Development of a risk index for cognitive decline predicted by adverse radiation events and diet in older oral cancer patients

Professor Norimasa Ogama, Faculty of Nursing, Soka University, is interested in how symptoms such as dry mouth and changes in taste in elderly oral cancer patients could predict the risk of decline in cognitive function with the use of different sensory food experiences. He is developing an index to predict this. While previously at the Department of Head and Neck Surgery, Aichi Cancer Center Hospital, Ogama saw a range of problems among patients caused by radiation and chemotherapy, including reduced eating and swallowing function, changes in body image and ongoing issues with being able to eat and speak. He began to consider how it might be possible to improve quality of life for such patients, including the ability to enjoy food. This inspired him to work to develop an oral rehabilitation programme that takes into account post-operative life evaluation and its influencing factors in order to significantly increase patients’ life satisfaction. Ogama and the team are developing a risk index for cognitive decline predicted by the adverse events of radiation and the diet of elderly patients with oral cancer. The goal is to accurately determine the risk of cognitive decline early based on changes to eating preferences and the taste of food, as well as worsening of oral mucositis and symptoms of dry mouth due to radiation therapy. This will be done through the concept of ‘eating deliciously’, based on personal preferences and characteristics.
