What are the symptoms of bipolar disorder?
Answered by Dr. Nitnem Singh Sodhi · Consultant Psychologist & Psychotherapist · Updated 2026-05-22
Short answer
Bipolar disorder involves distinct episodes of elevated mood (mania or hypomania — reduced sleep need, racing thoughts, grandiosity, risky behaviour) alternating with depressive episodes. Diagnosis requires a psychiatric assessment; mood swings alone are not bipolar.
Bipolar is one of the most misused words on the internet. Clinically it has a precise meaning, and confusing it with everyday mood swings does real harm — both to people who have it and people who don't.
Manic / hypomanic episode
Lasting at least 4 days (hypomania) or 7 days (mania): markedly reduced need for sleep, racing thoughts, pressured speech, grandiosity, distractibility, increased goal-directed activity, risky decisions (spending, sexual, driving). Mania impairs functioning; hypomania does not.
Depressive episode
Two or more weeks of low mood, anhedonia, fatigue, sleep change, appetite change, worthlessness, suicidal thinking — same as unipolar depression but in someone who has had episodes of the other end.
What to do
If you suspect bipolar in yourself or a family member, please book a psychiatric assessment — not a counsellor, not the AI alone. Bipolar is highly treatable with the right combination of medication and structured psychological work, but accurate diagnosis is essential because antidepressants alone can worsen it.
