Bipolar disorder Flashcards

1
Q

You are on your emergency medicine rotation when Ben, a 22 yo M is brought into the ER by police. His OP psychiatry PA initiated the crisis response team due to concerns at his visit. He is talking rapidly and loudly about his plans for the country as he is the president. You attempt to interview him, but he is constantly changing subjects and is easily distracted. You learn he has slept less than 2 hours per night for the past 8 days. You ask what he’s been doing and he states “I’ve been planning my campaign for mayor!! I already ordered $10,000 in merchandise!.” He can be seen speaking out loud, as if to someone.

Q

bipolar

RF

A

Bipolar I
6-7% die from suicide
Highest risk immediately after hospital discharge
VERY heritable (73-93%)

Bipolar II
Hypomania causes less impairment but depressive episodes tend to be more severe
1 in 3 will attempt suicide, completion rates equal to bipolar I.
Will have several depressive episodes before a hypomanic one, hard to dx
5-15% will end of up having a manic episode → change to Bipolar I d/o

Lifetime suicide risk is 15x higher than general population
Bipolar disorder accounts for ¼ of suicide deaths

60% will have 3 or more comorbid disorders - anxiety and SUD are the highest

40% will develop an eating disorder

Q

Bipolar 1 Criteria A
Time frame

A

Criteria A
A distinct period of abnormally and persistently elevated, expansive, or irritable mood AND

Abnormally and persistently increased activity or energy, lasting at least 7 days and present most of the day, nearly every day (or any duration if hospitalization is necessary).

The episode requires hospitalization to prevent harm to self or others, or psychotic features.

The episode is not attributable to the physiological effects of a substance (e.g. a drug of abuse, a medication, other treatment) or to another medical condition.

Not better explained by schizophrenia, schizoaffective disorder, schizophreniform disorder, or delusional disorder

NOTE: Bipolar I does NOT require a MDD dx. However, this is rarely an occurrence.

Q

Mania Criteria (DIGFAST)

A

B: During the period of mood disturbance and increased energy and activity, at least 3 of the following symptoms have persisted (4 symptoms if the mood is only irritable), represent a noticeable change from usual behaviour, and have been present to a significant degree:

Distractibility (i.e. - attention too easily drawn to unimportant or irrelevant external stimuli), as reported or observed.
Indiscretion/Impulsivity, characterized by excessive involvement in activities that have a high potential for painful consequences (e.g. - unrestrained buying sprees, sexual behaviours, or foolish business investments).
Grandiosity or inflated self-esteem.
Flight of ideas or subjective experience that thoughts are racing.
Activity (goal-directed) increasing (e.g. - either socially, at work or school, or sexually) or psychomotor agitation.

Q

Bipolar II

more

A

Depressive episodes are likely to cause more impairment than hypomanic episodes.

Q

Cyclothymic Disorder

general

A

For at least 2 years, (or 1 year in kids), there have been numerous periods with hypomanic symptoms that do not meet criteria for hypomanic episode and numerous periods with depressive symptoms that do not meet criteria for major depressive episode
●During this 2 year period, the hypomanic and depressive symptoms have been present for at least half the time and the individual has not been without symptoms for more than 2 months at a time
●Not attributable to effects of a substance or medical condition
●Sxs cause clinically significant distress or impairment
●15-50% risk cyclothymia will go on to develop Bipolar 1 or 2 disorder

***Bipolar version of dysthymia (MDD)

●There is evidence from the hx, PE, and lab findings of both:
○The sxs developed during or soon after substance intoxication or withdrawal or after exposure to a medication.
○The involved substance is capable of producing the sxs

19
Q

Diagnostic Clinical Tips

A

If patient states they have bipolar d/o, still ask full mania hx to confirm

Mood changing by the hour and situation related → think BPD

If SSRIs are not working → consider bipolar d/o

If SSRI’s trigger mania → Bipolar d/o

Depressive episodes in childhood/adolescence → keep bipolar d/o on your radar. ⅔ of bipolar patients have a major mood disorder in childhood/adolescence

Can be hard to distinguish as it can look like and occur simultaneously with drug use, ADHD and BPD. (and even NPD… very had to distinguish)

20
Q

Bipolar Disorder Treatment

A

Mood Stabilizers
Antipsychotics (atypical)
Typically, a combo of both!
ECT, Clozaril in severe cases

seroquel is always the right answer

21
Q
A
22
Q

Gold standard for Bipolar

A

Lithium

indicated for mania and maintenance
Off label - bipolar depression

can take 1-2 weeks to become effective (augment with valproate or atypical antipsychotics)

