Another Side Effect Of Chemotherapy: 'Chemo Brain'

It's well-known that chemotherapy often comes with side effects like fatigue, hair loss and extreme nausea. What's less well-known is how the cancer treatment affects crucial brain functions, like speech and cognition.

For Yolanda Hunter, a 41-year-old hospice nurse, mother of three and breast cancer patient, these cognitive side effects of chemotherapy were hard to miss. "I could think of words I wanted to say," Hunter says. "I knew what I wanted to say. ... There was a disconnect from my brain to my mouth."

Before getting treated for cancer, Hunter led a busy, active lifestyle. But the effects of chemotherapy on her brain made it difficult for her to do even the most basic things.
