There's no clear definition of chemo brain, so no tests exist to diagnose this condition. Cancer survivors who experience these symptoms often score in normal ranges on memory tests.

Your doctor may recommend blood tests, brain scans or other tests to rule out other causes of memory problems. But if no apparent cause can be found for your symptoms, your doctor may refer you to a specialist who can help you cope with memory changes.
