The Alzheimers Disease Crisis By The Numbers

Kids Interview People With Dementia Alzheimers Society, Dementia Action Week 2019

Alzheimers is not a normal part of agingit is a devastating disease.

Alzheimers disease and related dementias can be emotionally and financially ruinous for people living with the disease, their caregivers and families, and society at large. Alzheimers disease and other dementias have catastrophic healthcare, economic, and social impactsand these impacts are rapidly growing.

Barrons Magazine describes it as the coming Alzheimers crisis The Economist describes the rising prevalence of dementia as a global emergency.

Someone in the United States develops Alzheimers every 60 seconds. By 2050 this is projected to be every 33 seconds.

Alzheimers disease is the most common form of dementia, a progressive brain disease that slowly destroys memories and thinking skills. Alzheimers often starts 5, 10, or even 20 years before symptoms appear. Symptoms usually start with difficulty remembering new information. In advanced stages, symptoms include confusion, mood and behavior changes, and inability to care for ones self and perform basic life tasks. Alzheimers is ultimately fatal.

The risks and ramifications extend beyond Alzheimers disease itself. People living with Alzheimers are twice as likely to get the COVID-19 virus than other people – and they also face accelerated cognitive decline from well-intended quarantine measures.

Is Alzheimers A Leading Cause Of Death

Alzheimers is the sixth-leading cause of death in the U.S., but the National Institute on Aging notes that among older people, the disease could be the third leading cause of death, right behind heart disease and cancer.

The Alzheimers Association found that Alzheimers deaths have increased by 145 percent between 2000 and 2017. A 2014 study discovered that in 2010, nearly 503,400 people who were over age 75 died from some form of dementia. This estimate was about five times higher than most predictions.

A report by Public Health England found that in 2016, Alzheimers disease and other forms of dementia were the most common cause of death in the U.K. among women. The report states that while mortality rates were decreasing for cardiovascular disease and various types of cancer, mortality rates for Alzheimers are expected to rise between 2017 and 2023. A more recent report by Alzheimers Research UK states that Alzheimers and other types of dementia are now the main cause of death in the U.K. Here, dementia was the main cause of death for women and second leading cause of death for men.

The WHO predicts that worldwide, dementia deaths will increase by more than 40 percent between 2015 and 2030.

What Percentage Of People Over The Age Of 80 Have Dementia

In 2015, about 5% of adults aged 70 to 79 had probable dementia, compared to 16% of adults aged 80 to 89 and 31% of adults aged 90 and older. As the United States population ages, the number of people with dementia is expected to rise dramatically. Women are slightly more likely than men to develop dementia.

Cbd Can Potentially Reverse The Aging Of The Brain

Alzheimers disease research performed by scientists at the University of Bonn and The Hebrew University of Jerusalem demands attention. The study done on mice showed that CBD can reverse the aging of the brain accelerated by Alzheimers disease. Old mice were brought into the state of two-month-old mice. Hopefully, this will inspire more research on CBD oil for Alzheimers for people.

Who Is At Risk From Mental Disorders

Alzheimer Epidemiology / Epidemiology Of Alzheimer S ...

Determinants of mental health and mental disorders include not only individual attributes such as the ability to manage one’s thoughts, emotions, behaviours and interactions with others, but also social, cultural, economic, political and environmental factors such as national policies, social protection, standards of living, working conditions, and community support.

Stress, genetics, nutrition, perinatal infections and exposure to environmental hazards are also contributing factors to mental disorders.

Common Forms Of Dementia

There are many different forms of dementia. Alzheimer’s disease is the most common form and may contribute to 60-70% of cases. Other major forms include vascular dementia, dementia with Lewy bodies , and a group of diseases that contribute to frontotemporal dementia . Dementia may also develop after a stroke or in the context of certain infections such as HIV, harmful use of alcohol, repetitive physical injuries to the brain or nutritional deficiencies. The boundaries between different forms of dementia are indistinct and mixed forms often co-exist.

Impact On Families And Carers

In 2019, informal carers spent on average 5 hours per day providing care for people living with dementia. This can be overwhelming . 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. Fifty percent of the global cost of dementia is attributed to informal care.

What Is Known About Alzheimers Disease

Scientists do not yet fully understand what causes Alzheimers disease. There likely is not a single cause but rather several factors that can affect each person differently.

