Abstract:
Cognitive function is an important consideration in the assessment and management of older adults with cancer. The development of cancer and cognitive impairment share common risk factors associated with the ageing process. Furthermore, older adults with cancer and cognitive problems are more likely to encounter adverse outcomes. This review by the Young International Society of Geriatric Oncology is divided into the following core sections: cognitive screening, approach to the older adult with pre-existing cognitive impairment, and approach to the older adult presenting with declining cognition. It aims to provide oncologists treating older adults with key considerations when it comes to cognition in this cohort of patients, guidance on differentiating between delirium, cancer related cognitive decline and neurocognitive disorder and some important considerations when it comes to decision-making ability in the context of cognitive decline.
