Memory aids and work strategies for chemo brain

This page is for people whose thinking or memory has slipped during cancer treatment and who are trying to keep working. It covers why it happens and practical ways to cope on the job.

Losing your thread mid-sentence in a meeting is a particular kind of awful. So is reading the same paragraph four times, or walking into a room with no idea why.

NCI puts the fact of it plainly. It says cancer treatments such as chemotherapy "may cause difficulty with thinking, concentrating, or remembering things." Some types of radiation therapy to the brain can do the same. So can immunotherapy. NCI notes these problems are "sometimes described as a mental fog or chemo brain."

That naming matters more than it sounds. A great many people going through this quietly assume they are becoming unreliable as a person. Knowing there is a recognised name for it changes how you talk about it — to your manager, to your family, and to yourself.

The core of NCI's practical advice is not to try harder. It is to stop relying on recall at all.

NCI suggests: "Write down and keep a list handy of important information. Use a daily planner, recorder, or other electronic device to help you remember important activities."

At work, that principle can turn into a handful of habits. These are our practical suggestions, built on NCI's advice:

• One list, in one place, that everything goes onto. Not three apps and a sticky note.
• Notes taken during meetings rather than after them.
• Confirming decisions in writing, so there is a record neither party has to remember.
• Setting a reminder the moment a task is agreed, rather than at the end of the day.

None of this is clever. That is the point — it has to work on a day when you are not at your sharpest.

Anything important enough to remember is important enough to write down immediately.

NCI's other main suggestion is about shaping the day. It suggests planning your day around your peak energy times, maintaining a routine, and getting adequate sleep.

Most people in treatment have a window when their head is clearest. It might be mid-morning, or it might be after a rest in the afternoon. If you can put the thinking-heavy work in that window and the mechanical work outside it, you get more out of the same day.

Routine helps for a related reason. A task that runs on habit takes less concentration than one you have to reconstruct each time. Same order, same place, same time.

NCI also notes that "Exercise can help to decrease stress and help you to feel more alert," and mentions mind-body practices such as meditation alongside it.

You do not have to describe this as a medical problem to make practical changes. Some ideas that may help, which are our suggestions and not from NCI, are meeting notes, agendas, written follow-ups, a quieter place to concentrate, and tasks scheduled at particular times.

What you disclose, and to whom, is your decision. Ask your care team or a social worker if you want help deciding what to share.

This is the part people most often miss. NCI suggests discussing several things with your care team. These are your risk level, the timing and duration of these problems, steps to prevent them, and warning signs. NCI also suggests asking about available specialists, naming "a neuropsychologist, an occupational therapist, a vocational therapist, and others."

A vocational therapist is specifically concerned with work. An occupational therapist works on the practical strategies of daily tasks. A neuropsychologist can assess thinking and memory in detail. That sometimes helps simply by showing you the shape of the problem.

If nobody has offered a referral, ask whether one would be appropriate. This is one of the areas of cancer care where help exists but is rarely volunteered.
