Life Expectancy And Alzheimers Disease
Alzheimer’s disease is the most common cause of dementia. Abnormal proteins cause steadily increasing brain damage. This initially affects thought and memory and remember and progressively causes failure of all body systems.
Alzheimers is typically diagnosed at the mild dementia stage when memory and planning problems start to affect daily life. The life expectancy for an individual with Alzheimer’s is usually between 8-12 years from diagnosis; however, someone fit and healthy on diagnosis could live considerably longer. In one American study, people lived from between one and twenty-six years after first spotting symptoms, so the variation is enormous.
Care In The Later Stages Of Dementia
There are medicines used in the early stages of dementia that manage some of the behavioural symptoms. In the later stages some of these medicines can do more harm than good causing severe side effects that can increase confusion and frailty. It also becomes harder to diagnose and manage some of the normal illnesses that older people get such as Urinary Tract Infections . UTIs can exaggerate some symptoms of dementia and increase confusion sometimes know as delirium.;
Pain is also something that can be present in the later stages of dementia, but can be harder to diagnose if the person isnt able to communicate it. For all of these reasons, its important to stay vigilant when looking after someone with dementia, and to talk to the GP if you are worried about anything.;
There are dementia living aids and products that can help you to care for someone living with dementia. Something like a simple dementia clock or personal alarm can make the world of difference to your life and the live of the person you care for.;
Recognising When Someone Is Reaching The End Of Their Life
Read about some of the signs that a person with dementia is nearing their death, and how you can support yourself as a carer, friend or relative.
It is important to know when a person with dementia is nearing the end of their life because it can help in giving them the right care. However it can be difficult to know when this time is.
This uncertainty can have a big impact on how the persons family feel, and may also affect how they feel themselves.
There are symptoms in the later stages of dementia that can suggest the person is reaching the final stage of their illness. These include:
- speech limited to single words or phrases that may not make sense,
- needing help with most everyday activities,
- eating less and having difficulties swallowing,
- bowel and bladder incontinence,
- being unable to walk or stand, problems sitting up and controlling the head, and becoming bed-bound.
It is likely that a person with dementia is nearing the end of their life if they have these symptoms, along with other problems such as frailty, infections that keep coming back, and pressure ulcers .;

The Long And Short Of Alzheimer’s Survival
Larson’s team found that several factors predict Alzheimer’s-disease survival:
- Women with Alzheimer’s disease live longer than men with Alzheimer’s disease.
- Unsteadiness in walking predicts shorter survival.
- Wandering behavior predicts shorter survival.
- Involuntary loss of urine predicts shorter survival.
- A poor score on tests of mental status predicts shorter survival.
- A rapid mental decline in the first year after diagnosis predicts shorter survival.
- Pre-existing heart disease or diabetes predicts shorter survival.
The researchers calculated the average number of years of life remaining to people when first diagnosed with Alzheimer’s disease. For each age, this is the number of years after which 50% of people remain alive. Compared with women and men without Alzheimer’s disease:
For women:
- After age 70, half of U.S. women live 15.7 more years. Half of women with Alzheimer’s disease live 8.0 more years.
- After age 75, half of U.S. women live 11.9 more years. Half of women with Alzheimer’s disease live 5.8 more years.
- After age 80, half of U.S. women live 8.6 more years. Half of women with Alzheimer’s disease live 5.3 more years.
- After age 85, half of U.S. women live 5.9 more years. Half of women with Alzheimer’s disease live 3.9 more years.
- After age 90, half of U.S. women live 3.9 more years. Half of women with Alzheimer’s disease live 2.1 more years.
For men:
Physical Difficulties In The Later Stages Of Dementia
The physical changes of late-stage dementia are partly why the person is likely to need much more support with daily living. At this stage they may:
- walk more slowly, with a shuffle and less steadily eventually they may spend more time in a chair or in bed
- be at increased risk of falls
- need a lot of help with eating and so lose weight
- have difficulty swallowing;
- be incontinent losing control of their bladder and bowels.
The persons reduced mobility, in particular, raises their chances of blood clots and infections. These can be very serious or even fatal so it is vital that the person is supported to be as mobile as they can.

