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

Symptoms Specific To Vascular Dementia

Vascular dementia is the second most common cause of dementia, after Alzheimer’s. Some people have both vascular dementia and Alzheimer’s disease, often called “mixed dementia”.

Symptoms of vascular dementia are similar to Alzheimer’s disease, although memory loss may not be as obvious in the early stages.

Symptoms can sometimes develop suddenly and quickly get worse, but they can also develop gradually over many months or years.

Specific symptoms can include:

  • stroke-like symptoms: including muscle weakness or temporary paralysis on one side of the body
  • movement problems difficulty walking or a change in the way a person walks
  • thinking problems having difficulty with attention, planning and reasoning
  • mood changes depression and a tendency to become more emotional

How Dementia Seems To Come And Go

In one study, charts of dementia patients were reviewed during a two-year period. The researcher scanned the charts for mentions of good days and bad days. The most common characteristics? Most of the patients lived with their caregivers . Most were recently diagnosed with mild dementia. About half were taking cholinesterase inhibitors, a category of drugs used to treat Alzheimers. Good days most often involved enhanced mood, better concentration and improved ability to perform IADLs . Bad days were characterized by increased verbal repetition, anger, irritability, forgetfulness, delusions and declining mood.

How Is Parkinson Disease Diagnosed

Parkinson disease can be hard to diagnose. No single test can identify it. Parkinson can be easily mistaken for another health condition. A healthcare provider will usually take a medical history, including a family history to find out if anyone else in your family has Parkinson’s disease. He or she will also do a neurological exam. Sometimes, an MRI or CT scan, or some other imaging scan of the brain can identify other problems or rule out other diseases.

What Is Parkinsons Disease

What is the difference between Alzheimers and Dementia ...

Parkinsons disease was described by James Parkinson nearly 100 years before Dr. Alois Alzheimer described the dementia later named Alzheimers disease . Called the shaking palsy by Parkinson, PD is diagnosed when a person shows at least two of these three symptoms: slowed movements , muscle rigidity, and tremor . We recognize many other associated signs of PD, including expressionless face, quiet speech, cramped handwriting, shuffling gait, trouble getting out of a chair, and difficulty swallowing. Many of the symptoms of idiopathic Parkinson’s disease result when certain nerve cells that produce dopamine in the brain begin to malfunction and die.

Most cases are called idiopathic, meaning the cause remains unknown, although a small number of cases are linked with poisoning , head trauma, more complex PD-like neurological disorders , or reversible toxic medication effects ,

What Is Alzheimers Disease

In Alzheimers disease, researchers believe that a buildup of unusual proteins forms plaques and tangles in the brain and causes symptoms.

These proteins surround brain cells and can affect their ability to communicate. This eventually causes damage to the cells until they can no longer function.

have found that these buildups occur in specific areas of the brain, including the hippocampus. This region plays a crucial role in long-term memory recall.

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.

Myths About Dementia And Alzheimers Disease

The right treatment and support are critical to the well-being of anyone diagnosed with any form of dementia, so its important to know fact from fiction when it comes to these common myths.

Myth: Dementia is a normal part of aging.

Fact: Dementia is a disease of the brainnot a normal part of aging. Forgetting where you put your keys is a common problem for a lot of people as they age. But signs of dementia are more than just moments of forgetfulness, according to the Centers for Disease Control and Prevention . With dementia, a person may be unable to complete ordinary tasks at home or at work, get lost in familiar places and forget the function of common items. When these symptoms appear, its time to see a doctor.

Myth: You cant reduce your risk of getting Alzheimers disease or other kinds of dementiayou either get it or you dont.

Fact: Adopting healthy habits can lower your risk of developing dementia, or at least delay the onset. Healthy body, healthy mind, says Dr. Caselli. What we can control, we should control. Though he adds that even a lifetime of healthy habits is no guarantee of protection.

Myth: Since there is no cure, theres no point in getting a diagnosis.

Myth: A diagnosis of Alzheimers or another form of dementia means life as you know it will soon end.

Myth: Coping with a family member with Alzheimers is overwhelmingly difficult.

What Increases The Risk For Dementia

23 Year Old Is Youngest To be Diagnosed With Dementia
  • AgeThe strongest known risk factor for dementia is increasing age, with most cases affecting those of 65 years and older
  • Family historyThose who have parents or siblings with dementia are more likely to develop dementia themselves.
  • Race/ethnicityOlder African Americans are twice more likely to have dementia than whites. Hispanics 1.5 times more likely to have dementia than whites.
  • Poor heart healthHigh blood pressure, high cholesterol, and smoking increase the risk of dementia if not treated properly.
  • Traumatic brain injuryHead injuries can increase the risk of dementia, especially if they are severe or occur repeatedly.

