Alzheimer's progresses to death as brain damage destroys the ability to control basic bodily functions, leading to complications like infections (especially pneumonia from inhaling food/liquid), malnutrition, dehydration, and falls, ultimately causing systems to shut down, with pneumonia being a very common final cause. The disease erodes brain regions controlling vital functions, resulting in a gradual physical decline and loss of independence.
Late-stage Alzheimer's (severe)
In the final stage of the disease, dementia symptoms are severe. Individuals lose the ability to respond to their environment, to carry on a conversation and, eventually, to control movement. They may still say words or phrases, but communicating pain becomes difficult.
By the late stage, the symptoms of all types of dementia become very similar. The later stage of dementia tends to be the shortest. On average it lasts about one to two years.
The rate of progression for Alzheimer's disease varies widely. On average, people with Alzheimer's disease live between three and 11 years after diagnosis. But some live 20 years or more.
Signs of the dying process
lose consciousness. be unable to swallow. become agitated or restless. develop an irregular breathing pattern.
Injuries from falls are common. Difficulty in swallowing makes eating and drinking an ongoing challenge, and can lead to weight loss, malnutrition and dehydration. The most common cause of death among Alzheimer's patients is aspiration pneumonia.
Terminal lucidity, or “the surge,” is an unexpected episode (occurrence) of clarity and energy before death. Neurodegenerative conditions that lead to dementia, like Alzheimer's disease, cause irreversible mental decline that can be hard to watch in a loved one.
The 7 stages of Alzheimer's disease, based on the Global Deterioration Scale (GDS), describe a progression from no noticeable decline to severe dementia, encompassing stages like normal function, very mild decline (age-related forgetfulness), mild decline (noticeable difficulties), moderate decline (early dementia), moderately severe decline, severe decline, and very severe decline (severe dementia). Stages 1-3 are considered pre-dementia, while 4-7 are the dementia stages, with increasing loss of independence.
However, people with Alzheimer's don't need a special class to be able to enjoy memories sparked by music. You could play some recorded music for them or even suggest that they sing along with you. You could also buy a simplified music player designed for people with dementia.
Overall, know that Alzheimer's disease is a specific disease, while dementia is a general term for a group of similar diseases, of which Alzheimer's is one. In other words, every case of Alzheimer's disease is an example of dementia, but not every type of dementia is Alzheimer's.
'Aspiration pneumonia' is a type of pneumonia caused by food or drink going down the windpipe instead of the food pipe and is one of the most common causes of death in people with dementia.
Often, hospice and palliative care programs can help coordinate care, get referrals, and provide additional resources. In the final stages of Alzheimer's, a person may not be able to tell you that they are in pain. Instead, people with Alzheimer's may express pain with groans or sighs and may grimace when touched.
Family history. The genes you inherit from your parents can contribute to your risk of developing Alzheimer's disease, although the actual increase in risk is small. But in a few families, Alzheimer's disease is caused by the inheritance of a single gene and the risks of the condition being passed on are much higher.
A person with late-stage Alzheimer's disease can become bedridden or chair-bound. This inability to move around can cause skin breakdown, pressure sores and "freezing" of joints. To keep skin and body healthy: Relieve body pressure and improve circulation.
It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
Patients with dementia or Alzheimer's are eligible for hospice care when they show all of the following characteristics: Unable to ambulate without assistance. Unable to dress without assistance. Unable to bathe properly.
Alzheimer's disease does not change a person's need for love and affection, but it changes many aspects of a relationship. You may lose the companionship of someone who has been close and important to you. You'll need to find different ways to express your feelings.
Types of Comfort Items for Dementia Patients
Of those living alone, nearly two-thirds (62%) of people with dementia reported feeling lonely.
You Miss Out on Sleep
You do a few things you know you shouldn't -- we all do. But some of those bad habits can take a toll on your brain. For example, lack of sleep may be a cause of dementia, including Alzheimer's disease. It's best to have regular sleeping hours.
Donepezil (Aricept) is approved to treat all stages of the disease. It's taken once a day as a pill. Galantamine is approved to treat mild to moderate Alzheimer's disease. It's taken as an extended-release pill once a day or as a pill or liquid twice a day.
The term "sundowning" refers to a state of confusion that occurs in the late afternoon and lasts into the night. Sundowning can cause various behaviors, such as confusion, anxiety, aggression or ignoring directions. Sundowning also can lead to pacing or wandering. Sundowning isn't a disease.
People with dementia may experience difficulty eating, swallowing, and drinking as the disease progresses. Although this behavior can occur at any stage of the disease, it tends to be most common in the late stages. In late-stage dementia, the difficulty in swallowing limits the intake of food and drinks.
When someone is dying, their heartbeat and blood circulation slow down. The brain organs receive less oxygen than they need and so work less well. In the days before death, people often begin to lose control of their breathing. It's common for people to be very calm in the hours before they die.
It's not always a good idea for someone with dementia to be involved in the formal part of the funeral. It can be extremely upsetting and intense if they forget that their loved one has died and then are reminded of it again at the funeral.
