What is chemo brain?
During chemotherapy treatment, you may experience different side effects.
These can vary depending on the type of cancer you have and the stage of your cancer. However, a common side effect that you may have heard of is chemo brain.
Chemo brain or chemo fog is a term used to describe thinking and memory problems which may occur during or after chemotherapy treatment. The medical term for chemo brain is cancer-related-cognitive-impairment (CRCI).
What causes chemo brain?
The exact cause of chemo brain is not fully known. However, research suggests that it is not just the direct effect of the chemotherapy medication itself causing chemo brain.
It is thought that other factors such as anxiety, depression and sleep problems may also contribute to chemo brain.
Other possible causes are:
The cancer itself
Chronic stress affecting the part of the brain responsible for learning and memory
Genetic factors
How does chemo brain affect cancer patients?
Chemo brain may impact you in different ways, and can affect:
the working memory, for example forgetting names and having difficulty following directions
verbal memory, for example feeling that they are unable to keep up with a conversation
processing speed, for example having difficulty learning new skills and problem solving
Cancer patients who experience chemo brain may have trouble remembering, learning new things, concentrating, or making decisions affecting everyday life, such as:
having difficulty concentrating
being forgetful
having problems making decisions
having problems multi-tasking
taking longer to finish things
having trouble remembering common words
having problems learning new things
Coping with chemo brain
While chemo brain is a common problem, remember that it is likely to improve with time.
Stress and tiredness can contribute to memory and concentration problems, so try to get plenty of rest and do regular relaxation techniques and activities (including exercise).
Be open with your friends and loved ones about your chemo brain symptoms and let them know how they can support you during this time.
