Forgetfulness, Confusion and Disorientation -- Symptoms of Chemobrain

Comments (2)

Most cancer patients who undergo chemotherapy mentally prepare themselves for the side effects of chemotherapy: fatigue, nausea, mouth sores and hair loss. However, many are not ready for problems in concentration and memory -- the forgetfulness, confusion and disorientation that affect some people undergoing chemotherapy treatment. This condition has been dubbed "chemobrain" or "chemofog." 

Chemobrain is an important issue for cancer patients because cognitive problems can have a negative impact on their ability to work or complete everyday tasks, and memory issues have a negative effect on quality of life in general. While cancer survivors have talked about these cognition problems for years in their support groups, the medical field had not given it much credence -- until recently, that is. 

Research carried out over the past few years has involved cognitive testing, laboratory studies and brain imaging of patients undergoing chemotherapy. In a study in the journal Cancer, researchers from the National Cancer Center Hospital East in Chiba, Japan, noted that the shrinking of brain structures due to chemotherapy might be a cause of the memory complaints. 

If you are a cancer patient and you have memory complaints, don't immediately suspect your chemotherapy. There could be other causes at work. Underlying medical issues, such as anemia or hypothyroidism, can cause cognitive deficits, and so can depression and poor sleep, with its accompanying daytime fatigue. Certain medications can also cause cognition problems. 

If you are undergoing any type of cancer treatment or have just finished up your chemotherapy sessions, be sure to tell your doctor any problems you've observed with your memory or your ability to concentrate. 

Although we still don't know definitively what causes cancer-associated cognitive changes and whether these changes will be temporary or permanent, one way to limit any mental confusion you may be experiencing is to stick to a routine, with written schedules and reminders to track appointments, activities and important dates. Using Post-It notes and placing them around the home and workplace is also a great way to create daily visuals to keep you focused.

I was diagnosed with non Hodgkins Lymphoma a few years ago. I went thru a series of chemo and maintenance for about 2 1/2 years. I am now in remission. However, during that period I developed "chemo brain". I was fired from my Business Analyst-Supply Chain, Logistics position because I could not keep up with my work.

I am now on disability and my family life has been on the decline because I "don't pay attention to my wife and kids" so they ignore me and leave me out of a lot of their activities.

Is there anything I can do to improve my memory and get back into my family life?

It has been 27 months since my last chemo treatment, and I still have major memory problems. For example, this week I was eating lunch with my friends in a small cafeteria. I got up to refill my drink. I turned and and couldn't remember where we were sitting. I felt a sudden sense of panic. Then I saw my friends. This type of memory lapse happens often.
