Care During Chemotherapy and Beyond

Chemo Brain

What is Chemo Brain?

The phrase "chemo brain" has come to be used by cancer survivors to describe changes in memory, attention, concentration, and abilities to perform various mental tasks that are associated with receiving chemotherapy treatments for cancer.    

In medical jargon the effects of chemo brain are referred to as cognitive deficits or declining neuropsychological functioning. In recent years more focus has been placed on this phenomena as a side effect of chemotherapy. 

Other Factors Contributing to the "Chemo Brain" Effect:

  • Aging
  • Depression
  • Menopause
  • Low blood counts
  • Medications
  • Emotional upheaval of cancer.

An example of the increasing interest in "chemo brain" in the research community is the published results of a study in the January 15, 2002 issue of The Journal of Clinical Oncology. The study looked at the neuropsychologic impact of standard-dose chemotherapy in long-term survivors of breast cancer and lymphoma. The findings of this study showed that chemotherapy could be associated with cognitive deficits or "chemo brain," in some patients. These "chemo brain" deficits were found to be subtle, and that survival benefit of chemotherapy far outweighs the potential risks to memory or concentration for most patients.

Now that "chemo brain" is being recognized and focused on, some of the directions of study are attempting to determine which chemotherapies are more prone to contributing to chemo brain.  Researchers are also looking at developing ways of preventing chemo brain from happening or strategies to help survivors who continue to experience thinking problems.
