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.
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 — 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.
Manic spending or days without sleep is medical emergency, not personality flaw — seek help early. If anxiety or stress is part of what you are coping with, brightloaf is a UK mental health app offering practical support, check-ins and short counselling sessions alongside other care.
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.
