We've all had days where we don't feel like ourselves – where we feel a little 'out of our mind'. Perhaps we can't seem to think fast enough, can't remember names, or have a difficult time multitasking. Imagine feeling like that every single day – all while having to battle the challenges of cancer treatment and recovery.
This condition, known as "chemo brain", is what many cancer patients undergoing chemotherapy have to go through.
"Chemo brain" is a term often associated with thinking and memory problems a cancer patient may have during their cancer treatment journey.
It is also called cancer-related cognitive impairment. Patients suffering from "chemo brain" have a decrease in their cognitive functions, causing an overall decrease in mental sharpness.
Aside from this, other symptoms include:
However, other treatments such as hormone therapy and radiation may also cause "chemo brain". Some patients are more susceptible to cancer-related cognitive impairment than others, and this may be due to two main factors.
Firstly – the type of cancer the person has. If a patient's cancer metastasises (spreads) to their brains, causing a brain tumour, their likelihood of getting "chemo brain" would increase.
Secondly – the type of drugs used during chemotherapy. Steroids and certain types of pain medications may also increase the chance of experiencing "chemo brain". Other risk factors include:
For the majority of patients who complete chemotherapy, "chemo brain" improves within 9 – 12 months.
In extreme cases, "chemo brain" can last for more than a year, although this only happens to 10 – 20% of patients. A smaller percentage of patients in this group may also experience noticeable symptoms a decade after undergoing chemotherapy, although symptoms should have reached a plateau and not be worsening at this point.
"Chemo brain" may be managed in the following ways:
Other practical steps include:
Speak to your oncologist about what you're going through, as they will be able to recommend the best course of action to help you manage your condition.
Sometimes, your family members or caregivers may not fully understand "chemo brain" or how to manage its symptoms. Don't be afraid to reach out to your oncologist, counsellor or physiatrist if you need help. With a strong support system, "chemo brain" is a condition that can be managed or even overcome with time.
