Cancer and its treatments cause a variety of side effects, some of which people recover from quickly, while others last long after treatment is over. After chemotherapy, around 70% of cancer survivors report difficulties with memory and concentration – this is colloquially known as “chemo brain”.

Studies that evaluate cancer patients over time (longitudinal studies) have shown that about 20% to 30% have cognitive problems, whereas we would expect about 10% impairment in healthy people.
