2016 Alzheimer’s Statistics

Alzheimer’s Worldwide

About 45 million people have Alzheimer’s or a related dementia at the end of 2015.

Only 1-in-4 people with Alzheimer’s disease have been diagnosed.

Alzheimer’s is most common in Western Europe.

Alzheimer’s and other dementias are the top cause for disabilities.


The Cost of Alzheimer’s Care

1. The global cost of Alzheimer’s is estimated to be $605 billion, equivalent to 1% of the entire world’s gross domestic product.

2. Medicare and Medicaid are expected to pay $154 billion in 2015 for health care, long-term care and hospice for people with Alzheimer’s and other dementias.

3. Aggregate Cost of Care by Payer for Americans Age 65 and Older with Alzheimer‘s Disease and Other Dementias: Medicare $113 Billion, Medicaid $41 Billion, Out of pocket $44 Billion, Other $29 Billion.

Alzheimer’s in the United States

1-in-9 Americans over 65 has Alzheimer’s disease. (Alzheimer’s Association)

When the first wave of baby boomers reaches age 85 (in 2031), it is projected that more than 3 million people age 85 and older will have Alzheimer’s. (Alzheimer’s Association)

One-third of Americans over age 85 are afflicted with the illness. (Alzheimer’s Association)

5.3 million Americans are living with Alzheimer’s disease. (Alzheimer’s Association)

Unless a cure is found, more than 16 million Americans will have the disease by 2050. (Alzheimer’s Association)

Alzheimer’s disease is the 6th leading cause of death in America. (Centers for Disease Control)

1-in-3 seniors die with Alzheimer’s or another kind of dementia. (Centers for Disease Control)

Typical life expectancy after an Alzheimer’s diagnosis is 4-to-8 years. (Alzheimer’s Association)

In 2016, the 85-years-and-older population includes about 2 million people with Alzheimer’s disease, or 40% of all people with Alzheimer’s age 65 and older. (Alzheimer’s Association)

By 2050, there could be as many as 7 million people age 85 and older with Alzheimer’s disease, accounting for half (51%) of all people 65 and older with Alzheimer’s. (Alzheimer’s Association)

Proportion of People With Alzheimer’s Disease in the United States by Age: (Alzheimer’s Association)

85+ years – 38%, 75-84 years, 44%, 65-74 years, 15%, less than 65 years, 4%

Who Gets Alzheimer’s Disease?

2-in-3 people with Alzheimer’s are women.

African Americans and Hispanic Americans are more likely to develop Alzheimer’s than Caucasian Americans.


More than 40% of family caregivers report that the emotional stress of their role is high or very high. (Alzheimer’s Disease International)

In 2014, Alzheimer’s and dementia caregivers had $9.7 billion in additional health care costs of their own. (Alzheimer’s Association)

In the 2009 NAC/AARP survey, caregivers most likely to indicate stress were women, older, residing with the care recipient, and Caucasian or Hispanic. In addition, these caregivers often believed there was no choice in taking on the role of caregiver. (Alzheimer’s Association)

People with Alzheimer’s disease are hospitalized three times more often than seniors without Alzheimer’s. (Alzheimer’s Association)

74% of caregivers of people with Alzheimer’s disease and other dementias reported that they were “somewhat concerned” to “very concerned” about maintaining their own health since becoming a caregiver. (Alzheimer’s Association)

68% of nursing home residents have cognitive impairment from Alzheimer’s disease or a related disorder. (Alzheimer’s Association)

52% of assisted living facilities provide dedicated memory care for residents with Alzheimer’s disease. (Alzheimer’s Association)

In 2014, more than 15 million Americans provided more than 17.9 billion hours of unpaid care for people with Alzheimer’s disease and other dementia’s. (Alzheimer’s Association)

More than 15 million Americans provide unpaid care for people with Alzheimer’s disease and other dementia’s. (Alzheimer’s Association)

Memory loss is one of the symptoms of Alzheimer’s but still it is not the only one. The memory loss at Alzheimer’s is rather specific – the patients not just lose their memory, their brain is being destructed. This causes not just forgetfulness but inability to control their body, etc.


Alzheimer’s disease is rather dangerous. But it is not the reason for panic. Be attentive to first symptoms and try to prevent it. But if it is a bit late to prevent try to slow down increasing brain activity, helping your body to become healthy. Right now it is impossible to cure this disease, but there are a lot ways to prevent and slow down it. Still APCO is working hard on the cure.


1. Advancing age was the first risk factor for this disease till 2015.

In 2015 there were registered 2 patients at the age a bit higher than 25. Most of all Alzheimer’s still is diagnosed at advancing age, but the situation seems to change.

2. The most dangerous one is the decrease of the brain activity.

The more you train your brain in the right way the less is the risk to get Alzheimer’s.

Healthy life style is helpful also.

3. Genetics.

Those who have a parent, brother, sister or child with Alzheimer’s are more likely to develop the disease. The risk increases the more members have the illness. When diseases tend to run in families, either heredity (genetics) or environmental factors, or both, may play a role.

Talking about genetics as a science, scientists concluded that IL1-RAP gene is the most important and cause Alzheimer’s according to the up-to-date research results.

Earlier they found out that here were two types of genes that could play a role in affecting — risk genes and deterministic genes. Alzheimer's genes have been found in both categories.

a - Risk genes increase the likelihood of developing a disease. The risk gene with the strongest influence is called apolipoprotein E-e4 (APOE-e4). Scientists estimate that APOE-e4 may be a factor in 20 to 25 percent of Alzheimer's cases.

b - APOE-e4 is one of three common forms of the APOE gene; the others are APOE-e2 and APOE-e3. Everyone inherits a copy of some form of APOE from each parent. Those who inherit APOE-e4 from one parent have an increased risk of Alzheimer’s. Those who inherit APOE-e4 from both parents have an even higher risk, but not a certainty. Scientists are not yet certain how APOE-e4 increases risk. In addition to raising risk, APOE-e4 may tend to make Alzheimer's symptoms appear at a younger age than usual.

c - Deterministic genes directly cause a disease, guaranteeing that anyone who inherits them will develop Alzheimer’s: amyloid precursor protein (APP), presenilin-1 (PS-1) and presenilin-2 (PS-2).

d - When Alzheimer’s disease is caused by these deterministic variations, it is called “autosomal dominant Alzheimer’s disease (ADAD)” or “familial Alzheimer’s disease,” and many family members in multiple generations are affected. Symptoms nearly always develop before age 60, and may appear as early as a person's 30s or 40s. Deterministic Alzheimer's variations have been found in only a few hundred extended families worldwide. True familial Alzheimer’s accounts for less than 5 percent of cases.

4. Head injuries.

Head injuries and Alzheimer’s are strongly connected as there were incidents when the Alzheimer’s showed after violence, transportation accidents, construction, and sports.

5. Heart & body.

All components of our body are interrelated so blood pressure, heart disease, stroke, diabetes and high cholesterol can be also risk factor for Alzheimer’s.

IV. FIRST symptoms

Mild forgetfulness. Forgetting the names and recent events.

Figuring the same question many times.

Repeating the same story word for word.

Difficult to pay in the store.

Possible to get lost in a familiar environment.

Neglecting hygiene procedures. Patients no longer monitor the cleanliness of their clothes and their homes.

Usage of the words similar in sounding but different in meaning.

Difficultness with concentration.

Neglecting new things or minor changes.

Quickly lost of interest and becoming irritable and aggressive for no reason.

Forgetting to eat or the fact that already had dinner. Always choosing only one type of food. Not experiencing the feeling of satiety.

Often losing things.
