Alzheimer Europe reports that at least 5.7 million Europeans, aged between 40 and 80, have Parkinson's disease or dementia. With an aging population, an estimated 10 million new cases of Parkinson's and dementia is expected within the next 40 years. Care is provided by nursing homes and specialised centres to 70% of advanced dementia patients. So today, European researchers are tackling the problem of how people with these diseases can keep their independence and quality of life longer, while safely living in their own homes. The Rosetta project is funded under the Ambient Assisted Living Programme, the EU's R&D funding programme addressing demographic ageing in Europe.
