In the absence of curative pharmaceutical treatment for evolving cognitive impairment, non-drug interventions are key components in patients' and caregivers' care. These interventions, when combined and adapted to the needs of the patient and the caregiver, allow for maintaining functional autonomy, decreasing caregiver burden and, possibly, slowing down cognitive decline. An on-going study in Suisse Romande (INDID-MCI-QOL) assesses the effect of the number and type of interventions conducted over a year on the evolution of physical, psychological and cognitive health in this population.
