By 2050, dementia is expected to affect 152 million people worldwide. There is no cure and few treatments that can help slow the disease's progression or manage the symptoms. However, design can play a significant role in creating safe, comfortable, and stimulating environments for people with dementia. This lecture will discuss the role of environmental design interventions in mitigating disruptive behaviors, improving quality of life, reducing stress, and providing support for caregivers. Explore how these strategies can help bridge the emotional experience with sensory, perceptive, and reminiscent memory to help mitigate disruptive behaviors and their triggers. Design can transform caring for those with dementia from merely keeping them safe to providing a rich experience. Environmental design interventions can help decode dementia's visceral world and support non-cognitive human experiences improving the health, safety and wellbeing of the person living with dementia and those that support them.
