When cancer patients begin chemotherapy, most anticipate some side effects: fatigue, nausea, hair loss. But nearly three-quarters of them will experience a lesser known side effect: a kind of mental fog that happens during and after treatment, dubbed chemo-brain.

A patient who had been able to juggle many things in her head suddenly might be unable to remember her own phone number, keep track of her appointments, or recall her assistant’s first name, at least not without a lot more effort. For some patients, these symptoms persist for months and even years after treatment.
