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.
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.
Persons with dementia lose parts of their self which can be noticed when considering symptoms such as amnesia, agnosia, aphasia, and apraxia. Their own sense of self can be preserved during the entire course of dementia partly due to the fact that their amnesia makes it difficult for them to upgrade their life story.
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.
In some cases, the short answer is no, they're not aware they have dementia or Alzheimer's. Cognitive impairment can cause people with Alzheimer's, dementia, stroke, brain tumors, and other types of damage in the brain to believe that there's nothing wrong.
It is recommended that a person with dementia be told of their diagnosis. However, a person has a right not to know their diagnosis if that is their clear and informed preference.
In stage 6 of dementia, a person may start forgetting the names of close loved ones and have little memory of recent events.
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.
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.
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.
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.
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.
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.
A person with dementia may feel agitated or irritable, fidget, tap their fingers or make other repetitive movements. They may also walk up and down, move objects around or fixate on tasks such as tidying. Or they may try to leave the house. These behaviours are known as 'restlessness'.
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.
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.
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.
Those who watched the most television daily — more than four hours — were 24% more likely to develop dementia. Those who used computers interactively (not passively streaming) more than one hour daily as a leisure activity were 15% less likely to develop dementia.
Aggression usually starts in the mid-stage of dementia. This is the time when other behaviours, such as hoarding wandering, and compulsive behaviour are also prone to develop. In most types of dementia, the aggressive symptoms occur when the patient becomes more dependent with daily activities.
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'.
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.
Older memories – which have been recalled or spoken about more often – are more firmly established than newer memories. This means that a person with dementia may forget recent events, but still be able to recall detailed memories from earlier life.
