Treatment Options & Coping Strategies

There are a number of possible treatment options or coping strategies patients can use to help deal with chemo brain. Medications and herbs have been studied as possible treatments for chemo brain. There is no strong evidence to suggest that these are beneficial to patients or that they are proven treatments that help overcome chemo brain.

Strategies that have shown to have some benefit in helping to patients to improve concentration and decision-making and other effects of chemo brain during cancer treatment include:

Brain and memory training

Regularly exercising your brain can help manage chemo brain symptoms. Doing activities like puzzles, brain games and problem-solving quizzes, learning new hobbies, or playing musical instruments can use and activate the brain in different ways. Activating and using the brain can improve short-term memory and can support good mental health.

If chemo brain is making you feel confused, try using memory aides such as checklists, calendars and smartphone apps to keep track of your appointments or daily tasks. Sticking to a daily routine can help to lower the number of decisions you need to make, and help you feel in better control.

Exercise

Engaging in everyday physical activity may improve cognitive function. Physical activity can be many things and will depend on how you feel. Consider small amounts of light exercise each day. Activities such as walking or gentle yoga are ideal.

Mind and body

Techniques like meditation, deep breathing, and mindfulness can lower anxiety or a racing mind, and improve focus. You may also find you can manage worry and stress through relaxation techniques like acupuncture or yoga.

Sleep and rest

Try and prioritise rest. A lack of rest or sleep can cause you to feel tired and intensify your ability to have trouble focusing, remembering, thinking and making decisions. Short naps or breaks during the day can refresh your mind and combat fatigue.

Healthy lifestyle choices

Enjoying a healthy lifestyle has many benefits. Aim to eat a balanced diet with foods that give you energy and nutrients, look for foods rich in antioxidants, vitamins, and omega-3 fatty acids. Drinking water and staying hydrated will support overall brain health. Try to limit or cut out alcohol, caffeine and smoking.

Cognitive Behavioural Therapy (CBT)

CBT is a therapeutic approach that helps individuals to identify and modify thought patterns and behaviours, particularly negative ones. CBT provides practical strategies to help patients better cope with memory challenges, reduce worry and fear, and improve cognitive function. It is done through therapy with a qualified allied health professional. Psychologists, occupational therapists, psychiatrists, counsellors or mental health nurses may be able to support you through regular therapy. If chemo brain disrupts your daily life, consider seeking help from allied health professionals.

Is there hope for treatment in the future?

Researchers at the Massachusetts Institute of Technology (MIT) have made promising discoveries in supporting people with chemo brain symptoms. They’ve explored a non-invasive treatment that stimulates gamma frequency brain waves.

The treatment involves daily exposure to light and sound with a frequency of 40 hertz. It aims to stimulate gamma oscillations in the brain, which play a crucial role in attention, perception, and memory.

This new approach could reduce chemo brain symptoms and potentially benefit people with various neurological disorders. Researchers continue to explore and refine this treatment to enhance its effectiveness in clinical settings and daily life.
