How Long Do People With Alzheimers Live

What are the last days before death like? | Signs of approaching death

The prognosis for Alzheimers disease is generally poor. The course of the disease varies from person to person. But on average, people with AD over 65 die within four to eight years of the diagnosis. However, some people may live up to 20 years after the first symptoms appear.

Common causes of death include:

Common Types Of Dementia

Most people who have dementia experience problems with cognitive skills, depression, indifference, and a lack of interest in doing things.

People with Lewy body dementia and Alzheimer’s disease may have similar early symptoms. Memory loss is common in both conditions, for example. Lewy body dementia also commonly causes fluctuations in arousal, hallucinations, sleep problems, and difficulty walking.

In contrast, people in the early stages of frontotemporal dementia usually don’t have memory problems. Instead, they might have obvious changes in personality and behavior.

Vascular dementia, which occurs as a result of having many strokes throughout the brain, can cause problems understanding concepts, emotional and personality changes, and memory problems. This type of dementia may accompany other types, making the decline more severe.

And chronic traumatic encephalopathy , which occurs after repeated head trauma, often begins to cause symptoms years after the traumatic brain injuries, with a significant progression of mood changes, personality changes, and a decline in memory and cognitive skills.

With Lewy body dementia, frontotemporal dementia, vascular dementia, and CTE, the memory problems may respond to cues/reminders, while in Alzheimer’s there is often a forgetting of recent events altogether.

In the final stage of all types of dementia, a person goes through a major decline in everyday functioning.

How Alzheimers Is Diagnosed By A Doctor

At one time, an Alzheimers diagnosis was only able to be confirmed after a person had passed away and doctors were able to perform an autopsy on the brain. Today, however, a physician can diagnose the disease with 90% accuracy while the person is still living.

It is important to note that there is no single test that can diagnose Alzheimers or dementia.

A medical evaluation will often include the following:

Support For Families And Alzheimers Disease Caregivers

Caring for a person with Alzheimers can have significant physical, emotional, and financial costs. The demands of day-to-day care, changes in family roles, and decisions about placement in a care facility can be difficult. NIA supports efforts to evaluate programs, strategies, approaches, and other research to improve the quality of care and life for those living with dementia and their caregivers.

Becoming well-informed about the disease is one important long-term strategy. Programs that teach families about the various stages of Alzheimers and about ways to deal with difficult behaviors and other caregiving challenges can help.

Good coping skills, a strong support network, and respite care are other things that may help caregivers handle the stress of caring for a loved one with Alzheimers. For example, staying physically active provides physical and emotional benefits.

Some caregivers have found that joining a support group is a critical lifeline. These support groups enable caregivers to find respite, express concerns, share experiences, get tips, and receive emotional comfort. Many organizations sponsor in-person and online support groups, including groups for people with early-stage Alzheimers and their families.

Signs Of Dying In The Elderly With Dementia


Dementia is a general term for a chronic or persistent decline in mental processes including memory loss, impaired reasoning, and personality changes. Alzheimers disease is the most common form of dementia, accounting for 60-80% of all cases of dementia. It is also the 6th leading cause of death in the United States, and over 5 million Americans are currently living with Alzheimers disease.

Alzheimers disease and most progressive dementias do not have a cure. While the disease inevitably worsens over time, that timeline can vary greatly from one patient to the next.

Caring for a loved one can be challenging and stressful, as the individuals personality changes and cognitive function declines. They may even stop recognizing their nearest and dearest friends and relatives. As dementia progresses, the individual will require more and more care. As a family caregiver, its important to be able to recognize the signs of dying in elderly with dementia. Hospice can help by offering care wherever the individual resides, providing physical, emotional and spiritual care to the patient and support their family.

Future Research On Alzheimers Diagnosis

Medical News Today also spoke with Dr. David A. Merrill, a psychiatrist and director of the Pacific Neuroscience Institutes Pacific Brain Health Center at Providence Saint Johns Health Center in Santa Monica, CA, about this study.

He stated this is important work in providing new options for early diagnosis and detecting Alzheimers disease before symptoms begin.

When patients havent yet started to have memory loss, thats the best point in time to intervene to prevent memory loss from occurring, Dr. Merrill explained. With a typical clinical diagnosis of Alzheimers disease, once somebodys already symptomatic it may be too late to prevent significantly impairing memory loss. Studies in years past have shown with a clinical diagnosis of Alzheimers, up to 90% of the memory cells in the brain have already died.

For the next steps in this research, he said he would like to see further validation of the test on a larger sample across all stages of the disease, from pre-symptomatic to mild cognitive impairment to more severe forms of the disorder that are already developed.

It would also be interesting to see if any available interventions decrease the oligomers, Dr. Merrill continued. How will this biomarker change in response to an intervention would be interesting to see. And do the patients get better with the treatments?

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. Can Alzheimers Be Diagnosed Before Death

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.

What Are The Signs And Symptoms Of Alzheimers Disease

The signs and symptoms of Alzheimers disease vary based on the stage of the condition. In general, the symptoms of AD involve a gradual decline in some, most or all of the following:

  • Understanding visual form and space relationship.
  • Behavior and personality.

People with memory loss or other signs of Alzheimers may have difficulty recognizing their mental decline. These signs may be more obvious to loved ones. Anyone experiencing dementia-like symptoms should see a healthcare provider as soon as possible.

Symptoms of the mild stage of Alzheimers dementia

Symptoms of AD become noticeable in the mild stage. The most common early symptom is forgetting newly learned information, especially recent events, places and names.

Other signs and symptoms of mild Alzheimers include:

  • Having difficulty finding the right words to express thoughts.
  • Losing or misplacing objects more than usual.
  • Having difficulty making plans or organizing.
  • Having difficulty problem-solving.
  • Taking longer to complete routine daily tasks.

Most people in the mild stage of AD have no problem recognizing familiar faces and can usually travel to familiar places.

Symptoms of the moderate stage of Alzheimers

Moderate Alzheimers is typically the longest stage and can last many years. People in the moderate stage of Alzheimers often require care and assistance.

People in this stage may:

How Alzheimer’s Disease Is Diagnosed

An accurate, early diagnosis of Alzheimer’s disease allows appropriate treatment to begin sooner, which is why it’s important to schedule an evaluation if you or someone you know is showing some of the signs and symptoms. The healthcare provider will do screening assessments as well as review symptoms and medical history, but may also consider imaging to rule out other possible explanations for what one is experiencing.

While you can’t diagnose yourself or someone else with Alzheimer’s disease, you can perform a clinically supported at-home check that may point to the possibility and give the practitioner useful information to use in their assessment.

What Are The Symptoms Of Alzheimers Disease

Early Onset Alzheimer

Early on, Alzheimers disease may be hard to notice. The first signs are usually memory loss and difficulty finding the right words for everyday things. However, many people have trouble with memory but dont have Alzheimers so its important to visit a doctor to work out the exact cause of memory problems.

Other common symptoms of Alzheimers disease include:

  • vagueness in daily conversation

Alzheimers disease is sometimes classified into 3 stages, based on the severity of symptoms:

  • Mild Alzheimers disease: early signs of dementia, no additional support is usually needed.
  • Moderate Alzheimers disease: symptoms are difficult to cope with and support is likely to be required.
  • Advanced Alzheimers disease: continuous care in all daily activities may be needed.
  • Symptoms will progress differently between people, depending on what areas of the brain are affected. A persons symptoms may also change from day to day and can become worse with stress, illness or tiredness.

    Pathologic Staging Of Alzheimer’s Disease

    Neuritic plaques of Aβ and neurofibrillary tangles of tau are the two hallmark microscopic features of Alzheimer’s Disease . Various approaches have been used to assess the patterns of progression of these lesions in the brain and to understand the relationship between them and the emergence of changes in memory and other symptoms of dementia. It is important to understand that Alzheimerâs disease begins many years before the symptoms of dementia appear â examination of the brain can show early findings of the disease when there was no impairment during life.

    The most commonly used criteria for evaluating AD are summarized below:

    Amyloid distribution

    This approach maps the distribution of deposits of amyloid across the brain. The progression of deposits starts in the neocortex and hippocampus and gradually spreads to deep structures involved in control of movement and eventually throughout much of the brain. In general, the more of the brain is involved, the greater the likelihood of impairment.

    Braak and Braak Stage

    This approach evaluates primarily the distribution of neurofibrillary tangles within the brain. There are six stages, from I to VI. These criteria typically are used in the research setting. While we list the usual clinical impression that corresponds to different Braak stages, it is important realize that there many exceptions.


    Who Does Alzheimers Disease Affect

    Alzheimers disease mainly affects people over age 65. The higher your age over 65, the more likely youll develop Alzheimers.

    Some people develop Alzheimers disease before age 65 typically in their 40s or 50s. This is called early-onset Alzheimers disease. Its rare. Less than 10% of AD cases are early-onset.

    How Long Will A Person With Dementia Live For

    Dementia is a life-limiting condition, but it is very difficult to know how long someone with dementia will live for. This depends on many factors.

    If the person also has another life-limiting condition , it may be clearer how long they may live for and how they will die.

    A person may die from another condition at any stage of having dementia. Because of this, they may die before their dementia symptoms become very advanced.

    A person in the later stages of dementia may get worse slowly over many months. During this time they will usually:

    • become more frail
    • have more frequent falls or infections
    • have problems eating, drinking and swallowing
    • be more likely to need urgent medical care
    • become less mobile
    • talk less often.

    A person in the later stages of dementia is likely to have a weak immune system. This means they have a higher risk of getting infections, which in some cases can last for a long time. One of the most common causes of death for people with dementia is pneumonia caused by an infection.

    A person in the later stages of dementia may have symptoms that suggest that they are close to death, but can sometimes live with these symptoms for many months. This uncertainty makes it very difficult to plan and put things in place for the end of someones life.

    When Alzheimers Disease Could Be Diagnosed Only After Death

    Teepa Snow Discusses the Ten Early Signs of Dementia

    In 1988, Alzheimers disease was a disease defined only by its progressive dementia and characteristic post-mortem brain biopsy pattern of tangled neurological fibers and accumulation of protein clumps . 82 years after this debilitating disease was first described by Dr. Alois Alzheimer in 1906, . clinical diagnosis was uncertain, you could only diagnose it reliably with histopathology, no genes were known to be associated with it and the prevalent view was that nothing can be done about it and anyway, it is an inevitable part of ageing. So said Professor David Smith, Professor Emeritus of Pharmacology at the University of Oxford in a recent address to a global audience of vitamin B12 scientist members of CluB-12 UK, a non-profit organization recently formed to foster scientific cooperation to advance recognition, diagnosis and management of B12 related medical conditions.

    Signs Death Is Near In People With Dementia

    In the period of time leading up to the end of life, an individual with dementia may show signs that they are nearing death. They may:

  • Have more infections
  • Have difficulty showing facial expressions
  • It’s important to note that there are different types of dementia. The patterns of symptoms vary due to the specific brain changes that occur in each type.

    Can You Die From Dementia

    Dementia is usually considered a disorder affecting memory and is associated with aging. In the initial stages, this could be true. Loss of memory is one of the earliest signs of the disease.

    However, according to experts, dementia is a fatal brain failure that needs to be taken seriously like other terminal diseases that kill a patient slowly. It is not just an ailment that is associated with the elderly.

    Even though the distinction is not really known in the medical field and to the general public, it is something that needs to be considered when one has to be treated at the very end stage of the condition.

    It is believed that the fact that people are misinformed and misguided about dementia, the end stage treatment is usually made very aggressive.

    The disease progresses quite slowly and the fact that it affects so many people means that it should be taken seriously. Dementia is a collection or a consequence of different diseases like Alzheimers disease, vascular dementia, and Parkinsons disease. In later stages, you can tell the type of dementia that is affecting a certain patient.

    The patient can have eating problems, pneumonia, fever, pain, and difficulty breathing, which are all caused by the failure of the brain. In the end, dementia involves so many other parts of the body.

    It is important to appreciate that the brain is the engine of our bodies. It controls everything, including metabolism, gastrointestinal tract, the lungs, and even the heart.
