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.
Recent studies show that in the progression of Alzheimer's disease, semantic memory is affected first. We have seen that even before forgetting their memories of past events, patients show a gradual decline in their general knowledge.
In the later stages, memory loss becomes far more severe. A person may not recognize family members, may forget relationships, call family members by other names, or become confused about the location of home or the passage of time. He or she may forget the purpose of common items, such as a pen or a fork.
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.
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.
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.
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.
Playing music, having objects to touch and interact with, and hand massage can all help people with dementia in the later stages. Playlist for Life is a music and dementia charity. It promotes how music with personal meaning can help people with dementia.
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.
Individuals with dementia may experience memory difficulties, issues with their ability to think, and trouble completing daily tasks. They may be aware of their symptoms in the early stages of dementia. However, a person may lose this awareness by the late stages of dementia.
A person with dementia is more likely to have accidents, incontinence or difficulties using the toilet than a person of the same age who doesn't have dementia. For some people, incontinence develops because messages between the brain and the bladder or bowel don't work properly.
Forgetting family members or not recognizing familiar people isn't necessarily the hallmark of all types of dementia. It's actually more common in Alzheimer's disease, and much more rare in vascular dementia, a form of dementia that occurs when the brain is damaged due to blood supply problems.
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.
Alzheimer's disease does not change a person's need for love and affection, but it changes many aspects of a relationship. You may lose the companionship of someone who has been close and important to you. You'll need to find different ways to express your feelings.
Loneliness and isolation is a problem for lots of older people, but it's particularly difficult if they are also struggling with dementia. In fact, more than a third of people with dementia say they feel lonely and have lost friends, according to research by the Alzheimer's Society.
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.
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.
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.
Tiredness and concentration – tiredness can cause people with dementia to not eat or give up partway through a meal. It can also lead to other difficulties such as problems with concentration or with co-ordination. People with dementia may have difficulties focusing on a meal all the way through.
Dementia reduces the brain's ability to interpret and understand information. It also causes memory problems, which can lead to suspicion, paranoia and false ideas. If someone is unaware that their memory is poor, they may create a story or explanation in which someone or something else is blamed.
Hoarding for a person with dementia may be more likely to happen in the early and middle stages of dementia and often stems from trying to have some control in their lives.
