Manic and depressive episodes, mood stabilisers, lithium toxicity, de-escalation, and GCC cultural considerations
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.
| Type | Episodes | Key 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 episode | Hypomania (4–6 days, less severe than mania); no psychosis |
| Cyclothymia | Chronic fluctuating hypo/depressive symptoms >2 years | Symptoms below threshold for full episode diagnosis |
Elevated/irritable mood ≥7 days
Depressed mood ≥2 weeks (5+ symptoms)
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.
| Letter | Feature |
|---|---|
| D | Distractibility |
| I | Impulsivity / Irresponsible behaviours |
| G | Grandiosity |
| F | Flight of ideas |
| A | Activity increased (goal-directed) |
| S | Sleep decreased (no fatigue despite minimal sleep) |
| T | Talkativeness (pressured speech) |
3 or more of DIG FAST criteria (with elevated/irritable mood ≥7 days causing impairment) = manic episode.
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.
| Indication | Target Level (12-hour trough) |
|---|---|
| Acute mania treatment | 0.8–1.2 mmol/L |
| Maintenance / prophylaxis | 0.6–0.8 mmol/L |
| Elderly patients | 0.4–0.6 mmol/L (lower to reduce toxicity) |
| Test | Frequency |
|---|---|
| Serum lithium level | Weekly 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%) |
| Calcium | Annually (lithium can cause hypercalcaemia) |
| ECG (baseline) | Before starting; if cardiac risk |
| Drug | Use | Key Monitoring / Concerns |
|---|---|---|
| Valproate (sodium valproate) | Acute mania, prophylaxis (especially rapid cycling) | TERATOGENIC — avoid in women of childbearing age; liver function; platelets; pancreatitis risk |
| Lamotrigine | Bipolar depression prevention (not acute mania) | Stevens-Johnson syndrome (SJS) risk — slow titration essential; never rapid dose increase |
| Quetiapine (atypical antipsychotic) | Acute mania AND bipolar depression | Metabolic syndrome, weight gain, postural hypotension, QTc prolongation |
| Olanzapine | Acute mania, agitation | Significant weight gain, metabolic syndrome, diabetes risk |
| Haloperidol | Acute mania with psychosis | EPS (extrapyramidal side effects), NMS risk |
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 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.
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.
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.
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.
Q1. A patient on lithium presents with coarse tremor, confusion, ataxia, and slurred speech. Their lithium level is 2.2 mmol/L. What is the appropriate management?
Q2. A nurse is educating a patient on lithium about risks during Ramadan fasting. Which instruction is MOST important?
Q3. Which mood stabiliser is CONTRAINDICATED in women of childbearing age without highly effective contraception due to teratogenicity?
Q4. A patient in an acute manic episode is pacing, talking rapidly, and becoming increasingly agitated. Which nursing approach is MOST appropriate?
