The increasing prevalence of Alzheimer's disease and other forms of dementia causes new challenges to ensure that healthcare decisions are informed by research evidence and reflect what is important for seniors and their caregivers. Primary care providers point to a need for more training on communication with families of seniors living with dementia, and on the non-pharmacological health options that are often recommended before use of medications.Therefore, the investigators will design and evaluate an intervention to train primary healthcare providers on how to empower seniors with dementia and their caregivers in making health-related decisions based on research evidence and on their preferences and priorities. A distance professional training program on shared decision making will initially be designed, comprising evidence summaries to be shared with patients living with dementia and their caregivers who face difficult decisions. Patients with dementia, their caregivers and healthcare providers, will then provide feedback on the training program, which will then be improved following their suggestions. In a last step, the investigators will evaluate whether this training program truly increases the participation of patients and their caregivers in decision making, their comfort with the decision that they have made, and their motivation and ability to control their life by taking care of their own health.
