In 2015, 46.8 million people were believed to be living with dementia, with that number expected to increase to near 50 million by 2017. At regular intervals, this figure will nearly double, reaching 75 million by 2030 and 131.5 million by 2050. The expansion will take place in large part in developing countries. Currently, 58 percent of people with dementia live in low- and middle-income countries; but, by 2050, this number will rise to 68 percent. India, China, and their south Asian and western Pacific neighbors are experiencing the fastest growth in the elderly population.
Statistics maturing is a broad process that takes into account medical advances over the last century. Many people are now enjoying longer and more fulfilling lives, resulting in a larger proportion of older people in the population. Despite an increasing awareness of dementia cases that begin before the age of 65, dementia mostly affects the elderly.
More than 9.9 million new cases of dementia are diagnosed per year around the world, meaning one case every 3.2 seconds.
The ADI’s global estimates of dementia’s prevalence, incidence, and costs, which are based on credible surveys, are updated in the World Alzheimer Report 2015.The study makes key recommendations for putting together a global dementia-related activity plan. The research also looks at the evidence for and against late developments in the prevalence and incidence of dementia over time, as well as the effect of dementia on society as a whole.
