A substantial proportion of breast cancer survivors report significant, long-lasting impairments in cognitive function, often referred to as "chemobrain." Advances in detection and treatment mean that many more patients are surviving long-term following diagnosis of invasive breast cancer. Thus, it is important to define the types, extent, and persistence of cognitive impairments following treatment with cytotoxic cancer drugs. ⋯ Our results show that chronic treatment with either of two commonly used chemotherapeutic agents impairs cognitive ability and suggest that strategies to prevent or repair disrupted hippocampal neurogenesis may be effective in ameliorating this serious side effect in cancer survivors.