Can reduce risk of suicide completion (8x less)
VERY effective, 80% of patients respond well

23
Q

Lithium Side Effects

A

nausea/diarrhea (take w/meals, split dosing, ER)
Tremor (propranolol)
polyuria/polydipsia (dose at bedtime)
Hypothyroidism
(7-9%, 9x more likely in women, tx: levothyroxine)
nephrotoxicity (diabetes insipidus
Weight gain
Memory problems
Edema
Rarely - EKG abnormalities

24
Q

Lithium Monitoring

A

Check Li level, BUN/creatinine, electrolytes, TSH/T3/T4, EKG (over 50), Preg test
Recheck 1 week + 1 month after initiation. Maintenance q 6-12 months
Check Li level 1 week after changing doses - 12 hours after last Li dose
Once level achieved, check q 3 months for 6 months
Once stable, check q 6-12 months
Monitor for metabolic effects (BMI, lipids, etc)
Compliance/access to labs can be an issue

25
Q

Lithium Contraindications

A

Severe renal impairment
Myasthenia gravis
1st trimester and breastfeeding mothers
Teratogenic - Ebstein Anomaly

AVOID: NSAIDs, ACE inhibitors, HCTZ (increase Li level)
Excess sweating, low Na diet and dehydration will increase Li levels

26
Q

Lamotrigine (Lamictal)

A

MOA: Sodium channel blocker, Anticonvulsant
Indicated for bipolar maintenance, off label for depression
Starting dose: 25mg x 14 days. “Max”: 200mg
Best if split BID (100mg BID), takes about 8 weeks to get to target dose
Side effects: dizziness, headaches, benign rash (7%) diplopia, blood dyscrasias, withdrawal seizures if abruptly d/c,
If miss 5+ doses in a row, must start back at 25mg q daily
Stevens Johnsons Syndrome (SJS) - 1 in 1000 patients, but can be lethal
Valproate can DOUBLE lamotrigine levels
Levels are lowered by oral contraceptives, so may need higher dose in women taking OCP. Levels can be higher during “placebo” week

27
Q
A
28
Q

Valproic acid/valproate (Depakote)

A

Anticonvulsant indicated for bipolar mania (off label good for rapid cycling)
Starting dose: 250-500mg/day, rapidly titrate up
Max dose: 4000mg/day
serum level 50-125 ug/mL (aim for 100)
Check 5 days after increase and q 6 months
Side effects: somnolence, nausea, fatigue, dizziness, hair loss, tremor, thrombocytopenia, hyperammonemia (confusion)
ER formulation absorbs 20% less valproate
BBW:
Pancreatitis (can be life threatening)
Hepatic necrosis (can be life threatening)
EXTREMELY TERATOGENIC (NTD/spina-bifida and low IQ scores, decreases folate)

29
Q

Carbamazepine (Equetro/Tegretol*)

A

MOA: sodium channel blocker (anticonvulsant)
Indicated for acute mania, off label for maintenance
Starting dose: 200mg BID, Max: 800mg BID
Side Effects: dizziness, somnolence, nausea, headache
Rare: agranulocytosis, aplastic anemia, hepatic failure, SIADH, SJS/TEN
Will decrease OCP effectiveness
*NOT APPROVED FOR PSYCH (Tegretol)

30
Q

Bipolar Tx Takeaways

A

Almost all SGAs will treat mania. Choose based on side effects, comorbidities and past med trials.
Seroquel will treat mania, maintenance and depression
Vraylar will treat mania, mixed and depression.
Only bipolar depression tx include: Seroquel, Latuda, Vraylar and Symbyax (olanzapine/fluoxetine).

Why not SSRIs/SNRIs??
Not typically effective and can trigger mania in some patients
Will sometimes with in bipolar II with concurrent mood stabilizer

31
Q

Tx Clinical Tips

A

Acute mania → think lithium and/or depakote +/- SGA
Depression → think lamotrigine (off label) + approved antipsychotic
Rapid cycling → Seroquel is a good option
Augment with antipsychotics, they work faster!
Bipolar II can sometimes be treated with SSRIs + mood stabilizer
You may need to tx other conditions such as ADHD, anxiety, SUD.
