Some chemotherapy treatments have been linked to problems with memory, learning, and thinking. This particular side effect is often referred to as "chemobrain." Many patients will regain their normal abilities to think and remember after chemo stops, but these side effects may continue in some patients. How chemotherapy causes these problems is not known, but scientists are researching possible treatments to relieve this side effect. Talk to your doctor and care team about your chemo regimen and ask if you should watch for this side effect.

Managing Chemo Brain

There are things you can do to try to reduce the impact of chemobrain on your everyday life:

  • Minimize distractions when you need to complete tasks.
  • Use a daily organizer to help you remember appointments.
  • Record reminders on your answering machine.
  • Make lists of tasks you need to do and cross them off when you complete them.
  • Get plenty of sleep.
  • Let your friends and family know if you are having trouble thinking and remembering. They can help by reminding you of important events and appointments.

Your problems with memory and concentration may improve once you complete your chemotherapy treatment. However, for some patients, chemobrain can continue for years after treatment has stopped. Knowing which patients will have ongoing difficulties is hard to predict, since the way chemotherapy causes these problems is not well understood.

Ask Your Doctor:

  • What are my chances for experiencing chemobrain?
  • What should I do if I experience problems with forgetting and concentrating?