  • Age is the best known risk factor for Alzheimers disease.
  • Family historyresearchers believe that genetics may play a role in developing Alzheimers disease. However, genes do not equal destiny. A healthy lifestyle may help reduce your risk of developing Alzheimers disease. Two large, long term studies indicate that adequate physical activity, a nutritious diet, limited alcohol consumption, and not smoking may help people. To learn more about the study, you can listen to a short podcast.
  • Changes in the brain can begin years before the first symptoms appear.
  • Researchers are studying whether education, diet, and environment play a role in developing Alzheimers disease.
  • There is growing scientific evidence that healthy behaviors, which have been shown to prevent cancer, diabetes, and heart disease, may also reduce risk for subjective cognitive decline. Heres 8 ways.

Schizophrenia And Other Psychoses

Schizophrenia is a severe mental disorder, affecting 20 million people worldwide1. Psychoses, including schizophrenia, are characterized by distortions in thinking, perception, emotions, language, sense of self and behaviour. Common psychotic experiences include hallucinations and delusions . The disorder can make it difficult for people affected to work or study normally.

Stigma and discrimination can result in a lack of access to health and social services. Furthermore, people with psychosis are at high risk of exposure to human rights violations, such as long-term confinement in institutions.

Schizophrenia typically begins in late adolescence or early adulthood. Treatment with medicines and psychosocial support is effective. With appropriate treatment and social support, affected people can lead a productive life and be integrated in society. Facilitation of assisted living, supported housing and supported employment can act as a base from which people with severe mental disorders, including schizophrenia, can achieve numerous recovery goals as they often face difficulty in obtaining or retaining a place to live and normal employment.

Risk Factors And Prevention

Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of biological ageing. Further, dementia does not exclusively affect older people young onset dementia accounts for up to 9% of cases. Studies show that people can reduce their risk of cognitive decline and dementia by being physically active, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels. Additional risk factors include depression, social isolation, low educational attainment, cognitive inactivity and air pollution.

    Alzheimers Statistics United States & Worldwide Stats

    We know that Alzheimers affects so many lives around the globe, but to what extent? How many individuals are directly affected by Alzheimers and how many are receiving care? This condition is incredibly serious, as so many lives are being affected on a daily basis. In fact, out of the top ten causes of death in America, Alzheimers is the only condition which cannot be slowed down, prevented, or cured.

    A Costly And Growing National Crisis

    • In 2021, the total national cost of caring for people living with Alzheimers and other dementias is projected to reach $355 billion. This number does not include the estimated $257 billion price of unpaid caregiving.
    • Medicare and Medicaid are expected to cover $239 billion, or 67%, of the total health care and long-term care payments for people with Alzheimers or other dementias. Out-of-pocket spending is expected to be $76 billion, or 22% of total payments.

    Alzheimer’s Society’s View On Demography

    The number of people with dementia is steadily increasing. We believe that careful planning is needed.

    Alzheimer’s Society believes that careful planning for the future is needed now to ensure that the right care and support is available.

    The report, Projections of older people with dementia and costs of dementia care in the United Kingdom, 2019-2040 , provides the most up-to-date evaluation of the numbers of people with dementia in the UK, projections on numbers of people in the future and the prevalence of dementia.

    This research was conducted by the Care Policy and Evaluation Centre at the London School of Economics and Political Science on behalf of Alzheimers Society.

    What Gender Is Most Impacted By Alzheimers Disease

    Australia: Queensland cafe for Dementia patients aims to improve community engagement

    Alzheimers is often referred to as a womans disease. Recent facts show that two-thirds of all Alzheimers cases are in women.

    Researchers are still investigating why women are more likely to develop Alzheimers than men are.

    The Alzheimers Associations 2019 report suggests that while scientists previously thought the discrepancy is due to women living longer, some researchers think genetics, hormones or lifestyle could lead to a higher incidence of Alzheimers among women.

    Dr. Marie Pasinski, a faculty member at Harvard Medical School and neurologist at Massachusetts Generals Institute for Brain Health said scientists have found that women have more Alzheimers risk factors than men. For example, studies have found that lower education levels, limited exercise and stress can all be detrimental to brain health. Pasinski said that in the past, women were not afforded as many educational opportunities as men and were often excluded from sports, putting them at a disadvantage when it comes to brain health.

