The European costs of dementia were estimated €177 billion and there is a growing gap between burden and budget. The debilitation associated with dementia makes it the most feared of conditions related to ageing .Modelling studies have estimated that if obesity rates dropped by 5%, dementia prevalence rates would be lower by 6% and a decline in physical inactivity rate by 5% would reduce dementia by 11%. For even a very small delay in disease onset of 1 year it is estimated that this would decrease dementia prevalence worldwide by 12 million fewer cases by 2050.The current European road map for the prevention of dementia indicated that prevention needs to start years before symptoms become apparent and needs to be multi-domain focussed. Dementia has complex and interacting aetiologies including, poor diet, cardiovascular problems, low exercise levels, low cognitive stimulation and mood problems. Clearly these risk factors are shared with many other diseases of ageing and interventions for them already exist around Europe in many cases.This project seeks to design and test a stare of the art electronic system for use in primary care to profile individual’s dementia risks and respond to those risks with a combination of the best available on-line strategies and locally sourced options. This will be achieved through advanced web search and aggregation technologies. This will enable comprehensive state of the art assessment, multi-use of programmes already designed for such risk modification, flexibility for the end user, and ease of use for primary care staff. The intervention is aimed at people in their sixth decade.
