You can encourage an adult, but usually cannot make them accept assessment or treatment. You can still share concerns and seek advice. How consent works and what happens if help is urgent.
If you think they may be experiencing mania or severe depression, seek an urgent specialist mental-health assessment. Contact their team, ask for an urgent GP appointment, or use the urgent help for their UK nation. Do not wait for agreement about a diagnosis. Call 999 if there is immediate danger.[1]
Describe what you have noticed
Bipolar UK says someone experiencing mania may have little insight into how vulnerable or unwell they are. Avoid trying to win an argument about diagnosis. Give one or two observable changes and ask about their priorities.
Find something they want help with
- Contact their existing mental-health team together.
- Ask for a GP appointment about sleep or another concern they accept.
- Use the urgent help for their UK nation if help cannot wait. You can call even if they do not agree to join you.
- Ask whether they will agree to one practical safeguard already discussed in a calmer period.
Give information to services
Contact the existing team, GP or urgent service with specific facts: sleep, spending, driving, threats, unusual beliefs, medication changes, substances and how quickly things have changed. Confidentiality may limit what staff tell you, but it does not prevent them from listening.
Confidentiality: what you can tell the care team and what they may share.
What to avoid saying
- “You're manic. You cannot trust anything you think.” Describe the change you have observed instead.
- “If you refuse help, I'm done with you.” State a genuine boundary without using treatment as punishment.
- “Fine, do whatever you want.” If there is urgent risk, use professional help rather than withdrawing in anger.
Keep your own limits
You cannot provide assessment or treatment yourself. Mind recommends setting boundaries and sharing the caring role where possible.
