Age When Diagnosis Is Determined
The age at diagnosis, too, is important because an older individual may already be frail and vulnerable to additional life-shortening accidents, diseases, or infections. Life expectancy after a diagnosis of dementia decreases with increasing age for example, an average person diagnosed with Alzheimers disease between ages 70 and 79 can expect to survive seven more years, while diagnosis after age 90 is associated with an expected survival of only 2.8 additional years.
Parkinsons Disease Symptoms: Life Expectancy
Even though Parkinsons disease is a serious, progressive condition, it is not considered a fatal illness. People who have Parkinsons disease usually have the same average life expectancy as people without the disease.
But when the disease is in its advanced stages, Parkinsons symptoms can lead to life-threatening complications, including:
- Falls that lead to fractured bones
Thinking about the progression of Parkinsons disease can be frightening. But proper treatments can help you live a full, productive life for years to come. And researchers hope to one day find ways to halt the progression of Parkinsons and restore lost functioning.

The Role Of Dementia And Age
Dementia also plays an important role in survival with Parkinsons. By the end of the above study, nearly 70% of the population with Parkinsons had been diagnosed with dementia, and those with dementia had a lower survival rate as compared to those without.
This means that those with dementia were more likely to die during the six-year period than those without dementia. In addition, scientific studies have shown that increasing age is linked to an increased risk of death.
Its important to remember that how a persons Parkinsons disease manifests and progresses is variable, and a persons neurologist cannot accurately predict individual life expectancy.
There are simply no key signs or symptoms that allow a healthcare provider to perfectly predict longevity. An older age and the presence of dementia are simply associated with an increased risk of dying.

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 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.

Stage : Normal Outward Behavior
Alzheimerâs disease usually starts silently, with brain changes that begin years before anyone notices a problem. When your loved one is in this early phase, they won’t have any symptoms that you can spot. Only a PET scan, an imaging test that shows how the brain is working, can reveal whether they have Alzheimer’s.
As they move into the next six stages, your friend or relative with Alzheimer’s will see more and more changes in their thinking and reasoning.
Does Parkinsons Affect Your Lifespan
Parkinsons research and treatments have come a long way, so much so that the average life span of a person with Parkinsons is the same or near the same as someone without Parkinsons disease. However, the lifespan of a person can vary widely based upon that persons health choices, such as their diet, exercise routine, if they have a history of smoking and many other factors. So, for most people with Parkinsons, as long as you focus on managing your Parkinsons disease and make healthy choices your lifespan should not be shortened.

Changes In Mood Emotions And Perceptions
Changes in mood remain in the later stages of dementia. Depression and apathy are particularly common.
Delusions and hallucinations are most common in the late stage of dementia. They are not always distressing but they can explain some changes in behaviour because the persons perception of reality is altered.
People with later stage dementia often respond more to senses than words. They may like listening to songs or enjoy textures. For example, they may like the feel of different types of material.
Life Expectancy For Other Forms Of Dementia
Although Alzheimers disease is our focus here, a discussion of survival should consider other dementias as well. Survival after a diagnosis of Lewy body dementia is significantly shorter than survival after a diagnosis of Alzheimers disease. Survival lengths after a diagnosis of vascular dementia or frontotemporal dementia are intermediate. Compared to dementia, a diagnosis of mild cognitive impairment is associated with a smaller reduction in life expectancy, and in many cases does not lead to Alzheimers disease and dementia.
Life expectancy after a diagnosis of Alzheimers disease varies from person to person. In the case of Genevieves mother, a white woman of age 75 at the time of her diagnosis, I estimated her expected survival to be around 6.7 years. This ballpark figure might prove correct or not since it is an estimate based on a population rather than a certainty for this individual. Having a general idea of expected survival assisted Genevieves family in facing the most probable future, planning, and valuing the preciousness of each remaining day.

Learn about the many factors that affect average life expectancy after a diagnosis of Alzheimers disease.
Genevieve* asked if she could speak privately with me after her mothers evaluation session and diagnosis of Alzheimers disease. I didnt want to ask this in front of her, she said, but my brother and I want to knowhow much time does she have left? Life expectancy after a diagnosis of Alzheimers disease, while uncomfortable to discuss, can be important information for patients and families to have. Ill describe what we know about this topic, and some of the factors that affect survival with and without dementia. Please bear in mind that this information is based on statistical averages, and there can be individual variations in the disease and a person’s resilience to it.
*The name and details were changed to protect privacy.
The most honest answer to Genevieves question may be, It depends. After a diagnosis of Alzheimers disease or another dementia, people can live for months to years, depending on individual circumstances. Its been shown that factors like age, race, genetics, health background, socioeconomic status, and education influence the life expectancy of large numbers of people with Alzheimers. However, every individuals disease is different, and may not follow the average course.
Caring For Your Health With Parkinsons Disease
In addition to caring for your Parkinsons health, it is also important to care for your overall health. This means visiting your primary care physician periodically for preventive care like the annual flu shot and cancer screeningsfor example, a mammogram for breast cancer screening and a colonoscopy for colon cancer screening.
A primary care physician can also evaluate for risk factors related to heart attacks and strokes, and provide counseling on exercise, smoking, alcohol use, depression, or other mental health concerns. Regular visits to your primary care physician or neurologist will also allow them to catch bacterial infections like urinary tract infections before they get serious.

