How Does Alzheimer’s Disease Affect The Brain
Scientists continue to unravel the complex brain changes involved in Alzheimers disease. Changes in the brain may begin a decade or more before symptoms appear. During this very early stage of Alzheimers, toxic changes are taking place in the brain, including abnormal buildups of proteins that form amyloid plaques and tau tangles. Previously healthy neurons stop functioning, lose connections with other neurons, and die. Many other complex brain changes are thought to play a role in Alzheimers as well.
The damage initially appears to take place in the hippocampus and the entorhinal cortex, which are parts of the brain that are essential in forming memories. As more neurons die, additional parts of the brain are affected and begin to shrink. By the final stage of Alzheimers, damage is widespread and brain tissue has shrunk significantly.
Alzheimers Is The Most
- Retirees are more fearful of Alzheimers than infectious diseases such as COVID-19, as well as cancer, strokes or heart attacks.
- Findings showed one-in-three of retirees listed Alzheimers as the chronic disease they feared most, 11 points higher than cancer and 13 points more than contagious diseases such as COVID-19.
The Burden On Caregivers
The increase of Alzheimers deaths and those deaths occurring at home has increased the burden on caregivers. In the final stages of Alzheimers disease, people with the disease require constant care regardless of the setting due to declines in memory, thinking, and the ability to solve problems as well as difficulties with everyday activities like bathing, feeding, and moving around the house. This means that both paid and unpaid caregivers are likely faced with increased burden and strains. Therefore, there is a large need for education programs, breaks for caregivers, and case management services, to help caregivers. These activities, programs and services can lessen the potential burden of caregiving and improve the care for those with Alzheimers disease.

Stage : Moderate Dementia
Patients in stage 5 need some assistance in order to carry out their daily lives. The main sign for stage 5 dementia is the inability to remember major details such as the name of a close family member or a home address. Patients may become disoriented about the time and place, have trouble making decisions, and forget basic information about themselves, such as a telephone number or address.
While moderate dementia can interfere with basic functioning, patients at this stage do not need assistance with basic functions such as using the bathroom or eating. Patients also still have the ability to remember their own names and generally the names of spouses and children.
Trends In Dementia Caregiving
There is some indication that families are now better at managing the care they provide to relatives with dementia than in the past. From 1999 to 2015, dementia caregivers were significantly less likely to report physical difficulties and financial difficulties related to care provision. In addition, use of respite care by dementia caregivers increased substantially . However, as noted earlier, more work is needed to ensure that interventions for dementia caregivers are available and accessible to those who need them. A 2016 study of the Older Americans Act’s National Family Caregiver Support Program found that over half of Area Agencies on Aging did not offer evidence-based family caregiver interventions.

Signs And Stages Of Dementia
In the early stages of dementia, subtle signs begin to present themselves. The person might lose their keys more often, forget directions when driving, or show mood swings. It can often be overlooked and unnoticed as simple ditziness or having an off day.
It can be hard to diagnose dementia in the earlier stages. According to the Global Deterioration Scale , dementia experts express the need for updated testing as its much better for the individual, caregivers, and family members to catch dementia earlier on. It can be confusing to pinpoint the onset of dementia as it often occurs with co-existing conditions, such as a stroke or physical disease.
Top traits of the early phase of dementia include:
- Confusion when trying to arrange difficult thoughts or tasks
As dementia progresses, the middle stage shows more severe signs of the beginning stage. The person will likely begin forgetting peoples names, faces, and their relationship to them. This relationship memory gap can come and go at different times, depending on the day.
They may also get easily lost in places like their local grocery store, nursing home, or even their own house. Communication can become an issue as they struggle to find the right words to express what they want to say. Major behavioral changes can occur, such as an introvert becoming suddenly extroverted and risk-seeking, or a nurturing friend becoming hostile toward peers.
Characteristics of mid-stage dementia:
Managing Alzheimer’s Disease Behavior
Common behavioral symptoms of Alzheimers include sleeplessness, wandering, agitation, anxiety, and aggression. Scientists are learning why these symptoms occur and are studying new treatments drug and nondrug to manage them. Research has shown that treating behavioral symptoms can make people with Alzheimers more comfortable and makes things easier for caregivers.

