Diagnosis and treatment
The first days after a diagnosis
You may have a name for what has been happening and still have many questions. These suggestions are for the first day or two after an adult’s diagnosis, whenever you are ready to use them.
Get the next few days clear
You do not need to become an expert tonight. If they want your help, write down the next appointment, who to contact with questions and any instructions the team has given. Check what they need for the journey home, food, sleep or time away from work.
Ask the clinician to explain the diagnosis in ordinary language and put the main points in writing. Useful questions include: “How certain is this?”, “What happens next?” and “Who do we call if things change before the next appointment?”[1]
What do you need to work out?
What does the diagnosis mean?
A diagnosis can help describe someone’s difficulties and guide treatment. It does not describe everything about them or predict exactly what their life will be like. Sometimes the diagnosis changes as clinicians learn more.
They might feel relieved, frightened, angry or unconvinced. Ask what the explanation means to them before offering your own. If it does not fit their experience, help them write down what they want the team to reconsider.[2]
What should I read first?
Start with the written information from their team and the guide for their condition. Those guides link to NHS and specialist sources. Write down questions that apply to this person rather than trying to absorb every possible symptom or treatment.
Someone else’s worst experience online is not a forecast. If searching is making you more frightened, stop for now and take the question to the next appointment. You can return to research updates when you want more detail.
Who should we tell?
Ask who they want to know and how much to say. A relative helping with meals may only need to know that things are difficult this week. You do not have to send a full medical explanation to the whole family.
You could say: “Who would you like me to update? Is there anything you want kept between us?” Our information-sharing template helps record their preferences for the care team. For children or relatives at home, see living together when someone is unwell.
What should we ask about treatment?
With their agreement, help make a short list: what each treatment is for, likely benefits and unwanted effects, alternatives, and when the plan will be reviewed. If medicines have been prescribed, ask which changes need a prompt call and whom to contact.
Medicines for supporters covers practical help and concerns to raise. Use the meeting-notes tool to keep questions and agreed actions together.
I am struggling to take it in
Choose one manageable job rather than promising to handle everything. Ask another trusted person for a specific piece of help, such as a meal or a lift. You can seek support for yourself without sharing every detail of their care.
If you are already carrying too much, see when you are running on empty. If their condition is getting worse and help cannot wait, use urgent help.

- Questions and written information
NHS: mental-health assessments covers explanations, questions, taking someone with you and reviewing care. The first-days checklist and suggested wording are ours; 48 hours is not a clinical deadline.
Back to the advice - What a diagnosis can and cannot tell you
Mind: diagnosis explains its purpose, limitations, possible changes and different reactions. The reading and family-update suggestions apply those ideas to a supporter’s first few days.