How Long Will A Person With Dementia Live For
Whatever type of dementia a person has, their life expectancy is on average lower. This is why dementia is called a life-limiting condition. This can be very upsetting to think about.
However, its important to remember that, no matter how a persons dementia changes over time, there are ways to live well with the condition.
Good support can make a huge difference to the persons quality of life at all stages of dementia.
How long a person lives with dementia varies greatly from person to person. It depends on many factors, such as the ones listed on The progression and stages of dementia page.
Other factors include:
- how far dementia had progressed when the person was diagnosed
- what other serious health conditions the person with dementia has such as diabetes, cancer, or heart problems ;
- how old the person was when their symptoms started older people are more likely than younger people to have other health conditions that may lower their life expectancy. A person in their 90s who is diagnosed with dementia is more likely to die from other health problems before they reach the later stages;than is a person diagnosed in their 70s.
What Is The Average Life Expectancy
Life expectancy varies for each person with AD. The average life expectancy after diagnosis is eight to 10 years. In some cases, however, it can be as short as three years or as long as 20 years.
AD can go undiagnosed for several years, too. In fact, the average length of time between when symptoms begin and when an AD diagnosis is made is 2.8 years.

Dementia And Early Death
Across the globe, dementia rates are expected to double every 20 years for the foreseeable future, with an estimated 81 million cases by 2040.
It is clear from earlier studies that people with dementia have decreased survival compared with people without dementia. Even mild mental impairment linked to dementia is associated with an increase in death risk.
But the characteristics associated with mortality among patients with dementia have not been well understood.
There is general agreement that women with dementia tend to live slightly longer than men, but the impact of other characteristics, including education level, age at diagnosis, and marital status are less well known.
And many previous studies have been restricted to patients being treated for the disorder by a specialist or in a hospital setting, Brayne says.
“We wanted to see what is happening with the entire population, not just people who are treated for dementia,” she says.
Slightly over two-thirds of the people in the study who developed dementia were women, and the median age at dementia onset was 84 for women and 83 for men.
The median age at death was 90 for women and 87 for men. And average survival times varied from a high of 10.7 years for the youngest patients to a low of 3.8 years for the oldest .
As in other studies, dementia was associated with shorter survival, but the cognitive level among people with dementia did not appear to play a major role in death.
Each Persons Journey Is Different
Each person has a unique health history. This health history is directly related to how AD will affect them. Its helpful, however, to know the statistics about average life expectancy, as well as how lifestyle and age can alter that length of time.
If you are a caretaker or were recently diagnosed with AD, you can find empowerment and courage in knowing how the condition tends to progress. This allows you to plan with your family and caretakers.

Stage 6: Moderately Severe Dementia
When the patient begins to forget the names of their children, spouse, or primary caregivers, they are most likely entering stage 6 of dementia and will need full time care. In the sixth stage, patients are generally unaware of their surroundings, cannot recall recent events, and have skewed memories of their personal past. Caregivers and loved ones should watch for:

Alzheimer’s Disease: Predicting Survival
There’s still no way to give a precise answer. But new data paint a much sharper picture of how long a person with Alzheimer’s disease will survive — and how fast the disease will progress.
Memory Problems? Take the Alzheimer’s Quiz.
The information comes from a study of 521 Seattle residents aged 60 and older recently diagnosed with Alzheimer’s disease. Eric B. Larson, MD, MPH, director of the Center for Health Studies at the Group Health Cooperative, an HMO based in Washington state, led the study.
“Now you can give patients an idea of just how long, on average, they are going to live,” Larson tells WebMD. “And you can distinguish those with a worse prognosis from those with a better one.”
Earlier studies tended to look at hospitalized patients, who are much farther along in the course of their disease. Larson’s team found patients nearly as soon as they received their Alzheimer’s disease diagnosis. That makes the findings much more relevant to real life, says Neil Buckholtz, PhD, chief of the National Institute on Aging’s dementia branch.
“This study supports what we have been saying for a long time. Alzheimer’s survival is highly variable: five to 20 years,” Buckholtz tells WebMD. “President Reagan, for example, has survived for quite some time. It is quite variable for individuals.”
The findings appear in the April 6 issue of Annals of Internal Medicine.

What Does Age Have To Do With It
The age you are diagnosed with AD may have the greatest impact on your life expectancy. The earlier you are diagnosed, the longer you may live. Researchers at Johns Hopkins School of Public Health have discovered that the average survival time for people diagnosed at age 65 is 8.3 years. The average life expectancy for people diagnosed at age 90 is 3.4 years.