Alzheimers Is The Only Top
- 1 in 3 seniors dies with Alzheimers or another dementia, killing more than breast and prostate cancer combined.
- Alzheimers disease is listed as the sixth leading cause of death in the U.S. States, but it may cause more deaths than is recognized by official sources.
- The COVID-19 pandemic caused Alzheimers deaths to increase by approximately 16% more than expected.
- Deaths due to Alzheimers between 2000 and 2019 have more than doubled, increasing 145%. During the same time period, deaths from heart disease increased 7.3%.
When Do Dementia Patients Stop Eating
When a patient stops or refuses to eat, things can be very depressing for the caregiver. Drinking and eating are complex and have to do with a control center that is within the brain, which controls the muscles in the throat and neck area.
Dementia affects this part of the brain as it progresses and things like choking, coughing, grimacing as one swallows, clearing the throat, movements that are exaggerated, especially of the tongue and mouth, refusing to swallow, and spitting the food can be seen. This usually happens in the later stages of the disease.

End Of Life Dementia Care And Covid
Older adults and people with serious underlying medical conditions are at higher risk for severe illness from COVID-19. Older adults also have the highest rates of dementia. Given the risks that older adults face from both COVID-19 and dementia, its important to understand how to protect yourself and your loved one. Find more information about dementia and COVID-19 from the CDC.
When a dementia like Alzheimers disease is first diagnosed, if everyone understands that there is no cure, then plans for the end of life can be made before thinking and speaking abilities fail and the person with Alzheimers can no longer legally complete documents like advance directives.
End-of-life care decisions are more complicated for caregivers if the dying person has not expressed the kind of care he or she would prefer. Someone newly diagnosed with Alzheimers disease might not be able to imagine the later stages of the disease.

How Many People Die From Dementia
Based onthe most recent research, nearly 6.2 million Americans over 65 suffer from dementia.
In 2019 alone, there were 121,499 deaths recorded as a result of this disease, earning it a top spot in the leading causes of death in Americans over 65.
These stark numbers likely underscore the reality of the issue. Unfortunately, as dementia progresses, people often die from infections or other secondary complications that official reports may not attribute to dementia.

Alzheimers disease is a progressive brain disorder that causes dementia, destroying memory, cognitive skills, the ability to care for oneself, speak and walk, said Ruth Drew, director of family and information services at the Alzheimers Association.And since the brain affects everything, Alzheimers ultimately affects everything, she said, including the ability to swallow, cough and breathe.
Once patients reach the advanced stages of Alzheimers, they may stop eating and become weak and susceptible to infections, said Dr. Jason Karlawish, a professor of medicine at the University of Pennsylvania. Unable to swallow or cough, they are at high risk of choking, aspirating food particles or water into the lungs and developing pneumonia, which is often the immediate cause of death, he said.
You see a general decline in the contribution the brain makes, not just in thinking, but in maintaining the bodys homeostasis, Dr. Karlawish said. Using a feeding tube to nourish patients and hospitalizing them for infections does not significantly extend life at the advanced stages of the disease and is discouraged because it can prolong suffering with no hope of recovery, he said.

More Deaths From Alzheimers Disease And Other Dementias In 2020 Report Says
A year ago, Marc and Kathy Cochran were looking forward to a summer trip to Greece. Kathy, 68, had been diagnosed with early-onset Alzheimers disease in 2012, but she was functioning well and enjoying herself, which her husband of 48 years attributed to regular exercise and an active and varied social life.
That crashed to a halt when the novel coronavirus hit. The couple stopped going to restaurants, visiting friends or seeing their adult children. They even had to stop walking their dogs because the gregarious Kathy liked to run up and hug her neighbors and did not understand why that had become unsafe.
The changes put her into a tailspin. It was just like the bottom dropped out, Marc said. I couldnt get her to be calm. In the ensuing months, her cognitive function declined so precipitously that she was moved to a memory-care facility, and she died in September.
Her husband blames the pandemic. I cant tell you that she wouldnt have, but I could see a definite demarcation point from the time we shut down to the time she had to go into memory care, he said. One of the things that made her happy was seeing people, smiling at them, laughing with them, hugging them, and when she couldnt do that … she would become agitated.
About 40 percent of covid-19 deaths in the United States have been residents or staffers of long-term-care facilities, said the report, which is the organizations annual Facts and Figures assessment.

