Background: Dementia affects not only the patients, but also the caregivers. Timely targeted supporting for informal caregivers of people with dementia can improve their health and life quality, as well as contribute to sustainable healthcare. However, which interventions could efficiently support them and why still remains unclear. Objectives: This systematic review aims to close this gap by critically assessing the current state of randomized controlled evidence concerning informal caregivers of older people with early dementia.
