These results suggest that having a breast cancer diagnosis may be associated with cognitive impairment. While chemotherapy may have a negative impact on cognitive function, chemotherapy-related impairments appear to be more acute than chronic side effects of therapy. Further studies are needed to provide insight into the clinical significance and potential mechanisms of cancer and treatment-related cognitive impairments.
The ability to identify high-risk patients has important implications for practice in regard to informed consent, patient education about the effects of treatment, and preventive strategies.
Cancer- and cancer treatment-related cognitive impairment is a common, bothersome, and potentially debilitating symptom incurred by cancer survivors. Cognitive impairment has a significant impact on patients' day-to-day functioning and quality of life, but it remains under-recognized and undertreated. This article, which is an update from the initial Oncology Nursing Society Putting Evidence Into Practice for cancer- and cancer treatment-related cognitive impairment, provides a comprehensive critical review and summary of the evidence regarding interventions addressing cognitive impairment for cancer survivors. This article examines the effectiveness of interventions focused on cancer- and cancer treatment-related cognitive impairment, makes recommendations for practice, and identifies gaps in knowledge and areas for further research.
The potential for chemotherapy-induced impairments in cognitive function may influence patients' ability to give informed consent, identify treatment toxicities, learn self-care measures, and perform self-care behaviors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
