Speak Up: Raise awareness. Talk to your neighbor. Tell your story. Dementia is not something that should be hidden or hushed, and neither is this disparity in dementia risk based on ethnicity.

Volunteer for Clinical Trials: We need more people from minority backgrounds to participate in clinical trials and other research studies. Many studies consist of populations with limited diversity. You can see a list of clinical trials here at TrialMatch, a service of the Alzheimer’s Association.

Go to Regular Screenings: Medicare coversat no cost to youan annual wellness exam, and this can include screening and testing of your cognition for symptoms of dementia. Be sure to tell your healthcare provider if you’re concerned about your memory . Early detection is very beneficial. It allows for the diagnosis and treatment of conditions that might cause memory loss and confusion but could be reversed if caught and treated. It also can allow for earlier treatment of Alzheimer’s and other types of dementia.

Advocate for Culturally Competent Services and Support Systems: Training in cultural competence helps ensure that healthcare services are provided in a way that honors diversity and encourages minority leadership and participation.

How Is Parkinsons Disease Dementia Diagnosed

No single test can diagnose Parkinsons disease dementia. Instead, doctors rely on a series or combination of tests and indicators.

Your neurologist will likely diagnose you with Parkinsons and then track your progression. They may monitor you for signs of dementia. As you get older, your risk for Parkinsons dementia increases.

Your doctor is more likely to conduct regular testing to monitor your cognitive functions, memory recall, and mental health.

How Many Canadians Live With Dementia Including Alzheimer’s Disease And How Many Are Newly Diagnosed Each Year

According to the most recent data available , more than 402,000 seniors are living with dementia in Canada . This represents a prevalence of 7.1%. About two-thirds of Canadian seniors living with dementia are women. Annually, there are approximately 76,000 new cases of dementia diagnosed in Canada. This represents an incidence of 14.3 new cases per 1,000 in the senior population . The incidence is higher among women than men. The prevalence and the incidence increase with age, as does the differential in prevalence and incidence estimates between men and women .

Data source: Public Health Agency of Canada, using Canadian Chronic Disease Surveillance System data files contributed by provinces and territories, April 2017.

Over a ten-year period , the age-standardized prevalence of dementia increased by 21.2%. During the same period, fluctuations in incidence have been observed. Drug data, one of the criteria used for case identification , became available in Alberta and Prince Edward Island in 20092010, which contributed to the temporary peak in incidence that year. Since then, incidence data suggest a decline .

Diagnosis Of Young Onset Dementia

  • On average, a person may see between two and five different consultants before a diagnosis is made
  • The average time to diagnosis is 4.4 years in younger people compared to 2.2 years for people aged over 65
  • In England in August 2018, the estimated dementia diagnosis rate for under 65s was 41%, compared to 68% for people aged over 65
  • Awareness amongst GPs is still relatively low and when people are younger, symptoms are often attributed to stress, anxiety, depression or menopause
  • People who are under 65 are more likely to be diagnosed with a genetically inherited form of dementia or a rarer dementia that can be difficult to recognise

Isnt Dementia Part Of Normal Aging

Alzheimers Disease 2020 Facts and Statistics

No, many older adults live their entire lives without developing dementia. Normal aging may include weakening muscles and bones, stiffening of arteries and vessels, and some age-related memory changes that may show as:

  • Occasionally misplacing car keys
  • Struggling to find a word but remembering it later
  • Forgetting the name of an acquaintance
  • Forgetting the most recent events

Normally, knowledge and experiences built over years, old memories, and language would stay intact.

Medications To Treat The Underlying Alzheimer’s Disease Process

Aducanumab is the first disease-modifying therapy approved by the FDA to treat Alzheimers disease. The medication helps to reduce amyloid deposits in the brain and may help slow the progression of Alzheimers, although it has not yet been shown to affect clinical outcomes such as progression of cognitive decline or dementia. A doctor or specialist will likely perform tests, such as a PET scan or analysis of cerebrospinal fluid, to look for evidence of amyloid plaques and help decide if the treatment is right for the patient.

Aducanumab was approved through the FDAs Accelerated Approval Program. This process requires an additional study after approval to confirm the anticipated clinical benefit. If the follow-up trial fails to verify clinical benefit, the FDA may withdraw approval of the drug. Results of the phase 4 clinical trial for aducanumab are expected to be available by early 2030.

Several other disease-modifying medications are being tested in people with mild cognitive impairment or early Alzheimers as potential treatments.

