## Quick answer

What is bipolar disorder? Bipolar disorder causes extreme mood swings — manic or hypomanic highs (elevated mood, reduced sleep, risky behaviour) alternating with depressive lows. Types include bipolar I (full mania) and bipolar II (hypomania plus depression). Treatment combines mood stabilisers like lithium, antipsychotics, and psychological therapy. See a GP if mood swings severely disrupt life — urgent help if psychotic, suicidal, or not sleeping for days with reckless behaviour.

## Key facts about bipolar disorder

- Bipolar affects roughly 1 in 50 people — often starts in late teens or twenties.
- Mania includes elevated mood, reduced need for sleep, grandiosity, and risky spending or sexual behaviour.
- Depression in bipolar can be severe — antidepressants alone may trigger mania without mood stabiliser cover.
- Lithium remains a gold-standard mood stabiliser — requires blood level monitoring.
- Lifelong condition — but most people achieve stability with treatment and self-management.

## Bipolar disorder — beyond ordinary mood swings

**Bipolar disorder** (formerly manic depression) is a **serious mental health condition** causing **extreme mood episodes** — **highs (mania/hypomania)** and **lows (depression)** — separated by **periods of relative stability**.

Affects roughly **1 to 2%** of population — onset typically **late teens to early 30s** — often **delayed diagnosis** because first episode may be depression.

## Types

### Bipolar I

- ≥1 manic episode — lasting ≥7 days (or any duration if hospitalised)

- mania may include psychosis

- depressive episodes common

### Bipolar II

- hypomania — ≥4 days — elevated mood/energy without full mania severity or psychosis

- ≥1 major depressive episode

- not “milder bipolar” — depression often disabling

### Cyclothymia

- chronic fluctuating moods — hypomanic and depressive symptoms < full criteria — ≥2 years

## Mania and hypomania — signs

**MANIA (more severe):**

- euphoria or irritability

- decreased sleep need — “feel fine on 2 hours”

- grandiosity — unrealistic plans, spending

- racing thoughts , pressure of speech

- risky behaviour — sex, drugs, finances, driving

- psychosis possible — delusions of grandeur

**HYPOMANIA:**

- similar but shorter , no psychosis , less impairment

- may feel productive — others notice change

**Lack of insight** common during mania — **family often spot first**.

## Depressive episodes

Like [major depression](https://healthanswers.co.uk/conditions/depression/) — low mood, anhedonia, fatigue, guilt, suicidal thoughts — often **more prolonged** and **treatment-resistant** without mood stabiliser.

## Diagnosis

**Psychiatric assessment** — GP refers to **community mental health team** or **psychiatrist**.

**Mood diaries** help — date, sleep, energy.

**Exclude:**

- substance-induced — cocaine, steroids, antidepressant-induced mania

- thyroid disease

- ADHD overlap — different chronic pattern

## Treatment

### Mood stabilisers

**Lithium:**

- gold standard for mania prevention

- narrow therapeutic index — blood levels, thyroid, renal monitoring

**Valproate:**

- effective — teratogenic — not in women of childbearing potential without contraception programme

**Lamotrigine:**

- better for depression prevention — slow titration — rash risk

### Antipsychotics

**Quetiapine, olanzapine, aripiprazole** — acute mania and **maintenance**

### Antidepressants

**Use cautiously** — **with mood stabiliser** — can **trigger mania/hypomania** if alone

### Psychological

**Psychoeducation**, **CBT**, **interpersonal social rhythm therapy** — **regular sleep/wake** prevents relapse

## Crisis and safety

**Mania emergency:**

- dangerous behaviour

- psychosis

- exhaustion from no sleep

**Depression emergency:**

- suicidal ideation — 999 / crisis team

**Advance statements** — care preferences when well

## Living with bipolar

- sleep hygiene — #1 relapse trigger is sleep loss

- avoid drugs/alcohol

- MedicAlert , trusted contacts

- Bipolar UK — peer support

**Not a life sentence to chaos** — **most achieve long stability** with tailored medication and lifestyle rhythm.

## ! When to see a GP about bipolar disorder

See a GP if you have episodes of unusually high energy with little sleep alternating with deep depression. Go to A&E or phone 999 if suicidal, psychotic (hearing voices, delusions), or behaving dangerously during a high — spending life savings, driving recklessly. Crisis teams support severe episodes — do not stop mood stabilisers suddenly without medical advice.

## Common questions about bipolar disorder

What is the difference between bipolar I and bipolar II? Bipolar I — at least one full manic episode (hospital-level severity possible) — depressive episodes common but not required for diagnosis. Bipolar II — hypomania (less severe mania — no psychosis, shorter) plus major depressive episodes — hypomania can still impair relationships and work. What does a manic episode feel like? Persistently elevated or irritable mood, increased energy, reduced need for sleep (feel rested on 3 hours), racing thoughts, talking fast, grandiose plans, impulsive spending, sexual risk-taking, or starting unrealistic projects. Judgment impaired — often lack insight until episode ends. Is bipolar disorder the same as mood swings? No — normal mood swings are brief and tied to events. Bipolar episodes last days to weeks or months — mania/hypomania meets specific criteria with functional impairment. Borderline personality disorder involves rapid mood shifts over hours — different diagnosis. How is bipolar disorder treated? Mood stabilisers — lithium, valproate, lamotrigine (maintenance especially); antipsychotics — quetiapine, olanzapine for mania or maintenance; psychological therapy — CBT, psychoeducation, family-focused therapy. Antidepressants only with mood stabiliser cover — can trigger mania alone. Can people with bipolar work normally? Many do with stable treatment — some need occupational adjustments during recovery. Discrimination is unlawful — disclose only if choosing to. Relapse prevention — sleep regularity, stress management, medication adherence — critical. What is the best mood stabiliser for bipolar disorder? There is no single best mood stabiliser for everyone. Lithium has the strongest evidence for preventing both manic and depressive episodes and is often seen as the gold standard, but it needs regular blood tests. Valproate, lamotrigine and some antipsychotics such as quetiapine are alternatives, chosen to suit your symptoms, other health conditions and pregnancy plans. A psychiatrist will tailor this to you.
