Life Expectancy For Alzheimer Patients

The Later Stage Of Dementia The Later Stage Of Dementia

People with later-stage dementia will eventually need full-time care and support with daily living and personal care, such as eating, washing and dressing. Whatever kind of dementia a person has, their life expectancy is on average lower.

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.

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.

Life Expectancy In Ad Compared With The General Population

The mean survival time after the estimated onset of AD symptoms was 8.83 years and was shorter in males than in females . The mean time after the start of ChEI treatment to death was 5.73 years , and was also significantly shorter in males compared with females . Table 3 shows the mean length of life for the male and female SATS cohorts divided into 5-year age groups at the start of ChEI therapy, low versus high level of education, APOE genotype, early versus late onset of AD, and mild versus moderate stage. Life expectancy for the gender- and age-matched general population is also presented, together with the AD patients’ estimated decrease in length of life for each cohort.

Table 3

Life expectancy after the start of ChEI therapy in AD compared with the gender- and age-matched general population

There was a trend towards significance for participants with a lower education level to have a longer survival time after baseline compared with individuals with a higher education level. Patients with an early onset of AD showed a longer time from the baseline to death than those with late-onset AD . The individuals in the mild stage of AD had a longer survival time compared with those in the moderate stage . No significant difference in length of life from the start of ChEI treatment was observed among the APOE genotypes.

Facts About Alzheimer Disease

Alzheimer disease is becoming more common as the general population gets older and lives longer. Alzheimer disease usually affects people older than 65. A small number of people have early-onset Alzheimer disease, which starts when they are in their 30s or 40s.

People live for an average of 8 years after their symptoms appear. But the disease can progress quickly in some people and slowly in others. Some people live as long as 20 years with the disease.

No one knows what causes Alzheimer disease. Genes, environment, lifestyle, and overall health may all play a role.

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 : Moderate Decline

During this period, the problems in thinking and reasoning that you noticed in stage 3 get more obvious, and new issues appear. Your friend or family member might:

• Forget details about themselves
• Have trouble putting the right date and amount on a check
• Forget what month or season it is
• Have trouble cooking meals or even ordering from a menu
• Struggle to use the telephone
• Not understand what is said to them
• Struggle to do tasks with multiple steps like cleaning the house.

You can help with everyday chores and their safety. Make sure they aren’t driving anymore, and that no one tries to take advantage of them financially.

Stage : Very Severe Decline

Many basic abilities in a person with Alzheimer’s, such as eating, walking, and sitting up, fade during this period. You can stay involved by feeding your loved one with soft, easy-to-swallow food, helping them use a spoon, and making sure they drink. This is important, as many people at this stage can no longer tell when they’re thirsty.

In this stage, people with Alzheimer’s disease need a lot of help from caregivers. Many families find that, as much as they may want to, they can no longer take care of their loved one at home. If thatâs you, look into facilities such as nursing homes that provide professional care day and night.

When someone nears the end of their life, hospice may be a good option. That doesn’t necessarily mean moving them to another location. Hospice care can happen anywhere. Itâs a team approach that focuses on comfort, pain management and other medical needs, emotional concerns, and spiritual support for the person and their family.

What Are Symptoms Of Alzheimer’s

Symptoms of Alzheimers are usually mild to start, and slowly and progressively worsen.

Early symptoms of mild Alzheimers disease may include:

• Forgetfulness/memory loss
• Problems with language, such as being unable to find the right words for things
• Difficulty with everyday tasks such as paying bills or balancing a checkbook
• Wandering and getting lost in familiar places

As Alzheimers disease progresses, symptoms of moderate Alzheimers may include:

• Increased memory loss and confusion
• Inability to learn new things
• Difficulty with language and problems reading, writing, and working with numbers
• Problems with logical thinking
• Inability to recognize family and friends
• Shortened attention span
• Difficulty coping with new situations
• Episodes of anger or aggression
• Difficulty performing tasks that require several steps, such as getting dressed
• Impulsive behaviors
• Restlessness, agitation, anxiety, tearfulness, wandering
• Repeating words or movements, muscle twitches
• Loss of interest in surroundings
• Seeing things that aren’t there
• Believing things that aren’t true

Symptoms of severe Alzheimers disease may include:

• Inability to eat, bathe, dress, or perform other everyday tasks
• Inability to communicate

How Does Alzheimer’s Lead To Death

Alzheimers disease is a degenerative brain disorder in which brain cells destruct. The condition results in a decline in memory, behavior, and mental capabilities.

It is not Alzheimer’s disease that kills a person. Death typically results from an inability to carry out routine activities, such as eating, taking care while walking, visiting the bathroom and toilet. This inability to take care of oneself makes the affected person fall prey to problems, such as malnutrition, dehydration, falls, and infections , which lead to death.

Pneumonia is a common cause of death in people with Alzheimers disease. Problems while swallowing make ingested food particles enter the respiratory tract and the lungs instead of the esophagus. This ingested food causes pneumonia in the lungs.

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.

The Later Stages Of Dementia

It is important to remember that not everyone living with dementia will want to know what is ahead of them. However, if youre caring for someone living with dementia, it is useful to know about the later stages of the disease so you can make decisions about future care options.

In the later stages of dementia, symptoms such as poor memory, confusion and other forms of cognitive impairment are joined by more physical symptoms.

Dementia is an illness of progressive cell damage. It starts in the parts of the brain that deal with memory and slowly moves to parts of the brain that control other functions. Sadly, this will eventually cause major organs to stop working. Below you can find a summary of some of the things you can expect when caring for someone in the later stages of dementia.

Life Expectancy By Stage Of The Disease

The average number of years a person lives with Alzheimers disease is about 10. Keep in mind, however, that theres a gap between when symptoms begin and when a diagnosis is actually sought. The first symptoms of Alzheimers diseaseforgetting names, misplacing items, difficulty concentrating at work or performing simple tasksarrive an average of almost three years before the diagnosis is made.

The scale most commonly used by health professionals for the stages of dementia is the Global Deterioration Scale , also called the Reisberg Scale. The table below shows a patients average life expectancy by the stage of dementia. These are averages based on studies of large numbers of Alzheimers patients.

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.

Mortality And Life Expectancy

Using the 12-digit personal identity number assigned to each resident in Sweden, all 1,258 SATS patients were investigated with the help of the Swedish population register regarding whether they were still alive on December 31, 2012. If not, the date of death was recorded.

The probable remaining length of life for each participant according to their gender and age at baseline was obtained from Statistics Sweden, based on life tables for the periods of 1993-1997 , 1998-2002 , 2003-2007 , and 2008-2012 , depending on the individual’s year of inclusion in the SATS. The patient’s actual survival time was compared with his/her expected life span relative to the gender- and age-matched general population. This unique approach allows the estimation of the decrease in the mean number of years of life span in association with different risk factors such as age at diagnosis, APOE genotype, and stages of AD.

Variables Impacting Life Expectancy Calculations

Gender. Men dont live as long with Alzheimers as women. A study of more than 500 people diagnosed with Alzheimers disease between 1987 and 1996 found that women with Alzheimers live, on average, 20% longer than men. Age. Someone diagnosed at 65 lives an average of about eight years, while someone over 90 who gets a diagnosis typically lives about three-and-a-half more years. Strength of Symptoms at Diagnosis. If someone is showing especially severe dementia-related problems at the time of diagnosis, this usually leads to an earlier death. Someone who wanders, is prone to falling, and experiences urinary incontinence , will typically not live as long. A lower mini-mental state examination score at the time of diagnosis will also not live as long. Other Health Problems. A person with a history of heart problems or asthma or diabetes, for example, will not live as long as someone without those underlying issues.

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.

How Do You Know What Stage Of Alzheimer’s Disease A Loved One Is In

The stages of Alzheimers disease presented in this post offer a reasonable framework from which to observe symptoms and understand the progression of the disease. Since there is no medical consensus for Alzheimers stages, as there is with cancer, it is important for caregivers to be aware of the individual symptoms and situation that their patient or loved one is experiencing. While healthcare providers may refer to a patients condition as late or early stage, any specific stage is less important than the context and understanding of what this means for care going forward.
