The Basics Of Alzheimers Disease

Experience 12 Minutes In Alzheimer’s Dementia

Scientists are conducting studies to learn more about plaques, tangles, and other biological features of Alzheimers disease. Advances in brain imaging techniques allow researchers to see the development and spread of abnormal amyloid and tau proteins in the living brain, as well as changes in brain structure and function. Scientists are also exploring the very earliest steps in the disease process by studying changes in the brain and body fluids that can be detected years before Alzheimers symptoms appear. Findings from these studies will help in understanding the causes of Alzheimers and make diagnosis easier.

One of the great mysteries of Alzheimers disease is why it largely affects older adults. Research on normal brain aging is exploring this question. For example, scientists are learning how age-related changes in the brain may harm neurons and affect other types of brain cells to contribute to Alzheimers damage. These age-related changes include atrophy of certain parts of the brain, inflammation, blood vessel damage, production of unstable molecules called free radicals, and mitochondrial dysfunction .

Use And Costs Of Health Care Long

The costs of health care and long-term care for individuals with Alzheimer’s or other dementias are substantial, and dementia is one of the costliest conditions to society. Total payments in 2021 for all individuals with Alzheimer’s or other dementias are estimated at $355 billion , not including the value of informal caregiving that is described in the Caregiving section. Medicare and Medicaid are expected to cover $239 billion, or 67%, of the total health care and long-term care payments for people with Alzheimer’s or other dementias. Out-of-pocket spending is expected to be $76 billion, or 22% of total payments. Throughout the rest of this section, all costs are reported in 2020 dollars unless otherwise indicated.


More Deaths From Alzheimers Disease And Other Dementias In 2020 Report Says

A year ago, Marc and Kathy Cochran were looking forward to a summer trip to Greece. Kathy, 68, had been diagnosed with early-onset Alzheimers disease in 2012, but she was functioning well and enjoying herself, which her husband of 48;years attributed to regular exercise and an active and varied social life.

That crashed to a halt when the novel coronavirus hit. The couple stopped going to restaurants, visiting friends or seeing their adult children. They even had to stop walking their dogs because the gregarious Kathy liked to run up and hug her neighbors and did not understand why that had become unsafe.

The changes put her into a tailspin. It was just like the bottom dropped out, Marc said. I couldnt get her to be calm. In the ensuing months, her cognitive function declined so precipitously that she was moved to a memory-care facility, and she died in September.

Her husband blames the pandemic. I cant tell you that she wouldnt have, but I could see a definite demarcation point from the time we shut down to the time she had to go into memory care, he said. One of the things that made her happy was seeing people, smiling at them, laughing with them, hugging them, and when she couldnt do that … she would become agitated.

About 40;percent of covid-19 deaths in the United States have been residents or staffers of long-term-care facilities, said the report, which is the organizations annual Facts and Figures assessment.

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.

How Many People Have Alzheimers Disease Worldwide


Recent statistics show that about 50 million people around the world have Alzheimers disease or another type of dementia.

Facts from the World Health Organization reveal that about 60 percent of people living with dementia worldwide are from a low- or middle-income country.

The total number of people with dementia is projected to reach 82 million in 2030 and 152 million in 2050, WHO said. To put that in perspective, the current population of the U.S. is 329 million.

In fact, dementia is now the leading cause of death in the United Kingdom, pushing heart disease into second place. This finding comes from the Northern Ireland Statistics and Research Agency and the Office for National Statistics.

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.

Support For Families And Alzheimer’s Disease Caregivers

Caring for a person with Alzheimers can have significant physical, emotional, and financial costs. The demands of day-to-day care, changes in family roles, and decisions about placement in a care facility can be difficult. NIA supports efforts to evaluate programs, strategies, approaches, and other research to improve the quality of care and life for those living with dementia and their caregivers.

Becoming well-informed about the disease is one important long-term strategy. Programs that teach families about the various stages of Alzheimers and about ways to deal with difficult behaviors and other caregiving challenges can help.

Good coping skills, a strong support network, and respite care are other things that may help caregivers handle the stress of caring for a loved one with Alzheimers. For example, staying physically active provides physical and emotional benefits.

Some caregivers have found that joining a support group is a critical lifeline. These support groups enable caregivers to find respite, express concerns, share experiences, get tips, and receive emotional comfort. Many organizations sponsor in-person and online support groups, including groups for people with early-stage Alzheimers and their families.

Use And Costs Of Health Care Services

6.2.1 Use of health care services

People with Alzheimer’s or other dementias have twice as many hospital stays per year as other older people. Moreover, the use of health care services by people with other serious medical conditions is strongly affected by the presence or absence of dementia. In particular, people with coronary artery disease, diabetes, chronic kidney disease, chronic obstructive pulmonary disease , stroke or cancer who also have Alzheimer’s or other dementias have higher use and costs of health care services than people with these medical conditions but no coexisting dementia.

