This book presents the latest research that shows how design thinking, making, and acting contribute to the co-designing and development of products, spaces, and services with people living with dementia.We know that there is currently no cure for the 130+ kinds of dementia that millions of people live with all over the world, but the designed interventions such as the products, spaces, and services described in this book can address stigma, isolation, loss of confidence, and raise awareness and greater understanding of dementia. This book showcases a range of innovative and creative design interventions that have been developed to break the cycle of well-established opinions, strategies, mindsets, and ways of doing that tend to remain unchallenged in the health and social care of people living with dementia. The book will be of interest to scholars working in product design, service design, experience design, architecture, design research, information design, user-centred design, and design for health.
