Many people with bipolar disorder first see a doctor during a depressive phase. If past 'high' periods are not recognised, treatment may be less effective.

Family members often notice highs that the person does not remember as a problem.

Frequently asked questions

Can a self-test tell me if I have bipolar disorder?

No. Screening can raise suspicion, but diagnosis needs a clinical assessment, ideally with family input.

Is bipolar disorder lifelong?

It is usually long-term, but with treatment most people stay well for long periods and live full lives.
