Chemo brain is a common term used by cancer survivors to describe thinking and memory problems that can occur after cancer treatment. These memory problems can be a frustrating and debilitating side effect of cancer and its treatment. The causes are not always associated with a chemo treatment and may be due to certain cancers producing chemicals that affect memory as well as the stress associated with a cancer diagnosis.
Symptoms include being unusually disorganized, confusion, fatigue, short attention span, trouble with verbal and visual memory, and difficulties in concentrating, finding the right word, learning new skills, and multitasking.
