Numbers can be especially high-stakes when aphasia affects reading, speaking or writing: the safest approach is to slow the task down, show the number visually, confirm it in a second way and use another person or professional for important decisions.
Why numbers deserve a separate strategy
A person with aphasia may be comfortable discussing a familiar topic but still struggle when a conversation suddenly depends on a date, amount, postcode, telephone number or dosage instruction. A small error can have a large consequence, so number-heavy tasks deserve a deliberate checking system.
The goal is not to test the person. It is to make the information visible and verifiable. Spoken information disappears quickly; written numbers remain on the page. A calendar, calculator, printed bill, appointment card or labelled photo can reduce the amount that must be held in working memory.
More everyday communication resources can be explored through Aphasia Guide. The same supported-communication principle applies here: preserve independence while adding enough structure to keep important information accurate.
Money and prices
When shopping, paying bills or reviewing a bank statement, isolate one amount at a time. Point to the figure while saying it. If £37.50 matters, show “£37.50” rather than relying only on “thirty-seven pounds fifty”. For a large purchase, write the total, deposit, monthly payment and final cost on separate lines.
A calculator can be a communication tool as well as a maths tool. The person can type an amount, show it to someone else and confirm the same number visually. For bills, highlight the amount due and due date in different parts of the page rather than expecting a reader to navigate every paragraph.
Financial decisions should not be rushed because speech is difficult. If a contract, transfer or purchase is important, use a trusted supporter or financial professional to verify the figures without replacing the person’s right to make their own decisions where they have capacity to do so.
Dates and appointments
Dates are easier when they are anchored to a real calendar. Instead of asking, “Is Tuesday the 14th okay?”, open the calendar, point to the date and add the appointment in front of the person. Include the place and purpose, not just the time.
Use one consistent date format. Switching between 04/09/2026, September 4 and 9/4 creates unnecessary opportunities for confusion. For travel or appointments, write the day of the week as well: “Friday 4 September, 10:30”.
Set one reminder the day before and another with enough time to prepare. Too many alarms can become background noise; a small number of meaningful reminders is usually easier to act on.
Phone numbers, PINs and verification codes
Long strings of digits are difficult to retain even without aphasia. Break phone numbers into familiar groups and place spaces between them. When confirming a number, compare each group from left to right rather than reading the whole number repeatedly.
One-time security codes should be treated carefully. A legitimate bank or service may ask a user to enter a code into its own app or website, but unexpected callers who request a security code can be a fraud risk. If there is doubt, end the call and contact the organisation through a trusted number.
For passwords, PINs and private codes, communication support must also protect privacy. A supporter should not create a permanent list of sensitive credentials in an insecure notebook or shared chat simply because speaking them is difficult.
Medication labels and dosage instructions
Medication information is not a place to guess. Keep the original pharmacy label with the medicine. If reading is difficult, ask the pharmacist or prescribing clinician for accessible instructions and review them with a trusted person.
A simple chart can show the medicine name, a photo of the package, the time of day and the exact instruction copied from the approved label. Do not change a dose, tablet schedule or method of taking a medicine based on a general aphasia communication guide.
If the person cannot confidently match the written instruction to the correct medicine, ask a pharmacist, nurse, doctor or other qualified professional for a safer system. This is a communication-support issue and a medication-safety issue at the same time.
Build a personal number toolkit
- A large-print calendar with appointments written in a consistent format.
- A calculator for showing and checking amounts.
- A small whiteboard or notepad for writing one number at a time.
- A contact card with important non-secret phone numbers.
- A labelled folder for bills, appointment letters and official documents.
- A rule that important money, medication and legal figures receive a second check.
Numbers do not have to become a daily test. With visual support and a reliable checking routine, many number-heavy tasks become calmer and more manageable. A speech-language pathologist can help adapt these strategies to the person’s reading, writing and communication strengths.

FAQ
Should someone with aphasia stop handling money?
Aphasia alone does not determine financial decision-making ability. Communication support may make a major difference. High-stakes decisions should be handled with appropriate professional and legal safeguards when needed.
Is writing a number always easier than saying it?
Not for everyone. Some people find written numbers easier; others may have difficulty reading or writing them. Test several formats and use the one that is most reliable.
Can a family member rewrite a medication label?
It is safer to keep the original pharmacy label and ask a pharmacist or clinician for accessible instructions rather than creating an unofficial replacement that could introduce an error.
