Abstract

Purpose/Objectives: To develop a conceptual model of chemotherapy-related changes in cognitive function. Data Sources: MEDLINE®, CINAHL®, HealthStar, and PsycINFO®, databases. Data Synthesis: Patients undergoing chemotherapy often complain of forgetfulness, absentmindedness, and an inability to focus when performing a variety of daily tasks. Changes in cognitive function have been referred to by the colloquial term "chemo-brain." The authors conducted an examination of the literature to investigate relationships among concepts and to synthesize current knowledge. Conclusions: Cognitive function, defined as higher-order mental processes, may be altered along two distinct and interacting pathways: (a) the cancer diagnosis, which can lead to anxiety, stress, distress, and depression: and (b) the direct physiologic effects of cancer treatment. The Chemotherapy-Related Change in Cognitive Function conceptual model is informed by a review of literature that illustrates antecedents, moderators, mediators, and consequences that may be relevant to this issue. Implications for Nursing: When a patient presents with cognitive complaints, the problems can be evaluated for intervention when an overall understanding exists of chemotherapy-related cognitive changes based on a conceptual model that continues to be informed through well-conceptualized and well-designed research.
