Lesson
Diagnose the Course, Not the Mood
Bipolar disorders are longitudinal illnesses defined by episodes, severity, impairment, and exclusions. A patient may present in depression while the diagnostic evidence lives in a past period of elevated energy and reduced sleep.
- Bipolar I
- Bipolar II
- Mania
- Hypomania
- Depression
diagnosis episode map
Balance acute control, long-term prevention, safety, and function.
Distinguish mania and hypomania
Both require a distinct period of elevated, expansive, or irritable mood and increased energy. Mania causes marked impairment, psychosis, or hospitalization, while hypomania does not.
Assign subtype correctly
One manic episode establishes bipolar I even without major depression. Bipolar II requires hypomania and major depression with no history of mania.
Use mixed-features language
Concurrent symptoms from the opposite pole can occur during mania, hypomania, or depression and can increase agitation, distress, and suicide risk.
Test alternatives
Review substances, steroids, stimulants, antidepressants, thyroid or neurologic disease, ADHD, trauma, personality, schizophrenia-spectrum disorders, delirium, and sleep deprivation.

Lesson
Stabilize Risk Before Refining the Regimen
Mania and mixed states can produce suicide risk, aggression, exploitation, spending, unsafe sex, driving risk, dehydration, exhaustion, psychosis, and loss of self-care.
- Suicide
- Psychosis
- Impulse
- Sleep
- Capacity
safety triage
Balance acute control, long-term prevention, safety, and function.
Ask directly about suicide
Energy and impulsivity can coexist with hopelessness. Assess thoughts, intent, plan, means, prior behavior, intoxication, agitation, and protective factors.
Assess behavioral exposure
Clarify spending, contracts, travel, sexual risk, driving, aggression, substances, weapons, sleep, food, fluids, and vulnerability to exploitation.
Identify medical urgency
Severe agitation, delirium, intoxication, withdrawal, hyperthermia, dehydration, rhabdomyolysis, pregnancy, and medication toxicity can require medical stabilization.
Use the least restrictive safe setting
Hospitalization is appropriate when danger, grave disability, psychosis, severe sleep loss, or inability to collaborate makes outpatient care unsafe.

Lesson
Control Mania Without Losing the Maintenance Plan
Acute treatment should calm dangerous activation, restore sleep, reduce psychosis, and create a regimen that can continue after the crisis when appropriate.
- Lithium
- Quetiapine
- Valproate
- Antipsychotic
- Combination
acute mania
Balance acute control, long-term prevention, safety, and function.
Use current preferred monotherapies
The 2023 VA/DoD guideline suggests lithium or quetiapine as monotherapy for acute mania because each has acute and recurrence-prevention evidence.
Escalate severe episodes
Severe mania, psychosis, dangerous behavior, or marked impairment often warrants an antipsychotic combined with lithium or valproate while monitoring cumulative adverse effects.
Use alternatives deliberately
Valproate, selected SGAs, carbamazepine, and other options may fit prior response or clinical characteristics. Reproductive, hepatic, metabolic, cardiac, and interaction risks shape selection.
Do not use lamotrigine for acute mania
Slow titration and the absence of acute antimanic efficacy make lamotrigine unsuitable as rescue therapy.

Lesson
Treat Depression Without Destabilizing the Course
Bipolar depression is not unipolar depression with an added label. Treatment must account for mania history, mixed symptoms, switching, cycle acceleration, and phase-specific evidence.
- Quetiapine
- Lurasidone
- Lumateperone
- Cariprazine
- Switch risk
bipolar depression
Balance acute control, long-term prevention, safety, and function.
Use episode-specific evidence
Evidence-supported options can include quetiapine, lurasidone, cariprazine, lumateperone, olanzapine-fluoxetine, lithium, and lamotrigine depending on diagnosis, prior response, and guideline or label context.
Distinguish acute and preventive evidence
Lamotrigine has stronger value for preventing depressive recurrence than for rapidly treating a severe acute episode. Quetiapine has evidence across acute depression and recurrence prevention.
Avoid antidepressant monotherapy in bipolar I
If an antidepressant is considered, use it only in a carefully selected patient with an appropriate mood-stabilizing regimen, active switch monitoring, and a stop plan.
Watch for emerging activation
Reduced need for sleep, increased energy, pressured speech, irritability, racing thoughts, impulsivity, or mixed symptoms require rapid reassessment.

