Prevent, Minimize, Heal Chemo brain

Share Button

“This is the first study that puts chemo brain on a sound scientific footing, in terms of neurobiology and cellular biology.”

After years of denials, excuses and stalling from conventional oncology over the existance of a side effect called chemotherapy-induced cognitve dysfuntion aka chemo brain, the article linked and excerpted below conclusively establishes  that chemotherapy can cause long-term brain damage.

I found the main article below to be pretty dense. But the key concepts, as far as this chemo brain survivor is concerned, is that the chemo drugs kill a type of cell called oligodendrocytesthis cell is central to the health of “myelin sheaths-” myelin sheaths act like a sort of insulation wrapped around an electric wire. If the oligodendrocytes are damaged or destroyed, the myelin sheath deteriorates and nerve impulses necessary for the transfer of information (the process of thinking…) disintegrates.

The challenge of the newly diagnosed cancer patient is that he or she probably will not make decisions about his/her therapy plan based on the fear of side effects like chemo brain. However, as a long-term chemo brain surivor myself, I think that chemo brain can be either prevented, minimized or even healed.

If you have been recently diagnosed with cancer but have not yet had any treatment, consider a sort of “prehabilitation.” In addition to getting in shape to undergo the rigors of surgery, chemo and or radiation, consider supplementation discussed below, that may reduce your risk of chemo brain. By increasing your blood levels of vitamin D3 and/or omega-3 fatty acids, according to the articles linked below, you may support the health of your myelin sheaths.

If you have recently undergone one or more of the chemotherapy regimens listed in the article below, as being toxic to oligodendrocytes, by beginning a sort of chemo brain healing lifestyle through brain games and exercise and nutritional supplementation, you may be able to reduce the damage done to your brain by chemotherapy.

I supplement with vit. D3, Omega-3’s, I have signed up with Posit Science to send me brain games each day and I exercise daily-I exercise modestly but frequently. I wouldn’t say that chemobrain has healed completely but my brain functions a LOT better today in 2019 than it did in 1999.

If you are like me, you underwent aggressive chemotherapy years ago and you have been living with a variety of chemo brain symptoms for years. At this stage all I can do is offer my own experience in hopes of healing your brain damage as best you can.

The bad news is that your body has undergone lots of toxicity and sustained a great deal of organ damage (including your brain). The good news is that the therapies shown to heal your brain function also may heal other organs. For examply vitamin D supplementation has also been shown to enhance bone health. Further, we’ve established that brain games and exercise help not only chemo brain but can help to reduce your risk of dementia a well as other chronic diseases.

After almost 25 years living with an “incurable cancer” as well as a living with a host of long-term and late stage side effects I’ve made peace with the idea that cancer patients and survivors may need to undergo toxic chemotherapy regimens- all that can cause real damage. However having read this post, you may come to the conclusion that toxic regimens must be minimized. Further, coupling less toxicity with lifestyle therapies such as nutritional supplementation, you may be able to minimize the damage done to your body by the very toxic therapies that are designed to cure your cancer.

Have you been diagnosed with cancer? What type, what stage? Are you considering chemotherapy? Please scroll down the page, post a question or comment and I will reply to you ASAP.

Thank you,

Common Cancer Treatments Toxic to Healthy Brain Cells

Common drugs used to treat cancer may be more harmful to healthy brain cells than the cancer cells that they are intended to destroy. That is the conclusion of a study conducted by researchers at the University of Rochester Medical Center and published today in the Journal of Biology. The results, which also indicate that chemotherapy may cause long-term brain damage, represent the closest that scientists have come to pinpointing the underlying physiological cause of “chemo brain,” a common side effect of cancer treatment that scientists are only now beginning to comprehend

Cancer patients who receive chemotherapy have long complained of adverse neurological side effects ranging from memory loss to, in extreme cases, seizures, vision loss and even dementia.  Until very recently, these conditions were often dismissed as unrelated to the cancer treatment and rather the result of the patient’s mental state. However, a growing body of evidence has documented the scope and cognitive impact of chemo brain. A study earlier this year conducted by the James P. Wilmot Cancer Center at the University of Rochestersuggested that upwards of 82% of cancer patients reported that they suffer from some form of cognitive impairment…

As in other organs and systems in the body, the central nervous system is populated with several types of cells that serve the function of producing or repairing the cells needed for normal function. These cells fall into three general categories: dividing stem cells, dividing intermediate cells types called precursors and progenitors, and non-dividing mature cells.

Noble and his team exposed several different populations of healthy brain cells as well as multiple human cancer cell lines to clinically relevant levels of three commonly used chemotherapy drugs – carmustine, cisplatin, and cytosine arabinoside. These drugs are used to treat a wide range of cancers, including certain types of breast cancer, lung cancer, colon cancer, leukemia, Hodgkin and non-Hodgkin lymphomas, and, in the case of carmustine, brain tumors...

Notably, these drugs were toxic to both non-dividing cells and dividing stem cells, precursors, and progenitors even at very low concentrations. Destruction of dividing cells was not altogether unexpected, as that is what these drugs are designed to target.  However, the loss of dividing cells has onerous consequences as these populations are responsible for replenishing the other cell types in the central nervous system

Noble also points to the destruction of a specific cell type that plays a critical supporting role in the central nervous system. These cells, called oligodendrocytes, are responsible for producing myelin, the fatty substance that, like insulation wrapped around a wire, covers nearly all the large nerve cells processes – called axons – in our bodies and helps signals in the nervous system move crisply and rapidly from one point to another.

Myelin membranes are very dynamic and are always being turned over and renewed. However, if you kill the oligodendrocyte cell then myelin membrane eventually disintegrates…”

Because everything in the nervous system is based upon precise timing of information transfer, this destruction of the insulation necessary in normal impulse transmission has significant neurological ramifications

Noble and his team are quick to point out that no one should avoid cancer treatment because of these results and that chemotherapy will remain a cornerstone of cancer therapy for the foreseeable future. Instead, they believe that the opportunity for the scientific community is to use this knowledge to develop ways to protect the brain’s cells from these drugs…”

Supplement for myelin regeneration

“Low vitamin D levels have been linked to the onset of multiple sclerosis, and the researchers’ findings suggest that the vitamin might also affect disease progression by controlling myelin sheath regeneration, a critical step to alleviate the disease’s symptoms that fails as patients age…”

Long-Chain Omega-3 Fatty Acids Supplementation Accelerates Nerve Regeneration and Prevents Neuropathic Pain Behavior in Mice

“These results point to the regenerative and possibly protective properties of a combined EPA and DHA oral administration after peripheral nerve injury, as well as its anti-neuroinflammatory activity, evidencing ω-3 PUFAs promising therapeutic outcomes for NP treatment…”
