What Is Chemo Fog?

Chemo fog, also called chemo brain, refers to memory and cognitive problems some cancer patients experience after treatment. The condition is not fully understood, according to the Mayo Clinic, which says more research is needed.

  1. Symptoms

    • Symptoms of chemo fog include confusion, tiredness, lack of focus, disorganization, trouble learning new skills and multitasking, having a hard time in conversation and with everyday tasks, and short-term forgetfulness and other memory problems.

    Time Frame

    • Though there is no cure for chemo fog, in most cases it is temporary. For most patients, the signs fade within two years, says the Mayo Clinic.

    Significance

    • In addition to causing everyday frustrations, chemo fog has such a serious effect on some patients that they are unable to return to work. Occupational therapy may help them develop new abilities and find a different job.

    Theories/Speculation

    • No one is sure exactly what causes chemo fog, but medical professionals speculate that factors may include the cancer treatments themselves; conditions related to the treatment, such as poor nutrition or anemia; depression or stress; and genetics.

    Solution

    • Chemo fog has no specific treatment, but doctors may prescribe medications intended to treat Alzheimer's, ADHD or sleep disorders. Other strategies include exercising the brain with crossword puzzles and games, and developing new ways to accomplish tasks.