Risk Factors And Prevention

Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of 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 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. Additional risk factors include depression, low educational attainment, social isolation, and cognitive inactivity.

Overview Of Alzheimer’s Disease


Alzheimer’s disease is a type of brain disease, just as coronary artery disease is a type of heart disease. It is also a degenerative disease, meaning that it becomes worse with time. Alzheimer’s disease is thought to begin 20 years or more before symptoms arise,- with changes in the brain that are unnoticeable to the person affected. Only after years of brain changes do individuals experience noticeable symptoms such as memory loss and language problems. Symptoms occur because nerve cells in parts of the brain involved in thinking, learning and memory have been damaged or destroyed. As the disease progresses, neurons in other parts of the brain are damaged or destroyed. Eventually, nerve cells in parts of the brain that enable a person to carry out basic bodily functions, such as walking and swallowing, are affected. Individuals become bed-bound and require around-the-clock care. Alzheimer’s disease is ultimately fatal.

Who Has Alzheimers Disease

  • In 2020, as many as 5.8 million Americans were living with Alzheimers disease.1
  • Younger people may get Alzheimers disease, but it is less common.
  • The number of people living with the disease doubles every 5 years beyond age 65.
  • This number is projected to nearly triple to 14 million people by 2060.1
  • Symptoms of the disease can first appear after age 60, and the risk increases with age.

Medications To Maintain Mental Function In Alzheimer’s Disease

Several medications are approved by the U.S. Food and Drug Administration to treat symptoms of Alzheimers. Donepezil, rivastigmine, and galantamine are used to treat the symptoms of mild to moderate Alzheimers. Donepezil, memantine, the rivastigmine patch, and a combination medication of memantine and donepezil are used to treat moderate to severe Alzheimers symptoms. All of these drugs work by regulating neurotransmitters, the chemicals that transmit messages between neurons. They may help reduce symptoms and help with certain behavioral problems. However, these drugs dont change the underlying disease process. They are effective for some but not all people and may help only for a limited time.

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.

Alzheimers Statistics Amongst Americans

This year, 5.3 million Americans will live with Alzheimers in the United States, with an approximate 5.1 million people being 65 years and older. In terms of gender, 3.2 million are females and 1.9 million are male. Ethnicity also plays a role, as older African-American and Hispanic individuals are more likely to suffer from Alzheimers in comparison to older white individuals.

In terms of mortality rates, an estimated 700,000 people will die this year alone from Alzheimers. It is true that deaths from other major causes have decreased, however, deaths from Alzheimers have significantly increased. Between the years of 2000 and 2013, mortality rates increased by 71 percent.

Last, its important to focus on those who are caregivers and friends and family members provided an approximate 17.9 billion hours of unpaid care last year. This is emotionally taxing, as nearly 60 percent of Alzheimers caregivers report very high emotional stress.

What Is The Cost Of Alzheimers Disease On Caregivers

Caregivers of patients with Alzheimers and dementia shoulder a heavy load. The latest facts on Alzheimers show that caregivers spent over 18.5 billion hours of their own time last year, a contribution valued at nearly $234 billion, according to the Alzheimers Associations report. In addition, the report found that 83 percent of these caregiversmostly family and friendswere unpaid.

Similar to last year, nearly two-thirds of these caregivers were women. Among these caregivers, 41 percent made a combined household income of $50,000 or less. The total lifetime cost of care for someone with dementia was estimated at $350,174 in 2018, the Alzheimers Association said.

Projections For The Future

Total annual payments for health care, long-term care and hospice care for people with Alzheimer’s or other dementias are projected to increase from $355 billion in 2021 to more than $1.1 trillion in 2050 . This dramatic rise includes more than three-fold increases both in government spending under Medicare and Medicaid and in out-of-pocket spending.

6.6.1 Potential impact of changing the trajectory of Alzheimer’s disease

The Alzheimer’s Association commissioned a study of the potential cost savings of early diagnosis, assuming that 88% of individuals who will develop Alzheimer’s disease would be diagnosed in the MCI phase rather than the dementia phase or not at all. Approximately $7 trillion could be saved in medical and long-term care costs for individuals who were alive in 2018 and will develop Alzheimer’s disease. Cost savings were due to a smaller spike in costs immediately before and after diagnosis due to the diagnosis being made during the MCI phase rather than the dementia phase, which has higher costs, and lower medical and long-term care costs for individuals who have diagnosed and managed MCI and dementia compared with individuals with unmanaged MCI and dementia.

Alzheimers disease is not a normal part of aging. Memory problems are typically one of the first warning signs of Alzheimers disease and related dementias.

In addition to memory problems, someone with symptoms of Alzheimers disease may experience one or more of the following:

  • Memory loss that disrupts daily life, such as getting lost in a familiar place or repeating questions.
  • Trouble handling money and paying bills.
  • Difficulty completing familiar tasks at home, at work or at leisure.
  • Misplacing things and being unable to retrace steps to find them.
  • Changes in mood, personality, or behavior.
