It is now estimated that in 2013 44.3 million people worldwide were living with dementia, this figure nearly doubling every twenty years to reach 135.5 million by the year 2050. Dementia is a syndrome in which there is deterioration in memory, thinking, behaviour and the ability to perform everyday activities. Worldwide, around 50 million people have dementia, and there are nearly 10 million new cases every year. Alzheimer’s Disease International Search for a statistic Dementia in sub-Saharan Africa: Challenges and Opportunities, We need to be talking more about older people who need care in low and middle income countries. 50 However, this study might have underestimated indirect costs by only including the time spent on caregiving in the analysis, while ignoring the lost productivity and income … 88-106. Of the 326 million Americans currently living, approximately 45 million will develop Alzheimer's disease during their lifetimes unless effective prevention programs are instituted. Under principal investigator Christopher J.L. By 2050, increases will be much sharper in low and middle income countries (246%), than in high income countries (131%). providing information and long-term support to carers. Much of this increase is attributable to the rising numbers of people with dementia living in low- and middle-income countries. Recent results 4. Results: Age-standardized prevalence for those aged 60 years varied in a narrow band, 5%–7% in The total cost as a proportion of GDP varied from 0.2% in low- and middle-income countries to 1.4% in high-income countries. Studies show that people can reduce their risk of dementia by getting regular exercise, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels. from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 Dementia Collaborators presents estimates of dementia-related deaths, prevalence, quality of life measures, and risk factors, with the aim of documenting global patterns and providing data for research, and to guide a wide range of public health investments. Background: Our goal was to forecast the global burden of Alzheimer's disease and evaluate the potential impact of interventions that delay disease onset or progression. Symptoms include: There are many different forms of dementia. Most comprehensive global study—analysing 286 causes of death, 369 diseases and injuries, and 87 risk factors in 204 countries and territories—reveals how well the world’s population were prepared in terms of underlying health for the impact of the COVID-19 pandemic. GBD 2016 Dementia Collaborators 2019, ' Global, regional, and national burden of Alzheimer's disease and other dementias, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016 ', The Lancet Neurology, vol. WHO is also developing a knowledge exchange platform to facilitate the exchange of good practices in the area of dementia. The signs and symptoms linked to dementia can be understood in three stages. Dementia affects each person in a different way, depending upon the impact of the disease and the person’s personality before becoming ill. Dementia is 1 of the 5 major global causes of death.1 In 2015/2016, an estimated 43–47 million people were living with dementia disease, expected to increase to over 100 million by 2050.1 The largest increase is anticipated in low- and middle-income countries.1 To give policy makers a tool to delay the onset of dementia, it is pertinent to map the contributing risk factors nationally. A new publication, based on research conducted by OHE, suggests that by 2025 the disability adjusted life year (DALY) burden of dementia will have increased by 42% from the Global Disease Burden (GDB) 2010 estimate. The information from prevalence and incidence studies in Latin America, India, and China has been synthesised with new data from other research studies, and used to generate new estimates of numbers affected worldwide, published in ADIs 2009 World Alzheimer Report and the World Health Organizations 2012 report: Dementia: a Public Health Priority 2012. Further, dementia does not exclusively affect older people – young onset dementia (defined as the onset of symptoms before the age of 65 years) accounts for up to 9% of cases.