What Are The Early Signs Of Dementia
The onset of dementia is not obvious because the early signs can be vague and quite subtle. The early symptoms usually depend on the kind of dementia that one has and therefore can vary greatly from one person to the next.
Even though the signs can vary, there are some that are quite common and they include:
- Depression, apathy, and withdrawal
- Memory issues, especially when it comes to the most recent events
- Inability to handle the everyday tasks
At times, it is easy to miss to appreciate that the above symptoms could be an indication of something that is not right. Yet there are those who assume that the signs are normal and are associated with aging. It is also possible for one to develop the symptoms in a gradual manner and they may go unnoticed for quite some time.
People may not act even when they can tell that something is definitely wrong. It is important to have a checklist of all signs related to dementia and get the person the needed help when several of such signs are observed. It is important to get a more detailed assessment.
Memory loss and dementia: while it is normal to forget some things and remember later, persons with dementia tend to forget more frequently and they do not remember later.
Tasks: distractions can happen and you may forget to, say, serve one part of the family meal. For a person that has dementia, preparing the meal could be problematic and they may actually forget some of the steps that are involved.
Why Do Dementia Patients Stop Talking

Planning For The Alzheimer’s Future
For Larson, the many issues surrounding the care of a person with Alzheimer’s disease are personal as well as professional.
“When I started to see my father declining, it took a long time for my family to get comfortable with that,” he says. “The nice thing with this study is that everyone in it was within a year of diagnosis. This was like the real world. Now the family can say, ‘This is what is ahead. Let’s face it like anything else in life.'”
People with Alzheimer’s disease, Larson found, have about half the life expectancy of a same-age person without Alzheimer’s. Even so, many people with the disease have lots of life ahead of them.
“A fairly large number of people with Alzheimer’s disease are going to live a long time,” Larson says. “For example, one in four women diagnosed with Alzheimer’s disease will live for 10 more years. That is a lot of years of care to plan for.”
Make Everyday Tasks Easier
This “memory bench” is used by a person living with dementia to organize the things she needs for each day.
Many people with early-stage dementia continue to manage their everyday activities. But its important to look ahead to a time when performing daily tasks will be harder. The sooner you adopt new strategies to help you cope with changes, the more time you will have to adjust to them. Here are some tips:

Alzheimer’s Disease And Dementia Life Expectancy
Researchers in 2016 estimated that there were 43.8 million people in the world with Alzheimer’s disease or other forms of dementia27 million women and 16.8 million men. These numbers are growing rapidly. In fact, it’s expected to more than double to 100 million by 2050. Here’s what you should know about Alzheimer’s disease and dementia life expectancy.
Stage 5: Moderate Dementia
Patients in stage 5 need some assistance in order to carry out their daily lives. The main sign for stage 5 dementia is the inability to remember major details such as the name of a close family member or a home address. Patients may become disoriented about the time and place, have trouble making decisions, and forget basic information about themselves, such as a telephone number or address.
While moderate dementia can interfere with basic functioning, patients at this stage do not need assistance with basic functions such as using the bathroom or eating. Patients also still have the ability to remember their own names and generally the names of spouses and children.

Life Expectancy And Vascular Dementia
Repeated small strokes can damage the brain and cause vascular dementia. Its the second most common cause of the disease. The pattern of disease progression is different from the gradual deterioration of Alzheimers disease. The symptoms may be steady for a while, then suddenly get worse followed by a further period of stability. This reflects times when blood clots interrupt the blood supply to the brain, causing damage.
Because people with vascular dementia is linked to strokes, people affected often have other illnesses and may have worse general health. Research suggests that the average life expectancy is around four years. However, sudden or severe deterioration can happen when there is a further stroke.
The Start Of The Dying Process
As someones condition worsens and they get to within a few days or hours of dying, further changes are common. The person will often:
- deteriorate more quickly than before
- lose consciousness
- develop an irregular breathing pattern
- have cold hands and feet.
These changes are part of the dying process. Healthcare professionals can explain these changes so you understand what is happening. The person is often unaware of what is happening, and they should not be in pain or distress.
Medication can be used to treat the persons symptoms. If the person cant swallow, there are other ways of providing this, such as medication patches on the skin, small injections or syringe drivers . Speak to a GP or another health professional about this.
