Relationship of fatigue with cognitive performance in women with early‐stage breast cancer over 2 years

Fatigue and cognitive dysfunction are major concerns for women with early‐stage breast cancer during treatment and into survivorship. However, interrelationships of these phenomena and their temporal patterns over time are not well documented, thus limiting the strategies for symptom management interventions. In this study, changes in fatigue across treatment phases and the relationship among fatigue severity and its functional impact with objective cognitive performance were examined.
