Chemo brain, often referred to as chemo fog, cancer-related cognitive impairment, or cognitive dysfunction, describes the thinking and memory issues experienced by many cancer survivors during and after treatment. While the exact causes of chemo brain are not fully understood, it is recognized as a real and challenging side effect. Studies suggest it affects more than half of all cancer survivors, and up to 75% of those who received chemotherapy as part of their treatment.
Common symptoms of chemo brain include:
- Trouble remembering names, dates, and events.
- Problems with planning and decision-making.
- Memory lapses, like forgetting familiar information.
- Struggling to find the right words during conversations.
- Difficulty concentrating and a short attention span.
- Difficulty multitasking, such as managing two tasks at once.
- Slower learning and task completion.
Cancer-Related Causes:
- The stress of a cancer diagnosis, leading to anxiety and depression, can impact memory.
- Some cancers produce chemicals that affect brain function.
- Genetic predisposition to chemo brain
Medications for cancer symptoms, such as painkillers
- Other medical conditions like diabetes, thyroid issues, depression, anxiety, and nutritional deficiencies
- Cancers in or spreading to the brain can directly cause cognitive changes.
- Cancer Treatments can impact cause chemo brain, such as:
- Bone marrow transplants;
- Chemotherapy;
- Hormone therapy;
- Immunotherapy;
- Radiation therapy;
- Surgery;
- Targeted drug therapy;
Complications from Cancer Treatment:
- Anemia
- Fatigue
- Infections
- Menopausal symptoms or hormonal changes
- Sleep problems
- Pain from treatments
The intensity and length of chemo brain symptoms can vary greatly from one person to another. While many cancer survivors are able to return to work, some may need more time and effort to complete tasks. If you are struggling with significant memory or concentration issues that affect your job performance, it's important to speak with your doctor. They might refer you to an occupational therapist or a neuropsychologist, who can assist in adapting your current job or finding new opportunities that match your strengths.
In rare instances, severe cognitive difficulties may prevent people from working. If this happens, you might consider applying for disability benefits. Your healthcare team can connect you with an oncology social worker or a similar professional to explore your options.
“Remember, it’s normal to experience cognitive changes during and after cancer treatment, but with patience, self-care, and the implementation of practical strategies, you can support your brain health and navigate through the fog to a clearer, sharper mind.”
