3. cyclothymic

4. substance/medication-induced

5. due to another medical condition

2

bipolar type 1

must meet criteria for a manic episode

  • may be preceded or followed by hypomanic or major depressive episodes

3

what is a manic episode?

  1. elevated (euphoric/infectious), expansive, or irritable mood
  2. persistently increased goal-directed activity or energy

  • flight of ideas
  • distractibility
  • incr in goal directed activity or psychomotor agitation
  • engagement in pleasurable but potentially harmful behavior

 

NOT ATTRIBUTABLE to substance/med condition

4

what is a hypomanic episode

diff from mania is in degree of intensity of sx and impairment

  • lite version of mania
  • must last at least 4 days

doesn't have to result in hospitalization, can go on for years

almost always followed by depression

 

behavior not characteristic of the individual

observable by others

doesn't cause marked impairment

NOT ATTRIBUTABLE to substance/medical cond

  • presentation with psychotic features more likely within second episode or with hx of MDD/bipolar

12

specifies for bipolar/related disorders

 

with seasonal pattern

regular relationship with onset of hypomanic/manic/depression and time of year (fall/winter)

  • full remission or switch to depression/hypomania/mania occurs at a characteristic time of year
  • last 2 years, 2 episodes without episodes at other times of year
  • more seasonal than non-seasonal depressions

13

bipolar disorders ddx

  • MDD
  • cyclothymic disorder
  • GAD, panic, PTSD
  • medical/substance-induced states
  • schizophrenia
  • ADD/ADHD
  • personality disorders

14

bipolar type 1

course

67-75% of bipolar 1 case have depression as first episode

10-20% have manic episodes only

  • manic episodes can last 3mo
  • 90% of pt have more than one episode
  • time between episodes can decrease

5-15% are rapid cyclers

90% of pt never fully remit

15

bipolar disorder type 1

prognosis

poorper prognosis than MDD alone

poorer prognosis:

  • young age of onset
  • alcohol dependence
  • psychotic ft
  • lack of interepisode remission
  • male gender
  • poor social supports

good signs: short manic episodes, no comorbidity, older age of onset, good social supports

 

30% show severe impairment lifetime

16

bipolar disorder type 1

comorbidity

  • anxiety disorder (75% patients)
  • ADHD, impulse control or conduct disorder
  • substance use disorders (50%)
  • metabolid syndrome, migraines

17

bipolar disorder type 2

course and prognosis

onset: mid20s

  • 5-15% will ultimately develop a manic episode

initial episode may be depressive; more time is spent in depressive episodes

15-20% may not recover between episodes

 

occupational cognitive decline

18

bipolar disorder type 2

risk, prognosis, gender

risk highest among relatives

10-20% of postpartum women may experience a hypomanic episode

 

risk: rapid cycling

good signs: late age of onset, higher education, marriage

19

bipolar 2 and suicide

1/3 of patients report a suicide attempt

lethality of attempt potentially greater in type 2 than type 1

 

20

pharmacologic tx of bipolar 1 and bipolar 2

1. mood stabilizers

2. ECT

3. v v cautious use of antidepressants

  • caution because can swing patients into hypo/mania → will inevitably swing back into depression

21

mood stabilizers for bipolar 1/2

  • lithium carbonate
  • antiepileptic drugs (valproate/valproic acid, carbamazepine, lamotrigine)
  • atypical antipsychotics (olanzapine, risperidone, quetiapine, aripiprazole, lurasidone)

22

psychotherapeutic tx for bipolar 1/2

  • crisis intervention
  • supportive psychotherapy
  • cognitive behavioral therapy
  • family therapy

23

cyclothymia

chronic, fluctuating disorder of at least 2 yr duration marked by many periods with hypomanic sx that dont meet bipolar 2 criteria and many periods of depressive sx that dont meet criteria for MDD

  • sx present for at least half of 2 years of hypomania and minor depression
    • diff from bipolar2 bc depression is NOT MAJOR
  • periods are usually brief, unpredictable, and change abruptly
  • irritability is common

longest period free of sx: 2mo

 

v rarely diagnosed

  • most common in 15-25 yr olds
  • good chance that it will progress to bipolar 1 or 2
  • potentially more sensitive to "switching" to hypo/mania with antidepressants

24

cyclothymic disorder tx

similar to that of major depression or bipolar illness

  • be even more cautious with antidepressants → more sensitive to switching into hypo/mania

25

substance/med-induced bipolar/related disorders

 

elevated, expansive, irritable mood with evidence that mood change is direct consequence of/temporally related to a substance or medication

  • medication, toxic substance, illicit substance (stimulants, PCP, steroids)

26

factors associated with depression in primary care

  • compaints in multiple organ systems (neuro, GI, cardiac)
  • recurrent emotionality
  • sleep disturbances
  • frequent/urgent visits
  • chronic pain
