The Interdisciplinary Dementia and Ageing Centre (IDeAC) is the close collaboration between academics (who are testing ideas), NHS staff (who are involved in day-to-day diagnosis and care), engineers (for technological development and modelling), mathematicians (for modelling processes) and industry (who develop new treatments). The IDeAC network includes basic scientists, clinicians, health and social care delivery researchers, epidemiologists, imagers, mathematicians, and computing and data scientists. The network consists of four synergistic themes, each covering a range of specialties within the field of dementia research and care.