Prevalence By Age In The Uk

The biggest risk factor for dementia is age the older you are the more likely you are to develop the condition, but it is not an inevitable part of ageing. About two in 100 people aged between 65 to 69 have dementia, and this figure rises to one in five for those aged between 85 to 89.

Page last reviewed: 05/07/2018

It is a common misconception that dementia is a condition of older age, over 42,000 people under 65 years old have dementia in the UK.

Prevalence by age groups

Dementia Cases Expected To Triple By 2050 As World Population Ages

Across the globe, more than 35 million people are living with dementia, according to recent World Health Organization estimates.1 This number is expected to more than triple to reach 115 million by 2050 in the wake of world population aging.

Fueled by declines in fertility and increases in life expectancy, the share of the worlds population ages 65 and older is on track to jump from 8 percent today to nearly 17 percent in 2050, according to new U.S. Census Bureau population projections.

Dementia is a brain disease characterized by loss of memory, speech, reasoning, and other cognitive functions Alzheimers disease is the most common form likely accounting for 70 percent of all cases. The onset of dementia is devastating for individuals and their families, profoundly affecting the quality of life and taking a severe economic toll. Treating and caring for people with dementia currently costs more than US$600 billion per year worldwide , according to WHO. This estimate includes the cost of providing health and social care as well as the reduction or loss of income of people with dementia and their caregivers.

  • 1 in 3 seniors dies with Alzheimers or another dementia, killing more than breast and prostate cancer combined.
  • Alzheimers disease is listed as the sixth leading cause of death in the U.S. States, but it may cause more deaths than is recognized by official sources.
  • The COVID-19 pandemic caused Alzheimers deaths to increase by approximately 16% more than expected.
  • Deaths due to Alzheimers between 2000 and 2019 have more than doubled, increasing 145%. During the same time period, deaths from heart disease increased 7.3%.

What’s The Life Expectancy Of A Person With Dementia

Theres no easy way to answer this question. Dementia is an umbrella term that covers the many different types of underlying neurodegenerative diseases.

Each type of neurodegenerative disease has its own unique pattern and development in each person. Also, each person has a unique health profile. Some people may be relatively healthy and others may have several co-existing health issues. All of these factors play a role in the pace of decline in a person with dementia.

To answer more broadly, Alzheimers is the most common type of dementia. The average lifespan after the earliest symptoms is eight years. However, some people have lived as long as 20 years after an Alzheimers disease diagnosis.

Dementia Within The United States

Within the United States, there are at least 5 million people currently living with age-related dementias. As the population increases, these numbers are expected to rise. To put this into perspective, its estimated that one out of every six women and one out of every ten men, living past the age of 55 will develop dementia.

Although there are various forms of dementia, around 70 percent of cases are due to Alzheimers. Of the remaining cases, the second most common type is vascular dementia. Due to longer life expectancies and the baby boomer population, the percentage of Americans living with this disease will increase in the upcoming years.

Can Dementia Be Prevented

Although dementia cant be prevented, living a health-focused life might reduce risk factors for certain types of dementia.

Keeping blood vessels clear of cholesterol buildup, maintaining normal blood pressure, maintaining healthy blood sugar levels, staying at a healthy weight basically, staying as healthy as you can can keep your brain fueled with the oxygen and nutrients it needs to function at its highest possible level. Specific healthful steps you can take include:

  • Follow a Mediterranean diet, which is one filled with whole grains, vegetables, fruits, fish and shellfish, nuts, beans, olive oil and only limited amounts of red meats.
  • Exercise. Get at least 30 minutes of exercise most days of the week.
  • Keep your brain engaged. Solve puzzles, play word games and try other mentally stimulating activities. These activities may delay the start of dementia.
  • Stay socially active. Interact with people, discuss current events, and keep your mind, heart and soul engaged.

What Is Dementia And What Is Alzheimers Disease

The Growing Impact of Dementia on the Health of Populations » SPH ...

Dementia refers to a set of symptoms and signs associated with a progressive deterioration of cognitive functions that affects daily activities. It is caused by various brain diseases and injuries. Alzheimers disease is the most common cause of dementia. Vascular dementia, frontotemporal dementia, and Lewy body dementia constitute other common types. Symptoms of dementia can include memory loss, judgement and reasoning problems, and changes in behaviour, mood and communication abilities.Footnote 4

Why Do These Differences Exist

While genetic factors can increase the risk of Alzheimer’s, multiple studies have looked at race and genetics and have not found a clear correlation between these factors and dementia risk. Researchers have, however, found a connection between certain health conditions, race, and risk of cognitive impairment.

