Risk Factors For Alzheimer’s Dementia
The vast majority of people who develop Alzheimer’s dementia are age 65 or older. This is called late-onset Alzheimer’s. Experts believe that Alzheimer’s, like other common chronic diseases, develops as a result of multiple factors rather than a single cause. Exceptions are cases of Alzheimer’s related to uncommon genetic changes that increase risk.
2.7.1 Age, genetics and family history
The greatest risk factors for late-onset Alzheimer’s are older age,, genetics, and having a family history of Alzheimer’s.-
Age is the greatest of these three risk factors. As noted in the Prevalence section, the percentage of people with Alzheimer’s dementia increases dramatically with age: 3% of people age 65-74, 17% of people age 75-84 and 32% of people age 85 or older have Alzheimer’s dementia. It is important to note that Alzheimer’s dementia is not a normal part of aging, and older age alone is not sufficient to cause Alzheimer’s dementia.
- One in 10 people age 65 and older has Alzheimer’s dementia.,,
- The percentage of people with Alzheimer’s dementia increases with age: 3% of people age 65-74, 17% of people age 75-84, and 32% of people age 85 and older have Alzheimer’s dementia. People younger than 65 can also develop Alzheimer’s dementia, but it is much less common and prevalence is uncertain.

What Is Alzheimers Disease
- Alzheimers disease is the most common type of dementia.
- It is a progressive disease beginning with mild memory loss and possibly leading to loss of the ability to carry on a conversation and respond to the environment.
- Alzheimers disease involves parts of the brain that control thought, memory, and language.
- It can seriously affect a persons ability to carry out daily activities.
Common Forms Of Dementia
There are many different forms of dementia. Alzheimer’s disease is the most common form and may contribute to 6070% of cases. Other major forms include vascular dementia, dementia with Lewy bodies , and a group of diseases that contribute to frontotemporal dementia . The boundaries between different forms of dementia are indistinct and mixed forms often co-exist.

Study: Alzheimers Disease A Much Larger Cause Of Death Than Reported
The American Academy of Neurology is the world’s largest association of neurologists and neuroscience professionals, with 36,000 members. The AAN is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, concussion, Parkinson’s disease and epilepsy.
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.

‘car Talk’ Host’s Death: How Does Alzheimer’s Disease Kill
Tom Magliozzi, one of the hosts of the National Public Radio show “Car Talk,” died yesterday from complications of Alzheimer’s disease, according to news reports. But how does Alzheimer’s disease kill?
Alzheimer’s is perhaps best known for its effects on memory, but the condition is a progressive brain disease in which abnormal protein deposits build up in the brain, which causes brain cells to die.
But Alzheimer’s disease is not usually a direct cause of brain death that is, it does not suddenly cause the entire brain to cease functioning, said Dr. Marc L. Gordon, chief of neurology at Zucker Hillside Hospital in Queens, New York, who was not involved in Magliozzi’s care.
Most often, the complications of the debilitating disease are what cause the death of Alzheimer’s patients, Gordon said.
These complications include infections, such as infections of bedsores that occur when people stay in bed for prolonged periods. Alzheimer’s patients also may have difficulty swallowing, and they may inhale food, which can result in aspiration pneumonia, Gordon said. Pneumonia is listed as the cause of death in as many as two-thirds of patients with dementia, according to the Alzheimer’s Society, a charity in the United Kingdom for people with dementia.
Alzheimer’s patients also can develop fatal blood clots another complication of being bedridden, Gordon said.
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.

Stage : Moderately Severe Dementia
When the patient begins to forget the names of their children, spouse, or primary caregivers, they are most likely entering stage 6 of dementia and will need full time care. In the sixth stage, patients are generally unaware of their surroundings, cannot recall recent events, and have skewed memories of their personal past. Caregivers and loved ones should watch for:

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.
Treatment Of Alzheimer’s Dementia
2.5.1 Pharmacologic treatment
None of the pharmacologic treatments available today for Alzheimer’s dementia slow or stop the damage and destruction of neurons that cause Alzheimer’s symptoms and make the disease fatal. The U.S. Food and Drug Administration has approved five drugs for the treatment of Alzheimer’s â rivastigmine, galantamine, donepezil, memantine, and memantine combined with donepezil. With the exception of memantine, these drugs temporarily improve cognitive symptoms by increasing the amount of chemicals called neurotransmitters in the brain. Memantine blocks certain receptors in the brain from excess stimulation that can damage nerve cells. The effectiveness of these drugs varies from person to person and is limited in duration.
Many factors contribute to the difficulty of developing effective treatments for Alzheimer’s. These factors include the slow pace of recruiting sufficient numbers of participants and sufficiently diverse participants to clinical studies, gaps in knowledge about the precise molecular changes and biological processes in the brain that cause Alzheimer’s disease, and the relatively long time needed to observe whether an investigational treatment affects disease progression.

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.
Risk Factors And Prevention
Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of 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 dementia by getting regular exercise, 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, low educational attainment, social isolation, and cognitive inactivity.

