Definition & Classification

Bipolar disorder is a chronic mood disorder characterised by episodic periods of mania/hypomania and depression, with periods of normal mood (euthymia) in between. It affects approximately 1–2% of the population worldwide.

DSM-5 Classification

TypeEpisodesKey Difference
Bipolar I≥1 manic episode (with or without depressive episodes)Full mania ≥7 days OR requiring hospitalisation; psychosis may occur
Bipolar II≥1 hypomanic + ≥1 major depressive episodeHypomania (4–6 days, less severe than mania); no psychosis
CyclothymiaChronic fluctuating hypo/depressive symptoms >2 yearsSymptoms below threshold for full episode diagnosis
Key distinction — Mania vs Hypomania: Mania lasts ≥7 days (or requires hospitalisation), significantly impairs function, may include psychosis. Hypomania lasts 4–6 days, is noticeable but does NOT cause marked impairment or require hospitalisation, with NO psychosis.

Aetiology & Risk Factors

Biological

  • Genetic: heritability ~60–80% (first-degree relative increases risk 10×)
  • Neurotransmitter dysregulation (dopamine, serotonin, noradrenaline)
  • Circadian rhythm disruption
  • HPA axis dysregulation (stress response)

Environmental Triggers

  • Sleep deprivation (major trigger for mania)
  • Life stressors, bereavement, significant events
  • Substance use (cannabis, stimulants, alcohol)
  • Antidepressants without mood stabiliser (can trigger mania)
  • Seasonal changes (light exposure)

Clinical Features Comparison

☀️ Manic Episode

Elevated/irritable mood ≥7 days

  • Grandiosity, inflated self-esteem
  • Decreased need for sleep (not tired after 3 hrs)
  • Pressured/rapid speech (talkativeness)
  • Flight of ideas, racing thoughts
  • Distractibility
  • Increased goal-directed activity
  • Risky behaviours (spending, sex, substances)
  • Psychosis (delusions, hallucinations) — Bipolar I

🌑 Depressive Episode

Depressed mood ≥2 weeks (5+ symptoms)

  • Persistent low mood
  • Anhedonia (loss of pleasure)
  • Changes in sleep (insomnia or hypersomnia)
  • Fatigue, loss of energy
  • Psychomotor agitation or retardation
  • Poor concentration
  • Feelings of worthlessness, guilt
  • Suicidal ideation (HIGH RISK)
Suicide risk in Bipolar Disorder: Lifetime suicide risk is 15–20x higher than general population. Assess suicide risk at every contact, especially during depressive phase, mixed states, and after a manic episode (post-manic depression).

Mixed States

Mixed features = simultaneous manic and depressive symptoms. Associated with highest suicide risk. Patient may have racing thoughts (mania) + hopelessness (depression) simultaneously — particularly dangerous combination as the patient has "energy" to act on suicidal thoughts.

Mnemonic — Manic Episode: DIG FAST

LetterFeature
DDistractibility
IImpulsivity / Irresponsible behaviours
GGrandiosity
FFlight of ideas
AActivity increased (goal-directed)
SSleep decreased (no fatigue despite minimal sleep)
TTalkativeness (pressured speech)

3 or more of DIG FAST criteria (with elevated/irritable mood ≥7 days causing impairment) = manic episode.

Lithium — The Gold Standard Mood Stabiliser

Lithium is the most effective prophylactic treatment for bipolar disorder and reduces suicide risk. However, it has a narrow therapeutic index — regular blood level monitoring is essential.

Lithium Therapeutic Levels

IndicationTarget Level (12-hour trough)
Acute mania treatment0.8–1.2 mmol/L
Maintenance / prophylaxis0.6–0.8 mmol/L
Elderly patients0.4–0.6 mmol/L (lower to reduce toxicity)
Blood sampling: Lithium levels must be taken 12 hours after the last dose (trough level). Levels taken at other times are meaningless. Frequency: weekly until stable, then every 3–6 months.

