People undergoing chemotherapy become intimately familiar with the term “chemo brain,” as that feeling of cloudiness and mental fog that so often comes during and after treatment. Doctors and other medical professionals call it “post-chemo cognitive impairment” or “cancer-related cognitive change.”
This perceived impairment in thinking, learning, and problem-solving can be caused by the chemotherapy drugs, cancer or other disease being treated, secondary medical conditions like hypertension, or even anxiety about the condition or treatment.
The chemotherapy medications most likely to cause chemo brain include Cytoxan (cyclophosphamide), Adriamycin (doxorubicin), Adrucil (5-FU), and Taxol (paclitaxel).
Some of the symptoms of chemo brain include:
If you’re having difficulty with negative changes to your cognitive functioning, be sure and mention it to your oncologist or primary care physician to ensure your future brain health. They may recommend you see a neuropsychologist.
According to the experts at M.D. Anderson, “Symptoms of chemo brain can fade after chemotherapy ends, but each patient is different. Some may take a year or more after treatment to feel normal again; others may never regain their full mental ability.
There are several ways to improve cognitive function during and after chemotherapy treatment, including non-medical and medical options. After you’ve discussed your symptoms with your doctor, these coping strategies might be helpful, too.
If you’re feeling anxiety or depression, do what you can to reduce your stress levels and add relaxing rituals to your day, like a long soak in the bath or a 20-minute meditation. If your feelings seem unmanageable, seek immediate help from your PCP or oncologist.
Know, too, that a diagnosis of cancer or any other serious illness can cause “medical PTSD,” which is often treatable with talk therapy and/or medication. PTSD brings its own set of symptoms, though some may mimic chemo brain.
While some people stop experiencing chemo brain immediately after treatment, other patients experience it for months or even years. So what can you do if you’re one of the “lucky few” with lingering brain fog after chemotherapy? After you’ve discussed it with your doctor, consider that many experts recommend supporting brain health through nutritional supplementation.
