As the ageing population grows globally, the need for informal care-usually provided by family and friends-will continue to increase. Numbers of people with dementia also continue to rise, and much of their care will be provided by relatives. As such, more people who may themselves be older, will take on such caring roles. Consequently, more carers are likely to have education and support needs. Amidst government recognition of the need to provide good quality, person-centred education and support to carers, there are tensions between the potential for such provision to be resource intensive and whether existing services have the capacity to meet the needs of carers. Massive Open Online Courses (MOOCs) are a resource with scope to meet some of these educational and support needs. MOOCs enable flexible learning, are often free, and can be accessed anywhere in the world. Providing supportive dementia care requires carers to have an understanding of the condition, assistance to cope with the responsibilities of caring, and recognition of the importance of their own health and wellbeing as well as the person they support. In response to the needs of family carers of people with advancing dementia identified through a 5 year programme of research, we developed a MOOC-dementia care: living well as dementia progresses. This is an accessible source of relevant and engaging information; which enables carers to learn about advancing dementia, consider their own needs and create an interactive global forum of peer support.