Lithium Toxicity — Levels & Features

Mild Toxicity (1.5–2.0 mmol/L)
  • Nausea, vomiting, diarrhoea
  • Coarse tremor (fine tremor is normal at therapeutic levels)
  • Thirst, polyuria
  • Mild drowsiness
Moderate Toxicity (2.0–2.5 mmol/L)
  • Confusion, drowsiness, ataxia
  • Slurred speech, muscle twitching
  • ECG changes (T wave flattening, QT prolongation)
Severe Toxicity (>2.5 mmol/L) — Medical Emergency
  • Seizures, coma
  • Cardiac arrhythmias
  • Renal failure
  • Treatment: haemodialysis

Factors That Increase Lithium Levels (Toxicity Risk)

Lithium Monitoring Schedule

TestFrequency
Serum lithium levelWeekly until stable; every 3–6 months maintenance
Renal function (U&E, eGFR)Every 6 months (lithium is nephrotoxic long-term)
Thyroid function (TSH)Every 6 months (lithium causes hypothyroidism in up to 40%)
CalciumAnnually (lithium can cause hypercalcaemia)
ECG (baseline)Before starting; if cardiac risk

Other Mood Stabilisers

DrugUseKey Monitoring / Concerns
Valproate (sodium valproate)Acute mania, prophylaxis (especially rapid cycling)TERATOGENIC — avoid in women of childbearing age; liver function; platelets; pancreatitis risk
LamotrigineBipolar depression prevention (not acute mania)Stevens-Johnson syndrome (SJS) risk — slow titration essential; never rapid dose increase
Quetiapine (atypical antipsychotic)Acute mania AND bipolar depressionMetabolic syndrome, weight gain, postural hypotension, QTc prolongation
OlanzapineAcute mania, agitationSignificant weight gain, metabolic syndrome, diabetes risk
HaloperidolAcute mania with psychosisEPS (extrapyramidal side effects), NMS risk
Valproate + women of childbearing potential: Sodium valproate causes neural tube defects (spina bifida) in up to 10% of pregnancies. In the GCC, valproate is subject to the same PREVENT programme restrictions as in the UK. All female patients must be on effective contraception and counselled annually about risks.

Nursing Management — Depressive Phase

Antidepressants alone are contraindicated in bipolar disorder without a concurrent mood stabiliser — they can trigger a manic switch. Always ensure a mood stabiliser is in place before any antidepressant.

GCC-Specific Considerations

Stigma & Help-Seeking in GCC Culture

Mental illness carries significant stigma in GCC societies. Patients and families may attribute bipolar symptoms to supernatural causes (jinn, evil eye/ayn) or spiritual weakness. Nurses should provide culturally sensitive education, involve religious and family support structures where appropriate, and work within the patient's cultural framework without dismissing religious beliefs. Many GCC countries have invested heavily in reducing mental health stigma (e.g., Saudi Arabia's Vision 2030 mental health initiatives).

Lithium & Ramadan Fasting

Lithium dosing during Ramadan requires careful management. Fasting reduces fluid intake during daylight hours and dramatically increases dehydration risk, especially in hot GCC summers. Dehydration increases lithium reabsorption and risks toxicity. Advise patients to: (1) maintain adequate fluid intake at Suhoor and Iftar, (2) check lithium levels before and during Ramadan, (3) consider dose timing adjustments with psychiatric team, (4) avoid NSAIDs during fasting. Some patients may need temporary dose reduction.

Heat, Sweating & Lithium Toxicity

GCC summer temperatures exceed 45°C. Excessive sweating causes sodium and fluid depletion, which reduces renal lithium clearance — increasing lithium levels. Patients on lithium must be educated to stay hydrated, avoid prolonged outdoor exposure in summer, maintain adequate salt intake (low-sodium diets increase lithium reabsorption), and seek medical review if they develop diarrhoea, vomiting, or febrile illness.

Family Involvement & Collectivist Decision-Making

GCC cultures are predominantly collectivist — family involvement in healthcare decisions is expected and valued. In bipolar management, family psychoeducation is crucial: recognising early warning signs of mania or depression, preventing medication non-compliance, and supporting recovery. Male family members (wali/guardian) may be involved in consent and discharge decisions for female patients. Nurses should navigate these dynamics while respecting patient autonomy within institutional guidelines.

Substance Use & Bipolar Comorbidity

While alcohol use is less common in GCC Muslim populations, khat (qat) chewing is prevalent among East African and Yemeni communities in some GCC countries and is a stimulant that can trigger mania. Cannabis use is also documented among younger GCC residents and can worsen bipolar instability. Nurses should include substance use screening in all bipolar assessments without cultural judgment.
