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.
Allow yourself space and time to grieve. Try to eat properly and get enough rest (even if you don't always manage to sleep). Take things slowly and ask for help and support if you need it. Tell people what you need – if you don't, they may not know how to help or they may not feel comfortable offering.
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.
If the person's mental abilities or behaviour changes suddenly over a day or two, they may have developed a separate health problem. 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.
In the middle stage of dementia, symptoms become more noticeable and the person will need more support in managing daily life. This stage of dementia is often the longest. On average it lasts about two to four years.
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.
Sleeping more and more is a common feature of later-stage dementia.
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.
Avoid asking too many open-ended questions about the past, as it could be stressful for a person with dementia if they can't remember the answer. While it might seem polite to ask somebody about their day, it's better to focus on what's happening in the present.
Most dementias are not passed down through the family. This page will help you understand the genetic links for different types of dementia.
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.
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.
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.
The clock-drawing test is a quick way to screen for early dementia, including Alzheimer's disease. It involves drawing a clock on a piece of paper with numbers, clock hands, and a specific time. The inability to do so is a strong indication of mental decline.
You have trouble following a conversation. You find it hard to make decisions, finish a task or follow instructions. You start to have trouble finding your way around places you know well. You begin to have poor judgment.
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.
Dementia stage 5: Moderately severe cognitive decline
At this point, a person may no longer be able to carry out normal activities of daily living (ADLs), such as dressing or bathing, or Instrumental activities of daily living (IADLs) without some caregiver assistance.
The most well-known form of dementia, Alzheimer's disease, is just one specific type of dementia, and tends to have the slowest progression of all types.
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.
Many people with Alzheimer's disease have visual problems, such as changes in color vision, and past studies have shown retinal and other changes in their eyes.
Most cases of sudden confusion and rapidly progressive dementia in an elderly person are due to delirium caused by infection. Urinary infections and pneumonia can trigger acute confusion that comes on quickly, causing people to be incoherent, muddled and disorientated.