What Happens To A Persons Brain And Body As Dementia Gets Worse

Unfortunately, many types of dementia are conditions that worsen over time. When your brain doesnt get the nutrients and oxygen it needs, or junk blocks needed communication between the nerve cells of the brain, your brain tissue begins to die.

Alzheimers disease and other types of dementia usually begin with memory loss or lapses in judgment things that can be lived with for a while. As you lose more and more brain function, functions vital to life begin to be affected. Vital functions include breathing, digestion, heart rate and sleep.

In the late stages of dementia, people cant perform the tasks needed to keep their bodies alive. Brain damage and muscle weakness no longer allow even simple, needed movements. You cant communicate, walk, talk, control your bladder or bowels, feed yourself, or chew or swallow food without help.

When you cant care for yourself, move about, eat or drink enough to keep yourself hydrated and nourished, plus have mental decline, you leave yourself vulnerable to other illnesses. Pneumonia is one of these commonly seen illnesses in people with dementia. With a now frail body, a person may not be able to fight infections or even benefit from medication. The persons pain and discomfort may outweigh treatment options that can only offer a short-term benefit.

One In Seven Americans Age 71 And Older Has Some Type Of Dementia Nih

A new analysis suggests that about 3.4 million Americans age 71 and older one in seven people in that age group have dementia, and 2.4 million of them have Alzheimer’s disease . The study, supported by the National Institutes of Health , is the latest in a series of analyses attempting to assess the prevalence of dementia and AD, the most common form of dementia. Published online this week in Neuroepidemiology, the study is the first to estimate rates of dementia and AD using a nationally representative sample of older adults across the United States.

Brenda L. Plassman, Ph.D., of Duke University Medical Center, with Kenneth M. Langa, M.D., Ph.D., and David R. Weir, Ph.D., of the University of Michigan, Robert B. Wallace, Ph.D., of the University of Iowa, and others, conducted the analysis as part of the Aging, Demographics and Memory Study . ADAMS is a sub-study of the larger Health and Retirement Study , the leading resource for data on the combined health and economic circumstances of Americans over age 50. ADAMS and the HRS are sponsored by the National Institute on Aging, a component of NIH, under a cooperative agreement with the University of Michigan.

Despite the varied approaches and findings, however, NIA experts point out, the numbers of people with dementia, and Alzheimer’s specifically, will certainly increase until ways to delay the progression or prevent the dementia are found. Advancing age is the most common known risk factor for Alzheimer’s disease.

Whats The Difference Between Dementia And Alzheimers Disease

Number of people with dementia set to jump 40% by 2030, WHO says

Dementia is a description of the state of a persons mental function and not a specific disease. Dementia is an umbrella category describing mental decline thats severe enough to interfere with daily living.

There are many underlying causes of dementia, including Alzheimers disease and Parkinsons disease. Alzheimers disease is the most common underlying cause of dementia.

Icipating In Alzheimer’s Disease Clinical Trials

Everybody those with Alzheimers disease or MCI as well as healthy volunteers with or without a family history of Alzheimers may be able to take part in clinical trials and studies. Participants in Alzheimers clinical research help scientists learn how the brain changes in healthy aging and in Alzheimers. Currently, at least 270,000 volunteers are needed to participate in more than 250 active clinical trials and studies that are testing ways to understand, diagnose, treat, and prevent Alzheimers disease.

Volunteering for a clinical trial is one way to help in the fight against Alzheimers. Studies need participants of different ages, sexes, races, and ethnicities to ensure that results are meaningful for many people. To learn more about clinical trials, watch this video from NIH’s National Library of Medicine.

NIA leads the federal governments research efforts on Alzheimers. NIA-supported Alzheimers Disease Research Centers throughout the U.S. conduct a wide range of research, including studies of the causes, diagnosis, and management of the disease. NIA also sponsors the Alzheimers Clinical Trials Consortium, which is designed to accelerate and expand studies and therapies in Alzheimers and related dementias.

To learn more about Alzheimers clinical trials and studies:

  • Talk to your health care provider about local studies that may be right for you.

Dementia Affects A Persons Cognitive Abilities And Functioning Learn About How The Syndrome Is Caused Who It Affects And Why It Affects Them


Dementia is a clinical syndrome involving cognitive impairment that disrupts social and occupational functioning. Dementia can be caused by a variety of diseases, with Alzheimers disease being the most common form. Dementia is generally associated with old age, and there is a growing concern about a global epidemic of dementia. This is because of rising dementia trends in older people as well as increased life expectancy. Awareness of the facts and statistics regarding dementia can help with diagnosing and treating the condition.
