By Mayo Clinic staffChemo brain is a common term used by cancer survivors to describe thinking and memory problems that can occur after cancer treatment. Chemo brain can also be called chemo fog, cognitive changes or cognitive dysfunction.
Though chemo brain is a widely used term, it's misleading. It's not yet clear that chemotherapy is the cause of concentration and memory problems in cancer survivors. And many cancer survivors with memory problems still score well on cognitive tests, leaving doctors wondering whether chemo brain really exists.
Despite the many questions, it's clear that the memory problems commonly called chemo brain can be a frustrating and debilitating side effect of cancer and its treatment. More study is needed to understand this condition.
