##Daily Cognitive Functioning Among Cancer Survivors ###Cognitive performance of breast cancer survivors in daily life: Role of fatigue and depressed mood **PIs: **Stacey Scott, Brent Small **Description: ** Considerable interest exists in long-term treatment effects in cancer survivors that can have a significant impact on quality-of-life (QOL) outcomes. Cognitive impairment is one of the most common QOL complaints among breast cancer survivors; as many as 70% report memory loss and difficulty concentrating, however, objective tests of cognitive function typically show only 15% - 25% of survivors are impaired based on normative criteria. This discrepancy between the high prevalence of subjective complaints and more modest deficits observed in objective tests may be because standard neuropsychological assessments in controlled laboratory or clinic conditions do not map on to the daily activities in which survivors report problems. Second, cognitive impairments may be subtle and although noticeable to a survivor reflecting on her pre-treatment performance, these within-person changes may not be detectible as differences between survivors. Finally, cognitive impairment among breast cancer survivors may be related to other common QOL outcomes (e.g., stress, depression, fatigue) which may differ between people and fluctuate for a given survivor across time. That is, a survivor may have “good days” and “bad days” in terms of her daily cognitive functioning, and these fluctuations may be predicted by whether she is feeling fatigued, depressed, or stressed on that day. To address these issues, data will be collected from breast cancer survivors who were treated with chemotherapy. Cognitive functioning will be assessed in these individuals using self-report questionnaires and neuropsychological instruments as well as with daily diary reports of memory failures, and cognitive tasks administered as `brain games’ on smartphones across a 14-day period.
