Everyone experiences dementia differently and the rate at which symptoms become worse varies from person to person. But with the right support when you need it, many people live independently for several years.
A diagnosis of dementia does not automatically mean that a person is incapable of living alone. Some people may be capable of living on their own for some time after the diagnosis. Others may be considered too much at risk to continue living alone, a decision that is often difficult to determine.
In stage 6 of dementia, a person may start forgetting the names of close loved ones and have little memory of recent events.
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.
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.
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.
The most common cause of death among Alzheimer's patients is aspiration pneumonia.
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.
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.
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.
Dementia is a progressive condition, meaning that it gets worse over time. The speed of deterioration differs between individuals. Age, general health and the underlying disease causing brain damage will all affect the pattern of progression. However, for some people the decline can be sudden and rapid.
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.
Most dementia patients prefer to stay in their own home as long as possible. This is usually feasible in the early stages of the disease when the individual only requires basic care, such as food preparation, assistance with personal care and cleaning, and other household tasks.
Providing the person doesn't appear to be uncomfortable or distressed, then sleeping more during the day isn't normally a reason to be worried. However, if a person is lying down in bed and asleep for most of the time they will need to be looked after to make sure they don't develop any physical health problems.
Sleeping more and more is a common feature of later-stage dementia.
People with dementia think about the same things that any human thinks about — emotions, relationships, daily life, tasks to accomplish, and more. Receiving a life-changing diagnosis of dementia does not strip a person of their humanity and personhood.
Creutzfeldt-Jakob disease (CJD) is a rare and fatal form of dementia, caused by abnormal prion proteins that are toxic to the brain.
Alzheimer's disease.
Alzheimer's disease patients have plaques and tangles in their brains. Plaques are clumps of a protein called beta-amyloid, and tangles are fibrous tangles made up of tau protein. It's thought that these clumps damage healthy neurons and the fibers connecting them.
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.
Stage seven is the final stage of the dementia progression. At this stage, most people will have no ability to speak or communicate. They will require assistance with most daily activities including walking, dressing, bathing, and toileting. This stage requires 24-hour care and assistance.
A person with dementia's abilities may change from day to day, or even within the same day. What is certain though is that the person's abilities will deteriorate; this may happen rapidly in a period of a few months or slowly over a number of years.
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.
