Professional interests

Roxane Weijenberg (1979) is a PhD-student at the Clinical Neuropsychology department at the VU University in Amsterdam. Her research is mainly focused on the relationship between mastication (i.e. the act of chewing) and cognition. In collaboration with many nursing homes across the Netherlands, she is working on a longitudinal study examining the effect of mastication through improved oral health care and improved diet on cognition, mood, quality of life and circadian rhythm in psychogeriatric nursing home residents. Roxane studied biology at Utrecht University, specializing in both neuro-ethology and Environmental Education. She spend a year teaching at Wolfridge ELC, in Minnesota, USA, during which a great sense of wonder was instilled.

Research methods. Neuropsychological tests (paper & pencil), questionnaires, actigraphy, oral examinations including mixing ability tests.
Interventions. Implementation of improved oral health care and dietary adaptations in the daily care in psychogeriatric care units, to stimulate mastication. Research design is focused on randomized controlled trails.

Clinical relevance of the research. In view of the aging population, maintenance of good (oral) health is vital. Non-pharmacological interventions such as oral health care are of great societal and financial importance. Executive dysfunctions, mood disturbances, apathy and impaired sleep are very important predictors of institutionalization. Potential positive effects of mastication on those factors are very relevant to enhance quality of life.
