In a recent article published by Cancer Network (Journal of Oncology digital platform) some of the causes of chemo brain were explored. The American Cancer Society describes chemo brain as a decrease in mental “sharpness” before, during, and after cancer treatment. Many things have been shown to contribute to chemo brain – including cancer itself, chemotherapy, medications used for nausea and pain, hormone treatments, and surgery. Even stress, fatigue, anxiety and depression, and sleep disturbance have been implicated in the cause of chemo brain.
There has also unfortunately been some small studies, including a twin study comparing twins “in which one sibling had cancer while the other did not. When compared with their cancer-free twins, cancer patients were shown to be more likely to experience cognitive dysfunction and dementia. Despite the lack of statistical significance in the odds ratio, there was a two-fold increase in dementia in the cancer survivor group vs the cancer-free twin group.”
There are no currently approved treatments for chemo brain, and the medications that have been proposed are the same as those used for ADHD and Alzheimer’s disease, which are called psychostimulants. In a study titled Psychostimulants for cancer-related cognitive impairment in adult cancer survivors: a systematic review and meta-analysis that was published June 28, 2019, in the Journal Supportive Care in Cancer they concluded that of 6 studies reviewed, 3 showed cognitive improvement and none demonstrated increased quality of life. Fortunately, when we review the factors that contribute to chemo brain there are many natural treatments that have shown great benefit in managing these conditions.
Exercise has been shown to improve sleep and cognition in patients, as well as mood and chemotherapy side effects. Mindfulness-based stress reduction has also shown to improve mood and sleep. In addition to advice about these interventions, there are many supplements and intravenous nutrients that impact the many causes of chemo brain.
Many patients are overwhelmed by the number of pills they need to take, especially when treatment-related nausea is a factor, so the option of doing intravenous treatments is frequently requested. Some intravenous therapies that have shown improvements in cognition include repleting deficient vitamins and minerals as well as nutrients such as:
