Alzheimer’s Stages Life Expectancy The 7 Stages Of Alzheimer’s Disease
With early diagnosis and adequate care, the average lifespan of those with Alzheimer’s disease increases. If you suspect that you or your loved ones may be at risk of having Alzheimer’s disease, please get in touch with a medical professional!
The life expectancy of those with Alzheimer’s disease may greatly vary depending on the age, general health condition, early diagnosis, and treatment in early stages. Nevertheless, we can roughly answer the question: “What is the life expectancy of someone with Alzheimer’s?” with general estimations, depending on the stage of the disease’s development .
Life expectancy in Alzheimer’s stages varies make sure to consult with a medical professional for full clinical evaluation. Although Alzheimer’s does shorten life expectancy, the quality of life of those who have the disease can be significantly improved by adequate care and attention.
Improving Quality Of Life
In the early stages of Alzheimer’s disease, cognitive impairment is not the only determinant of quality of life. While you can’t change factors such as age at diagnosis or gender, research shows that the care that a person receives impacts life expectancy. Be sure that you explore options when it comes to creating a care plan for a loved one diagnosed with Alzheimer’s disease and take advantage of any support groups or other resources that may help.
Recent research indicates that factors associated with a lower quality of life for Alzheimer’s disease patients include patient depression and anxiety, and having to take multiple medicinesindicative of having other disease states to manage. Efforts to improve the quality of life for patients should include an assessment of these factors so they can be effectively addressed. Caregiver quality of life should also be assessed, especially as the disease progresses and the burden of caregiving increases.
The extent to which a person with the disease can maintain his or her social relationships can also play a large role. Patients should talk with their doctor or a psychologist for strategies to cope with social situations.
In addition, maintaining household responsibilities for as long as able can help improve the quality of life. In later stages, a patient’s needs may change, and it is important for a caregiver to know how to care for themselves in addition to their loved one.
Does The Type Of Dementia Affect Life Expectancy
The type of dementia a person has can also affect how long they live with dementia. These figures for the number of years a person may live after a diagnosis are just averages and some people live longer than this.
This information may be upsetting to read and think about but it is very important to remember that, with the right support, people with dementia can live well at all stages.

Check Their Advance Care Plan
You should find out if the person has an advance care plan. This document may record their preferences about the care theyd like to receive, including what they want to happen, what they do not want to happen and who they want to speak on their behalf. It may include an advance statement or an advance decision. We have information on planning ahead for patients and their families, which you might find useful.
Comparison With Other Studies
Studies that estimate life expectancy with and without Alzheimers dementia according to adherence to lifestyle factors seem to be lacking. Most of the studies in the literature have focused on calculating the overall life expectancy lived with dementia, and only a few studies have examined the role of risk factors, such as educational attainment or genetic risk . Specifically, a study in the US using a Markov model to estimate life expectancy with and without dementia showed that people with higher educational attainment have an increased life expectancy without dementia and a greater percentage of life expectancy lived without dementia. A similar investigation from Europe confirmed that people with primary education spent more time of their remaining life expectancy with dementia than those with higher education. Additionally, this study showed that the presence of the APOE 4 allele was associated with an increased number of years living with dementia in women and men. In this study, we controlled regression models for education and the APOE 4 allele and focused our investigation on modifiable risk factors, such as lifestyle factors.

Overview Of Alzheimer’s Disease
Alzheimer’s disease is a chronic and progressive brain disorder, accounting for 6080% of the cases in patients with dementia. Those with Alzheimer’s disease gradually display symptoms such as:
- Memory decline
- Difficulty with planning and with problem-solving
- Difficulty in completing everyday tasks
- Difficulty in concentrating and bouts of confusion
- Difficulty in comprehending spatial relationships
- Trouble with making reasonable judgments
- Difficulty in coping with unfamiliar situations
- Changes in personality and mood and
- Impulsive behavior and aggressiveness.
These symptoms are thought to be caused by changes in the brain. These changes include the development of amyloid plaques and abnormal accumulations of a protein, which disrupts connections between brain cells. Over time, brain cells die, and parts of the brain start to shrink. These changes in the brain may appear long before the diagnosis and usually begin in the hippocampus, a part of the brain that’s involved in learning and memory, hence why memory decline is one of the first displayed symptoms. Unfortunately, the life expectancy of those who develop Alzheimer’s disease is shortened. Keep on reading to find out what the seven stages of Alzheimer’s disease are and how our Alzheimer’s life expectancy calculator works.
The most significant known risk factor for developing Alzheimers disease is aging.
Risk Of Dementia And Death
Of all 10,348 participants, 521 were diagnosed with dementia at baseline. During 120,673 person-years of follow-up , 1,666 participants developed dementia, and 6,150 died. Women were at higher risk of dementia than men : 1.05, 1.36), while they were at lower risk of death . Table shows the sex-stratified associations of educational attainment and APOE genotype with risk of dementia and mortality. Higher educational attainment was associated with a lower risk of dementia and death among nondemented individuals, and relative risk estimates for dementia thereby exceeded those of mortality . The presence of 1 or 2 APOE-4 alleles was associated with an increased risk of dementia as well as a more modest increase in risk of death in individuals without but not with dementia .

Evidence That Life Expectancy Calculators For Dementia Actually Work
It turns out that the length of time a person has before needing full-time care, before moving into a care community, and before dying can all be predicted somewhat accurately. This information, though not definitive, can help families get a general understanding of how to plan for the future and what to expect as the disease progresses.
In a study conducted at the department of neurology in Columbia University, groups of people with mild Alzheimers were followed for 10 years and assessed semiannually. Data from these assessments were plugged into a complicated algorithm. The people studied were tested for the following:
Mental status score Cognition and function Motor skills Psychology and behavior Basic demographic information
Other experiments have yielded similar results. A University of Kentucky study analyzed the records of more than 1,200 people with dementia and found that it was possible to accurately predict their life expectancy. Researchers looked at many variables including family history and medical problems like high blood pressure and heart disease, and ultimately realized it came down to three things:
age when the first symptoms appeared gender how impaired someone was when diagnosis was first made

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.
Standard Protocol Approvals Registrations And Patient Consents
Ethics permission for this study was obtained from the regional human ethics committee of Stockholm . Quality registries such as SveDem are considered an important part of the development and improvement of health and social care in Sweden. Each patient has to be informed about the registration and has the right to decline participation. Written consent is not required however, each patient has the right to obtain a copy of the information that is registered if requested and to withdraw consent.

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.
Why Knowing Life Expectancy Is Useful
Knowing what to expect, including life expectancy helps with planning. Someone predicted to survive for five or six years, as opposed to two years, will want to make more extensive plans, including getting an estate in order, activity planning, and budget. Knowing how quickly the disease is expected to progress symptomatically can impact care decisions. If the disease is predicted to come on very quickly, for example, then skipping traditional assisted living and looking into memory care or a nursing home might be the best option.
Knowing when full-time care becomes a requirement, either at-home or in a memory care residence, is especially useful given the high cost of care. It is estimated that 50% of nursing home residents have some level of dementia and over 60% of nursing home residents care is paid for by Medicaid. Medicaid eligibility is complicated, and families can spend up to 5 years waiting for a loved one with dementia to become Medicaid-eligible. Therefore, knowing how soon care is required can make a huge financial difference.

How To Get A Better Idea Of Life Expectancy For Your Individual Situation
Whilst every person is different, and every dementia journey is different, if you want more clarity about how long you, or your loved one might live, studies suggest that the main factors to consider are:
1. Age 2. General health when diagnosed .3. Which form of dementia they have .4. How much they can still do for themselves day to day. Experts call this functional ability, and it seems to matter more than cognitive ability. In other words, people who continue to try doing things for themselves, even if their dementia is quite advanced, tend to live longer than those who stop.
*Other factors, such as whether you are married, living at home or your level of education dont seem to have an impact.
Main Findings And Interpretation
This study is one of the largest that examined the trajectories of persons with dementia in linked routine nationally representative administrative databases. Until now, reliable estimates from high-quality studies are scarce, but are important to help to inform patients and their families about probable care trajectories and policymakers to optimize the allocation of resources.

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.
Causes Of Vascular Dementia
Vascular dementia is caused by reduced blood flow to the brain, which damages and eventually kills brain cells.
This can happen as a result of:
- narrowing and blockage of the small blood vessels inside the brain
- a single stroke, where the blood supply to part of the brain is suddenly cut off
- lots of “mini strokes” that cause tiny but widespread damage to the brain
In many cases, these problems are linked to underlying conditions, such as high blood pressure and diabetes, and lifestyle factors, such as smoking and being overweight.
Tackling these might reduce your risk of vascular dementia in later life, although it’s not yet clear exactly how much your risk of dementia can be reduced.

When Should I Ask For Support
Supporting people with dementia at the end of their life requires a team approach. Often, there will be many people involved in the persons care at the end of their life. Good communication and information sharing helps to ensure the person receives the care they need.
If youre unsure about anything or have any concerns seek advice from a colleague, manager or another health care professional.
There may be certain professionals who can advise on specific issues. These may include a GP, district nurses, social workers, other care staff and specialists.
Living Well With Dementia
Talking about death and dementia is difficult and distressing. The statistics can seem scary. However, each individual is different. People can live well with dementia, and you can still look forward to times of joy and togetherness. Professional home carers can help to ease the burden for family carers, supporting your loved one to continue living in their own home in comfort and safety.

Life Expectancy And Alzheimers Disease
Alzheimers 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 Alzheimers 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.