Lesson
Prevent Both Poles and Preserve Function
Maintenance treatment should reflect the patient's dominant polarity, severe consequences, prior response, adverse effects, adherence, comorbidity, and reproductive goals.
- Recurrence
- Polarity
- Lithium
- Quetiapine
- Lamotrigine
maintenance
Balance acute control, long-term prevention, safety, and function.
Prefer broad evidence when it fits
VA/DoD recommends lithium or quetiapine for preventing mania and recommends lamotrigine for preventing bipolar depressive recurrence.
Continue what worked selectively
An effective acute agent is often a rational maintenance foundation, but rescue sedatives, high-burden combinations, or short-term antipsychotic intensity may need reassessment.
Define duration and monitoring
Bipolar disorder is commonly recurrent and often requires long-term treatment. Use shared decisions and planned metabolic, renal, thyroid, movement, reproductive, and functional review.
Build an early-warning plan
Identify each person's changes in sleep, energy, spending, speech, irritability, withdrawal, substances, and medication behavior, plus the action and contact for each signal.

Lesson
Treat Lithium as a Physiologic System
Lithium has a narrow therapeutic index, renal elimination, sodium-linked handling, and endocrine, kidney, cardiac, neurologic, and reproductive effects.
- Trough
- Kidney
- Thyroid
- Calcium
- Sodium
lithium system
Balance acute control, long-term prevention, safety, and function.
Obtain an interpretable level
A maintenance level is usually drawn near 12 hours after the last dose after steady state. Document the exact dose time, draw time, formulation, schedule, and recent missed doses.
Monitor the whole system
Assess renal function, thyroid function, calcium, electrolytes, weight, pregnancy context, and cardiac risk, with frequency individualized to stability and comorbidity.
Counsel consistency
Maintain adequate fluid and a reasonably consistent sodium intake. Fever, heavy sweating, vomiting, diarrhea, reduced intake, or acute illness can change exposure.
Use formulation equivalence carefully
Five milliliters of lithium citrate provides 8 mEq lithium ion, equivalent to 300 mg lithium carbonate. Verify the actual product concentration before conversion.

Lesson
Interrupt the Toxicity Spiral Early
Dehydration, sodium loss, kidney injury, thiazides, ACE inhibitors, ARBs, and many NSAIDs can reduce lithium clearance and create a self-amplifying neurologic and gastrointestinal syndrome.
- Interaction
- Volume
- Tremor
- Ataxia
- Dialysis
lithium toxicity
Balance acute control, long-term prevention, safety, and function.
Differentiate common effects from toxicity
Fine tremor, thirst, polyuria, and mild nausea can occur during therapy. Coarse tremor, persistent vomiting or diarrhea, ataxia, dysarthria, confusion, myoclonus, seizure, or declining consciousness are danger signs.
Stop and assess
Hold lithium, obtain an immediate level, renal function, electrolytes, ECG, volume assessment, medication history, and serial neurologic examination.
Use interaction logic
Thiazides, ACE inhibitors, ARBs, and many NSAIDs can raise exposure. Caffeine or sodium changes can alter levels, but no simple list replaces measured follow-up.
Escalate severe poisoning
Use poison-center or toxicology support and involve nephrology for severe symptoms, kidney failure, high or rising levels, or anticipated rebound. Hemodialysis decisions integrate the whole clinical picture.