    Also, more women than men become caregivers for a sick parent or child, something that could increase stress levels. In addition to exploring how lifestyle experiences may put women at a greater risk for Alzheimers, scientists like Dr. Pauline Maki are studying how hormones could impact memory, including the connection between estrogen, menopause and memory loss.

    Risk Factors For Alzheimer’s Dementia

    The vast majority of people who develop Alzheimer’s dementia are age 65 or older. This is called late-onset Alzheimer’s. Experts believe that Alzheimer’s, like other common chronic diseases, develops as a result of multiple factors rather than a single cause. Exceptions are cases of Alzheimer’s related to uncommon genetic changes that increase risk.

    2.7.1 Age, genetics and family history

    The greatest risk factors for late-onset Alzheimer’s are older age,, genetics, and having a family history of Alzheimer’s.-

    Age

    Age is the greatest of these three risk factors. As noted in the Prevalence section, the percentage of people with Alzheimer’s dementia increases dramatically with age: 3% of people age 65-74, 17% of people age 75-84 and 32% of people age 85 or older have Alzheimer’s dementia. It is important to note that Alzheimer’s dementia is not a normal part of aging, and older age alone is not sufficient to cause Alzheimer’s dementia.

    Genetics

    APOE Pair
    • One in 10 people age 65 and older has Alzheimer’s dementia.,,
    • The percentage of people with Alzheimer’s dementia increases with age: 3% of people age 65-74, 17% of people age 75-84, and 32% of people age 85 and older have Alzheimer’s dementia. People younger than 65 can also develop Alzheimer’s dementia, but it is much less common and prevalence is uncertain.

    Support For Family And Friends

    Currently, many people living with Alzheimers disease are cared for at home by family members. Caregiving can have positive aspects for the caregiver as well as the person being cared for. It may bring personal fulfillment to the caregiver, such as satisfaction from helping a family member or friend, and lead to the development of new skills and improved family relationships.

    Although most people willingly provide care to their loved ones and friends, caring for a person with Alzheimers disease at home can be a difficult task and may become overwhelming at times. Each day brings new challenges as the caregiver copes with changing levels of ability and new patterns of behavior. As the disease gets worse, people living with Alzheimers disease often need more intensive care.

    Economic Impact Of Dementia

    The total estimated worldwide cost of dementia was US$ 818 billion in 2015, which represented 1.09% of global GDP at that time. The annual global cost of dementia is now above US$ 1.3 trillion and is expected to rise to US$2.8 trillion by 2050

    This figure includes costs attributed to informal care , direct costs of social care and the direct costs of medical care .

    Direct medical care costs account for roughly 20% of global dementia costs, while direct social sector costs and informal care costs each account for roughly 40%. The relative contribution of informal care is greatest in the African regions and lowest in North America, Western Europe and some South American regions, while the reverse is true for social sector costs.

    This means that if global dementia care were a country, it would be the 14th largest economy in the world. More information is available in our World Alzheimer Report 2015.

    Racial And Ethnic Differences In The Prevalence Of Alzheimer’s And Other Dementias

    Although there are more non-Hispanic whites living with Alzheimer’s and other dementias than any other racial or ethnic group in the United States , older black/African Americans and Hispanics/Latinos are disproportionately more likely than older whites to have Alzheimer’s or other dementias., , – Most studies indicate that older black/African Americans are about twice as likely to have Alzheimer’s or other dementias as older whites., , Some studies indicate older Hispanics/Latinos are about one and one-half times as likely to have Alzheimer’s or other dementias as older whites.,, , However, Hispanics/Latinos comprise a very diverse group in terms of cultural history, genetic ancestry and health profiles, and there is evidence that prevalence may differ from one specific Hispanic/Latino ethnic group to another .,

    There is evidence that missed diagnoses of Alzheimer’s and other dementias are more common among older black/African Americans and Hispanics/Latinos than among older whites., Based on data for Medicare beneficiaries age 65 and older, it has been estimated that Alzheimer’s or another dementia had been diagnosed in 10.3% of whites, 12.2% of Hispanics/Latinos and 13.8% of black/African Americans. Although rates of diagnosis were higher among black/African Americans than among whites, according to prevalence studies that detect all people who have dementia irrespective of their use of the health care system, the rates should be even higher for black/African Americans.