What Are The Different Types Of Dementia

Various disorders and factors contribute to the development of dementia. Neurodegenerative disorders result in a progressive and irreversible loss of neurons and brain functioning. Currently, there are no cures for these diseases.

The five most common forms of dementia are:

  • Alzheimers disease, the most common dementia diagnosis among older adults. It is caused by changes in the brain, including abnormal buildups of proteins, known as amyloid plaques and tau tangles.
  • Frontotemporal dementia, a rare form of dementia that tends to occur in people younger than 60. It is associated with abnormal amounts or forms of the proteins tau and TDP-43.
  • Lewy body dementia, a form of dementia caused by abnormal deposits of the protein alpha-synuclein, called Lewy bodies.
  • Vascular dementia, a form of dementia caused by conditions that damage blood vessels in the brain or interrupt the flow of blood and oxygen to the brain.
  • Mixed dementia, a combination of two or more types of dementia.

How Is Dementia Treated

Treatment of dementia depends on the underlying cause. Neurodegenerative dementias, like Alzheimers disease, have no cure, though there are medications that can help protect the brain or manage symptoms such as anxiety or behavior changes. Research to develop more treatment options is ongoing.

Leading a healthy lifestyle, including regular exercise, healthy eating, and maintaining social contacts, decreases chances of developing chronic diseases and may reduce number of people with dementia.

What Is Alzheimer’s Disease

Alzheimer’s disease , the most common form of dementia among older adults, is an irreversible degeneration of the brain that causes disruptions in memory, cognition, personality, and other functions that eventually lead to death from complete brain failure. Genetic and environmental factors including diet, activity, smoking, traumatic brain injury, diabetes, and other medical diseases contribute to the risk of developing this form of the disease. The hallmarks of Alzheimer’s disease are the accumulation of beta-amyloid plaques between nerve cells in the brain and neurofibrillary tangles, which are twisted fibers found inside the brain’s cells). These tangles consist primarily of a protein called tau.

Symptoms Specific To Dementia With Lewy Bodies

What is the difference between Alzheimers and Dementia ...

Dementia with Lewy bodies has many of the symptoms of Alzheimer’s disease, and people with the condition typically also experience:

  • periods of being alert or drowsy, or fluctuating levels of confusion
  • visual hallucinations
  • becoming slower in their physical movements
  • repeated falls and fainting

Dementia And Alzheimers Prevention

There are many ongoing trials regarding the prevention of dementia and Alzheimers. Individuals with genetic mutations attributed to the early-onset development of Alzheimers disease account for less than 1%, but they are the most likely to develop it.

The Dominantly Inherited Alzheimer Network conducted a clinical trial that tested whether antibodies to beta-amyloid can alleviate beta-amyloid plaque formation in the brains of patients with these genetic mutations and thereby decrease, delay, or prevent symptoms.

Investigating how to prevent Alzheimers, researchers from the Alzheimers Disease Cooperative Study conducted another clinical trialthe A4 trial . This trial tests whether antibodies to beta-amyloid can diminish the risk of Alzheimers disease in people aged 6585 who are at high risk for the disease.

Though theres no particular method to prevent dementia, the evidence is strong that people can decrease their risk by making fundamental lifestyle changes. Keeping their brains active, getting regular physical exercise, and consuming a healthy diet may lessen the risk of developing Alzheimers and other kinds of dementia.

What Causes Parkinson Disease

Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.

Is This Just A Senior Moment Or Something Else

Have you ever spent the whole morning looking for your keys? Or forgotten the reason for walking to another room? Rest assured, you are not alone. It happens to everyone and at any age. Countless factors could be to blame, including stress, poor sleep patterns, and even some medications.

Nevertheless, it tends to happen more often as you age. Why? Your brain grows older as you do. Its called cognitive aging. Some areas of the brain shrink and its processing speed slows down, so memory lapses become more frequent and problem-solving and multitasking take more effort.

These kinds of age-related difficulties are far less intrusive than that associated with Alzheimers or other neurological pathologies.

Also, it doesnt come together with other warning signs, like repeating questions or getting lost in familiar places, trouble handling money, paying bills, and completing habitual tasks, or sudden changes in mood and personality. These, instead, should all raise a red flag.

The good news is, your genetics, diet, and overall lifestyle all seem to play an important role not only in the age of your brainwhich doesnt depend much on the number of years you have livedbut also in the risk of developing diseases and disorders.

So, lets live well, address any concerns, and keep our health in check. While research makes progress and changes the games.

Conditions With Symptoms Similar To Dementia

Living with dementia

Remember that many conditions have symptoms similar to dementia, so it is important not to assume that someone has dementia just because some of the above symptoms are present. Strokes, depression, excessive long-term alcohol consumption, infections, hormonal disorders, nutritional deficiencies and brain tumours can all cause dementia-like symptoms. Many of these conditions can be treated.

How Can I Support Someone With Dementia Towards The End Of Life

Knowing the person will make it easier to provide person-centred care that is focused on what they need and want. It can help to know about their likes, dislikes and their wishes for how they want to be cared for. If the person isnt able to tell you about themselves, speak to their family, friends or other people who know them well.

Its a good idea to find out if the person has a copy of This is me , a document that records information about themselves. If you cant speak to the person, ask those close to them if they have a copy. They may have these details recorded in their care plan.

There are many ways to support someone with dementia at the end of life.

How Common Is Mixed Dementia

Autopsy studies looking at the brains of people who had dementia suggest that a most of those aged 80 and older probably had mixed dementia, caused by processes related to both Alzheimers disease and vascular disease. In fact, some studies indicate that mixed vascular-degenerative dementia is the most common cause of dementia in the elderly.

In a person with mixed dementia, it may not be clear exactly how many of a persons symptoms are due to Alzheimers or another type of dementia. In one study, about 40 per cent of people who were thought to have Alzheimers were found after autopsy to also have some form of cerebrovascular disease. Several studies have found that many of the major risk factors for vascular disease also may be risk factors for Alzheimers disease.

Researchers are still working to understand how underlying disease processes in mixed dementia influence each other. It is not clear, for example, if symptoms are likely to be worse when a person has brain changes reflecting multiple types of dementia. However, the prognosisor treatment outcome is likely to be poor if there are multiple disease processes taking place simultaneously in the person.

First Signs Of Alzheimers Disease

The earliest symptomatic stage is called mild cognitive impairment, says Dr. Caselli. Early signs include:

  • Memory loss that disrupts daily life
  • Challenges in planning or solving problems
  • Difficulty completing familiar tasks
  • New problems with words in speaking or writing
  • Misplacing items and an inability to retrace steps
  • Changes in mood and personality

What Is Dementia Exactly

Ten Early Warning Signs of Alzheimer

While its current diagnostic name is major neurocognitivedisorder, the umbrella term dementia is still universally usedmostly in the lay languageto describe a wide array of symptoms resulting from a variety of brain pathologies and injuries. Loss of memory together with impairment in thinking, reasoning, learning, and language skills intense mood swings behavioral and emotional issues and difficulties carrying out simple daily tasks all fall under its rubric.

If you are wondering what the symptoms look like in action, Shakespeares King Lear , one of the greatest tragedies in English literature, can give you quite an in-depth and faithful portrait. The 80-year-old King of Britain could have suffered from Lewy Body dementia, experts suggest. The signs are woven throughout the play: from irrational thinking, paranoia, and hallucinations, to sudden mood changes, and eventually, the inability to recognize people he knows.

King Lears madness, dementia, gets its name from two Latin words joined together: de, meaning away from, and mens, mentis, meaning mind, reason, intellect. Its usually translated as being out of ones mind.

First recorded in The Etymologies, an encyclopedia compiled around ad 600 by the archbishop of Seville, Saint Isidore , the term dementia referred to all kinds of mental and neurological diseases.

Mayo Clinic Q And A: Lewy Body Dementia And Alzheimers Disease Whats The Difference

DEAR MAYO CLINIC: Whats the difference between Lewy body dementia and Alzheimers? How is Lewy body dementia diagnosed?

ANSWER: Doctors diagnose Lewy body dementia based on the range of symptoms a person shows. Generally, a Lewy body dementia diagnosis requires an ongoing decline in thinking skills, along with two of the following: visual hallucinations, Parkinsonism or fluctuating alertness. In addition, people who have Lewy body dementia also may experience a sleep condition known as REM sleep behavior disorder, in which people act out their dreams while they sleep. They also may have instability in their blood pressure and heart rate, and the body may have difficulty controlling body temperature and sweating.

A brain disease that gets worse over time, Lewy body dementia is caused by an abnormal protein, called synuclein, which is deposited in certain nerve cells and nerve processes. These deposits are called Lewy bodies named after the physician who first identified them. In Lewy body dementia, Lewy bodies are found in the deep structures of the brain that control movement, as well as in the middle and outer structures involved in emotion, behavior, judgment and awareness.

Lewy body dementia is a complex disease, and it can be difficult to control. Currently, theres no cure. But, when treatment is carefully managed, symptoms may be reduced, so they have less effect on a persons daily functioning and quality of life.
