MODEM - Comprehensive approach to modelling outcome and cost impacts of interventions for dementia - will develop a comprehensive set of quantitative models to forecast how many people will develop dementia in England over the next 30 years; the unpaid support services available from family and other carers; and the projected costs of their treatment and care. It will be carried out in collaboration with researchers from the London School of Economics and Political Science, Newcastle University, the University of Southampton, University of Sussex and the International Longevity Centre-UK. It is one of six dementia projects being funded under a major new ESRC/NIHR programme.
