Look for changes from their usual pattern
Possible signs of a high mood include having lots of energy, needing less sleep, talking quickly, feeling overconfident, being impulsive or spending unusually large amounts of money. Someone may also become irritable or experience hallucinations or unusual beliefs.
One change on its own does not tell you what is happening. Compare it with the person's usual pattern and any warning signs they have identified themselves.[2]
What you can do now
- Use short, calm sentences. Deal with one practical point at a time.
- Name what you have noticed. Describe sleep, spending, risk-taking or changes in speech without trying to win an argument about a diagnosis.
- Use the agreed plan. If they previously asked you to contact someone or help with money during a high, follow that agreement.
- Ask for an urgent assessment if you suspect mania. You can seek advice even if they refuse; do not try to force them into an assessment yourself. Professionals must consider consent and any legal exceptions. Describe the changes to their team, if known, or use the urgent-help route. Say if you cannot safely provide the support they need.[3]
Money and commitments
Use any money safeguards they agreed while well. If there is no agreement, ask their care team for advice about the immediate concern. Planning ahead explains options to agree together.
If no plan exists, avoid taking control of accounts, cards or property on your own. Ask their care team for help and use independent debt or legal advice where needed.[4]
If they seem paranoid or are hearing or seeing things
Use the psychosis conversation guidance: acknowledge the fear, do not argue about the belief and do not pretend that you share it.
