelin’s findings regarding onset and mixed states

A
  • in his observations of over 900 patients with manic depression in 1917, he reported that the illness most frequently set on between 1 and 20 of age
    Also reported that the onset prior to 10 years of age was rare and mild, if it occurred at all.
  • children lack the higher cognitive structures required for a diagnosis of bipolar disorder
  • nearly 60% of bipolar adults recall having symptoms prior to age 19 and up to 20% prior to age 10
  • mixed states appear to happen more commonly in children and adolescents with bipolar disorder than adults. Mixed emotional presentations with more common in children than adults even in the absence of psychopathology of that elevated and mixed emotions alone are not diagnostic.

Q

DSM-5 diagnostic criterion A

A

Distinct period of elevated, expansive or irritable mood less than or equal to 1 week ( or any duration if hospitalization required)

  • marked impairments ( eg functioning, hospitalization or psychosis)
  • 3 of 7 symptoms if euphoric mood, 4 of 7 symptoms of irritable mood only
  • at least 1 week in duration = BP I
  • at least 4 days = hypomania (BP ii)
  • Psychosis or hospitalization= BP I

3 or 4 if irritable mood only:

  • decreased need for sleep

  • pressured speech ( more talkative than usual)
  • grandiosity or inflated self-esteem

Q

Mood Cycles

A
  • Dysthymia- chronic, low grade depression which can be as severely disruptive for a child as MDD
  • Mixed episodes- mania and depression at the same time
  • normal mood -> drops to depressions -> rises to mania -> drops a little -> rises to hypomania -> mixed episode ( up and down)
  • GRAPH*

Q

Pediatric Bipolar Disorder diagnostic dilemmas

A
  • the centrality of irritability
    • recommending a diagnosis of BP if the child meets DSM criteria with irritability as a core symptom, even in the absence of elation, grandiosity and episodicity (versus unmodified DSM criteria)
  • absence of “pure” BP disorder
    • almost always comorbid, making it difficult to discern what’s really going on
  • Episode Length

Q

Atypical presentation of child Bipolar Disorder

A
  • predominant mood often irritable
  • irritability may be persistent, severe, violent
  • “complex Cycling” (>80% are rapid cycling)
    - pattern of cycling may be ultrarapid (5-364 cyc/yr) or ultra radian (>365 cyc/yr)
    - ultraradian cycling is not considered an episode or cycle of mania, hypomania, or depression per DSM
    - recall that unstable and labile moods are typical of children <10 y.o
  • Comorbidity and family history are common (15% of first degree relatives
  • poor treatment response and recurrence
