The Ability research project, funded in Italy within the Smart Cities and Smart Communities funding program (MInistry of University and Research, Operational Regional Programme, Lombardy, Axis 1, Operational Regional Programme - European Funding for Regional Development 2007-2013), aims at developing and testing the efficacy and the impact of a Personal Smart Health Community able to provide innovative trajectories for people with cognitive impairment, putting them at the core of a continuous and intertwining treatment and support from both formal (e.g. physicians) and informal (e.g. near relatives) caregivers, with special focus on home-based care.
