The prevalence of dementia cases seems to increase every year, and also new incidents of the same condition are alarming. Reflecting on the U.S, more than 5 million Americans have Alzheimer’s.

According to statistics, the societal, economic cost of dementia in 2015 was (US) $818 billion annually. That equals 1.1% of the world’s gross domestic product (GDP). 

2017 study compared the costs of dementia from 2010 to 2015. It was evident that there was an increase in cost by 35%, respectively. The increase was a result of the increased cost of social care, informal care, and medical care triggered by increased numbers of people with dementia. Finally, the worldwide costs of dementia are huge and unevenly distributed.

  • Dementia kills

In many cases, people are only focused on how dementia affects how the brain functions and causes an inability to perform basic activities. On the other hand, dementia contributes to a high mortality rate. According to the Alzheimer’s Association, 1 out of 3 seniors dies with Alzheimer’s or another form of dementia.

A 2017 report by the U.S based Center for Disease Control (CDC) researchers, showed that age-adjusted death rates for dementia increased from 30.5 per 100,000 in 2000 to 66.7 in 2017. Besides, 64% of deaths linked to dementia occurred in long term care facilities, nursing homes, and hospice facilities, while 22.9% were in decedent homes, and 8.7% of death occurred in medical facilities. Deaths linked to Alzheimer’s disease have increased to 146% while those caused by heart disease, i.e., the leading cause of death has dropped by 7.8%. Besides, those diagnosed with dementia and are over 65 years old have a lifespan of 4-8 years, while others can live for 20 years with the same condition. 

Dementia is the 5th leading cause of death around the globe. Analysis from “Our World in Data Organization”, showed that dementia is among the non-communicable disease highly contributing to the deaths of people over 69 years old. Alzheimer’s Research UK cites Dementia as the leading cause of death in the UK over recent years. There is a probability of 40% increase in the global number of deaths from 2015 to 2030 as a result of dementia.

  • There exist discrimination against people with dementia and their families

In different parts of the globe, people with dementia are often denied some basic human rights, they are discriminated against, and even treated unequally as others. Among are common instances that depict discrimination of people living with dementia include:
