Common Forms Of Dementia

How Do You Die From Alzheimer’s?

There are many different forms of dementia. Alzheimer’s disease is the most common form and may contribute to 60-70% of cases. Other major forms include vascular dementia, dementia with Lewy bodies , and a group of diseases that contribute to frontotemporal dementia . Dementia may also develop after a stroke or in the context of certain infections such as HIV, harmful use of alcohol, repetitive physical injuries to the brain or nutritional deficiencies. The boundaries between different forms of dementia are indistinct and mixed forms often co-exist.

Are There Any Treatments

There are treatments that can help with the symptoms of some forms of dementia for a period of time, but there are currently no treatments that slow, halt or reverse the changes in the brain caused by the diseases. There are currently no treatments specifically for vascular dementia or frontotemporal dementia.

In the case of vascular dementia, a doctor may prescribe medication to treat underlying cardiovascular risk factors like high blood pressure or diabetes. Physiotherapy, speech therapy or occupational therapy may be offered to help with speech or movement problems. Non-drug treatments such as cognitive therapies may be available and can help some people with dementia to manage their symptoms.

Alzheimer’s Society has more information on treatments for dementia.

How To Cope With The Late Stages Of Alzheimer’s Disease

In the earlier stages of Alzheimer’s disease, the disease affects cognitive processes and behavior more than physical functioning.

However, in late-stage Alzheimer’s disease, the disease begins to considerably affect parts of the brain that control bodily systems, such as motor coordination, bowel, and bladder function, and even breathing. The late stage of Alzheimer’s usually requires rigorous, around-the-clock care, and it can last from several weeks to several years.

The symptoms of late-stage Alzheimer’s disease often include:

  • Increased susceptibility to infections, including skin infections
  • Difficulty walking and moving, eventually resulting in the person becoming chair-bound or bed-bound
  • Loss of the ability to communicate through words
  • Groaning, grunting, moaning
  • Total incontinence of bowel and bladder, requiring full-time assistance with toileting and hygiene
  • Increased sleeping
  • Eventual inability to sit up or hold up one’s head
  • Loss of facial expressions, including the ability to smile
  • Seizures

Individuals with Alzheimer’s disease often die of a medical complication, such as pneumonia or the flu. However, Alzheimer’s itself can be fatal even if there are no other complications, these late-stage symptoms can lead to death when patients can no longer be fed or breathe safely.

What Are The Signs That Someone With Dementia Is Dying

It is difficult to know when a person with dementia is coming to the end of their life. However, there are some symptoms that may indicate the person is at the end of their life including:

  • limited speech
  • needing help with everyday activities
  • eating less and swallowing difficulties
  • incontinence and becoming bed bound.

When these are combined with frailty, recurrent infections and/or pressure ulcers, the person is likely to be nearing the end of their life. If the person has another life limiting condition , their condition is likely to worsen in a more predictable way.

When a person gets to within a few days or hours of dying, further changes are common. These include:

  • deteriorating more quickly
  • irregular breathing
  • cold hands and feet.

These are part of the dying process, and its important to be aware of them so that you can help family and friends understand what is happening.

When a person with dementia is at the end of life its important to support the person to be as comfortable as possible until they die

Dementia symptoms and signs: Can you die from the ...

Lewy body dementia symptoms are so similar to those of other forms of dementia that LBD can be misdiagnosed. This might make more sense when you consider that there are many types of dementia.

It may help to think of dementia as one large “umbrella” that slowly robs people of their ability to think, talk, remember, and use their bodies. Many diseases crowd underneath this umbrella, including:

  • Alzheimers disease

With dementia with Lewy bodies, cognitive changes may appear earlier than, about the same time, or shortly after any physical changes surface.

Final Signs And What To Do

If it has been established that the person is now dying and they become restless, this is often referred to as terminal restlessness. It is important to recognise restlessness and report it to a doctor or nurse immediately. Restlessness could be due to pain or high temperature and needs to be relieved.

If you notice the person is restless and you think they are uncomfortable, you could try helping them move into a more comfortable position. If this does not help, seek advice as they may need pain relief. Likewise, if you notice the person is hot to touch then they may need to be cooled down by a fan or cool flannel on their forehead and given rectal paracetamol by the nurse. They may also need medication to relieve the restlessness if the above does not help.

As death approaches the persons breathing pattern can change. This is caused by the person going into unconsciousness. It is often called Cheyne-Stoke breathing. The person may have periods where they have regular breathing, then stop breathing for a few seconds. Breathing usually gets faster and there can be long gaps in between. The person who is dying is unaware of this but family members may find this quite distressing. It is important that you or another senior member of staff explain to the relatives that this is what is to be expected and that the person is unaware. It is natural.

Support Care Staff And Colleagues

It is important to remember that staff caring for a person in the last hours and days of their life may find this to be emotionally challenging or distressing. This may be especially so for those who have worked with the person for some time and who have built a meaningful relationship with that person and their family. Those newer to care work, or who have little previous experience of care at the end of life, may find this a worrying or stressful time. It is important that care staff are given support by managers and colleagues, are able to ask for advice and reassurance where needed, and have the space to acknowledge their feelings.

Common Complications Of Alzheimers Disease That Cause Death

A lack of self-awareness and self-care, prolonged confinement to a bed, feeding failure, inability to receive proper nutrition and dehydration are all factors in the development of other life-threatening health conditions in dementia patients. While brain damage associated with AD is the driving force behind the patients cognitive decline and incapacitation, these secondary illnesses and conditions are ultimately responsible for causing the patients physical decline and death.

Complications of Alzheimers disease are commonly cited as such on death certificates. Because of this, deaths with a primary cause of AD and related dementias are seriously underreported. This is especially true since dementia can go unnoticed as it progresses slowly over the course of many years. Furthermore, a significant number of patients never receive an official neurological diagnosis while alive or after they have died.

Impact On Families And Carers

Dementia: End Stage of Life

In 2019, informal carers spent on average 5 hours per day providing care for people living with dementia. This can be overwhelming . Physical, emotional and financial pressures can cause great stress to families and carers, and support is required from the health, social, financial and legal systems. Fifty percent of the global cost of dementia is attributed to informal care.

Dementia Stages Before Death

At diagnosis, most people are in either the early- or mid-stage of dementia. People with early stage dementia may be a bit forgetful, but they can still function in everyday life. They live independently many still work.

In mid-stage dementia, memory and thinking problems become more obvious. Other people notice that the affected individual is no longer operating at peak capacity. Symptoms become more pronounced as this stage progresses. Affected individuals may forget that they just ate. They may wander or get lost while walking a once-familiar route. Their sleep habits may change. Its not uncommon for people with mid-stage dementia to sleep during the day and be up most of the night.

Eventually, dementia progresses to the point where individuals can no longer control bowel and bladder function. This loss of control is directly Related to the damage occurring in the brain the cells that normally control these functions die. And as more and more cells die, symptoms worsen. In late-stage , individuals may lose the ability to walk and speak. Self-feeding becomes impossible, and as the disease progresses, many people have a hard time swallowing food or drink.

What Is Alzheimers Disease

Alzheimers is a disease marked by a progressive decline in memory, judgment, language skills, and other mental abilities. In its later stages, Alzheimers may affect essential functions such as swallowing or breathing. This form of dementia usually affects older people, though some adults under 65 may be diagnosed with early-onset Alzheimers.

The cause of Alzheimers isnt known, but genetics and changes in the brain play important roles. Unfortunately, theres still no cure.

To understand what usually causes death in Alzheimers patients, you must consider the main issues that arise from this disease.

Medical Interventions In Late

If someone is in the later stages of dementia and becomes seriously ill, there may be discussion about whether to actively treat their illness. Ways of intervening may include resuscitation after a heart attack, antibiotic treatment for pneumonia, or giving food or liquids by mouth.

Giving or withholding treatment is a serious decision to make for someone else and is not an easy one to make. You need to consider:

Sometimes the decision can only be made by a guardian appointed by a tribunal or court. Each state and territory has different regulations but medical staff or Dementia Australia can advise you about appropriate contacts.

Gene Wilder’s Death: How Do People Die From Alzheimer’s

How does a person die from dementia? | Can dementia kill?

29 August 16

Legendary comedic actor Gene Wilder has died at age 83 from complications of Alzheimer’s disease, his family announced today. But what exactly does it mean to die from Alzheimer’s?

Although Alzheimer’s disease shortens people’s life spans, it is usually not the direct cause of a person’s death, according to the Alzheimer’s Society, a charity in the United Kingdom for people with dementia. Rather, people die from complications from the illness, such as infections or blood clots.

Alzheimer’s is a progressive brain disease in which abnormal protein deposits build up in the brain, causing brain cells to die. The illness is best known for causing memory loss, but it also has other debilitating effects on the body, and can affect people’s ability to move and eat by themselves. There is no cure for the illness.

Alzheimer’s patients may have difficulty swallowing, and they may inhale food, which can result in aspiration pneumonia, Dr. Marc L. Gordon, chief of neurology at Zucker Hillside Hospital in Queens, New York, who was not involved in Wilder’s care, told Live Science in a 2014 interview. Pneumonia is listed as the cause of death in as many as two-thirds of deaths of patients with dementia, according to the Alzheimer’s Society.

Alzheimer’s patients may also become bedridden, which can increase their risk of fatal blood clots, Gordon said.

People Who Have Alzheimers Disease Need Others To Care For Them And Many Of Those Providing Care Are Not Paid For Their Time And Services

  • More than 16 million Americans, usually family and friends, provide unpaid care for someone with Alzheimers disease or dementias.10 According to the US Bureau of Labor Statistics11, that would be just shy of a tenth of the entire US workforce. In 2017, these people provided an estimated 18.5 billion hours of unpaid care, a contribution valued at more than $234 billion.1 This would be about 46% of Walmarts total revenue in 2017 12 and 10 times the total revenue of McDonalds in 2017 .13

Causes Of Alzheimer’s Disease

Alzheimer’s disease is the most common type of dementia.

Alzheimer’s disease is thought to be caused by the abnormal build-up of 2 proteins called amyloid and tau.

Deposits of amyloid, called plaques, build up around brain cells. Deposits of tau form “tangles” within brain cells.

Researchers do not fully understand how amyloid and tau are involved in the loss of brain cells, but research into this is continuing.

As brain cells become affected in Alzheimer’s, there’s also a decrease in chemical messengers involved in sending messages, or signals, between brain cells.

Levels of 1 neurotransmitter, acetylcholine, are particularly low in the brains of people with Alzheimer’s disease.

Medicines like donepezil increase levels of acetylcholine, and improve brain function and symptoms.

These treatments are not a cure for Alzheimer’s disease, but they do help improve symptoms.

Read more about treatments for dementia.

The symptoms that people develop depend on the areas of the brain that have been damaged by the disease.

The hippocampus is often affected early on in Alzheimer’s disease. This area of the brain is responsible for laying down new memories. That’s why memory problems are one of the earliest symptoms in Alzheimer’s.

Unusual forms of Alzheimer’s disease can start with problems with vision or with language.

Some independence and functionality remain intact, such as bathing and using the bathroom independently, but may require assistance dressing appropriately. They are still able to recognize and converse with close family members and friends. Many people require assistance with tasks of daily living because of significant confusion.

How Does Dementia Cause Death


We mentioned above that as dementia progresses, it can lead to an individual losing the ability to walk and eat. These two factors can cause a person with dementia to become frail and malnourished.

Frailty can lead to an increased risk of injury or falling as individuals move around independently. Malnutrition can weaken an individuals immune system and increase the risk of sickness. Contracting an acute illness like pneumonia is often fatal for someone with a weakened immune system.

Often, people with dementia pass away because their body is weak and cant fight off infection any longer. Pre-existing conditions like heart disease, high blood pressure, or diabetes can also lead to an increased death rate in individuals with dementia.

So, can you die from Alzheimers or other dementia-related diseases? Yes, but as we stated earlier, dementia often contributes to death but isnt usually the main factor.

Managing frailty and malnutrition early on is a helpful way to increase the life expectancy and overall quality of life for a loved one with dementia.

However, it can be challenging to provide full-time care to a parent or family member with dementia. Here are some resources available to you as you navigate caring for a loved one with dementia.
