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.
Moderate Dementia – More profound memory loss, generally retaining highly learned material. The average duration is between 2 and 4 years. Severe Dementia – Severe memory loss. The average duration is 1 to 2.5 years.
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. Vascular dementia – around five years.
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.
Gradually, dementia can progress and become severe. At this stage, it often significantly impairs a person's memory. A person with severe dementia may not recognize family members. Symptoms of late-stage dementia may include an inability to communicate, walk, and control bowel and bladder function.
Severe Dementia
Signs and symptoms include weight loss, seizures, skin infections, difficulty swallowing, increased sleep, groaning, moaning or grunting, lack of bladder or bowel control.
Many dementia patients are not aware of their condition. Memory loss and a loss of cognitive abilities are fundamental symptoms of Alzheimer's disease and other types of dementia, which makes it extremely difficult for sufferers to realize that they are having problems, or to understand their condition.
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.
Corticobasal syndrome. Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disease that causes parts of a person's brain to change over time. As a result of these changes, people living with CBS can experience increased difficulty with their coordination, movement, thinking and speech.
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 stage 6 of dementia, a person may start forgetting the names of close loved ones and have little memory of recent events.
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.
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.
There is no specific “angry stage” in dementia. However, pronounced mood, personality, and cognitive function changes often appear during the middle or moderate stage of dementia.
There is currently no cure for most types of dementia – including the dementia caused by Alzheimer's disease. These types of dementia are what we call “neurodegenerative.” The progression of these dementias cannot be reversed right now; symptoms gradually get worse.
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.
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.
Moderate Stages
During moderate to severe stages, symptoms are very noticeable. Your loved one may struggle to form simple sentences or understand conversations. Slurring, stammering, repetition and use of incorrect words or phrases are common. This is a difficult time for victims of the disease and their families.
People in the early stages of dementia may understand their diagnosis and its implications. However, it is important to note that dementia affects every person differently and that symptoms vary between people. In the later stages of dementia, individuals may not be aware of their condition.
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.
The five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function.
This test consists of 15 words, which have to be learned during five trials. After every trial the respondent is asked to recall as many words as possible. After a distraction period of 20 minutes, the respondent is asked to name the words they have learned before, again.
