The average life expectancy figures for the most common types of dementia are as follows: Alzheimer's disease – around eight to 10 years. Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years.
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.
Dementia is often called a 'life limiting' condition although people have been known to live with it for as long as 26 years after they first start showing symptoms.
In stage 6 of dementia, a person may start forgetting the names of close loved ones and have little memory of recent events.
For example, a sudden deterioration or change may be a sign that an infection has led to delirium. Or it may suggest that someone has had a stroke. A stroke is particularly common in some kinds of vascular dementia and may cause the condition to get worse in a series of 'steps'.
Vascular dementia for example is linked to things like heart disease and stroke. Both of these can be life-threatening, and could increase someone's mortality risk at any stage of dementia. The second way life expectancy can be shortened is through the degenerative nature of the symptoms of dementia.
People often live for years with dementia. While it can be difficult to think of these diseases as terminal, they do eventually lead to death. Caregivers often experience special challenges surrounding the end of life of someone with dementia in part because the disease progression is so unpredictable.
In the earlier stages, memory loss and confusion may be mild. The person with dementia may be aware of — and frustrated by — the changes taking place, such as difficulty recalling recent events, making decisions or processing what was said by others.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
I'm going to discuss five of the most basic ones here: 1) Don't tell them they are wrong about something, 2) Don't argue with them, 3) Don't ask if they remember something, 4) Don't remind them that their spouse, parent or other loved one is dead, and 5) Don't bring up topics that may upset them.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
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.
If you aren't sure which stage of dementia you or your loved one are in right now, take an online Alzheimer's test. This can help pinpoint an individual's symptoms and stage.
#4: Behavioral Changes
One of the major signs of end-stage dementia are behavioral changes, like a person's inability to respond to their environment. Additional signs of end-stage dementia behavioral changes include: The need to sleep more. Having a decreased appetite.
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.
Receiving a life-changing dementia diagnosis doesn't strip a person of their humanity or personhood. People with dementia think about the same things that any human thinks about — emotions, relationships, daily life, tasks to accomplish, and more.
Often when a person with dementia asks to go home it refers to the sense of 'home' rather than home itself. 'Home' may represent memories of a time or place that was comfortable and secure and where they felt relaxed and happier. It could also be an indefinable place that may not physically exist.
Research shows that with the right supports, people with dementia can live at home longer and with higher quality of life compared to those living at home without coordinated support, and that this support may be most impactful when introduced early.
Creutzfeldt-Jakob disease causes a type of dementia that gets worse unusually fast. More common causes of dementia, such as Alzheimer's, dementia with Lewy bodies and frontotemporal dementia, typically progress more slowly.
What is worse, Alzheimer's or dementia? It is important to understand that the difference between Alzheimer's and dementia means that one is not worse than the other. Alzheimer's disease causes dementia. A person with Alzheimer's disease has both Alzheimer's and dementia.
Detailed case reports of 124 dementia patients who experienced an episode of paradoxical lucidity were received. In more than 80% of these cases, complete remission with return of memory, orientation, and responsive verbal ability was reported by observers of the lucid episode.
