title: Cognition and Cognitive Impairment in Older Adults with Cancer.
abstract: Aging is a risk factor for cognitive impairment as well as cancer. However, the interplay between these three entities - aging, cognition and cancer - is not well understood. Mounting evidence indicates that both cancer and cancer therapies, such as chemotherapy, can negatively affect cognition and that older adults with pre-existing cognitive impairment may be more susceptible to cognitive decline with therapy than younger patients. For an older adult, decline in cognition may significantly compromise their ability to remain independent in the community. Pre-existing cognitive impairment, at the time of a cancer diagnosis, may also carry an increased risk of treatment-related adverse events in older adults receiving chemotherapy. Growing research suggests behavioral interventions may be helpful in improving chemotherapy-related cognitive changes; however, these interventions have been mainly evaluated in younger patients in whom pre-existing cognitive impairment is less prevalent. Here we review the studies on: cognitive changes associated with cancer and cancer therapies with an emphasis on studies conducted in older adults, relevant screening tools to evaluate cognition in the geriatric oncology setting, and possible intervention strategies for managing cognitive impairment.
