Q. I have been receiving chemotherapy treatments for the past six months and my memory is not as good as it used to be. Is this because of the chemo?


During chemotherapy treatments, you may notice memory or thinking changes, sometimes referred to as chemobrain. Chemobrain affects your cognitive or thinking abilities including: memory, attention, concentration, word finding or retrieval, multi-tasking, learning, and sense of direction. Researchers are not certain of the exact causes of these difficulties, but they are currently studying this problem in order to find ways to both treat and prevent it.

There are a number of treatable conditions that can affect memory, such as low blood counts, hormonal changes, stress, fatigue, sleep disturbances, depression, and anxiety. Some of your medications could also be affecting your ability to think clearly.

It is important for you to talk with your doctor if you are having trouble with your memory. Your health care team can be very helpful to you in figuring out ways to manage your memory and thinking changes related to chemotherapy. Bring a list of your questions to your doctor, take notes, and ask permission to record your visit. If possible, bring someone with you. Get a second opinion if your doctor doesn’t take your concerns seriously.

Memory tools can help to boost your memory. Write things down in a planner, pick one spot to keep your keys and wallet, place reminders around your home and work space of tasks you need to do, and recognize the importance of nutrition, exercise and sleep.