Lesson
Use Each Mood Stabilizer for Its Actual Strength
Valproate, lamotrigine, and carbamazepine have different episode roles, kinetics, interactions, monitoring, and reproductive risks.
- Valproate
- Lamotrigine
- Carbamazepine
- Rash
- Induction
anticonvulsants
Balance acute control, long-term prevention, safety, and function.
Use valproate with safeguards
Valproate can treat selected mania but requires liver, platelet, weight, interaction, pregnancy, pancreatitis, and hyperammonemia assessment. Avoid during pregnancy or planned pregnancy for bipolar disorder unless alternatives fail or are unacceptable.
Titrate lamotrigine slowly
Serious rash risk rises with rapid titration, high starting doses, and valproate coadministration. A prolonged interruption may require restarting the titration.
Respect carbamazepine complexity
Autoinduction changes its own exposure, while CYP induction lowers many drugs, including hormonal contraception. Monitor blood counts, liver function, sodium, dermatologic risk, and interactions.
Use pharmacogenomics when indicated
HLA-B*15:02 and HLA-A*31:01 can inform severe cutaneous-reaction risk in relevant ancestry and clinical contexts. Testing does not replace rash counseling.

Lesson
Match the Antipsychotic to the Episode
Antipsychotic evidence is phase and product specific. Metabolic, movement, prolactin, QT, sedation, orthostasis, interaction, and formulation burdens determine whether efficacy is sustainable.
- Mania
- Depression
- Metabolic
- Movement
- LAI
antipsychotics
Balance acute control, long-term prevention, safety, and function.
Use acute mania evidence
Quetiapine and several other SGAs have acute antimanic efficacy. Severe mania may need combination with lithium or valproate.
Use bipolar depression evidence
Quetiapine, lurasidone, cariprazine, lumateperone, and olanzapine-fluoxetine have specific bipolar-depression evidence or labeling, but their metabolic and neurologic profiles differ.
Plan metabolic prevention
Record weight, blood pressure, glucose or A1c, lipids, diet, activity, and cardiovascular risk. Begin prevention rather than waiting for advanced disease.
Use LAIs for a defined purpose
Long-acting formulations may support preference and adherence, but product-specific loading, overlap, injection interval, renal limits, and missed-dose rules still apply.

Lesson
Plan Before Pregnancy and Before Delivery
Bipolar disorder can relapse severely during pregnancy and especially postpartum. Medication changes must compare untreated illness with drug-specific fetal, neonatal, maternal, and lactation risks.
- Valproate
- Lithium
- Lamotrigine
- Postpartum
- Sleep
perinatal care
Balance acute control, long-term prevention, safety, and function.
Avoid valproate when possible
Valproate has major structural and neurodevelopmental risks and should generally not be used for bipolar disorder during pregnancy or planned pregnancy unless alternatives fail or are unacceptable.
Individualize lithium
Lithium has fetal cardiac and neonatal concerns, but abrupt cessation can produce serious relapse. Use shared decisions, dose and level monitoring, changing renal physiology, fetal assessment, delivery planning, and postpartum dose review.
Use lamotrigine with kinetic awareness
Pregnancy can increase lamotrigine clearance and postpartum clearance can fall quickly. Symptoms, levels when used, and dose changes require coordinated review.
Prevent postpartum relapse
Protect sleep, arrange support for feeding and nighttime care, plan medication before delivery, educate about mania and psychosis, and schedule rapid follow-up. Postpartum psychosis is an emergency.

Lesson
Stabilize the Rhythms That Stabilize Mood
Sleep loss, irregular routines, stress, substances, relationship conflict, and disrupted treatment access can precede episodes and are legitimate treatment targets.
- Sleep
- Social rhythm
- Family
- Substances
- Psychoeducation
psychosocial rhythm
Balance acute control, long-term prevention, safety, and function.
Use evidence-based psychotherapy
Psychoeducation, family-focused therapy, interpersonal and social rhythm therapy, CBT, and recovery-oriented care can improve adherence, coping, function, and recurrence prevention.
Protect sleep without oversimplifying
Track reduced need for sleep as a manic sign, insomnia as a symptom, and schedule disruption as a trigger. Treat sleep disorders and avoid destabilizing sedative patterns.
Address substances directly
Alcohol, cannabis, stimulants, and other substances can mimic, trigger, worsen, or obscure episodes and can interact with treatment.
Invite support with consent
Family or chosen supports can help recognize early changes, protect finances and safety, support routines, and implement a crisis plan.