Can You Die From Dementia And How Does It Kill You
Many people worry about developing dementia one day. However, experts say there are things you can do to by more than 30 percent. In this article, we’ll cover some of the easy lifestyle changes you can make to improve your odds of staying healthy.
If you have dementia, you may be wondering what it might mean for your long-term health. Know that it’s not the type of disorder that can shorten your life expectancy, but it may make you more susceptible to contracting certain illnesses. We’ll talk about that in more detail later on, and we’ll share some suggestions to ease your fears and worries.
What Will Cause Death?
For many, dementia is unfathomable. It’s scary to think about losing memories and the ability to function normally. If you have been diagnosed with dementia, know someone who has, or are just curious about the subject, you may wonder how a person with dementia dies.
It’s possible that you could die from complications of dementia, but you’re unlikely to die from the disease itself. For example, dementia could damage your brain over time to the point that you lose the ability to breathe and therefore die. However, for many patients, this is not the case.
Even though there are around 50 million people worldwide who have dementia, you’re not destined to get it. There are billions of people who don’t have it and who will never get it.
What Is Alzheimers Disease
- The most common form of dementia, which is general term for a decline in mental ability severe enough to interfere with daily life.
- A progressive disease beginning with mild memory loss possibly leading to loss of the ability to carry on a conversation and respond to the environment.
- Involves parts of the brain that control thought, memory, and language.
- Can seriously affect a persons ability to carry out daily activities.1

Pandemic Concerns Disrupt Alzheimerscare
As Alzheimers patients lose more mental capacity, they depend more on family, friends, and professional caregivers. But the infectious virus has interfered with regular care and limited patients’ contact with other people. In many cases, these individuals may not be getting optimal medical attention.
To protect against infection, some family members and caregivers have not been able to see loved ones as much, so they have not been there to recognize symptoms of delirium and other problems, says , a neurologist at the McCance Center for Brain Health at Massachusetts General Hospital, in the Boston area, who also serves on the advisory board for the Womens Alzheimers Movement. A lot of care facilities are understaffed, and nurses and health aides have been stretched to the max.
A complicating factor, according to Dr. Fillit, is that Alzheimers patients require more hands-on care with things like dressing, bathing, toileting, and eating as their mental functions deteriorate, and this type of physical attention puts individuals at greater risk of contracting COVID-19.
As a way to help prevent person-to-person transmission of the virus, Sherzai and other healthcare providers have been seeing patients through Zoom, but he believes patient healthcare can suffer when its not delivered in person. Im not physically checking them, he says. Im not seeing blood pressure, arrhythmias, weight loss, and other factors that accumulate over time.
Can People Recover From Dementia
Unfortunately, theres no cure for dementia or Alzheimers disease, though many studies are underway. In the meantime, its essential to understand howto help a loved one who has been diagnosed with dementia.
So, can a person die from dementia? Unfortunately, yes.
However, this doesnt mean that those struggling are without hope or help. Educating yourself about thecomplications of dementia and causes of death in Alzheimers patients is a significant first step toward helping your loved one live as full a life as possible.

Medications To Treat The Underlying Alzheimer’s Disease Process
Aducanumab is the first disease-modifying therapy approved by the FDA to treat Alzheimers disease. The medication helps to reduce amyloid deposits in the brain and may help slow the progression of Alzheimers, although it has not yet been shown to affect clinical outcomes such as progression of cognitive decline or dementia. A doctor or specialist will likely perform tests, such as a PET scan or analysis of cerebrospinal fluid, to look for evidence of amyloid plaques and help decide if the treatment is right for the patient.
Aducanumab was approved through the FDAs Accelerated Approval Program. This process requires an additional study after approval to confirm the anticipated clinical benefit. If the follow-up trial fails to verify clinical benefit, the FDA may withdraw approval of the drug. Results of the phase 4 clinical trial for aducanumab are expected to be available by early 2030.
Several other disease-modifying medications are being tested in people with mild cognitive impairment or early Alzheimers as potential treatments.
Greater Risks Of Alzheimers And Dementia For Blacks And Latinos
18.6% of Blacks and 14% of Hispanics age 65 and older have Alzheimers compared with 10% of White older adults .
- Other prevalence studies also indicate that older Blacks are about twiceas likely to have Alzheimers or other dementias as older Whites.

Risk Factors And Prevention
Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of biological ageing. Further, dementia does not exclusively affect older people young onset dementia accounts for up to 9% of cases. Studies show that people can reduce their risk of cognitive decline and dementia by being physically active, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels. Additional risk factors include depression, social isolation, low educational attainment, cognitive inactivity and air pollution.
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
- sleep more
- 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.