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.

People With Dementia Have Shortened Life Expectancies
People with and other forms of live, on average, about four and a half years after their condition is diagnosed. This is based mainly on people in their 80s and 90s who have recently developed Alzheimers. In general, people with Alzheimers have about one-half the life expectancy, after , than people who do not have Alzheimers. The present findings are from a large collaborative study group in the United Kingdom. The findings appeared in the British Medical Journal.
The findings may help those who care for a loved one with Alzheimers disease to better plan for the future. The results highlight that dementia is a chronic condition, and that people with Alzheimers will likely need care for a number of years after their diagnosis. At the same time, the average survival time is under five years, with wide variations depending on age and physical condition at the time of diagnosis.
Researchers at the University of Cambridge followed more than 13,000 men and women, aged 65 and up, for 14 years. During that time, 438 of the study participants developed Alzheimers disease or , and more than 80 percent of those with dementia died.
The median age at death was 90 for women and 87 for men. Average survival times varied widely, however, depending on the age at diagnosis. Those who were diagnosed at a younger age, from 65 to 69, lived an average of 10.7 years after diagnsosis. Those diagnosed in their 90s, on the other hand, lived an average of 3.8 years.
A Growing Problem
Can Alzheimer’s Disease Be Prevented
As the exact cause of Alzheimer’s disease is not clear, there’s no known way to prevent the condition.
But there are things you can do that may reduce your risk or delay the onset of dementia, such as:
- staying physically fit and mentally active
These measures have other health benefits, such as lowering your risk of cardiovascular disease and improving your overall mental health.

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.
Causes Of Parkinsons Disease
Parkinsons disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinsons disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.

Beyond Memory Loss: How To Handle The Other Symptoms Of Alzheimer’s
There is a lot of talk about the emotional pain patients and caregivers suffer when a loved one loses memories to Alzheimers. But what about the other symptoms? Here are tips from a Johns Hopkins expert on what to watch for and how to manage.
#TomorrowsDiscoveries: From Dysfunctional Cells to Disease Dr. Rong Li
Dr. Li and her team investigate how cells consolidate their damaged proteins and prevent them from spreading freely, in order to understand how to better treat diseases such as Alzheimers and ALS. Another of their interests is how chromosomes are divided up when one cell becomes two. Learning more about how the process can go wrong could lend insight into cancer development.
Stage : Moderately Severe Decline
Your loved one might start to lose track of where they are and what time it is. They might have trouble remembering their address, phone number, or where they went to school. They could get confused about what kind of clothes to wear for the day or season.
You can help by laying out their clothing in the morning. It can help them dress by themselves and keep a sense of independence.
If they repeat the same question, answer with an even, reassuring voice. They might be asking the question less to get an answer and more to just know you’re there.
Even if your loved one can’t remember facts and details, they might still be able to tell a story. Invite them to use their imagination at those times.

Dementia is a life-limiting condition and there is information about later-stage dementia and life expectancy on this page. Some people may find this upsetting and difficult to think about.
For more general information about the different stages of dementia, see The progression and stages of dementia page.
By the later stage of dementia, the condition will have a severe impact on most aspects of a persons life. The person will eventually need full-time care and support with daily living and personal care, such as eating, washing and dressing. This support can be provided by care at home but is more often given in a care home setting.
Symptoms of all kinds are likely to cause the person considerable difficulties in this stage, but altered perception and physical problems are often the most noticeable. By the late stage, the symptoms of all types of dementia become very similar.
The later stage of dementia tends to be the shortest. On average it lasts about one to two years.

Certain medications can also affect memory. A lack of sleep and an impaired thyroid function can negatively affect memory. Some of these conditions can also lead to a decreased ability to remember events. In addition to these, natural aging can affect brain function, and may lead to a slowdown in memory. Although this symptom does not necessarily mean that youre losing your memory, it could indicate a problem with your cognitive ability. If you are suffering from either, a medical evaluation is necessary to determine if youre suffering from memory loss. Average Life Expectancy After Alzheimers Diagnosis
In addition to aging, medications can affect memory. Certain antidepressants, anxiety medications, and sleep disorders can all affect memory. A persons mental health can also contribute to memory problems. In some cases, a persons mental state may be affected by the medication they are taking. Some untreated medical conditions can lead to deterioration of the brain and affect the ability to learn and remember. It is also important to see a medical professional if your symptoms persist even after youve stopped taking certain medications.