This is more than stroke (9.5%), musculoskeletal disorders (8.9%), cardiovascular disease (5.0%), and all forms of cancer (2.4%). The impact of dementia on carers, family and society at large can be physical, psychological, social and economic. An international surveillance platform, the Global Dementia Observatory (GDO), has been established for policy-makers and researchers to facilitate monitoring and sharing of information on dementia policies, service delivery, epidemiology and research. More comprehensive and multi-dimensional approaches, including clinical, psychological, social, and political means will be needed for the management of the dramatically increasing burden of dementia. There is often a lack of awareness and understanding of dementia, resulting in stigmatization and barriers to diagnosis and care. Dementia results from a variety of diseases and injuries that primarily or secondarily affect the brain, such as Alzheimer's disease or stroke. Common symptoms include: Middle stage: as dementia progresses to the middle stage, the signs and symptoms become clearer and more restricting. The estimated proportion of the general population aged 60 and over with dementia at a given time is between 5-8%. Early stage:the early stage of dementia is often overlooked, because the onset is gradual. A response to the need for comprehensive, consistent and comparable information on diseases and injuries at global and regional level. In 2016, the global number of individuals who lived with dementia was 43.8 million (95% uncertainty interval [UI] 37.8–51.0), increased from 20.2 million (17.4–23.5) in 1990. Qiu C, Fratiglioni L (2018) Aging without dementia is achievable: current evidence from epidemiological research. Dementia can be overwhelming for the families of affected people and for their carers. Middle stage:… The largest increases in projected numbers of people with dementia are those for the Asia East and sub-Saharan African regions, accounted for by the higher age-specific prevalence of dementia estimated in our new reviews of survey from thse regions. According to the Global Burden of Disease (GBD) estimates from the 2003 World Health Report, dementia contributed 11.2% of the YLD in people aged 60 years and older. The systematic analysis of the Global Burden of Disease Study 2016 found dementia was more common at older ages, with the prevalence doubling every five … However, much can be offered to support and improve the lives of people with dementia and their carers and families. New figures show an estimated 44 million people worldwide now have dementia, up from 35 million in 2010, and that number will reach 76 million in 2030, and 135 million by 2050. Every year, there are nearly 10 million new cases. Case definition for Alzheimer’s disease and other dementias 3. Health economics. Nichols E (2019) Global, regional, and national burden of Alzheimer’s disease and other dementias, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016. There is no treatment currently available to cure dementia or to alter its progressive course. If current trends continue, by 2050 we can expect about 200 million stroke survivors and 106 million people with dementia, and each year thereafter, over 30 million new strokes, 12 million deaths from stroke, and almost The first ‘Global Burden of Disease’ (GBD) was GBD 1990 and the DALY metric was prominently featured in the World Bank’s 1993 World Development Report. In 2011, the High-level Meeting of the United Nations General Assembly on prevention and control of non-communicable diseases adopted a Political Declaration that acknowledged that “the global burden and threat of non-communicable diseases constitutes one of the major People with dementia are frequently denied the basic rights and freedoms available to others. early diagnosis in order to promote early and optimal management, optimizing physical health, cognition, activity and well-being, identifying and treating accompanying physical illness, detecting and treating challenging behavioural and psychological symptoms.

In 2015, the total global societal cost of dementia was estimated to be US$ 818 billion, equivalent to 1.1% of global gross domestic product (GDP). Numerous new treatments are being investigated in various stages of clinical trials. becoming forgetful of recent events and people's names, having increasing difficulty with communication. Early stage: the early stage of dementia is often overlooked, because the onset is gradual. Other major forms include vascular dementia, dementia with Lewy bodies (abnormal aggregates of protein that develop inside nerve cells), and a group of diseases that contribute to frontotemporal dementia (degeneration of the frontal lobe of the brain). Dementia poses a heavy burden on patients and their families. View publication. The boundaries between different forms of dementia are indistinct and mixed forms often co-exist. Alzheimer’s disease is a global pandemic and the third leading cause of death in the United States. Methods: In this study we provide a systematic review of the global literature on the prevalence of dementia (1980–2009) and metaanalysis to estimate the prevalence and numbers of those affected, aged 60 years in 21 Global Burden of Disease regions. The Plan provides a comprehensive blueprint for action – for policy-makers, international, regional and national partners, and WHO as in the following areas: addressing dementia as a public health priority; increasing awareness of dementia and establishing dementia-friendly initiatives; reducing the risk of dementia; diagnosis, treatment and care; information systems for dementia; support for dementia carers; and, research and innovation. (mhGAP), which included dementia as a priority condition. World Alzheimer’s Report 2015, The Global Impact of Dementia: An analysis of prevalence, incidence, cost and trends. Worldwide, dementia (mostly Alzheimer's disease… WHO recognizes dementia as a public health priority. The work of the 10/66 Dementia Research Group has substantially updated our understanding of the global prevalence and impact of dementia. The Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study has published regular updates of estimates for dementia in 195 countries and territories and subnational locations, such as the provinces of China and states in countries such as Brazil, the USA, and Mexico. WHO has developed Towards a dementia plan: a WHO guide, which provides guidance to Member States in creating and operationalizing a dementia plan. Dementia is also one of the priority conditions in the WHO Mental Health Gap Action Programme (mhGAP), which is a resource for generalists, particularly in low- and middle-income countries, to help them provide first-line care for mental, neurological and substance use disorders. Dementia affects each person in a different way, depending upon the impact of the disease and the person’s personality before becoming ill.

It affects memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. The updated estimates are higher than the original estimates reported in the 2009 World Alzheimer Report, by 15% in 2030 and by 17% in 2050. The authors mainly attribute this doubling in global disease burden to increases in population aging and growth. Dementia has a physical, psychological, social, and economic impact, not only on people with dementia, but also on their carers, families and society at large. Notably, the number of deaths due to dementia increased by 148 percent between 1990 and 2016; it was the fifth-largest cause of death globally in 2016, and the second largest cause of death in individuals aged more than 70 years. The guide is closely linked to WHO’s GDO and includes associated tools such as a checklist to guide the preparation, development and implementation of a dementia plan. Physical, emotional and financial pressures can cause great stress to families and carers, and support is required from the health, social, financial and legal systems. ...
