Dementia in an Aging World

Abstract

Both developed and developing countries are facing economic and social challenges posed by an aging population. Dementia is one of the most common diseases in old age and has major consequences for society. In 2013, an estimated 44.4 million people worldwide suffered from dementia, and this number is expected to increase to 135.5 million by 2050. The current worldwide costs of dementia have been estimated at $604 billion, primarily due to the high demand for care. There is no known cure for dementia; however, positive developments with respect to lifestyle and recognizing risk factors in young and middle ages might have positive long-term effects on the risk of dementia in old age. Prevention and adequate medical treatment of these risk factors might help postpone dementia into higher ages. In addition, assistive technologies may help to mitigate the family and caregiver burden.
