Cognitive performance of older women who have survived cancer.

Based on anecdotal reports and a few empirical studies, there is concern about the cognitive effects of cancer and its treatment effects among adults. A cross-sectional comparison of the cognitive performance of 541 elderly women who reported at least one hospitalization for cancer and 3,123 who had no reported hospitalizations for cancer was conducted. The difference between cancer survivors and those with no history of cancer on a screening test of global cognitive functioning was not significant, nor were there differences on a subtest of the global test that assesses verbal memory. Older women who report being hospitalized for cancer as adults may perform similar to women with no history of cancer on rudimentary cognitive tasks.
