Dementia is defined as a group of cognitive conditions that also includes Alzheimer’s disease. Dementia generally affects two primary brain functions, memory retention and judgment. Symptoms of dementia include limited thinking abilities, impaired social skills and forgetfulness. And, while treatment can provide those living with dementia with some relief, it’s not possible to completely cure the condition.Dementia Around The World As of 2019, more than 50 million people around the world are living with dementia. This condition affects about 5.2% of people above 60, and, based on the growth of cases, it is expected that by 2050, about 152 million people will have dementia. East Asia is the most affected region with about 10 million people who are living with dementia, followed by 7.5 million people in Western Europe, 5.1 million in South Asia and 4.8 million in North America. By 2050, it is expected that nearly 14.5 million will have dementia in Western Europe. The increase of with dementia will be higher in low-income countries at 264% by 2050, 227% in upper middle income countries, 223% in lower middle income countries and just 116% in high income countries. There are about ten million new cases of dementia worldwide each year or about one case every 3.2 seconds. Worldwide Cost Of Dementia Because dementia can’t be completely treated and it has long-term effect on individuals, the worldwide cost is very high. In 2015, the global cost of dementia was nearly £631 billion or about 1.09% of the global GDP. The global cost of dementia has surpassed £770 billion by 2018. Direct costs of dementia include the costs of dementia treatment, both in primary and secondary care. Indirect costs include necessary changes in home settings and loss of productivity. Undiagnosed Dementia In many developing and low-income countries, cases of dementia don’t receive formal diagnosis. In fact, less than 50% of cases of dementia in high income countries are diagnosed and treated with primary care. The gap is certainly much greater in any developing country. It is suggested that as high as 90% of dementia cases in India are undiagnosed. Based on rough extrapolation, it is possible that about 75% of people with dementia worldwide don’t get a diagnosis and proper care. The lack of effective treatment and care causes a steady decline in quality of life among affected individuals.