The Alzheimers Disease Crisis By The Numbers
Alzheimers is not a normal part of agingit is a devastating disease.
Alzheimers disease and related dementias can be emotionally and financially ruinous for people living with the disease, their caregivers and families, and society at large. Alzheimers disease and other dementias have catastrophic healthcare, economic, and social impactsand these impacts are rapidly growing.
Someone in the United States develops Alzheimers every 60 seconds. By 2050 this is projected to be every 33 seconds.
Alzheimers disease is the most common form of dementia, a progressive brain disease that slowly destroys memories and thinking skills. Alzheimers often starts 5, 10, or even 20 years before symptoms appear. Symptoms usually start with difficulty remembering new information. In advanced stages, symptoms include confusion, mood and behavior changes, and inability to care for ones self and perform basic life tasks. Alzheimers is ultimately fatal.
The risks and ramifications extend beyond Alzheimers disease itself. People living with Alzheimers are twice as likely to get the COVID-19 virus than other people – and they also face accelerated cognitive decline from well-intended quarantine measures.
How Is Alzheimers Disease Diagnosed
Doctors use several methods and tools to help determine whether a person who is having memory problems has Alzheimers disease.
To diagnose Alzheimers, doctors may:
- Ask the person and a family member or friend questions about overall health, use of prescription and over-the-counter medicines, diet, past medical problems, ability to carry out daily activities, and changes in behavior and personality.
- Conduct tests of memory, problem solving, attention, counting, and language.
- Carry out standard medical tests, such as blood and urine tests, to identify other possible causes of the problem.
- Perform brain scans, such as computed tomography , magnetic resonance imaging , or positron emission tomography , to support an Alzheimers diagnosis or to rule out other possible causes for symptoms.
These tests may be repeated to give doctors information about how the persons memory and other cognitive functions are changing over time.
People with memory and thinking concerns should talk to their doctor to find out whether their symptoms are due to Alzheimers or another cause, such as stroke, tumor, Parkinsons disease, sleep disturbances, side effects of medication, an infection, or another type of dementia. Some of these conditions may be treatable and possibly reversible.
In addition, an early diagnosis provides people with more opportunities to participate in clinical trials or other research studies testing possible new treatments for Alzheimers.

What To Do If You Suspect Alzheimers Disease
Getting checked by your healthcare provider can help determine if the symptoms you are experiencing are related to Alzheimers disease, or a more treatable conditions such as a vitamin deficiency or a side effect from medication. Early and accurate diagnosis also provides opportunities for you and your family to consider financial planning, develop advance directives, enroll in clinical trials, and anticipate care needs.

What Do Elderly People Think About Life And Death
As we get older, death seems to be nearer than when we are younger. In as much as anyone can die regardless of age, for an older person, it seems like it is more likely to happen, especially when dealing with different health conditions that the body does not handle as it used to in the younger years.
For older persons, death does not always spell sorrow and terror, as is the case with younger people. Many of the older people are contented with what the short-term future has for them. You may think that people may get anxious as they become older, but this is not the case. Older people do not have much sadness and anxiety, especially related to death. They are actually more positive about life and death.
As we grow older, our perspective shifts. This is when you realize that things are not as they always seem. Most people fear death because they feel that they will lose the things that they have been working so hard to get over the years. However, for older people, this attachment to things acquired is not really pronounced. This is how some of the fear of death actually melts away.
When you look around you and you realize that there are things that are a part of you that will outlive you actually help in a major way. This could be the legacy we have in children or gardens planted. There are yet others who place value on their country, their religion, or families that live on even after they are gone.
Glen Campbell’s Death: How Does Alzheimer’s Kill
ByRachael Rettner08 August 2017
Country music legend Glen Campbell has died at age 81 following a long battle with Alzheimer’s disease, his family announced today.
Campbell was diagnosed with Alzheimer’s disease in 2011, at the age of 75, according to Rolling Stone. Later that year, he announced he was retiring because of his illness, and began a farewell tour that included 151 shows, Rolling Stone said.
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 Campbell’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.

Late Stage Alzheimers Disease And Death
March 11, 2010 by John Collins
Of all of the stages of Alzheimers disease, late stage progressing into end stage Alzheimers and death may be the hardest to understand. There is no other outcome for this type of dementia. Every persons journey is different and unique but the destination is the same. Death. You may ask, why do I find so many different descriptions of late stage Alzheimers Disease and death.
There are the official, accepted versions that most doctors or Alzheimers organizations will tell you. These are often are generalizations and worded to ease the reality of the what will happen. This type of information is a good introduction but Id rather hear the cold hard facts.
The official descriptions of late stage Alzheimers disease, that the end is near and finally death are based on a collection of averages. A generalization of how the average person with Alzheimers will decline and die. The truth is we are still in the stone age when it comes to understanding Alzheimers disease.
You can find more realistic descriptions here and at other blogs and forums. Often discussed are what the person with Alzheimers will go through as they approach death and and finally die. You will see that each person with Alzheimers has a unique experience. We only know what the caregivers and family members describe. Not what the Alzheimers patient experiences.
Health Environmental And Lifestyle Factors That May Contribute To Alzheimer’s Disease
Research suggests that a host of factors beyond genetics may play a role in the development and course of Alzheimer’s disease. There is a great deal of interest, for example, in the relationship between cognitive decline and vascular conditions such as heart disease, stroke, and high blood pressure, as well as metabolic conditions such as diabetes and obesity. Ongoing research will help us understand whether and how reducing risk factors for these conditions may also reduce the risk of Alzheimer’s.
A nutritious diet, physical activity, social engagement, sleep, and mentally stimulating pursuits have all been associated with helping people stay healthy as they age. These factors might also help reduce the risk of cognitive decline and Alzheimer’s disease. Clinical trials are testing some of these possibilities.
Early-life factors may also play a role. For example, studies have linked higher levels of education with a decreased risk of dementia. There are also differences in dementia risk among racial groups and sexesall of which are being studied to better understand the causes of Alzheimers disease and to develop effective treatments and preventions for all people.
